简介

GitLab-CI
 GitLab-CI 就是一套配合 GitLab 应用的继续集成系统(当然,还有其它的继续集成系统,同样能够配合 GitLab 应用,比方 Jenkins)。而且 GitLab8.0 当前的版本是默认集成了 GitLab-CI 并且默认启用的。
GitLab-Runner
 GitLab-Runner 是配合 GitLab-CI 进行应用的。个别地,GitLab 外面的每一个工程都会定义一个属于这个工程的软件集成脚本,用来自动化地实现一些软件集成工作。当这个工程的仓库代码产生变动时,比方有人 push 了代码,GitLab 就会将这个变动告诉 GitLab-CI。这时 GitLab-CI 会找出与这个工程相关联的 Runner,并告诉这些 Runner 把代码更新到本地并执行预约义好的执行脚本。

  • 指标:代码提交到 GitLab 上,由 GitLab 的 CI 性能主动实现部署。
  • 原理:GitLab 在接管到代码提交事件时,通过.gitlab-ci.yml 的配置信息与对应节点上的 runner 进行交互。

    1. 装置 Runner
gitlab-runner 下载地址:https://mirrors.tuna.tsinghua.edu.cn/gitlab-runner/yum
CC : 区别 el6 和 el7, 去相应的目录下下载即可

rpm -ivh gitlab-runner-10.5.0-1.x86_64.rpm

还有一种形式为脚本装置(有外网拜访权限下能够应用):

curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash
yum install gitlab-ci-multi-runner
    1. 配置 Runner(可选)

默认状况,Runner 是通过 gitlab-runner 的这个用户来执行一系列操作,其工作目录也是在 gitlab-runner 的用户目录上面。如果应用默认 gitlab-runner 用户操作一些文件时常常会遇到权限问题,就须要给 gitlab-runner 赋权。咱们通过以下形式批改。

gitlab-runner uninstall # 删除服务
gitlab-runner install –working-directory /root –user root # 增加服务,别离制订工作目录和执行用户为 /root 和 root
gitlab-runner restart # 重启服务
gitlab-runner status # 查看状态
输入:gitlab-runner: Service is running!
ps -ef | grep gitlab-runner # 查看是否失效
输入:root 17454 1 0 Mar23 ? 01:18:03 /usr/bin/gitlab-runner run –working-directory
/home/jack –config /etc/gitlab-runner/config.toml –service gitlab-runner –syslog –user jack

    1. 注册 runner
      把该 Runner 信息注册给 GitLab 的 CI 服务,通知 CI”我是谁,我能做什么”。
      先关上 GitLab 上须要主动部署的我的项目界面,找到该项目标 Settings –> CI/CD –> Runners settings。不同版本的 GitLab 界面可能有些差异。

在红色的区域能够看到 URL 和 Token,这两个加起来就是该项目标惟一信息了。而后咱们 Runner 服务的 root 用户下执行以下命令


# gitlab-runner register
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...                   
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://gitlab.xxxx.com         # 填写方才看到的 URL
Please enter the gitlab-ci token for this runner:
Cxxxxxxxxxxxxx4                # 填写方才看到的 Token
Please enter the gitlab-ci description for this runner:
[dev_srv]:iuh_801_testlab_master    # 形容一下该 runner,该和.gitlab-ci.yml 文件外面配置的 tags 雷同即可
Please enter the gitlab-ci tags for this runner (comma separated):
tags_of_iuh_801_testlab_master      # 该 runner 起个名字
Whether to run untagged builds [true/false]:
[false]:                            # 间接回车
Whether to lock the Runner to current project [true/false]:
[true]:                             # 间接回车
Registering runner... succeeded                     runner=eHMqXjw9
Please enter the executor: shell, ssh, docker+machine, docker, docker-ssh, parallels, virtualbox, docker-ssh+machine, kubernetes:
shell                               # 填写 runner 执行时须要应用什么执行器,个别都填 shell 或者 docker。Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

这样就实现了 Runner 与 CI 之间的信息互注册。Runner 晓得了本人须要操作哪个我的项目,CI 也晓得了该 runner 的存在。接着刷新一下 Runners settings 界面,就会看到新注册的 Runner 了。后面有一个绿色的圆就代表注册胜利。
    1. 配置 yml 文件
      在我的项目根目录下增加一个.gitlab-ci.yml 文件。内容如下:
stages:
  - update_master
update_production_env:
  stage: update_master
  script:
    - cd /u02/nginx/html/mercial.iu95522.com
    - git pull origin master
    - if [-f "system/config.php"]; then
    -   rm -rf system/config.php
    - fi
    - cp system/config.php.master system/config.php
    - chown -R nginx.nginx *
  only:
    - master
  tags:
    - tags_of_iuh_801_mercial.iu95522.com_master
stages 下的 deploy 阐明在代码提交后 CI 须要执行 deploy 节点的内容。deploy 的 script 就是一个个 shell 命令,这里须要留神每个命令都以杠 + 空格结尾。only:只有向 dev 分支提交代码时才失效。tags:只有领有该 tags 的 Runner 才须要执行
