Gitlab CI Symfony:SQLSTATE [HY000] [2002] Connection拒绝了

Question

每次有人推送代码时,我都会使用gitlab运行单元测试.我在作曲家安装期间遇到此错误.

> 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.也许我的错误是显而易见的,但我看不到它.

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".这在GitLab文档的其中一节中有所介绍:

可以在主机名mysql下访问MySQL的服务容器.因此,为了访问您的数据库服务,您必须连接到名为mysql的主机,而不是socket或localhost.
