操作步骤

1. 使用SSH远程工具以dminstalluser帐户登录安装DMServer的主机。
2. 运行如下命令进行卸载。

   source ~/.dmbashrc
   cd $DM_HOME/bin
   python dmserver.py uninstall

   例如（单机模式）：

   [dminstalluser@blrlabvm_171_29 ~]$ cd dmserver/bin
   [dminstalluser@blrlabvm_171_29 bin]$ python dmserver.py uninstall

 说明：

• HA模式下，上述 步骤 必须在主机上执行，但主备机会同时卸载。
• 执行如下命令卸载dmserver和agent：

  python dmserver.py uninstall   --agent-uninstall

  HA模式下，需在主机（处理Web业务和微服务）执行卸载命令（参见步骤2）。如果是备升主场景，则仅在备机执行卸载命令。如果卸载过程中使用了“--agent-uninstall”选项，则从备机进行卸载；否则，可以从任意主备机进行卸载。
