GaussDB-卸载云数据库GaussDB管理平台（TPOPS）
前提条件
如果卸载后需要重装云数据库GaussDB管理平台（TPOPS），请先将所有主机下线。
约束限制
若docker-service目录被删除后需要卸载云数据库GaussDB管理平台（TPOPS），请参照docker-service目录被删除的卸载步骤进行卸载，不需要参照本章节内容。
操作步骤
-
以root用户登录云数据库GaussDB管理平台（TPOPS）任一节点。如需要配置免密卸载，可以参考管理面节点之间互信设置进行配置。
- 操作步骤以/data/docker-service目录为例进行说明，操作时请替换为docker-service所在实际目录。
- 执行节点和远程节点（即除执行节点以外的节点）的目录结构及配置信息需保持一致，否则可能会导致卸载失败。
-
执行以下命令，打开参数配置文件。
vi /data/docker-service/config/user_edit_file.conf
-
修改参数uninstall_all为yes。
"uninstall_all":"yes"
-
按“Esc”键后输入 :wq! 保存并关闭文件。
-
执行以下命令，卸载云数据库GaussDB管理平台（TPOPS）。
cd /data/docker-service
sh appctl.sh uninstall _all
回显如下，说明卸载成功。

执行以下命令，清理残存用户、目录及SFTP数据。
NOTICE:
清理命令会删除SFTP服务器中的所有数据，若SFTP数据仍要使用，请提前备份。
备份方式：将/opt/sftphome/目录下的所有内容复制出来即可。例如：cp -r /opt/sftphome /data/sftphome_bak
sh appctl.sh cleanup_all
回显如下，说明清理成功。
