# 操作环境 #

Centos 7

Docker version 17.03.0-ce, build 3a232c8

# 操作步骤 #

1.启动Centos6的Container

[root@localhost ~]# docker images
    REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
    centos6-httpd-new    latest              8f49b55376bb        7 minutes ago       311 MB
    centos6              ssh                 98dd9dcf78e4        About an hour ago   325 MB
    centos6-mysqld       latest              02d4792b8784        2 days ago          396 MB
    centos6-httpd        latest              4a267ee811d7        2 days ago          311 MB
    centos               centos6             ae5cb7280ec3        8 days ago          195 MB
    centos               latest              98d35105a391        8 days ago          192 MB
    registry             latest              047218491f8c        2 weeks ago         33.2 MB
    alpine               latest              4a415e366388        2 weeks ago         3.98 MB
    ubuntu               latest              0ef2e08ed3fa        3 weeks ago         130 MB
    hello-world          latest              48b5124b2768        2 months ago        1.84 kB
    shipyard/shipyard    latest              36fb3dc0907d        5 months ago        58.8 MB
    shipyard/rethinkdb   latest              4841f0ad4547        21 months ago       296 MB
    [root@localhost ~]# docker run -ti ae5cb7280ec3 /bin/bash

2.在Container中安装openssh

[root@c4a48484cdea /]# yum -y install openssh-server openssh-clients

3.修改sshd\_config配置文件中的PermitRootLogin参数，允许root登录ssh

#LoginGraceTime 2m
    PermitRootLogin yes
    #StrictModes yes
    #MaxAuthTries 6
    #MaxSessions 10
    /PermitRootLogin

设置root登录密码

[root@c4a48484cdea /]# passwd 
    Changing password for user root.
    New password: 
    BAD PASSWORD: it is based on a dictionary word
    BAD PASSWORD: is too simple
    Retype new password: 
    passwd: all authentication tokens updated successfully.

4.安装nginx

[root@c4a48484cdea /]#yum -y install nginx

5.安装mysql

[root@c4a48484cdea /]#yum -y install mysql-server

6.制作包含ssh-server、mysql-server、nginx的image

[root@localhost ~]# docker commit c4a48484cdea centos6-ssh-nginx-mysql
    sha256:9c3ac4d67e85108a22bf73597e5afaf2b8d0b1da1b0653c4a49b4f92784e32a5
    [root@localhost ~]# docker images
    REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
    centos6-ssh-nginx-mysql   latest              9c3ac4d67e85        17 seconds ago      1.08 GB
    centos6-httpd-new         latest              8f49b55376bb        20 minutes ago      311 MB
    centos6                   ssh                 98dd9dcf78e4        About an hour ago   325 MB
    centos6-mysqld            latest              02d4792b8784        2 days ago          396 MB
    centos6-httpd             latest              4a267ee811d7        2 days ago          311 MB
    centos                    centos6             ae5cb7280ec3        8 days ago          195 MB
    centos                    latest              98d35105a391        8 days ago          192 MB
    registry                  latest              047218491f8c        2 weeks ago         33.2 MB
    alpine                    latest              4a415e366388        2 weeks ago         3.98 MB
    ubuntu                    latest              0ef2e08ed3fa        3 weeks ago         130 MB
    hello-world               latest              48b5124b2768        2 months ago        1.84 kB
    shipyard/shipyard         latest              36fb3dc0907d        5 months ago        58.8 MB
    shipyard/rethinkdb        latest              4841f0ad4547        21 months ago       296 MB

7.启动Container

[root@localhost ~]# docker run  -ti -p 2201:22 -p 80:80 -p 3336:3306 45098a3e29fd  /bin/bash
    [root@bafd6bc07e28 /]# /etc/init.d/sshd start
    Starting sshd:                                             [  OK  ]
    [root@bafd6bc07e28 /]# /etc/init.d/nginx start
    Starting nginx:                                            [  OK  ]
    [root@bafd6bc07e28 /]# /etc/init.d/mysqld start
    Starting mysqld:                                           [  OK  ]

8.验证ssh server，在宿主机通过ssh登录

[root@localhost ~]# ssh root@localhost -p 2201
    The authenticity of host '[localhost]:2201 ([::1]:2201)' can't be established.
    RSA key fingerprint is 0e:8c:a1:62:b7:00:80:f0:f8:52:4e:95:f9:49:7a:a6.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '[localhost]:2201' (RSA) to the list of known hosts.
    root@localhost's password: 
    [root@bafd6bc07e28 ~]#

9.验证nginx

![Center][]

10.验证mysql
