centos8 Failed to get properties: Access denied
Failed to start docker.service: Access denied
今天在centos8上安装docker,参考以下网址
https://www.cnblogs.com/yufeng218/p/8370670.html
安装完了运行docker info显示错误
Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info
找了N多解决方案,什么daemon.json的、yum update的、systemctl start docker的都白搭,而且运行任何的systemctl命令都被拒绝,显示Failed to start docker.service: Access denied
最后找到个解决方案
https://superuser.com/questions/1125250/systemctl-access-denied-when-root/1130976
In my case, I had just upgraded systemd
and any systemctl
command was failing:
# systemctl daemon-reexec
Failed to reload daemon: Access denied
# systemctl status
Failed to read server status: Access denied
However according to the init
manpage, you can do the same thing by sending SIGTERM
to the daemon running as PID 1, which worked:
kill -TERM 1
This reloaded the daemon, after which all the systemctl
commands started working again.
