二、操作系统配置
1、关闭防火墙和SELINUX
[root@gbase ~]# systemctl stop firewalld
[root@gbase ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@gbase ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

[root@gbase ~]# setenforce 0
[root@gbase ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config
[root@gbase ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@gbase ~]# systemctl stop firewalld
[root@gbase ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

SELINUXTYPE=targeted
2、修改主机名
[root@gbase ~]# hostnamectl set-hostname dm8dsc1 [root@gbase ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dm8dsc1:g /etc/sysconfig/network [root@gbase ~]# echo " > 10.10.13.205 dm8dsc1 > 10.10.13.206 dm8dsc2" >> /etc/hosts [root@gbase ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.10.13.205 dm8dsc1 10.10.13.206 dm8dsc2 [root@gbase ~]# hostnamectl set-hostname dm8dsc2 [root@gbase ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dm8dsc2:g /etc/sysconfig/network [root@gbase ~]# echo " > 10.10.13.205 dm8dsc1 > 10.10.13.206 dm8dsc2" >> /etc/hosts [root@gbase ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.10.13.205 dm8dsc1 10.10.13.206 dm8dsc2
三、 安装达梦软件
3.1检查Linux(Unix)系统信息
[root@dm8dsc1 ~]# getconf LONG_BIT 64 [root@dm8dsc2 ~]# getconf LONG_BIT 64
查询操作系统release信息
[root@dm8dsc1 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.8 Beta (Maipo) [root@dm8dsc2 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.8 Beta (Maipo)
3.2创建安装用户
为了减少对操作系统的影响，用户不应该以root系统用户来安装和运行DM。用户可以在安装之前为DM创建一个专用的系统用户。
1. 创建安装用户组dinstall。
[root@dm8dsc1 ~]# groupadd dinstall [root@dm8dsc2 ~]# groupadd dinstall
2. 创建安装用户dmdba。
[root@dm8dsc1 ~]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba [root@dm8dsc2 ~]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
3. 初始化用户密码。
[root@dm8dsc1 ~]# passwd dmdba Changing password for user dmdba. New password: Retype new password: passwd: all authentication tokens updated successfully. [root@dm8dsc2 ~]# passwd dmdba Changing password for user dmdba. New password: Retype new password: passwd: all authentication tokens updated successfully.
3.3 Linux(Unix)下检查操作系统限制
在Linux(Unix)系统中，因为ulimit命令的存在，会对程序使用操作系统资源进行限制。为了使DM能够正常运行，建议用户检查当前安装用户的ulimit参数。
运行ulimit -a进行查询。如下图所示：
[root@dm8dsc1 ~]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31152 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 31152 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited [root@dm8dsc2 ~]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31152 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 31152 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
参数使用限制：
1.data seg size
data seg size (kbytes, -d)
建议用户设置为1048576(即1GB)以上或unlimited(无限制)，此参数过小将导致数据库启动失败。
2. file size
file size(blocks, -f)
建议用户设置为unlimited(无限制)，此参数过小将导致数据库安装或初始化失败。
3. open files
open files(-n)
建议用户设置为65536以上或unlimited(无限制)。
4.virtual memory
virtual memory (kbytes, -v)
