docker映射端口与ssh访问或容器访问
映射端口
-d 后台执行
-p映射端口
--privileged 可以使用systemctl
# docker run --privileged -d -p 9000:80 jiqing9006/centos:httpd /sbin/init
e2e33ac1fb2acdef86c995c79eb746fb552417b112210bc5353de74a2f63e4e7
访问容器
root@ThinkPad:/home/jiqing# docker ps -q
e2e33ac1fb2a
root@ThinkPad:/home/jiqing# docker exec -it e2e33ac1fb2a /bin/bash
开启httpd服务
systemctl restart httpd
外部访问
$ sudo netstat -anpl|grep :9000
tcp6 0 0 :::9000 :::* LISTEN 10352/docker-proxy
修改容器密码，默认root的密码是随机的，需要修改一下
[root@e2e33ac1fb2a /]# passwd root
Changing password for user root.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
配置完密码，把22端口映射出去，就可以远程访问了。
安装sshd
[root@e2e33ac1fb2a /]# yum install openssh-server
