GitLab 自动化构建

发表于 | 分类于 | 阅读次数: | 浏览 次
  • GitLab CI/CD 是GitLab内置的工具，用于通过连续方法进行软件开发
  • 持续集成 的工作原理是将小的代码块推送到Git存储库中托管的应用程序代码库中，并且每次推送都运行一系列脚本来构建，测试和验证代码更改，然后再将其合并到主分支中。
  • GitLab Runner 是一个开源项目，用于运作任务，并把结果发送回GitLab，它与GitLab CI一起使用。

环境

  • 服务器 CentOS 7

GitLab 安装

  • 安装文档
    https://about.gitlab.com/install/#centos-7

  • 修改配置文件

    vi /etc/gitlab/gitlab.rb
    external_url 'http://192.168.235.128:9090'
    nginx['listen_port'] = 9090

    vi /var/opt/gitlab/nginx/conf/gitlab-http.conf
    server {
        listen *:9090;
        server_name 192.168.235.128;

  • 使配置生效

    1
    gitlab-ctl reconfigure

  • 启动

    1
    gitlab-ctl start

GitLab Runer 安装

  • 安装文档
    https://docs.gitlab.com/runner/install/linux-manually.html

  • 项目中配置
    默认 gitlab-runner 安装使用 gitlab-runner 用户执行命令，这里会遇到用户权限问题，需要修改用户权限或者修改默认用户。

    修改默认用户为 root

    1
    2
    3
    sudo gitlab-runner uninstall
    sudo gitlab-runner install --user=root --working-directory=/home/gitlab-runner
    sudo gitlab-runner restart

    查看用户是否修改成功

    [root@localhost ~]# ps aux | grep gitlab-runner
    root      1174  1.1  0.2 138140 20708 ?        Ssl  08:22   3:51 /usr/bin/gitlab-runner run --working-directory /home/gitlab-runner --config /etc/gitlab-runner/config.toml --service gitlab-runner --syslog --user root
    root     17883  0.0  0.0 112828   984 pts/1    S+   13:54   0:00 grep --color=auto gitlab-runner

    对需要自动化构建的项目注册 gitlab-runner

    Running in system-mode.

    Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):

项目中新建 .gitlab-ci.yml 文件

  • 安装 sshpass ssh只能回车后输入密码登录

    1
    yum -y install sshpass

  • 添加 ssh key 自动化执行脚本，clone项目避免输入用户名和密码；没有 ssh key 需要自己手动生成

    获取 key

    1
    cat ~/.ssh/id_rsa.pub

    生成 key

    1
    ssh-keygen -t rsa -C "your.email@example.com" -b 4096

    配置 key
    值参考截图

  • 设置变量 .yml 文件中会做 ssh 登录操作，像 password，ip 这些信息不便直接写在脚本中
    值参考截图

  • 前端 .yml 文件示例
