ubuntu 16.04에 jenkins 설치

ubuntu 16.04 서버에 jenkins 설치하는 방법이다. 설치는 apt 를 이용해서 진행한다.

1. openjdk 8 설치

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt update
sudo apt-get install openjdk-8-jdk

jenkins 를 설치하기 위해서는 java를 먼저 설치해야 한다.

2. jenkins 설치

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
sudo add-apt-repository 'deb https://pkg.jenkins.io/debian-stable binary/'
sudo apt update
sudo apt install jenkins

3. nginx 설정

upstream jenkins {
  keepalive 32; # keepalive connections
  server 127.0.0.1:8080; # jenkins ip and port
}
 
server {
  listen          80;       # Listen on port 80 for IPv4 requests

  server_name     jenkins.example.com;

  #this is the jenkins web root directory (mentioned in the /etc/default/jenkins file)
  root            /var/run/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
  }

}

jenkins 접속 요청을 nginx 에서 받아 jenkins 로 넘겨주도록 한다.

nginx 설정을 리로드 한 후 브라우저에서 jenkins.example.com 로 접속하여 화면의 표시대로 설정을 진행한다.
