php - Gitlab CI Symfony : SQLSTATE[HY000] [2002] Connection refused

Question

每次有人推送代码时，我都会使用 gitlab 运行单元测试。我在 composer 安装过程中收到此错误。

> Incenteev\ParameterHandler\ScriptHandler::buildParameters
Creating the "app/config/parameters.yml" file
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache


  [Doctrine\DBAL\Exception\ConnectionException]                              
  An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused  



  [Doctrine\DBAL\Driver\PDOException]        
  SQLSTATE[HY000] [2002] Connection refused  



  [PDOException]                             
  SQLSTATE[HY000] [2002] Connection refused  


Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception

这是我的配置:

.gitlab-ci.yml文件

    # Select image from https://hub.docker.com/_/php/
    image: php:5.6

    # Select what we should cache
    cache:
      paths:
      - vendor/

    before_script:
    # Install ssh-agent if not already installed, it is required by Docker.
    # (change apt-get to yum if you use a CentOS-based image)
    - 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'

    #

 Run ssh-agent (inside the build environment)
- eval $(ssh-agent -s)

# Add the SSH key stored in SSH_PRIVATE_KEY variable to the agent store
- ssh-add <(echo "$SSH_PRIVATE_KEY")

# For Docker builds disable host key checking. Be aware that by adding that
# you are suspectible to man-in-the-middle attacks.
# WARNING: Use this only with the Docker executor, if you use it with shell
# you will overwrite your user's SSH config.
- mkdir -p ~/.ssh
- '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'

- cp ci/custom.ini /usr/local/etc/php/conf.d/custom.ini
- bash ci/docker_install.sh > /dev/null

我已阅读并遵循 gitlab 网站的说明。也许我的错误很明显，但我看不到。

当您使用在另一个容器中运行的 MySQL 时，您必须使用其主机名，而不是 127.0.0.1。 正确的数据库主机应该是“mysql”。这包含在 one of the sections 中GitLab 的文档:

The service container for MySQL will be accessible under the hostname mysql. So, in order to access your database service you have to connect to the host named mysql instead of a socket or localhost.
