Centos
即使作為 root 使用者,也無法在 Centos 7 中啟動服務並出現錯誤“授權不可用”
我無法為以下 Centos 7 伺服器啟動服務
[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)
當我觀察到 docker 宕機時,我第一次意識到有問題,所以我以 root 身份執行以下命令
[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
然後我跑了
[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
還
[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 11:13:23 myserver.com systemd[1]: Starting Authorization Manager...

我不知道對伺服器進行的任何更新。我認為這些問題是在計劃外重啟後開始的,但我無法確定重啟的原因。為什麼啟動授權管理器會超時?有人對進一步調查有什麼建議嗎?
我發了一個
[root@myserver home]# reboot
命令,它似乎正在工作。之前,當我遇到最初的問題時,我使用過
[root@myserver home]# shutdown -r now
我很好奇為什麼這兩個命令的差異導致了我最初的問題……
只是記錄我的情況,這可以幫助一些人
polkit 是一種策略服務,這意味著其他一些服務在執行操作之前需要它的授權
如果我嘗試啟動或重新啟動網路或 sshd 等任何服務,則在 kvm 備份還原訪客 VM 使用 centos 7 後出現問題,系統在顯示此消息幾秒鐘後重新啟動
Authorization not available. Check if polkit service is running or see debug message for more information.
就我而言,polkit 抱怨 dbus 錯誤,例如
Failed to connect to system bus: Connection refused
journalctl -b -p 錯誤
我發現 dbus 缺少磁碟原因問題
解決方案很容易從 fstab 中刪除失去的磁碟
