mount: /dev/loop0 写保护,将以只读方式挂载
创建DM用户和目录
- root 用户登录
- 创建用户所在组
[root@localhost100 ~]# groupadd dinstall
创建用户
[root@localhost100 ~]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
-g, --gid GROUP 新账户主组的名称或 ID
-m, --create-home 创建用户的主目录
-d, --home-dir HOME_DIR 新账户的主目录
-s, --shell SHELL 新账户的登录 shell
或者
[root@localhost dm]# cd /home/
[root@localhost home]# ll
total 0
drwx------. 3 admin admin 78 Jun 13 00:13 admin
[root@localhost home]# groupadd dinstall
[root@localhost home]# useradd dmdba -g dinstall

total 0
drwx------. 3 admin admin 78 Jun 13 00:13 admin
drwx------. 3 dmdba dinstall 78 Jun 13 22:18 dmdba
- 修改用户密码
[root@localhost100 ~]# passwd dmdba
更改用户 dmdba 的密码 。
新的 密码:123456
无效的密码: 密码少于 8 个字符
重新输入新的 密码:123456
passwd:所有的身份验证令牌已经成功更新。
-
su - dmdba
将root 的 环境变量复制到dmdba用户 -
将DM安装文件复制到dmdba目录下
-
解除挂载
[root@localhost opt]# umount dm/
[root@localhost opt]# cd dm/
[root@localhost dm]# ll

drwxr-xr-x. 2 root root 6 Oct 30 2018 rh
- 修改安装目录权限
[root@localhost ~]# cd /home/dmdba/
[root@localhost dmdba]# ll
total 1066696
-r-xr-xr-x. 1 root root 1092293558 Jun 13 22:21 DMInstall.bin
[root@localhost dmdba]# chown -R dmdba:dinstall DMInstall.bin
[root@localhost dmdba]# ll
total 1066696
-r-xr-xr-x. 1 dmdba dinstall 1092293558 Jun 13 22:21 DMInstall.bin
- 给安装文件设置 755 权限。
[root@localhost dmdba]# chmod 755 DMInstall.bin
[root@localhost dmdba]# ll
total 1066696
-rwxr-xr-x. 1 dmdba dinstall 1092293558 Jun 13 22:21 DMInstall.bin
- 优化 limit 参数
vi /etc/security/limits.conf
dmdba soft core unlimited
dmdba hard core unlimited
dmdba soft nofile 102400
dmdba hard nofile 102400
dmdba soft nproc 102400
dmdba hard nproc 102400
dmdba soft stack 102400
dmdba hard stack 102400
(二)数据库安装
切换 dmdba 用户
切换至 dmdba 用户下,在目录下使用命令行安装数据库程序
root@localhost100 DM]# su dmdba
执行安装命令
[dmdba@localhost100 DM]$ ./DMInstall.bin -i
选择安装程序的语言 c/C 为中文,e/E 为英文。
提示是否安装 key 文件,输入 N 跳过。
选择时区,21 即东 8 区。
选择安装类型,默认典型安装(包含所有内容)
3.安装完成后
切换 root 用户
执行上图中的命令,会自动创建 DmAPService,否则会影响数据库备份。
[dmdba@localhost ~]$ su root
Password:
[root@localhost dmdba]# /home/dmdba/dmdbms/script/root/root_installer.sh
移动 /home/dmdba/dmdbms/bin/dm_svc.conf 到/etc目录
创建DmAPService服务
Created symlink from /etc/systemd/system/multi-user.target.wants/DmAPService.service to /usr/lib/systemd/system/DmAPService.service.
创建服务(DmAPService)完成
启动DmAPService服务
二、主库
- 初始化数据库
./dminit PATH=/home/dmdba/dmdbms/data page_size=32 extent_size=32 LOG_SIZE=2048 CHARSET=0 CASE_SENSITIVE=Y LENGTH_IN_CHAR=Y
- 注册数据库实例服务
切换到root用户下
[dmdba@localhost bin]$ su root
Password:
[root@localhost bin]# cd /home/dmdba/dmdbms/script/root/
[root@localhost root]# ll
total 44
-rwxr-xr-x. 1 dmdba dinstall 25373 Jun 14 00:44 dm_service_installer.sh
-rwxr-xr-x. 1 dmdba dinstall 9179 Jun 14 00:44 dm_service_uninstaller.sh
-rwxr-xr-x. 1 dmdba dinstall 490 Jun 14 00:44 root_installer.sh
注册服务命令:
[root@localhost root]# ./dm_service_installer.sh -t dmserver -p DMSERVER -dm_ini /home/dmdba/dmdbms/data/DAMENG/dm.ini -auto true
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServiceDMSERVER.service to /usr/lib/systemd/system/DmServiceDMSERVER.service.
创建服务(DmServiceDMSERVER)完成
卸载服务:
[root@localhost root]# ./dm_service_uninstaller.sh -n DmServiceDMSERVER
是否删除服务(DmServiceDMSERVER)?(Y/y:是 N/n:否): y
Removed symlink /etc/systemd/system/multi-user.target.wants/DmServiceDMSERVER.service.
删除服务文件(/usr/lib/systemd/system/DmServiceDMSERVER.service)完成
删除服务(DmServiceDMSERVER)完成

