3.镜像
在创建镜像时，我们不能关闭容器，必须使其处于运行状态，所以我们必须要另起一个终端，然后执行
[root@yyx1 ~]# docker ps //查看运行中的镜像
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
dcdcbef5e022 centos "/sbin/init" 45 minutes ago Up 45 minutes web
[root@yyx1 ~]# docker commit -p web //生成镜像

4.过程中可能会遇到的问题
[root@0d5c2fb679ae /]# systemctl
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
原因:没有初始化系统
解决方法:保存当前镜像,再用这个镜像新建一个容器
使用这个命令 docker run -d --name 名字 --privileged=true centos /sbin/init 就行了
[root@0d5c2fb679ae /]# apachectl start
AH00112: Warning: DocumentRoot [/usr/local/apache/docs/dummy-host2.example.com] does not exist
原因:配置文件有误
解决方法:进入提示路径 把多余的配置内容删掉
