记一次 Docker 容器启动失败

情况是一台虚拟机上的达梦数据库连不上了，实际上也无法通过 SSH 连上虚拟机，尝试通过 VMWare 控制台重启服务器。

重启后，机器还是无法连接，扩大磁盘重启，勉强能连，但是很卡。后来这个事暂时搁置了。

到今天一看，机器能连了，而且很顺畅，尝试重启达梦数据库。结果失败：

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE                                   COMMAND             CREATED             STATUS                    PORTS                    NAMES

[root@localhost ~]# docker start 4311f58856b7
Error response from daemon: oci runtime error: container_linux.go:300: starting container process caused "process_linux.go:255: applying cgroup configuration for process caused \"Failed to activate service 'org.freedesktop.systemd1': timed out\""
Error: failed to start containers: 4311f58856b7

似乎一些服务没有启动起来，导致容器启动失败。重启 docker 试试，结果发现停止 docker 后无法正常启动：

[root@localhost ~]# systemctl stop docker
Authorization not available. Check if polkit service is running or see debug message for more information.
[root@localhost ~]# systemctl start docker
Authorization not available. Check if polkit service is running or see debug message for more information.
Failed to start docker.service: 连接超时
See system logs and 'systemctl status docker.service' for details.

网上说可能是 polkit 服务没有启动，确实是没有启：

[root@localhost ~]# systemctl status polkit
● polkit.service - Authorization Manager
   Loaded: loaded (/usr/lib/systemd/system/polkit.service; static; vendor preset: enabled)
   Active: failed (Result: timeout) since 四 2025-03-27 19:44:55 CST; 3 days ago
     Docs: man:polkit(8)

3 月 27 19:44:55 localhost.localdomain systemd[1]: polkit.service failed.

尝试重启 polkit 服务，结果也没有启动起来：

[root@localhost ~]# systemctl start polkit
Authorization not available. Check if polkit service is running or see debug message for more information.
Failed to start polkit.service: 连接超时
See system logs and 'systemctl status polkit.service' for details.

最后通过reboot命令重启虚拟机，发现 polkit 正常，重启容器成功。
