我创建了一个小的docker-compose.yml,它曾经像魅力一样工作,可以部署小型wordpress实例.它看起来像这样：

wordpress:
  image: wordpress:latest
  links:
   - MysqL
  ports:
   - "1234:80"
  environment:
    wordpress_DB_USER: wordpress
    wordpress_DB_NAME: wordpress
    wordpress_DB_PASSWORD: "password"
    wordpress_DB_HOST: mariadb
    MysqL_PORT_3306_TCP: 3306
  volumes:
    - /srv/wordpress/:/var/www/html/
MysqL:
  image: mariadb:latest
  mem_limit: 256m
  container_name: mariadb
  environment:
    MysqL_ROOT_PASSWORD: "password"
    MysqL_DATABASE: wordpress
    MysqL_USER: wordpress
    MysqL_PASSWORD: "password"
  volumes:
    - /srv/mariadb:/var/lib/MysqL

但是当我现在开始它时(可能是因为docker更新到Docker版本1.9.1,构建a34a1d5),它失败了

wordpress_1 | Warning: MysqLi::MysqLi(): (HY000/2002): Connection    refused in - on line 10
wordpress_1 | 
wordpress_1 | MysqL Connection Error: (2002) Connection refused

当我使用wordpress_1的/ etc / hosts时,有MysqL的条目：

172.17.0.10 MysqL 12a564fdbc56 mariadb

我能够ping MariaDB服务器.

当我使用docker-compose时,会安装wordpress,并在几次重启后打开MariaDB容器：

Version: '10.0.22-MariaDB-1~jessie'  socket: '/var/run/MysqLd/MysqLd.sock'  port: 3306  mariadb.org binary distribution

哪个schould表明它正在运行,不是吗？

如何让wordpress能够连接到MariaDB容器？
