wordpress篇之使用docker安装wordpress

配置服务器

1. 更换源

首先肯定要有一台服务器了，我用的是Ubuntu系统。拿到服务器，先配置一下阿里源。

• 备份原文件

  sudo cp /etc/apt/sources.list /etc/apt/sources_cp.list
  

• 打开配置文件

  sudo vim /etc/apt/sources.list
  

• 将全部内容替换源

  deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
  

• 更新

  sudo apt-get update
  

2. 添加安全规则

• 登录你的服务器管理平台，找到有个类似下面的选项：

• 新建l两个安全组，具体操作参考入方向和出方向

• 添加入方向规则

• 添加出方向规则

安装Docker

• Install Docker CE

  2. sudo apt-get install \
         apt-transport-https \
       ca-certificates \
         curl \
         software-properties-common
     

  3. curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
     

  4. sudo apt-key fingerprint 0EBFCD88
     

  5. sudo add-apt-repository \
        "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
        stable"
     

  6. sudo apt-get update
     

  7. sudo apt-get install docker-ce
     

  8. 测试是否安装成功, 运行一下命令：

     sudo docker run hello-world
     

     会输出 Hello from Docker! 。

• Install Docker Compose

  1. 下载最新版本的 Docker Compose

     sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
     

  2. 开放执行权限

     sudo chmod +x /usr/local/bin/docker-compose
     

  3. 检测是否安装成功

     docker-compose --version
     

  4. 卸载（可选）

     • 按上面步骤安装的卸载方法：

       sudo rm /usr/local/bin/docker-compose
       

     • pip 安装的卸载方法

       pip uninstall docker-compose
       

部署 WordPress

1. 拉取必要文件

   docker pull mysql:5.7
   docker pull wordpress:latest
   

2. 创建目录文件

   mkdir my_wordpress && cd my_wordpress
   

3. 创建 docker-compose.yml 配置文件

   vim docker-compose.yml
   

   version: '3.3'
   
   services:
      db:
        image: mysql:5.7
        volumes:
          - db_data:/var/lib/mysql
        restart: always
        environment:
          MYSQL_ROOT_PASSWORD: somewordpress
          MYSQL_DATABASE: wordpress	# 数据库名
          MYSQL_USER: admin	# 数据库用户名
          MYSQL_PASSWORD: 123	# 数据库密码
   
      wordpress:
        depends_on:
          - db
        image: wordpress:latest
        ports:
          - "8080:80"
        restart: always
        environment:
          WORDPRESS_DB_HOST: db:3306
          WORDPRESS_DB_USER: admin	# 数据库用户名
          WORDPRESS_DB_PASSWORD: 123	# 数据库密码
          WORDPRESS_DB_NAME: wordpress	# 数据库名
   volumes:
       db_data: {}
   

4. 执行并查看后台启动的容器

   docker-compose up -d
   docker-compose ps
   

5. 打开浏览器

   服务器ip:8080
   

6. 简单配置一下登录名和密码, ok
