【WordPress】使用 Docker 创建 WordPress 实例

Posted by 西维蜀黍 on 2020-05-05, Last Modified on 2021-09-21

Create docker-compose.yml

Change into your project directory.

For example, if you named your directory my_wordpress:

cd my_wordpress/

Create a docker-compose.yml file that starts your WordPress blog and a separate MySQL instance with a volume mount for data persistence:

version: "3.9"
    
services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: somewordpress
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress
    
  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "8000:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
      WORDPRESS_DB_NAME: wordpress
volumes:
  db_data: {}

Build the project

Now, run docker-compose up -d from your project directory.

This runs docker-compose up in detached mode, pulls the needed Docker images, and starts the wordpress and database containers, as shown in the example below.

如果 docker-compose 没有安装（出现下面错误），可以通过下面方式进行安装：

$ docker-compose up -d
command not found: docker-compose

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
 
$ sudo chmod +x /usr/local/bin/docker-compose

$ docker-compose up -d

If you are using Docker Desktop for Mac or Docker Desktop for Windows, you can use http://localhost as the IP address, and open http://localhost:8000 in a web browser.

Shutdown and cleanup

The command docker-compose down removes the containers and default network, but preserves your WordPress database.

The command docker-compose down --volumes removes the containers, default network, and the WordPress database.
