前提需要声明版本
这里容器的连接是双向的
yum install docker-compose -y
[root@master wordpress]# cat docker-compose.yml
version: '3'
services:
db:
image: mysql:5.7
volumes:
- /data/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
volumes:
- /data/web_data:/var/www/html
ports:
- "80:80"
restart: always
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
docker-compose up -d #启动服务
docker-compose restart db或wordpress(服务名称)
服务之间通过dns解析
root@a7fad202cb7a:/var/www/html# cat /etc/resolv.conf
nameserver 127.0.0.11
