jenkins 做什么

Jenkins 是持续集成中绕不过的一个服务、用作基于 gitlab 的发布系统
开发提交代码到 gitlab，通过 Jenkins 拉取代码 发布到测试环境

环境需求

  • Java
  • nginx

官网下载最新版 war 包，采用 Java 命令直接启动是最简便快捷的方式

1
java -jar jenkins.war --httpport=8000

如何自定义 Jenkins_Home 目录

Jenkins 启动默认路径为 ~/.jenkins ,如何改变此目录呢？

  • 环境变量增加 JENKINS_HOME 路径
1
2
3
vim /etc/profile
JENKINS_HOME=/opt/jenkins
source  /etc/profile

然后再启动即可

java -jar jenkin.war --httpport=8000

通过 Nginx 进行反向代理

vim jenkins.conf

启动后，打开浏览器进行初始化安装插件等
