gitlab-runner|gitlab-runner 部署及关联gitlab
简介
GitLab-CI
?GitLab-CI就是一套配合GitLab使用的持续集成系统(当然,还有其它的持续集成系统,同样可以配合GitLab使用,比如Jenkins)。而且GitLab8.0以后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进行使用的。一般地,GitLab里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,用来自动化地完成一些软件集成工作。当这个工程的仓库代码发生变动时,比如有人push了代码,GitLab就会将这个变动通知GitLab-CI。这时GitLab-CI会找出与这个工程相关联的Runner,并通知这些Runner把代码更新到本地并执行预定义好的执行脚本。
- 目标:代码提交到GitLab上,由GitLab的CI功能自动完成部署。
- 原理:GitLab在接收到代码提交事件时,通过.gitlab-ci.yml的配置信息与对应节点上的runner进行交互。

- 安装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
还有一种方式为脚本安装(有外网访问权限下可以使用):
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash
yum install gitlab-ci-multi-runner
-
- 配置Runner(可选)
gitlab-runner uninstall # 删除服务
gitlab-runner install --working-directory /root --user root # 添加服务,分别制定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
输出:gitlab-runner: Service is running!
ps -ef | grep gitlab-runner # 查看是否生效
输出: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

- 注册runner
把该Runner信息注册给GitLab的CI服务,告诉CI”我是谁,我能做什么”。
先打开GitLab上需要自动部署的项目界面,找到该项目的 Settings –> CI/CD –> Runners settings 。不同版本的GitLab界面可能有些差别。
- 注册runner
# 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# 填写刚才看到的URL
Please enter the gitlab-ci token for this runner:
Cxxxxxxxxxxxxx4# 填写刚才看到的Token
Please enter the gitlab-ci description for this runner:
[dev_srv]:iuh_801_testlab_master# 描述一下该runner,该和.gitlab-ci.yml文件里面配置的tags相同即可
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]:# 直接回车
Whether to lock the Runner to current project [true/false]:
[true]:# 直接回车
Registering runner... succeededrunner=eHMqXjw9
Please enter the executor: shell, ssh, docker+machine, docker, docker-ssh, parallels, virtualbox, docker-ssh+machine, kubernetes:
shell# 填写runner执行时需要使用什么执行器,一般都填shell或者docker。
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!
![](/media//202108/2021-08-12_100406.png)
这样就完成了Runner与CI之间的信息互注册。Runner知道了自己需要操作哪个项目,CI也知道了该runner的存在。接着刷新一下Runners settings界面,就会看到新注册的Runner了。
前面有一个绿色的圆就代表注册成功。
-
- 配置yml文件
在项目根目录下添加一个.gitlab-ci.yml 文件。内容如下:
- 配置yml文件
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说明在代码提交后CI需要执行deploy节点的内容。
deploy的script就是一个个shell命令,这里需要注意每个命令都以杠+空格开头。
only:只有向dev分支提交代码时才生效。
tags:只有拥有该tags的Runner才需要执行
