在docker中启动服务报错：New main PID 558 does not belong to service

Posted 2022-09-01 为何一再沦落

在docker中启动服务报错： New main PID 558 does not belong to service, and PID file is not owned by root. Refusing.

类似主要错误如下所示：

Job for mongod.service failed because a timeout was exceeded.
See "systemctl status mongod.service" and "journalctl -xe" for details.

使用docker搭建服务环境，拉取了一个Centos7镜像，在镜像中使用 systemctl命令启动 sladpd服务，已经使用 --privileged=true启用特权模式，但还是报错。

解决方法：
挂载宿主机 cgroup目录，启动时加上 -v /sys/fs/cgroup:/sys/fs/cgroup

在docker中使用yum安装mysql后，启动MySQL卡住：

^C
[root@lhrc76mysql soft]# systemctl status mysqld

解决：

挂载宿主机 cgroup 目录，启动时加上 -v /sys/fs/cgroup:/sys/fs/cgroup

docker rm -f centos_1

docker run -d --name centos_1  \\
-p 3306-3406:3306-3406 -p 222:22 \\
-v /sys/fs/cgroup:/sys/fs/cgroup \\
--privileged=true \\
ycj520/centos /usr/sbin/init

docker exec -it centos_1 bash
