达梦数据库 DM8 中 注册服务 说明

在之前的博客我们了解了DM7中的服务注册，如下：

在DM8中，注册服务命令的使用有所变化。

我们先看帮助：

[dmdba@dm8 root]$ pwd
/dm/dmdbms/script/root
[dmdba@dm8 root]$ ./dm_service_installer.sh -h
Must run the script by root!
[dmdba@dm8 root]$ exit
logout
[root@www.cndba.cn system]# cd /dm/dmdbms/script/root
[root@www.cndba.cn root]# ./dm_service_installer.sh -h
Usage: dm_service_installer.sh -t service_type [-p service_name_postfix] [-dm_ini dm_ini_file]

脚本中参数部分变化比较明显，不同的类型有独立的参数对应。 在注册时对应上就好。我们这里注册一个DM8的单实例：

注册：

[root@www.cndba.cn root]# ./dm_service_installer.sh -t dmserver -p dave -dm_ini /dm/dmdbms/data/dave/dm.ini 
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServicedave.service to /usr/lib/systemd/system/DmServicedave.service.
Finished to create the service (DmServicedave)
[root@www.cndba.cn root]# 
[root@www.cndba.cn root]# systemctl start DmServicedave.service 
[root@www.cndba.cn log]# ps -ef|grep dm.ini
dmdba     7501     1  0 13:55 ?        00:00:00 /dm/dmdbms/bin/dmserver /dm/dmdbms/data/dave/dm.ini -noconsole
root      7587  5538  0 13:57 pts/4    00:00:00 grep --color=auto dm.ini
[root@www.cndba.cn log]#

卸载：

[root@www.cndba.cn root]# ./dm_service_uninstaller.sh -n DmServicedave
Whether to delete the service(DmServicedave) (Y/y:yes N/n:no): y
Failed to stop DmServicedave.service: Unit DmServicedave.service not loaded.
Failed to execute operation: Bad message
Finished to delete the service file(/usr/lib/systemd/system/DmServicedave.service)
Finished to delete the service(DmServicedave)

如果是其他服务，只需要通过-t和对应的 -xx_ini 来指定信息即可。
