一、添加yum源

curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh | sudo bash

二、安装gitlab-runner

yum install gitlab-runner -y

三、配置gitlab-runner

向GitLab-CI注册一个Runner需要两样东西：GitLab-CI的url和注册token。
其中，token是为了确定你这个Runner是所有工程都能够使用的Shared Runner还是具体某一个工程才能使用的Specific Runner。

如果要注册Shared Runner，你需要到管理界面的Runners页面里面去找注册token。

[root@dx-cdh3 cmdb]# gitlab-runner register
Running in system-mode.                            

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://gitlab.clife.cn/
Please enter the gitlab-ci token for this runner:
jmGuf9k2WsssNaxsBGcnJ6T
Please enter the gitlab-ci description for this runner:
[dx-cdh3]: share_runner
Please enter the gitlab-ci tags for this runner (comma separated):

Registering runner... succeeded                     runner=jmGuf9k2
Please enter the executor: shell, virtualbox, docker+machine, docker-ssh+machine, kubernetes, docker, docker-ssh, parallels, ssh:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

四、如果需要使用docker构建服务跟发布，添加用户到docker用户组

usermod -a -G docker gitlab-runner
