Nginx实现反向代理

此配置达到的目的就是在访问项目的时候访问域名地址，而不是真实的项目地址

前置要求：linux上已安装nginx，当然在windows系统上安装Nginx也是一样的，此处演示使用的linux；

进入到nginx的配置文件目录：vim nginx.conf

#user  nobody;
worker_processes  1;

#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 {
    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"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    }

        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration

    #server {

    #    listen       somename:8080;

    #    location / {

    #}


    # HTTPS server

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

配置文件主要添加的代码部分为

server {
      listen        80;
      server_name   manager.leyou.com;
      proxy_set_header X-Forwarded-Host $host;
      proxy_set_header X-Forwarded-Server $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      location / {
              proxy_pass http://192.168.26.15:9001;
              proxy_connect_timeout 600;
              proxy_read_timeout    600;
      }


    }

    server {
      listen        80;
      server_name  api.leyou.com;
      proxy_set_header X-Forwarded-Host $host;
      proxy_set_header X-Forwarded-Server $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      location / {
              proxy_pass http://192.168.26.15:10010;
              proxy_connect_timeout 600;
              proxy_read_timeout    600;
      }


    }

 192.168.26.15是项目所在主机地址；9001是项目启动端口；

配置完成后启动nginx

start nginx//启动nginx
nginx -s stop          // 停止nginx
nginx -s reload       // 重新加载配置文件
nginx -s quit          // 退出nginx

然后使用SwitchHosts工具，在项目所在的windows系统添加域名映射

192.168.10.128是配置nginx的linux系统地址，manager.leyou.com是nginx映射的项目访问地址；

启动本地项目，在浏览器中输入 manager.leyou.com便可以成功访问项目

另外：在访问项目的时候可能会出现502错误，日志显示如下错误

 解决办法：

将项目中host处对应的localhsot改为0.0.0.0即可。