建议用户设置为1048576(即1GB)以上或unlimited(无限制)，此参数过小将导致数据库启动失败。
如果用户需要为当前安装用户更改ulimit的资源限制，请修改文件/etc/security/limits.conf。
root@dm8dsc1 ~]# vi /etc/security/limits.conf dmdba soft data unlimited dmdba hard data unlimited dmdba soft fsize unlimited dmdba hard fsize unlimited dmdba soft nofile 65536 dmdba hard nofile 65536 [root@dm8dsc2 ~]# vi /etc/security/limits.conf dmdba soft data unlimited dmdba hard data unlimited dmdba soft fsize unlimited dmdba hard fsize unlimited dmdba soft nofile 65536 dmdba hard nofile 65536 [root@dm8dsc1 ~]# su - dmdba [dmdba@dm8dsc1 ~]$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31152 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 65536 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 4096 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited [root@dm8dsc2 ~]# su - dmdba [dmdba@dm8dsc2 ~]$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31152 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 65536 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 4096 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
3.4.检查系统内存与存储空间
1.检查内存
为了保证DM的正确安装和运行，要尽量保证操作系统至少1GB的可用内存(RAM)。如果可用内存过少，可能导致DM安装或启动失败。用户可以使用以下命令检查操作内存：
#获取内存总大小
[root@dm8dsc1 ~]# grep MemTotal /proc/meminfo
MemTotal: 8009068 kB
[root@dm8dsc2 ~]# grep MemTotal /proc/meminfo
MemTotal: 8009068 kB
#获取交换分区大小
[root@dm8dsc1 ~]# grep SwapTotal /proc/meminfo
SwapTotal: 8257532 kB
[root@dm8dsc2 ~]# grep SwapTotal /proc/meminfo
SwapTotal: 8257532 kB
#获取内存使用详情
[root@dm8dsc1 ~]# free -g
total used free shared buff/cache available
Mem: 7 0 6 0 0 6
Swap: 7 0 7
[root@dm8dsc2 ~]# free -g
total used free shared buff/cache available
Mem: 7 0 6 0 0 6
Swap: 7 0 7
2.检查存储空间
1) DM完全安装需要1GB的存储空间，用户需要提前规划好安装目录，预留足够的存储空间。用户在DM安装前也应该为数据库实例预留足够的存储空间，规划好数据路径和备份路径。用户可使用以下命令检查存储空间:
#查询目录/dm8可用空间 [root@dm8dsc1 ~]# mkdir /dm8 [root@dm8dsc1 ~]# chown -R dmdba:dinstall /dm8 [root@dm8dsc1 ~]# chmod -R 775 /dm8 [root@dm8dsc2 ~]# mkdir /dm8 [root@dm8dsc2 ~]# chown -R dmdba:dinstall /dm8 [root@dm8dsc2 ~]# chmod -R 775 /dm8 [root@dm8dsc1 ~]# df -h /dm8 Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 48G 5.6G 43G 12% / [root@dm8dsc2 ~]# df -h /dm8 Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 48G 5.6G 43G 12% /
2) DM安装程序在安装时将产生临时文件，临时文件需要1GB的存储空间，临时文件目录默认为/tmp。用户可以使用以下命令检查存储空间。
如下图所示：
[root@dm8dsc1 ~]# df -h /tmp Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 48G 5.6G 43G 12% / [root@dm8dsc2 ~]# df -h /tmp Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 48G 5.6G 43G 12% /
3.5.安装DM
创建目录/soft/dmsoft用来存储挂载iso文件后来显示软件包中的文
