使用Docker Compose 部署 WordPress

# 1.定义项目，切换到该项目目录
# Compose项目目录：可根据需要命名，是应用程序镜像的上下文环境，仅包含用于构建镜像的资源。
[root@hecs-hqs-01 ~]# mkdir my_wordpress && cd my_wordpress
[root@hecs-hqs-01 my_wordpress]#

# 2.创建并编辑docker-compose.yml 的compose文件来定义项目
# db定义的是mysql服务器，wordpress定义了wordpress博客项目，db_data卷用于保存提交到数据库的数据
[root@hecs-hqs-01 my_wordpress]# vi 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
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: {}

# 3.项目目录中执行docker-compose命令构建项目
[root@hecs-hqs-01 my_wordpress]# docker-compose up -d
