安装 GitLab Runner

1. 安装

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

2. 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

3. 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

4. 注册 GitLab Runner

gitlab-runner register

5. 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/

6. 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

7. 提示：**Enter a description for the runner:
   **输入流水线的名称，默认为 CentOS 主机名
8. 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
9. 提示：Enter optional maintenance note for the runner:

输入流水线的描述，可为空

10. 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

11. 提示：**Enter the default Docker image (for example, ruby:2.7):
    **输入默认docker镜像
12. 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"

13. 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

14. 在 https://gitlab.example.com/admin/runners 、https://192.168.61.129/admin/runners 中可看到流水线的状态
15. 列出所有
