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.
前言
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。
docker 启动命令如下：
1 2 | docker run -itd --name=ldap --privileged=true -v \ -p 80:80 -p 389:389 centos:7 /usr/sbin/init12 |

解决方法：
挂载宿主机 cgroup目录，启动时加上 -v /sys/fs/cgroup:/sys/fs/cgroup
完整启动命令如下：
1 2 3 | docker run -itd --name=ldap --privileged=true \ -v /sys/fs/cgroup:/sys/fs/cgroup \ -p 80:80 -p 389:389 centos:7 /usr/sbin/init |

在docker中使用yum安装MySQL后，启动MySQL卡住：

解决：
挂载宿主机 cgroup 目录，启动时加上 -v /sys/fs/cgroup:/sys/fs/cgroup
1 2 3 4 5 6 7 | docker rm -f lhrc76mysql docker run -d --name lhrc76mysql -h lhrc76mysql \ -p 3306-3406:3306-3406 -p 222:22 \ -v /sys/fs/cgroup:/sys/fs/cgroup \ --privileged=true \ lhrbest/lhrcentos76:5.0 /usr/sbin/init docker exec -it lhrc76mysql bash |
