使用docker虚拟化技术，lamp架构，搭建wordpress博客服务

使用平台

Ubuntu 16.04.1 LTS (GNU/Linux 4.4.0-91-generic x86_64)

搭建思路步骤

需求：使用wprdpress搭建一个私人博客，并且将服务仍到docker容器中

1.构建wordpress的docker容器

2.在容器中搭建lamp架构

3.在lamp架构上，配置wordpress

4.测试运行

5.导出wordpress镜像

构建wordpress的docker容器

1.远程登陆阿里云服务

[root@localhost zip]# ssh root@118.24.176.175 root@118.24.176.175's password: Welcome to Ubuntu 16.04.1 LTS (GNU/Linux 4.4.0-91-generic x86_64) ​ * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage ​ Last login: Sun May 27 04:40:30 2018 from 113.133.193.164
[root@localhost zip]# ssh root@118.24.176.175 root@118.24.176.175's password: Welcome to Ubuntu 16.04.1 LTS (GNU/Linux 4.4.0-91-generic x86_64) ​ * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage ​ Last login: Sun May 27 04:40:30 2018 from 113.133.193.164
[root@localhost zip]# ssh root@118.24.176.175 root@118.24.176.175's password: Welcome to Ubuntu 16.04.1 LTS (GNU/Linux 4.4.0-91-generic x86_64) ​ * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage ​ Last login: Sun May 27 04:40:30 2018 from 113.133.193.164

2.在mnt目录下，已经准备好了wordpress安装包和一个ubuntu的docker镜像

root@VM-0-16-ubuntu:~# cd /mnt/ root@VM-0-16-ubuntu:/mnt# ls ubuntu.tar wordpress-4.9.4-zh_CN.zip
root@VM-0-16-ubuntu:~# cd /mnt/ root@VM-0-16-ubuntu:/mnt# ls ubuntu.tar wordpress-4.9.4-zh_CN.zip
root@VM-0-16-ubuntu:~# cd /mnt/ root@VM-0-16-ubuntu:/mnt# ls ubuntu.tar wordpress-4.9.4-zh_CN.zip

wordpress包可以在官网下载，ubuntu的docker镜像可以使用docker pull ubuntu获取

3.使用apt-get命令下载并安装docker的服务端和客户端，安装完成，启动docker守护进程

root@VM-0-16-ubuntu:/mnt# apt-get install docker* Reading package lists... Done Building dependency tree Reading state information... Done ...下载docker过程 root@VM-0-16-ubuntu:/mnt# systemctl start docker
root@VM-0-16-ubuntu:/mnt# apt-get install docker* Reading package lists... Done Building dependency tree Reading state information... Done ...下载docker过程 root@VM-0-16-ubuntu:/mnt# systemctl start docker
root@VM-0-16-ubuntu:/mnt# apt-get install docker* Reading package lists... Done Building dependency tree Reading state information... Done ...下载docker过程 root@VM-0-16-ubuntu:/mnt# systemctl start docker

4.导入原始的ubuntu镜像

root@VM-0-16-ubuntu:/mnt# docker load --input ubuntu.tar 454970bd163b: Loading layer [==================================================>] 196.8 MB/196.8 MB 38112156678d: Loading layer [==================================================>] 208.9 kB/208.9 kB 4e1f7c524148: Loading layer [==================================================>] 4.608 kB/4.608 kB 56063ad57855: Loading layer [==================================================>] 1.024 kB/1.024 kB
root@VM-0-16-ubuntu:/mnt# docker load --input ubuntu.tar 454970bd163b: Loading layer [==================================================>] 196.8 MB/196.8 MB 38112156678d: Loading layer [==================================================>] 208.9 kB/208.9 kB 4e1f7c524148: Loading layer [==================================================>] 4.608 kB/4.608 kB 56063ad57855: Loading layer [==================================================>] 1.024 kB/1.024 kB
root@VM-0-16-ubuntu:/mnt# docker load --input ubuntu.tar 454970bd163b: Loading layer [==================================================>] 196.8 MB/196.8 MB 38112156678d: Loading layer [==================================================>] 208.9 kB/208.9 kB 4e1f7c524148: Loading layer [==================================================>] 4.608 kB/4.608 kB 56063ad57855: Loading layer [==================================================>] 1.024 kB/1.024 kB