三、配置监视器:
1.安装数据库,把此两个文件放在 bin 下
2.配置监视器(配置业务 IP)
(1)配置 dmmonitor_auto(放在 bin 下即可)确认监视器
MON_DW_CONFIRM = 1 #0:非确认(故障手切) 1:确认(故障自切)
MON_LOG_PATH = ../log #监视器日志文件存放路径
MON_LOG_INTERVAL = 60 #每隔 60s 定时记录系统信息到日志文件
MON_LOG_FILE_SIZE = 512 #单个日志大小,单位 MB
MON_LOG_SPACE_LIMIT = 2048 #日志上限,单位 MB
[GRP1]
MON_INST_OGUID = 45331 #组 GRP1 的唯一 OGUID 值
MON_DW_IP = 192.168.113.128:5436 #IP 对应 MAL_HOST,PORT 对应 MAL_DW_PORT
MON_DW_IP = 192.168.113.130:5436
MON_DW_IP = 192.168.113.131:5436
(2)配置 dmmonitor_manual(放在 bin 下即可)普通监视器
MON_DW_CONFIRM = 0 #0:非确认(故障手切) 1:确认(故障自切)
MON_LOG_PATH = ../log #监视器日志文件存放路径
MON_LOG_INTERVAL = 60 #每隔 60s 定时记录系统信息到日志文件
MON_LOG_FILE_SIZE = 512 #单个日志大小,单位 MB
MON_LOG_SPACE_LIMIT = 2048 #日志上限,单位 MB
[GRP1]
MON_INST_OGUID = 45331 #组 GRP1 的唯一 OGUID 值
MON_DW_IP = 192.168.113.128:5436 #IP 对应 MAL_HOST,PORT 对应 MAL_DW_PORT
MON_DW_IP = 192.168.113.130:5436
MON_DW_IP = 192.168.113.131:5436
3.注册监视器守护服务(下面为一行)
[root@~]#./dm_service_installer.sh -t dmmonitor -p Monitor -monitor_ini /home/dmdba/dmdbms/bin/dmmonitor.ini
/home/dmdba/dmdbms/bin/dmmonitor_auto.ini
启动数据库并修改参数
搭建完成
四、启动数据库方式(备注:输入前三字母 Tab 补齐)
1.在数据库服务器分别:
起主服务 ./DmS (tab 补全) start, 备 ./DmS (tab 补全) start,主 ./DmW (tab 补全) start,备 ./DmW (tab 补全) start
即:先启动主库实例服务,然后启动备库实例服务;再启动主库守护进程,然后启动备库守护服务
或者:
启动数据守护服务
先主./DmW (tab 补全) start,./DmWatcherServiceGRP1_RWW_01 restart
再备./DmW (tab 补全) start,./DmWatcherServiceGRP1_RWW_02 restart
等待守护服务自动拉起实例服务,查询实例服务是否启动 (约1分钟)
ps -eflgrep dmserver
2.在监视器服务器:起确认监视器 ./DmM (tab 补全) start./DmMonitorServiceRWW start
3.查看状态,通过普通监视器(路径为 dmmonitor_manual.ini 的路径)
./dmmonitor /路径/bin/dmmonitor_manual.ini
例如:
./dmmonitor /home/dmdba/dmdbms/data/TEST/dmmonitor_manual.ini
五、停数据库方式(备注:输入前三字母 Tab 补齐)
先停确认监视器,再停备库守护,再停备库实例服务,最后再停主库守护,再停主库实例服务
关闭确认监视器:./DmMonitorServiceRWW stop
关闭备库守护服务:/DmWatcherServiceGRP1_RWW_03 stop
关闭备库实例服务:/DmServiceGRP1_RWW_03 stop
