Docker:在Drupal安装期间，链接到mysql容器的Drupal容器无法连接到mysql [英] Docker : Drupal container linked to mysql container can't connect to mysql during Drupal installation

问题描述

我对docker来说还很陌生，我刚刚经历了CMS，以了解它们的配置有多么容易.到目前为止，Wordpress和Joomla都已签出.

I'm fairly new to docker, and I've just been going through the CMS's to see how easy they are to configure. So far, Wordpress and Joomla check out.

当我运行链接到mysql的drupal容器时，我会转到drupal安装屏幕，并在其中显示连接数据库的位置，并使用我的根凭据和数据库主机为"localhost"，并在尝试连接时收到错误.我已附上一张图片，向您显示输出. drupal-config-db-output-error

When I run the drupal container linked to mysql, I get to the drupal installation screen and where it says to connect the DB, and I use my root credentials and db host being 'localhost', and receive errors trying to connect. I've attached an image to show you the output.drupal-config-db-output-error

我得到的错误:

Failed to connect to your database server. The server reports the following message: SQLSTATE[HY000] [2002] No such file or directory.

任何对此的帮助都会很棒.我试图查看是否可以使用配置文件访问物理卷，但使用Kitematic找不到它们.

Any help on this would be great. I tried to see if I could access the physical the volume with the config files, but I couldn't find them using Kitematic.

谢谢！

推荐答案

以下 docker组成文件将启动Drupal连接到另一个运行Mysql的容器

The following docker compose file will startup Drupal connected to another container running Mysql

db:
  image: mysql
  environment:
    - MYSQL_ROOT_PASSWORD=letmein
    - MYSQL_DATABASE=drupal
    - MYSQL_USER=drupal
    - MYSQL_PASSWORD=drupal
  volumes:
    - /var/lib/mysql
web:
  image: drupal
  links:
    - db:mysql
  ports:
    - "8080:80"
  volumes:
    - /var/www/html/sites
    - /var/www/private

请注意，drupal容器使用 docker链接.这将创建一个名为"mysql"的/etc/hosts条目.运行drupal安装屏幕时，请使用该名称代替"localhost".

Note that the drupal container uses docker links. This will create a /etc/hosts entry called "mysql". Use this instead of "localhost" when running the drupal install screens.

自最初起草此答案以来，docker compose文件语法已更改.

The docker compose file syntax has changed since this answer was originally drafted.

这是更新的语法

version: '2'
services:
  mysql:
    image: mysql
    environment:
      - MYSQL_ROOT_PASSWORD=letmein
      - MYSQL_DATABASE=drupal
      - MYSQL_USER=drupal
      - MYSQL_PASSWORD=drupal
    volumes:
      - /var/lib/mysql
  web:
    image: drupal
    depends_on:
      - mysql
    ports:
      - "8080:80"
    volumes:
      - /var/www/html/sites
      - /var/www/private