5.以ubuntu的镜像为基础镜像，构建名为wordpress的docker容器

root@VM-0-16-ubuntu:/mnt# docker run -it -p 80:80 --name wordpress ubuntu /bin/bash
root@VM-0-16-ubuntu:/mnt# docker run -it -p 80:80 --name wordpress ubuntu /bin/bash
root@VM-0-16-ubuntu:/mnt# docker run -it -p 80:80 --name wordpress ubuntu /bin/bash

这里将宿主机的80端口映射到容器的80端口

搭建lamp平台架构思路：

所有的步骤都是在容器内完成

1.进入wordpress容器

root@VM-0-16-ubuntu:/mnt#docker start -i wordpress root@441efb1ccb8e:
root@VM-0-16-ubuntu:/mnt#docker start -i wordpress root@441efb1ccb8e:
root@VM-0-16-ubuntu:/mnt#docker start -i wordpress root@441efb1ccb8e:

2.安装apache服务

root@441efb1ccb8e:/# apt-get install apache2 Reading package lists... Done Building dependency tree Reading state information... Done ...下载apache过程 
root@441efb1ccb8e:/# apt-get install apache2 Reading package lists... Done Building dependency tree Reading state information... Done ...下载apache过程 
root@441efb1ccb8e:/# apt-get install apache2 Reading package lists... Done Building dependency tree Reading state information... Done ...下载apache过程 

3.下载安装php5

root@441efb1ccb8e:/# apt-get install php5 Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程
root@441efb1ccb8e:/# apt-get install php5 Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程
root@441efb1ccb8e:/# apt-get install php5 Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程

4.下载安装mysql服务端和客户端

安装过程中，会提示输入mysql密码

root@441efb1ccb8e:/# apt-get install mysql-server Reading package lists... Done Building dependency tree Reading state information... Done ​ root@441efb1ccb8e:/# apt-get install mysql-client Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程
root@441efb1ccb8e:/# apt-get install mysql-server Reading package lists... Done Building dependency tree Reading state information... Done ​ root@441efb1ccb8e:/# apt-get install mysql-client Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程
root@441efb1ccb8e:/# apt-get install mysql-server Reading package lists... Done Building dependency tree Reading state information... Done ​ root@441efb1ccb8e:/# apt-get install mysql-client Reading package lists... Done Building dependency tree Reading state information... Done 。。。安装过程

5.安装php5-mysql

该组建连接php5和mysql

root@441efb1ccb8e:/# apt-get install php5-mysql Reading package lists... Done Building dependency tree Reading state information... Done
root@441efb1ccb8e:/# apt-get install php5-mysql Reading package lists... Done Building dependency tree Reading state information... Done
root@441efb1ccb8e:/# apt-get install php5-mysql Reading package lists... Done Building dependency tree Reading state information... Done

6.启动lamp架构

root@441efb1ccb8e:/# /etc/init.d/apache2 start root@441efb1ccb8e:/# /etc/init.d/mysql start
root@441efb1ccb8e:/# /etc/init.d/apache2 start root@441efb1ccb8e:/# /etc/init.d/mysql start
root@441efb1ccb8e:/# /etc/init.d/apache2 start root@441efb1ccb8e:/# /etc/init.d/mysql start

这时可以进行测试apache服务和php是否安装成功：

在/var/www/html/目录下编辑一个名为index.php的文件 使用curl localhost/index.php访问，如果返回编辑内容，则证明成功

7.在mysql中，建立一个名为wordpress的库

root@441efb1ccb8e:/# mysql -uroot -p 键入密码 mysql> CREATE DATABASE wordpress; Query OK, 1 row affected (0.00 sec)
root@441efb1ccb8e:/# mysql -uroot -p 键入密码 mysql> CREATE DATABASE wordpress; Query OK, 1 row affected (0.00 sec)
root@441efb1ccb8e:/# mysql -uroot -p 键入密码 mysql> CREATE DATABASE wordpress; Query OK, 1 row affected (0.00 sec)

给wordpress安装lftp客户端，方便从宿主机上获取wordpress安装包

root@441efb1ccb8e:/mnt# apt-get install lftp Reading package lists... Done Building dependency tree Reading state information... Done 。。。下载过程
root@441efb1ccb8e:/mnt# apt-get install lftp Reading package lists... Done Building dependency tree Reading state information... Done 。。。下载过程
root@441efb1ccb8e:/mnt# apt-get install lftp Reading package lists... Done Building dependency tree Reading state information... Done 。。。下载过程

