我会在EC2上用5分钟搭建WordPress。
按照以下步骤进行创建。

启动WordPress

※我们将省略启动EC2。
※我们将使用Amazon Linux作为AMI。

安装Docker

在yum里快速安装


       __|  __|_  )
       _|  (     /   Amazon Linux AMI
      ___|\___|___|

https://aws.amazon.com/amazon-linux-ami/2016.09-release-notes/
$ sudo su
# yum install -y docker

安装Docker Compose

按照公式参考进行安装

# curl -L "https://github.com/docker/compose/releases/download/1.8.1/docker-compose-$(uname -s)-$(uname -m)" > /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   600    0   600    0     0    684      0 --:--:-- --:--:-- --:--:--   684
100 7798k  100 7798k    0     0   636k      0  0:00:12  0:00:12 --:--:-- 1132k
# chmod +x /usr/local/bin/docker-compose
# /usr/local/bin/docker-compose -v
docker-compose version 1.8.1, build 878cff1

创建启动文件

根据公式创建启动文件（docker-compose.yml）。

# cat <<EOF > docker-compose.yml
version: '2'

services:
   db:
     image: mysql:5.7
     volumes:
       - "./.data/db:/var/lib/mysql"
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: wordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     links:
       - db
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_PASSWORD: wordpress
EOF

启动WordPress

启动Docker服务器

# service docker start
Starting cgconfig service:                                 [  OK  ]
Starting docker:    .                                  [  OK  ]

启动WordPress

# /usr/local/bin/docker-compose up -d