[root@dm8dsc1 ~]# cd /soft [root@dm8dsc1 soft]# unzip dm8_20211021_x86_rh6_64_ent.zip Archive: dm8_20211021_x86_rh6_64_ent.zip creating: dm8_20211021_x86_rh6_64_ent/ inflating: dm8_20211021_x86_rh6_64_ent/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso extracting: dm8_20211021_x86_rh6_64_ent/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso_SHA256.txt extracting: dm8_20211021_x86_rh6_64_ent/verinfo.txt [root@dm8dsc1 soft]# ls -lrt total 778320 drwxr-xr-x. 2 root root 132 Nov 12 13:43 dm8_20211021_x86_rh6_64_ent -rw-r--r--. 1 root root 796998047 Nov 29 10:25 dm8_20211021_x86_rh6_64_ent.zip [root@dm8dsc1 soft]# mv dm8_20211021_x86_rh6_64_ent dm8 [root@dm8dsc1 soft]# mkdir dmsoft [root@dm8dsc1 soft]# mount -t iso9660 -o loop dm8/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso /soft/dmsoft mount: /dev/loop0 is write-protected, mounting read-only [root@dm8dsc1 soft]# cd dmsoft [root@dm8dsc1 dmsoft]# ls -lrt total 790160 -r-xr-xr-x. 1 root root 2802503 Oct 21 14:04 DM8 Install.pdf -r-xr-xr-x. 1 root root 806320703 Oct 21 14:11 DMInstall.bin [root@dm8dsc2 ~]# cd /soft [root@dm8dsc2 soft]# unzip dm8_20211021_x86_rh6_64_ent.zip Archive: dm8_20211021_x86_rh6_64_ent.zip creating: dm8_20211021_x86_rh6_64_ent/ inflating: dm8_20211021_x86_rh6_64_ent/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso extracting: dm8_20211021_x86_rh6_64_ent/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso_SHA256.txt extracting: dm8_20211021_x86_rh6_64_ent/verinfo.txt [root@dm8dsc2 soft]# ls -lrt total 778320 drwxr-xr-x. 2 root root 132 Nov 12 13:43 dm8_20211021_x86_rh6_64_ent -rw-r--r--. 1 root root 796998047 Nov 29 10:25 dm8_20211021_x86_rh6_64_ent.zip [root@dm8dsc2 soft]# mv dm8_20211021_x86_rh6_64_ent dm8 [root@dm8dsc2 soft]# mkdir dmsoft [root@dm8dsc2 soft]# mount -t iso9660 -o loop dm8/dm8_20211021_x86_rh6_64_ent_8.1.2.84.iso /soft/dmsoft mount: /dev/loop0 is write-protected, mounting read-only [root@dm8dsc2 soft]# cd dmsoft [root@dm8dsc2 dmsoft]# ls -lrt total 790160 -r-xr-xr-x. 1 root root 2802503 Oct 21 14:04 DM8 Install.pdf -r-xr-xr-x. 1 root root 806320703 Oct 21 14:11 DMInstall.bin
在/soft/dmsoft目录下存在DMInstall.bin文件， DMInstall.bin文件就是DM的安装程序。在运行安装程序前，需要赋予DMInstall.bin文件执行权限。具体命令如下所示：
[root@dm8dsc1 dmsoft]# chmod 755 DMInstall.bin chmod: changing permissions of ‘DMInstall.bin’: Read-only file system [root@dm8dsc2 dmsoft]# chmod 755 DMInstall.bin chmod: changing permissions of ‘DMInstall.bin’: Read-only file system
在现实中，许多Linux(Unix)操作系统上是没有图形化界面的，为了使DM能够在这些操作系统上顺利安装，DM提供了命令行的安装方式。在终端进入到安装程序所在文件夹，执行以下命令进行命令行安装：

四、绑定UDEV
编辑/etc/udev/rules.d/99-dm-devices.rules文件
[root@dm8dsc1 dmsoft]# cd /etc/udev/rules.d/ [root@dm8dsc1 rules.d]# vi 99-dm-devices.rules ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sdd2", RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdd3", RUN+="/bin/raw /dev/raw/raw5 %N" ACTION=="add", KERNEL=="sdd4", RUN+="/bin/raw /dev/raw/raw6 %N" ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw7 %N" ACTION=="add", KERNEL=="sde2", RUN+="/bin/raw /dev/raw/raw8 %N" ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw9 %N" ACTION=="add", KERNEL=="sdf2", RUN+="/bin/raw /dev/raw/raw10 %N" ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw11 %N" ACTION=="add", KERNEL=="sdg2", RUN+="/bin/raw /dev/raw/raw12 %N" ACTION=="add", KERNEL=="raw[1-12]", OWNER="dmdba", GROUP="dinstall", MODE="660" [root@dm8dsc2 dmsoft]# cd /etc/udev/rules.d/ [root@dm8dsc2 rules.d]# vi 99-dm-devices.rules ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sdd2", RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdd3", RUN+="/bin/raw /dev/raw/raw5 %N" ACTION=="add", KERNEL=="sdd4", RUN+="/bin/raw /dev/raw/raw6 %N" ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw7 %N" ACTION=="add", KERNEL=="sde2", RUN+="/bin/raw /dev/raw/raw8 %N" ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw9 %N" ACTION=="add", KERNEL=="sdf2", RUN+="/bin/raw /dev/raw/raw10 %N" ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw11 %N" ACTION=="add", KERNEL=="sdg2", RUN+="/bin/raw /dev/raw/raw12 %N" ACTION=="add", KERNEL=="raw[1-12]", OWNER="dmdba", GROUP="dinstall", MODE="660" ~ [root@dm8dsc1 rules.d]# /sbin/udevadm trigger --type=devices --action=change [root@dm8dsc1 rules.d]# ls -lrt /dev/raw total 0 crw-rw----. 1 root disk 162, 0 Dec 8 15:37 rawctl [root@dm8dsc2 rules.d]# /sbin/udevadm trigger --type=devices --action=change [root@dm8dsc2 rules.d]# ls -lrt /dev/raw total 0 crw-rw----. 1 root disk 162, 0 Dec 8 15:37 rawctl
如果不能正常显示就重启操作系统
[root@dm8dsc1 ~]# ls -lrt /dev/raw total 0 crw-rw---- 1 root disk 162, 0 Dec 8 15:38 rawctl crw-rw---- 1 root disk 162, 5 Dec 8 15:38 raw5 crw-rw---- 1 root disk 162, 4 Dec 8 15:38 raw4 crw-rw---- 1 root disk 162, 3 Dec 8 15:38 raw3 crw-rw---- 1 dmdba dinstall 162, 2 Dec 8 15:38 raw2 crw-rw---- 1 dmdba dinstall 162, 1 Dec 8 15:38 raw1 crw-rw---- 1 root disk 162, 9 Dec 8 15:38 raw9 crw-rw---- 1 root disk 162, 8 Dec 8 15:38 raw8 crw-rw---- 1 root disk 162, 7 Dec 8 15:38 raw7 crw-rw---- 1 root disk 162, 6 Dec 8 15:38 raw6 crw-rw---- 1 root disk 162, 12 Dec 8 15:38 raw12 crw-rw---- 1 root disk 162, 11 Dec 8 15:38 raw11 crw-rw---- 1 root disk 162, 10 Dec 8 15:38 raw10 [root@dm8dsc2 ~]# ls -lrt /dev/raw total 0 crw-rw---- 1 root disk 162, 0 Dec 8 15:38 rawctl crw-rw---- 1 root disk 162, 7 Dec 8 15:38 raw7 crw-rw---- 1 dmdba dinstall 162, 2 Dec 8 15:38 raw2 crw-rw---- 1 dmdba dinstall 162, 1 Dec 8 15:38 raw1 crw-rw---- 1 root disk 162, 9 Dec 8 15:38 raw9 crw-rw---- 1 root disk 162, 8 Dec 8 15:38 raw8 crw-rw---- 1 root disk 162, 5 Dec 8 15:38 raw5 crw-rw---- 1 root disk 162, 4 Dec 8 15:38 raw4 crw-rw---- 1 root disk 162, 3 Dec 8 15:38 raw3 crw-rw---- 1 root disk 162, 11 Dec 8 15:38 raw11 crw-rw---- 1 root disk 162, 10 Dec 8 15:38 raw10 crw-rw---- 1 root disk 162, 6 Dec 8 15:38 raw6 crw-rw---- 1 root disk 162, 12 Dec 8 15:38 raw12 [root@dm8dsc1 ~]# vi /etc/rc.d/rc.local #!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. touch /var/lock/subsys/local chown dmdba:dinstall /dev/raw/raw[1-12] chmod 660 /dev/raw/raw[1-12] [root@dm8dsc1 ~]# vi /etc/rc.d/rc.local #!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. touch /var/lock/subsys/local chown dmdba:dinstall /dev/raw/raw[1-12] chmod 660 /dev/raw/raw[1-12]
