jenkins 搭建过程

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

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

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

upstream jenkins {
  server 127.0.0.1:8000; # jenkins ip and port
}

server {
  listen         443 ssl;      # https

  server_name     ci.xxxx.com;
  ssl_certificate vhost/xxxx.com.crt;
  ssl_certificate_key vhost/xxxx.com.key;

  #this is the jenkins web root directory (mentioned in the /etc/default/jenkins file)
  root            /opt/jenkins/war/;

  #access_log      /var/log/nginx/jenkins/access.log;
  #error_log       /var/log/nginx/jenkins/error.log;
  ignore_invalid_headers off; #pass through headers from Jenkins which are considered invalid by Nginx server.

  location ~ "^/static/[0-9a-fA-F]{8}\/(.*)$" {
    #rewrite all static files into requests to the root
    #E.g /static/12345678/css/something.css will become /css/something.css
    rewrite "^/static/[0-9a-fA-F]{8}\/(.*)" /$1 last;
  }

  location /userContent {
    #have nginx handle all the static requests to the userContent folder files
    #note : This is the $JENKINS_HOME dir
  root /var/lib/jenkins/;
    if (!-f $request_filename){
      #this file does not exist, might be a directory or a /**view** url
      rewrite (.*) /$1 last;
    break;
    }
  sendfile on;
  }
  location / {
      sendfile off;
      proxy_pass         http://jenkins;
      proxy_redirect     default;
      proxy_http_version 1.1;

      proxy_set_header   Host              $host;
      proxy_set_header   X-Real-IP         $remote_addr;
      proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
      proxy_set_header   X-Forwarded-Proto $scheme;
      proxy_max_temp_file_size 0;

      #this is the maximum upload size
      client_max_body_size       10m;
      client_body_buffer_size    128k;

      proxy_connect_timeout      90;
      proxy_send_timeout         90;
      proxy_read_timeout         90;
      proxy_buffering            off;
      proxy_request_buffering    off; # Required for HTTP CLI commands in Jenkins > 2.54
      proxy_set_header Connection ""; # Clear for keepalive
      # 如果用到 blue ocean 插件则配置以下条目
      if ($request_uri ~* "/blue(/.*)") {
         proxy_pass http://jenkins/blue$1;
         break;
      }
  }

}

启动后，打开浏览器进行初始化安装插件等
