nginx負載均衡配置

nginx版本：1.9.7

這裏主要介紹配置文件目錄conf

目錄：/usr/local/nginx/conf

包含配置文件：nginx.conf

         backends/demo.cn.conf

         sites/demo.cn.conf

              

具體文件配置如下：

#user  nobody;

worker_processes  1;

#nginx異常日誌

error_log  logs/error.log;

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {

    worker_connections  1024;    

}

http {

    fastcgi_intercept_errors on; 

        include       mime.types;

        default_type  application/octet-stream;

        log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for""::::" "$Host"';

     #nginx接收請求的日誌

     access_log  logs/access.log  main;

     sendfile        on;

     #tcp_nopush     on;

     #keepalive_timeout  0;

     #keepalive_timeout  65;

     #include mime.types;

     #gzip  on;

#負載分發具體配置文件

   include  backends/*;  數據轉發配置

   include  sites/*;  

}

數據轉發配置文件

#mvc為tomcat下係統工程名字

upstream mvc{

server 192.168.3.51:8088;  部署係統的兩台服務器之一(tomcat)

server 192.168.3.51:8089;  部署係統的兩台服務器之一(tomcat)   

}

正文處理配置文件

server{

      listen 80;  監聽端口

      server_name demo.cn;  請求主域名

      location ~ /mvc/(.*){  請求路徑中帶有   /mvc/的處理

        proxy_pass https://mvc;   

  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;

      }

}

本次demo的應用名稱為mvc，通過nginx進行訪問的路徑為 demo.cn/mvc/

在局域網訪問時  需要配置host   127.0.0.1 demo.cn

至此，demo全部配置完成，擴展使用nginx的其他功能需閱讀nginx官方文檔
