如何在CentOS 安装极狐GitLab Runner?
本文作者:徐晓伟
GitLab 是一个全球知名的一体化 DevOps 平台,很多人都通过私有化部署 GitLab 来进行源代码托管。极狐GitLab 是 GitLab 在中国的发行版,专门为中国程序员服务。可以一键式部署极狐GitLab。
基于 CentOS 和 极狐GitLab 官方仓库脚本 安装/配置 GitLab Runner
文档
安装 GitLab Runner
-
安装
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh | sudo bash yum -y install gitlab-runner
-
使用 root 用户运行 GitLab Runner
- __根据用户的需要操作此步骤,让 GitLab Runner 使用 root 用户运行流水线,可能会带来风险,如:流水线中写了 rm -rf /** __
- 推荐使用 Docker 执行前,防止出现上述情况
# 以下设置在升级 GitLab Runner 后将失效,需要重新设置一次 # 查看当前 runner 运行的用户 ps aux | grep gitlab-runner # 删除gitlab-runner sudo gitlab-runner uninstall # 安装并设置--user(例如我想设置为root) gitlab-runner install --working-directory /home/gitlab-runner --user root # 重启gitlab-runner sudo service gitlab-runner restart # 再次执行会发现--user的用户名已经更换成root了 ps aux | grep gitlab-runner

配置证书信任
# 自己生成的证书,如果不进行信任,注册时可能出现的问题: # ERROR: Registering runner... failed runner=6iuLhyWx status=couldn't execute POST against https://gitlab.example.com/api/v4/runners: Post "https://gitlab.example.com/api/v4/runners": x509: certificate is not valid for any names, but wanted to match gitlab.example.com # 下列执行时,需要本机能使用 GitLab 域名访问 # 可以修改 本机 /etc/hosts 文件解决 # 如果域名未解析,会出现 # ERROR: Registering runner... failed runner=z4uLTqoa status=couldn't execute POST against https://gitlab.example.com/api/v4/runners: Post "https://gitlab.example.com/api/v4/runners": dial tcp: lookup gitlab.example.com on 192.168.61.2:53: no such host # 如果创建证书时,未设置“Common Name (e.g. server FQDN or YOUR name) []”时,会出现 # ERROR: Registering runner... failed runner=z4uLTqoa status=couldn't execute POST against https://gitlab.example.com/api/v4/runners: Post "https://gitlab.example.com/api/v4/runners": x509: certificate is not valid for any names, but wanted to match gitlab.example.com # 重新设置了域名证书,需要执行 sudo gitlab-ctl restart,如果修改了 /etc/gitlab/gitlab.rb 文件,需要先执行 sudo gitlab-ctl reconfigure,再执行 sudo gitlab-ctl restart # 生成的证书不满足GitLab Runner的检查时,会出现下列错误,请根据前面章节中的内容重新生成 # ERROR: Registering runner... failed runner=z4uLTqoa status=couldn't execute POST against https://gitlab.example.com/api/v4/runners: Post "https://gitlab.example.com/api/v4/runners": x509: certificate relies on legacy Common Name field, use SANs instead # 如果域名证书未生效,或者已过期,会出现下面的错误 # x509: certificate has expired or is not yet valid: current time 2022-11-15T20:45:12+08:00 is before 2022-11-15T19:49:27Z # # sudo mkdir -p /etc/gitlab-runner/certs # 本文使用域名是IP:192.168.80.14 # 可根据自己的需要,修改下方的域名及端口 # 使用客户端下载 GitLab 实例的证书 openssl s_client -showcerts -connect 192.168.80.14:443 -servername 192.168.80.14 < /dev/null 2>/dev/null | openssl x509 -outform PEM > /etc/gitlab-runner/certs/192.168.80.14.crt # openssl s_client -showcerts -connect gitlab.example.com:443 -servername gitlab.example.com < /dev/null 2>/dev/null | openssl x509 -outform PEM > /etc/gitlab-runner/certs/gitlab.example.com.crt # 验证文件是否已正确安装 echo | openssl s_client -CAfile /etc/gitlab-runner/certs/192.168.80.14.crt -connect 192.168.80.14:443 -servername 192.168.80.14 # echo | openssl s_client -CAfile /etc/gitlab-runner/certs/gitlab.example.com.crt -connect gitlab.example.com:443 -servername gitlab.example.com
-
注册 GitLab Runner
gitlab-runner register
-
提示:Enter the GitLab instance URL (for example, https://gitlab.com/):
输入 GitLab 的地址
https://192.168.80.14 # https://gitlab.example.com/
-
提示:Enter the registration token:
# 复制 https://192.168.80.14/admin/runners 页面中的 token(点击:注册一个Runner即可获取) # 复制 https://gitlab.example.com/admin/runners 页面中的 token(点击:注册一个Runner即可获取) 6iuLhyWxqypcyaNtUG_C
-
提示:Enter a description for the runner:
输入流水线的名称,默认为 CentOS 主机名
-
提示:Enter tags for the runner (comma-separated):
输入流水线的标签名(非Git仓库的标签),即:.gitlab-ci.yml 文件中标签,可为空,**为空时允许所有未指定标签的流水线使用,可在GitLab页面中进行随时调整 **
-
提示:Enter optional maintenance note for the runner:
输入流水线的描述,可为空
-
提示:Registering runner... succeeded runner=6iuLhyWx
Enter an executor: docker, docker-ssh, parallels, shell, docker-ssh+machine, instance, kubernetes, custom, ssh, virtualbox, docker+machine:选择流水线执行器
# 输入 docker,用于后面的 GitLab Pages 做准备 docker
-
提示:Enter the default Docker image (for example, ruby:2.7):
输入默认docker镜像
-
出现下列语句,说明流水线已注册成功: /etc/gitlab-runner/config.toml 是GitLab Runner配置文件的位置
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! Configuration (with the authentication token) was saved in "/etc/gitlab-runner/config.toml"
-
修改流水线配置,使其同时可以执行多个任务
vim /etc/gitlab-runner/config.toml
# 同一时间支持运行的最大任务数 concurrent = 10
-
在以下地址中可看到流水线的状态
-
列出所有
gitlab-runner list
-
查看状态
gitlab-runner status
-
停止
gitlab-runner stop
-
启动
gitlab-runner start