修改裸设备的权限防止因为重启权限不正确导致dmasmcmd不能识别
[root@dm8dsc1 ~]# ls -lrt /dev/raw/ total 0 crw-rw---- 1 root disk 162, 0 Dec 8 16:27 rawctl crw-rw---- 1 dmdba dinstall 162, 9 Dec 8 16:27 raw9 crw-rw---- 1 dmdba dinstall 162, 10 Dec 8 16:27 raw10 crw-rw---- 1 dmdba dinstall 162, 6 Dec 8 16:27 raw6 crw-rw---- 1 dmdba dinstall 162, 5 Dec 8 16:27 raw5 crw-rw---- 1 dmdba dinstall 162, 3 Dec 8 16:27 raw3 crw-rw---- 1 dmdba dinstall 162, 2 Dec 8 16:27 raw2 crw-rw---- 1 dmdba dinstall 162, 1 Dec 8 16:27 raw1 crw-rw---- 1 dmdba dinstall 162, 8 Dec 8 16:27 raw8 crw-rw---- 1 dmdba dinstall 162, 7 Dec 8 16:27 raw7 crw-rw---- 1 dmdba dinstall 162, 4 Dec 8 16:27 raw4 crw-rw---- 1 dmdba dinstall 162, 12 Dec 8 16:27 raw12 crw-rw---- 1 dmdba dinstall 162, 11 Dec 8 16:27 raw11 [root@dm8dsc2 ~]# ls -lrt /dev/raw/ total 0 crw-rw---- 1 root disk 162, 0 Dec 8 16:26 rawctl crw-rw---- 1 dmdba dinstall 162, 1 Dec 8 16:26 raw1 crw-rw---- 1 dmdba dinstall 162, 5 Dec 8 16:26 raw5 crw-rw---- 1 dmdba dinstall 162, 2 Dec 8 16:26 raw2 crw-rw---- 1 dmdba dinstall 162, 8 Dec 8 16:26 raw8 crw-rw---- 1 dmdba dinstall 162, 7 Dec 8 16:26 raw7 crw-rw---- 1 dmdba dinstall 162, 6 Dec 8 16:26 raw6 crw-rw---- 1 dmdba dinstall 162, 4 Dec 8 16:26 raw4 crw-rw---- 1 dmdba dinstall 162, 3 Dec 8 16:26 raw3 crw-rw---- 1 dmdba dinstall 162, 11 Dec 8 16:26 raw11 crw-rw---- 1 dmdba dinstall 162, 9 Dec 8 16:26 raw9 crw-rw---- 1 dmdba dinstall 162, 12 Dec 8 16:26 raw12 crw-rw---- 1 dmdba dinstall 162, 10 Dec 8 16:26 raw10
可以通过blockdev –getsize64 /dev/raw/raw1命令查看裸设备大小
[root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw1 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw2 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw3 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw4 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw5 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw6 2147483648 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw7 5368709120 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw8 5367660544 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw9 5368709120 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw10 5367660544 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw11 5368709120 [root@dm8dsc1 ~]# blockdev --getsize64 /dev/raw/raw12 5367660544 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw1 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw2 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw3 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw4 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw5 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw6 2147483648 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw7 5368709120 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw8 5367660544 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw9 5368709120 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw10 5367660544 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw11 5368709120 [root@dm8dsc2 ~]# blockdev --getsize64 /dev/raw/raw12 5367660544
