临时关闭达梦数据库服务自启使用root执行。
1、先将达梦的服务罗列出
[root@dsc1 ~]# systemctl list-units --type=service|grep Dm
DmAPService.service loaded active running Dameng Assistant Plug-In Service(DmAPService).
DmASMSvrServiceASM.service loaded active running Dameng ASM Server Service(DmASMSvrServiceASM).
DmCSSServiceCSS.service loaded active running Dameng CSS Service(DmCSSServiceCSS).
DmServiceDSC.service loaded active running Dameng Database Service(DmServiceDSC).
2、按照罗列的服务名称去掉服务自启
[root@dsc1 ~]# systemctl disable DmAPService.service
Removed symlink /etc/systemd/system/multi-user.target.wants/DmAPService.service.
[root@dsc1 ~]# systemctl disable DmASMSvrServiceASM.service
Removed symlink /etc/systemd/system/multi-user.target.wants/DmASMSvrServiceASM.service.
[root@dsc1 ~]# systemctl disable DmCSSServiceCSS.service
Removed symlink /etc/systemd/system/multi-user.target.wants/DmCSSServiceCSS.service.
[root@dsc1 ~]# systemctl disable DmServiceDSC.service
Removed symlink /etc/systemd/system/multi-user.target.wants/DmServiceDSC.service.
3、查看服务是否已经变成disable
[root@dsc1 ~]# systemctl list-unit-files|grep Dm
DmAPService.service disable
DmASMSvrServiceASM.service disable
DmCSSServiceCSS.service disable
DmServiceDSC.service disable
