我无法为以下 Centos 7 服务器启动服务
[root@myserver home]# uname -r
3.10.0-1160.11.1.el7.x86_64
[root@myserver home]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)
当我观察到 docker 宕机时，我第一次意识到有问题，所以我以 root 身份运行以下命令
[root@myserver home]# systemctl start docker
Authorization not available. Check if polkit service is running or see debug message for
more information.
Failed to start docker.service: Connection timed out
See system logs and 'systemctl status docker.service' for details.
[root@myserver home]# systemctl status docker.service
● docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
Active: inactive (dead)

然后我跑了
[root@myserver home]# systemctl | grep -i fail
● firewalld.service loaded failed failed firewalld - dynamic firewall daemon
● plymouth-start.service loaded failed failed Show Plymouth Boot Screen
● polkit.service loaded failed failed Authorization Manager
● systemd-machined.service loaded failed failed Virtual Machine and Container Registration Service
● tuned.service loaded failed failed Dynamic System Tuning Daemon
还
[root@myserver home]# systemctl status polkit.service
● polkit.service - Authorization Manager
Loaded: loaded (/usr/lib/systemd/system/polkit.service; static; vendor preset: enabled)
Active: failed (Result: timeout) since Thu 2021-02-04 11:14:54 GMT; 5h 45min ago

我不知道对服务器进行的任何更新。我认为这些问题是在计划外重启后开始的，但我无法确定重启的原因。为什么启动授权管理器会超时？有人对进一步调查有什么建议吗？
