我使用以下命令启动了一个docker容器
docker run --name MysqL --restart always -p 3306:3306 -v /var/lib/MysqL:/var/lib/MysqL -e MysqL_ROOT_PASSWORD=password -d MysqL:5.7.14
然后想将wordpress网站与以下docker-compose.yml文件连接起来
version: '2'
services:
wordpress:
image: wordpress
external_links:
- MysqL:MysqL
ports:
- 80:80
environment:
wordpress_DB_USER: root
wordpress_DB_PASSWORD: password
volumes:
- /var/www/somesite.com:/var/www/html
但我不断收到以下错误
Starting somesitecom_wordpress_1
Attaching to somesitecom_wordpress_1
wordpress_1 |
wordpress_1 | Warning: MysqLi::MysqLi(): (HY000/2002): Connection refused in - on line 19
wordpress_1 |
wordpress_1 | MysqL Connection Error: (2002) Connection refused
似乎external_links不起作用.
知道我做错了什么吗？
最佳答案
您的链接正常,但您在Docker内的不同网络上.从docker-compose.yml docs：
Note: If you’re using the version 2 file format,the externally-created containers must be connected to at least one of the same networks as the service which is linking to them.
要解决此问题,您可以创建自己的网络：
docker network create dbnet
docker network connect dbnet MysqL
然后使用以下命令配置docker-compose.yml：
version: '2'
networks:
dbnet:
external:
name: dbnet
services:
wordpress:
image: wordpress
ports:
- 80:80
environment:
wordpress_DB_USER: root
wordpress_DB_PASSWORD: password
volumes:
- /var/www/somesite.com:/var/www/html
networks:
- dbnet
