大致流程

在http模块中配置upstream
在server模块中将服务器与upstream绑定

配置本机多端口服务器（模拟多台服务器）

server {
        listen       82;
        server_name  127.0.0.1;
        root   "C:\phpStudy\WWW\test2";
        location / {
            index  index.html index.htm index.php;
            #autoindex on;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}
server {
        listen       81;
        server_name  127.0.0.1 phpStudy.net;
        root   "C:\phpStudy\WWW\test1";
        location / {
            index  index.html index.htm index.php;
            #autoindex on;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

配置 upstream

upstream 参数

server 192.168.0.100:80 : 负载均衡后端RealServer的IP或者域名，端口不写的话默认为80。高并发场景用域名，再通过DNS进行负载均衡

server : 反向代理后端RealServer的IP或者域名，端口不写的话默认为80。高并发场景用域名，再通过DNS进行负载均衡
weight : 权重，默认为1，权重越大接收的请求越多
max_fails : 最大尝试的失败次数，默认为1,0表示禁止失败尝试
fail_timeout : 失败超时时间，默认是10秒，通常3s左右比较合适
backup : 热备配置，前段RealServer出现问题后会自动上线backup服务器
down : 标志服务器不可用，这个参数通常配合IP_HASH使用

upstream 设置

http {
    include       mime.types;
    default_type  application/octet-stream;
    #access_log logs/access.log main;
    upstream backend {
             server 127.0.0.1:81 weight=1;(之前配置的两个本机端口)
             server 127.0.0.1:82 weight=3;
         }
  }

Server 绑定

server {
        listen       80;
        server_name  fronthome.com;
        #charset koi8-r;
        #access_log logs/host.access.log main;
        root   "C:\phpStudy\WWW\advanced\frontend\web";
        location / {
           index  index.html index.htm index.php l.php;
           autoindex  on;
           proxy_pass  http://backend;//通过这里来绑定我们之前配置的upsteam
        }
    }
