安装GItlab-Runner

1. 安装最新的Git 2.0以上版本，版本低很容易报错

   https://ius.io/setup

   yum install \
   https://repo.ius.io/ius-release-el7.rpm \
   https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm -y
   
   yum search git
   
   yum install git224 -y
   
   git --version
   

2. 安装仓库源

   https://docs.gitlab.com/runner/install/linux-repository.html

   # For RHEL/CentOS/Fedora
   curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh" | sudo bash
   

3. 安装Gitlab-Runner

   yum install gitlab-runner -y
   

4. 查看Runner配置

   vi /etc/systemd/system/gitlab-runner.service
   

5. 切换到Runner用户，并配置mvn等环境变量

   su - gitlab-runner
   
   vi .bash_profile
   
   # User specific environment and startup programs
   MAVEN_HOME=/opt/apache-maven-3.6.3/
   PATH=$PATH:$HOME/.local/bin:$HOME/bin:/$MAVEN_HOME/bin
   export PATH
   
   

6. 给Runner用户增加docker权限

   1. 查询是否有docker组

      cat /etc/group | grep docker
      

      如果没有可以通过该命令添加(一般默认是有的)

      sudo groupadd docker
      

   2. 将当前用户添加到docker组

      sudo usermod -aG docker gitlab-runner
      

   3. 重启docker服务

      sudo systemctl restart docker.service
      

7. 注册Runner为shellrunner

    gitlab-runner register
   

   [gitlab-runner@cdh-upgrade-2 ~]$ gitlab-runner register
   Runtime platform                                    arch=amd64 os=linux pid=28102 revision=7a6612da version=13.12.0
   WARNING: Running in user-mode.
   WARNING: The user-mode requires you to manually start builds processing:
   WARNING: $ gitlab-runner run
   WARNING: Use sudo for system-mode:
   WARNING: $ sudo gitlab-runner...
   Enter the GitLab instance URL (for example, https://gitlab.com/):
   http://10.30.20.182/
   Enter the registration token:
   2xZAQReuYCDwFMDYfh8c
   Enter a description for the runner:
   [cdh-upgrade-2]:
   Enter tags for the runner (comma-separated):
   
   Registering runner... succeeded                     runner=2xZAQReu
   Enter an executor: docker-ssh+machine, custom, docker-ssh, parallels, shell, virtualbox, docker+machine, docker, ssh, kubernetes:
   shell
   Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
   

8. 查看运行状况

   # gitlab-runner status
   # gitlab-runner list
   # gitlab-runner restart
   

其他问题

Gitlab的Gravatar头像无法显示的问题

通过gitlab搭建的git仓库，由于Gravatar被墙了，导致Gravatar头像无法显示。总觉得怪怪的。

社区版gitlab解决办法：

vi /var/opt/gitlab/gitlab-rails/etc/gitlab.yml

将plain_url改为

#plain_url:      # default: http://www.gravatar.com/avatar/%{hash}?s=%{size}&d=identicon
plain_url:     http://gravatar.duoshuo.com/avatar/%{hash}?s=%{size}&d=identicon

然后执行

gitlab-ctl restart
gitlab-rake cache:clear RAILS_ENV=production