五.配置dmdcr_cfg.ini文件
在2个节点的/dm8/data目录下创建配置文件dmdcr_cfg.ini，在文件中添加如下内容：
[root@dm8dsc1 ~]# su - dmdba Last login: Wed Dec 8 15:27:56 CST 2021 on pts/1 [dmdba@dm8dsc1 ~]$ mkdir /dm8/data [root@dm8dsc2 ~]# su - dmdba Last login: Wed Dec 8 15:27:32 CST 2021 on pts/1 [dmdba@dm8dsc2 ~]$ mkdir /dm8/data [dmdba@dm8dsc1 ~]$ cd /dm8/data [dmdba@dm8dsc1 data]$ vi dmdcr_cfg.ini DCR_N_GRP = 2 DCR_VTD_PATH = /dev/raw/raw2 DCR_OGUID = 63635 [GRP] DCR_GRP_TYPE = CSS DCR_GRP_NAME = GRP_CSS DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_CSS] DCR_EP_NAME = CSS0 DCR_EP_HOST = 11.11.11.3 DCR_EP_PORT = 9541 [GRP_CSS] DCR_EP_NAME = CSS1 DCR_EP_HOST = 11.11.11.4 DCR_EP_PORT = 9541 [GRP] DCR_GRP_TYPE = DB DCR_GRP_NAME = GRP_DSC DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_DSC] DCR_EP_NAME = DSC0 DCR_EP_SEQNO = 0 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741 [GRP_DSC] DCR_EP_NAME = DSC1 DCR_EP_SEQNO = 1 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741 [dmdba@dm8dsc2 ~]$ cd /dm8/data [dmdba@dm8dsc2 data]$ vi dmdcr_cfg.ini DCR_N_GRP = 2 DCR_VTD_PATH = /dev/raw/raw2 DCR_OGUID = 63635 [GRP] DCR_GRP_TYPE = CSS DCR_GRP_NAME = GRP_CSS DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_CSS] DCR_EP_NAME = CSS0 DCR_EP_HOST = 11.11.11.3 DCR_EP_PORT = 9541 [GRP_CSS] DCR_EP_NAME = CSS1 DCR_EP_HOST = 11.11.11.4 DCR_EP_PORT = 9541 [GRP] DCR_GRP_TYPE = DB DCR_GRP_NAME = GRP_DSC DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_DSC] DCR_EP_NAME = DSC0 DCR_EP_SEQNO = 0 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741 [GRP_DSC] DCR_EP_NAME = DSC1 DCR_EP_SEQNO = 1 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741
六、使用 DMASMCMD 工具初始化（任意一节点执行）
[dmdba@dm8dsc1 ~]$ dmasmcmd DMASMCMD V8 ASM>create dcrdisk '/dev/raw/raw1' 'dcr' [Trace]The ASM initialize dcrdisk /dev/raw/raw1 to name DMASMdcr Used time: 269.118(ms). ASM>create votedisk '/dev/raw/raw2' 'vote' [Trace]The ASM initialize votedisk /dev/raw/raw2 to name DMASMvote Used time: 108.701(ms). ASM>init dcrdisk '/dev/raw/raw1' from '/dm8/data/dmdcr_cfg.ini' identified by 'dameng123' [Trace]DG 126 alloc one extent for inodes, addr(disk_id, disk_auno, extent_no):(0,0,1). [Trace]DG 126 allocate 4 extents for file 0xfe000002. [Trace]DG 126 alloc 4 extents for 0xfe000002, addr(disk_id, disk_auno, extent_no):(0, 0, 2)->(0, 0, 5), need_init = 1. Used time: 00:00:02.244. ASM>init votedisk '/dev/raw/raw2' from '/dm8/data/dmdcr_cfg.ini' [Trace]DG 125 alloc one extent for inodes, addr(disk_id, disk_auno, extent_no):(0,0,1). [Trace]DG 125 allocate 4 extents for file 0xfd000002. [Trace]DG 125 alloc 4 extents for 0xfd000002, addr(disk_id, disk_auno, extent_no):(0, 0, 2)->(0, 0, 5), need_init = 1. Used time: 431.131(ms).
