初始化主备库
以主机 DMSVR01为读写分离主库，启动实例
dmserver /dm8/data/DM01/dm.ini
出现 system is ready 后输入 exit 停止数据库。

BACKUP DATABASE '/dm8/data/DM01/dm.ini' FULL TO BACKUP_FILE1 BACKUPSET '/dm8/backup/BACKUP_FILE_01'
拷贝备份文件到备机

启动主库
./dmserver /dm8/data/DM01/dm.ini mount
开启另一个窗口
如果是非5236端口,则要改个参数
sp_set_para_value(2,'ENABLE_ENCRYPT',0);
重启生效

启动守护进程
dmdba 用户下，到数据库安装目录的 bin 下执行以下命令（主备库都执行）：
dmwatcher /dmdata/dmdb/dmwatcher.ini
守护进程启动后，会将 Mount 的实例 Open。
注册服务
使用 root 用户，到数据库安装目录的 cd /dm8/script/root 下。
注册守护进程服务（主备库都执行）。
./dm_service_installer.sh -t dmwatcher -p DMSVR01 -watcher_ini /dm8/data/DM01/dmwatcher.ini
./dm_service_installer.sh -t dmwatcher -p DMSVR02 -watcher_ini /dm8/data/DM01/dmwatcher.ini
注册数据库实例服务（主备库都执行）：
./dm_service_installer.sh -t dmserver -p DMSVR01 -dm_ini /dm8/data/DM01/dm.ini
./dm_service_installer.sh -t dmserver -p DMSVR02 -dm_ini /dm8/data/DM01/dm.ini
执行以下命令，启动数据库实例：达梦数据库
systemctl start DmServiceDMSVR01
执行以下命令，启动守护进程：
systemctl start DmWatcherServiceDMSVR01
--standby
systemctl start DmServiceDMSVR02
执行以下命令，启动守护进程：
systemctl start DmWatcherServiceDMSVR02

执行以下命令，启动监视器：
cd /dm8/bin
./dmmonitor /dm8/data/dmmonitor.ini
--switch over

关闭确认监视器：systemctl stop DmMonitorServiceconfirm
关闭主库守护进程：systemctl stop DmWatcherServiceDMSVR02
关闭备库守护进程：systemctl stop DmWatcherServiceDMSVR01
关闭主库实例：systemctl stop DmServiceDMSVR01
关闭备库实例：systemctl stop DmServiceDMSVR02
