关于Linux系统中注册DM相关服务，环境Linux7，DM8?
注册服务：./dm_service_installer.sh
注销服务：./dm_service_uninstaller.sh
该shell文件在DM安装目录的script/root下(我的安装目录为/home/dmdba/dmdbs)
注册和注销服务需要以root身份登录
./dm_service_installer.sh -h 查看命令格式
cd /home/dmdba/dmdbms/script/root/
[root@test01 root]# ./dm_service_installer.sh -h
Usage: dm_service_installer.sh -t service_type [-p service_name_postfix] [-dm_ini dm_ini_file]
? ? ? ? [-watcher_ini watcher_ini_file ] [-monitor_ini monitor_ini_file] [-cssm_ini cssm_ini_file]
? ? ? ? [-dfs_ini dfs_ini_file] [-dcr_ini dcr_ini_file]
? ? ? ? [-dss_ini dss_ini_file] [-drs_ini drs_ini_file] [-dras_ini dras_ini_file] [-dcs_ini dcs_ini_file] [-server server_info]
? ? ? ? [-dmap_ini dmap_ini_file] [-m open|mount] [-y dependent_service] [-auto true|false]
? or dm_service_installer.sh [-s service_file_path]
? or dm_service_installer.sh -h
? ?-t ? ? ? ? ? ? ? 服务类型,包括dmimon,dmap,dmserver,dmwatcher,dmmonitor,dmcss,dmcssm,dmasmsvr,dmdcs,dmdrs,dmdras,dmdss
? ?-p ? ? ? ? ? ? ? 服务名后缀,对于dmimon,dmap服务类型无效，生成的操作系统服务名为“服务脚本模 板名称+服务名后缀”
? ?-dm_ini ? ? ? ? ?dm.ini文件路径
? ?-watcher_ini ? ? dmwatcher.ini文件路径.
? ?-monitor_ini ? ? dmmonitor.ini文件路径.
? ?-dcr_ini ? ? ? ? dmdcr.ini文件路径.
? ?-cssm_ini ? ? ? ?dmcssm.ini文件路径.
? ?-dss_ini ? ? ? ? dss.ini文件路径.
? ?-drs_ini ? ? ? ? drs.ini文件路径.
? ?-dras_ini ? ? ? ?dras.ini文件路径.
? ?-dcs_ini ? ? ? ? dcs.ini文件路径.
? ?-dfs_ini ? ? ? ? dfs.ini文件路径.
? ?-dmap_ini ? ? ? ?dmap.ini文件路径.
? ?-server ? ? ? ? ?服务器信息(IP:PORT)
? ?-auto ? ? ? ? ? ?设置服务是否自动启动,值为true或false，默认true.
? ?-m ? ? ? ? ? ? ? 设置服务器启动模式open或mount,只针对dmserver服务类型生效,可选
? ?-y ? ? ? ? ? ? ? 设置依赖服务，此选项只针对systemd服务环境下的dmserver和dmasmsvr服务生效
? ?-s ? ? ? ? ? ? ? 服务脚本路径，设置则忽略除-y外的其他参数选项
? ?-h ? ? ? ? ? ? ? 帮助以dmserver服务为例：
如果输入/home/dmdba/dmdbs/bin/dmserver命令启动dmserver如图所示，窗口无法结束，结束窗口则服务也会关闭

DM Database Server shutdown successfully.?为了方便用户能够使DM服务程序以后台运行的方式启动，DM 服务程序提供了对应的服务脚本模板
注册服务：
./dm_service_installer.sh -t dmserver -dm_ini /dmdata/DAMENG/dm.ini -p GRP1_RT_01
通过服务脚本文件注册服务 ：
如果已存在修改完成的服务脚本模板。用户可通过此服务脚本文件注册操作系统随机启动服务。
./dm_service_installer.sh -s /home/dmdba/dmdbms/bin/DmServiceGRP1_RT_01
如图生成一个DmServiceGRP1_RT_01.service服务 服务脚本路径为安装目录的bin目录下(我的为/home/dmdba/dmdbs/bin)
# cd /home/dmdba/dmdbms/script/root/
[root@test01 root]# ./dm_service_installer.sh -t dmserver -dm_ini /dmdata/DAMENG/dm.ini -p GRP1_RT_01
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServiceGRP1_RT_01.service to /usr/lib/systemd/system/DmServiceGRP1_RT_01.service.
创建服务(DmServiceGRP1_RT_01)完成服务脚本支持的命令：
start|stop|status|condrestart|restart。
如下：
cd /home/dmdba/dmdbms/bin
start启动服务：
./DmServiceGRP1_RT_01 start
stop停止服务：
./DmServiceGRP1_RT_01 stop
restart 重启服务命令：
/DmServiceGRP1_RT_01 restart #重启服务
condrestart condrestart 也属于重启命令，但增加了确认条件。如果服务正在运行，等同于 restart 命令。
如果服务没有在运行，打印消息如下： DmServiceGRP1_RT_01 service is not running.
status查看服务状态：stopped表示已停止
注销服务：
./dm_service_uninstaller.sh -n?DmServiceGRP1_RT_01 #注销服务DmServiceGRP1_RT_01