七.准备dmdcr.ini 配置文件
dmdcr.ini 是 dmcss、dmasmsvr、dmasmtool 工具的输入参数。记录了当前节点序列号以及 DCR 磁盘路径。在2个节点的/dm8/data目录下创建dmdcr.ini 配置文件，dmdcr_path 相同，dmasvrmal.ini 文件内容也相同，dmdcr_seqo 分别为 0 和 1。
节点 1：
[dmdba@dm8dsc1 data]$ vi dmdcr.ini DMDCR_PATH = /dev/raw/raw1 DMDCR_SEQNO = 0 #DB DMDCR_DB_RESTART_INTERVAL = 0 DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/data/dsc0_config/dm.ini dcr_ini=/dm8/data/dmdcr.ini
节点2:
[dmdba@dm8dsc2 data]$ vi dmdcr.ini DMDCR_PATH = /dev/raw/raw1 DMDCR_SEQNO = 1 #DB DMDCR_DB_RESTART_INTERVAL = 0 DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/data/dsc1_config/dm.ini dcr_ini=/dm8/data/dmdcr.ini
八.启动DMCSS服务程序
1、注册 DMCSS
节点一:
[root@dm8dsc1 ~]# /dm8/script/root/dm_service_installer.sh -t dmcss -dcr_ini /dm8/data/dmdcr.ini -p dsc1 Created symlink from /etc/systemd/system/multi-user.target.wants/DmCSSServicedsc1.service to /usr/lib/systemd/system/DmCSSServicedsc1.service. Finished to create the service (DmCSSServicedsc1)
节点二:
[root@dm8dsc2 ~]# /dm8/script/root/dm_service_installer.sh -t dmcss -dcr_ini /dm8/data/dmdcr.ini -p dsc2 Created symlink from /etc/systemd/system/multi-user.target.wants/DmCSSServicedsc2.service to /usr/lib/systemd/system/DmCSSServicedsc2.service. Finished to create the service (DmCSSServicedsc2)
2、启动DMCSS 服务
节点一：
[root@dm8dsc1 ~]# service DmCSSServicedsc1 start
Redirecting to /bin/systemctl start DmCSSServicedsc1.service
[root@dm8dsc1 ~]# service DmCSSServicedsc1 status
Redirecting to /bin/systemctl status DmCSSServicedsc1.service

Dec 08 17:20:19 dm8dsc2 systemd[1]: Started DM Cluster Synchronization Services Service(DmCSSServicedsc2)..
九.操作系统配置准备配置dminit.ini文件，存放在/dm8/data目录中(数据文件存储在/dev/raw/raw3-6裸设备上，日志文件存储在/dev/raw/raw7-10
[dmdba@dm8dsc1 data]$ vi dminit.ini system_path = /dm8/data db_name=dsc main = /dev/raw/raw3 main_size = 128 roll = /dev/raw/raw4 roll_size = 128 system = /dev/raw/raw5 system_size = 128 ctl_path = /dev/raw/raw6 ctl_size = 8 dcr_path=/dev/raw/raw1 dcr_seqno=0 [dsc0] config_path=/dm8/data/dsc0_config port_num = 5236 mal_host = 11.11.11.3 mal_port = 9340 log_size = 256 log_path = /dev/raw/raw7 log_path = /dev/raw/raw8 [dsc1] config_path=/dm8/data/dsc1_config port_num = 5236 mal_host = 11.11.11.4 mal_port = 9341 log_size = 256 log_path = /dev/raw/raw9 log_path = /dev/raw/raw10
十、操作系统配置使用dminit初始化DB环境
在任意节点启动 dminit 工具初始化数据库。dminit 执行完成后，会在 config_path 目录（/dm8/data/dsc0_config 和/dm8/data/dsc1_config）下生成配置文件 dm.ini 和 dmmal.ini。
[dmdba@dm8dsc1 data]$ dminit control=/dm8/data/dminit.ini initdb V8 db version: 0x7000c file dm.key not found, use default license! License will expire on 2022-10-21 Normal of FAST Normal of DEFAULT Normal of RECYCLE Normal of KEEP Normal of ROLL log file path: /dev/raw/raw7 log file path: /dev/raw/raw8 log file path: /dev/raw/raw9 log file path: /dev/raw/raw10 FILE "/dev/raw/raw5" has already existed FILE "/dev/raw/raw4" has already existed FILE "/dev/raw/raw3" has already existed FILE "/dev/raw/raw6" has already existed FILE "/dev/raw/raw7" has