在 CentOS7/RHEL7 上架設 Nginx Web Server(四)

設定目標：

• 設定 Nginx Web Server，架設 Reverse Proxy Server 服務！

事前準備：

• 請先參考這一篇文件，架設好 Nginx Web Server！

快速設定流程：

1. 編寫 Nginx 預設設定檔：

   #vi /etc/nginx/nginx.conf
   (註解以下設定：)
   # server {
      :
      :
   #  }
   

2. 編寫 for proxy 的設定檔：

   #vi /etc/nginx/conf.d/proxy.conf
   upstream proxy {
       server 192.168.5.61:80;
   }
   
   server {
       listen      80 default;
       server_name www.example.com;
   
       access_log  /var/log/nginx/jenkins.access.log;
       error_log   /var/log/nginx/jenkins.error.log;
   
       proxy_buffers 16 64k;
       proxy_buffer_size 128k;
   
       location / {
           proxy_pass  http://proxy;
           proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
           proxy_redirect off;
   
           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 https;
       }
   }
   

3. 啟動 Nginx ：

   #systemctl enable nginx.service
   #systemctl start nginx.service
   

4. 啟動防火牆：

   #firewall-cmd --permanent --add-service=http
   #firewall-cmd --reload
