配置：

服务器1：

     server 192.168.1.126:8081 weight=1 ;
     server 192.168.1.125:8081 weight=2 ;

    }
}
 

ps：80端口是用来访问的，8081端口是用来转发的。

服务器2：

server {
    listen       8081;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
    location ~ .*\.(gif|jpg|jpeg|bmp|png|ico|txt|js|css)$
    {
        root /usr/share/nginx/html/tp/public;
    }
    location / {
        root   /usr/share/nginx/html;
        index index.php index.html index.htm;

    }
    #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   /usr/share/nginx/html/tp/public;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        
    #fastcgi_split_path_info ^(.+\.php)(.*)$; #新加第一句
        fastcgi_param PATH_INFO $fastcgi_path_info;#新加第二句
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
           fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info; 
    include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache\’s document root
    # concurs with nginx\’s one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
 

就这样！（记得开放端口）
