docker创建centos镜像无法使用systemctl

docker获取centos镜像，里面执行安装lnmp之后 发现使用systemctl无法使用

[root@92926bd84d70 /]# systemctl restart nginx
Failed to get D-Bus connection: Operation not permitted

解决办法

1： docker stop 92926bd84d70
2： docker export 92926bd84d70 > centos_lnmp_laster.tar
3：cat centos_lnmp_laster.tar | docker import - centos_lnmp
4: docker run --privileged -itd -p 8088:80 -p 33006:3306 c5062bdb9131 /usr/sbin/init

docker ps -a查看启动镜像

root@centos-mysql01:/data# docker ps -a

docker exec登陆

root@centos-mysql01:/data# docker exec -it 1850715a5140 /bin/bash
[root@1850715a5140 /]# systemctl restart nginx
