即使作为 root 用户，也无法在 Centos 7 中启动服务并出现错误“授权不可用”

  • 772

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)
 Docs: https://docs.docker.com

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
      Docs: man:polkit(8)
   Process: 7932 ExecStart=/usr/lib/polkit-1/polkitd --no-debug (code=killed, signal=TERM)
  Main PID: 7932 (code=killed, signal=TERM)

  Feb 04 11:14:54 myserver.com systemd[1]: Unit polkit.service entered failed state.
  Feb 04 11:14:54 myserver.com systemd[1]: polkit.service failed.

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？

centos service centos7 docker authorization

  1. Best Answer

    我发了一个

    [root@myserver home]# reboot

    命令，它似乎正在工作。之前，当我遇到最初的问题时，我使用过

    [root@myserver home]# shutdown -r now

    我很好奇为什么这两个命令的差异导致了我最初的问题......

  2. 只是记录我的情况，这可以帮助一些人

    polkit 是一种策略服务，这意味着其他一些服务在执行操作之前需要它的授权

    如果我尝试启动或重新启动任何服务（如网络或 sshd）在 kvm 备份还原来宾 VM 使用 centos 7 后出现问题，系统会在显示此消息几秒钟后重新启动

    Authorization not available. Check if polkit service is running or see debug message for more information.

    就我而言，polkit 抱怨 dbus 错误，例如

    Failed to connect to system bus: Connection refused

    journalctl -b -p 错误

    我发现 dbus 缺少磁盘原因问题

    解决方案很容易从 fstab 中删除丢失的磁盘
