docker内进行systemctl等命令时，出现错误。

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

docker启动方式需要变化。启动时添加 --privileged=true 和 /sbin/init
后面/bin/bash需要替换为/sbin/init

即由此方式：

 docker run -tid --name test centos  /bin/bash

变更为：

 docker run -tid --name test --privileged=true  centos  /sbin/init

完整参数说明：

 docker run -v /tmp/:/tmp --privileged --cap-add SYS_ADMIN -e container=docker -it --name=centos -d --restart=always centos /usr/sbin/init