already existed FILE "/dev/raw/raw8" has already existed FILE "/dev/raw/raw9" has already existed FILE "/dev/raw/raw10" has already existed File "/dev/raw/raw5" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw4" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw3" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw6" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw7" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw8" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw9" has already existed, whether overwrite(y/n, 1/0): y File "/dev/raw/raw10" has already existed, whether overwrite(y/n, 1/0): y write to dir [/dm8/data/dsc]. create dm database success. 2021-12-08 17:30:36 [dmdba@dm8dsc1 data]$ ls -lrt total 12 -rw-r--r-- 1 dmdba dinstall 563 Dec 8 16:49 dmdcr_cfg.ini -rw-r--r-- 1 dmdba dinstall 182 Dec 8 17:05 dmdcr.ini -rw-r--r-- 1 dmdba dinstall 546 Dec 8 17:28 dminit.ini drwxr-xr-x 2 dmdba dinstall 87 Dec 8 17:30 dsc0_config drwxr-xr-x 2 dmdba dinstall 55 Dec 8 17:30 dsc1_config drwxr-xr-x 5 dmdba dinstall 70 Dec 8 17:30 dsc
将节点一的配置文件复制到节点二：
[dmdba@dm8dsc1 data]$ scp -r dsc1_config 10.10.13.206:`pwd` The authenticity of host '10.10.13.206 (10.10.13.206)' can't be established. ECDSA key fingerprint is SHA256:6O8c9WEeEYPbL4ncdRR1RsrjxxmfzPq9Tkq4/6uLSP4. ECDSA key fingerprint is MD5:e1:73:3e:8d:79:be:5c:82:0f:c7:58:79:45:ad:df:86. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.10.13.206' (ECDSA) to the list of known hosts. dmdba@10.10.13.206's password: dmmal.ini 100% 200 17.0KB/s 00:00 dm.ini 100% 52KB 2.2MB/s 00:00 sqllog.ini 100% 481 53.4KB/s 00:00
一定要将节点一/dm8/data/目录中生成的dsc目录复制到节点二的/dm8/data目录中，否则在节点二中启动数据库时会出现以下错误，原因就是因为使用裸设备时生成的dsc目录及其文件不是存储在共享存储中可以让集群节点都能访问。

将节点一/dm8/data/目录中生成的dsc目录复制到节点二的/dm8/data目录
[dmdba@dm8dsc1 data]$ scp -r dsc 10.10.13.206:`pwd` dmdba@10.10.13.206's password: dm_20211208173029_111982.ctl 100% 6144 493.8KB/s 00:00 dm_service.prikey 100% 633 57.0KB/s 00:00
十一. 启动数据库服务器
1、在2个节点分别注册DM 数据库服务：
节点一：
[root@dm8dsc1 init.d]# /dm8/script/root/dm_service_installer.sh -t dmserver -dm_ini /dm8/data/dsc0_config/dm.ini -dcr_ini /dm8/data/dmdcr.ini -p dsc1 dmserver(RAC) need to be set the dependent service(dmasmsvr)!
提示需要依赖服务dmasmsvr，但使用裸设备没有配置dmasm实例，所以只能手动启动服务
手工启动命令如下，手工启动后窗口不能关闭
[dmdba@dm8dsc1 ~]$ dmserver /dm8/data/dsc0_config/dm.ini dcr_ini=/dm8/data/dmdcr.ini & [dmdba@dm8dsc2 ~]$ dmserver /dm8/data/dsc1_config/dm.ini dcr_ini=/dm8/data/dmdcr.ini &
如果DMCSS配置有自动拉起dmserver的功能，可以等待DMCSS自动拉起实例，不需要手动启动。在dmdcr.ini文件中配置如下选项
#DB DMDCR_DB_RESTART_INTERVAL = 10 DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/data/dsc0_config/dm.ini dcr_ini=/dm8/data/dmdcr.ini
十二.连接数据库验证
1.配置服务名文件
[dmdba@dm8dsc1 ~]$ vi /etc/dm_svc.conf TIME_ZONE=(480) LANGUAGE=(en) rac=(10.10.13.205:5236,10.10.13.206:5236) SWITCH_TIME=(10000) SWITCH_INTERVAL=(10) [dmdba@dm8dsc2 ~]$ vi /etc/dm_svc.conf TIME_ZONE=(480) LANGUAGE=(en) rac=(10.10.13.205:5236,10.10.13.206:5236) SWITCH_TIME=(10000) SWITCH_INTERVAL=(10)
2.连接RAC集群
节点一:
