Centos安装Jenkins, Nginx配置代理

官网地址：

https://jenkins.io

安装文档

https://pkg.jenkins.io/redhat-stable/

示例

使用yum方式安装jenkins：

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
yum install fontconfig java-11-openjdk
yum install jenkins

配置代理
官方文档：
https://www.jenkins.io/doc/book/system-administration/reverse-proxy-configuration-with-jenkins/reverse-proxy-configuration-nginx/
示例：

upstream jenkins {
  keepalive 32; # keepalive connections
  server 127.0.0.1:8080; # jenkins ip and port
}

# Required for Jenkins websocket agents
map $http_upgrade $connection_upgrade {
  default upgrade;
  '' close;
}

server {
  listen          80;       # Listen on port 80 for IPv4 requests

  server_name     jenkins.example.com;  # replace 'jenkins.example.com' with your server domain name

  # this is the jenkins web root directory
  # (mentioned in the output of "systemctl cat jenkins")
  root            /var/run/jenkins/war/;

  access_log      /var/log/nginx/jenkins.access.log;
  error_log       /var/log/nginx/jenkins.error.log;

  # pass through headers from Jenkins that Nginx considers invalid
  ignore_invalid_headers off;

  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 userContent folder
    # 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;

      # Required for Jenkins websocket agents
      proxy_set_header   Connection        $connection_upgrade;
      proxy_set_header   Upgrade           $http_upgrade;

      proxy_set_header   Host              $http_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
      proxy_set_header Connection ""; # Clear for keepalive
  }

}

重启nginx之后，查看nginx访问日志，会出现如下错误：

若出现该错误，需要关闭linux系统的selinux:
查看SELinux状态
如果SELinux status参数为enabled即为开启状态

/usr/sbin/sestatus -v

关闭SELinux：

1、临时关闭（不用重启机器）：

setenforce 0 ##设置SELinux 成为permissive模式

##setenforce 1 设置SELinux 成为enforcing模式

2、修改配置文件需要重启机器：

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

启动nginx

systemctl restart nginx
