Container Station打开时一直loading。 ssh连上QTS后，也不能通过命令进行docker操作，报错：

Can't connect to docker daemon.

参考了官方文档和论坛里的帖子，尝试了以下操作都不起任何作用：

  • 重启container station
  • 重启所有服务
  • 卸载重装container station
  • 删除虚拟交换机，安装container station
  • 机器重启后重装container station
  • 手动安装container station旧版本
  • 系统固件更新到旧版本，安装container station
  • 系统固件从旧版本更新到新版本，安装container station

继续查找原因。Container Stattion的日志在：/share/CACHEDEV1_DATA/.qpkg/container-station/var/log/container-station，查看日志都挺正常，只在ctstation.log中发现了异常，都是打不开数据库:

既然是数据库文件打不开，就尝试删除数据库文件。首先停止container station，然后重命名ctstation.sqlite为ctstation.sqlite.bak，让系统生成新的文件。重新启用container station。结果还是不工作。

继续查找原因， 根据日志里的路径去查看python代码，发现有些是pyc文件，反编译pyc文件，查看session相关的代码，没有发现有什么问题，觉得是系统内部状态出了问题。

最后不得不重置系统设置来解决问题。 步骤：

  • 在控制台 -> 备份/恢复，备份系统设置
  • 在控制台 -> 备份/恢复 -> 恢复出厂默认设置， 选择重置设置，然后等待系统重启
  • 重启登录后，在控制台 -> 备份/恢复，浏览之前备份的系统设置文件，点击恢复，等待系统恢复设置和安装App

这次container station终于正常工作了。