将宿主机的wordpress安装包放在vsftpd服务的发布目录

这里直接解压好，并且修改了其中一个配置文件

root@VM-0-16-ubuntu:/var/ftp/pub# ls wordpress root@VM-0-16-ubuntu:/var/ftp/pub# pwd /var/ftp/pub
root@VM-0-16-ubuntu:/var/ftp/pub# ls wordpress root@VM-0-16-ubuntu:/var/ftp/pub# pwd /var/ftp/pub
root@VM-0-16-ubuntu:/var/ftp/pub# ls wordpress root@VM-0-16-ubuntu:/var/ftp/pub# pwd /var/ftp/pub

将wordpress目录中wp-config-sample.php重命名为wp-config.php

root@VM-0-16-ubuntu:/var/ftp/pub# cp wordpress/wp-config-sample.php wordpress/wp-config.php
root@VM-0-16-ubuntu:/var/ftp/pub# cp wordpress/wp-config-sample.php wordpress/wp-config.php
root@VM-0-16-ubuntu:/var/ftp/pub# cp wordpress/wp-config-sample.php wordpress/wp-config.php

修改wp-config.php文件，里面是连接mysql的相关信息，要更改为自己的mysql相关信息

该文件主要提供数据库的名字(如这里的wordpress)，用户名(如root)，密码(如安装mysql时键入的密码)
该文件主要提供数据库的名字(如这里的wordpress)，用户名(如root)，密码(如安装mysql时键入的密码)
该文件主要提供数据库的名字(如这里的wordpress)，用户名(如root)，密码(如安装mysql时键入的密码)

使用wordpress容器获取宿主机的wordpress目录

root@441efb1ccb8e:/var/www/html# lftp 172.17.0.1 lftp 172.17.0.1:~> ls drwxr-xr-x 5 0 0 4096 May 28 11:44 wordpress lftp 172.17.0.1:/> mirror wordpress/ Total: 143 directories, 1528 files, 0 symlinks New: 1528 files, 0 symlinks 28179250 bytes transferred in 3 seconds (9.09M/s) lftp 172.17.0.1:/> exit root@441efb1ccb8e:/var/www/html# ls index.html wordpress
root@441efb1ccb8e:/var/www/html# lftp 172.17.0.1 lftp 172.17.0.1:~> ls drwxr-xr-x 5 0 0 4096 May 28 11:44 wordpress lftp 172.17.0.1:/> mirror wordpress/ Total: 143 directories, 1528 files, 0 symlinks New: 1528 files, 0 symlinks 28179250 bytes transferred in 3 seconds (9.09M/s) lftp 172.17.0.1:/> exit root@441efb1ccb8e:/var/www/html# ls index.html wordpress
root@441efb1ccb8e:/var/www/html# lftp 172.17.0.1 lftp 172.17.0.1:~> ls drwxr-xr-x 5 0 0 4096 May 28 11:44 wordpress lftp 172.17.0.1:/> mirror wordpress/ Total: 143 directories, 1528 files, 0 symlinks New: 1528 files, 0 symlinks 28179250 bytes transferred in 3 seconds (9.09M/s) lftp 172.17.0.1:/> exit root@441efb1ccb8e:/var/www/html# ls index.html wordpress

这里修给了index.html，方便使用浏览器访问宿主机IP跳转到wordpress

root@441efb1ccb8e:/var/www/html#echo "<a href="wordpress">my wordpress</a>" > index.html
root@441efb1ccb8e:/var/www/html#echo "<a href="wordpress">my wordpress</a>" > index.html
root@441efb1ccb8e:/var/www/html#echo "<a href="wordpress">my wordpress</a>" > index.html

到这里，一个新的wordpress已经搭建成功

构建好的wordpress容器，可以将其导出为镜像，在其他平台上直接使用

root@VM-0-16-ubuntu:~# docker commit -a 'qpy' -m 'wordpress' wordpress qpy/wordpress sha256:62607c25506d873c3b07e0096b3bdcf16b8cb97895f366969158c0cc5c85aae4 root@VM-0-16-ubuntu:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE qpy/wordpress latest 62607c25506d 6 seconds ago 379 MB ubuntu latest 07c86167cdc4 2 years ago 188 MB
