lnmp 多站点配置负载均衡

1.虚拟机安装3个centos

2.三台服务器IP:

192.168.191.129（主）
192.168.191.130
192.168.191.131

3.分别在3台服务器的vhost目录下新建配置文件，我这里统一命名为load_balance.conf

主服务器配置如下：

upstream  load_balance {
        # 设置负载均衡的机器列表(采用轮询的方式)
        server  192.168.191.130:80;
        server  192.168.191.131:80;
  }



server {  
    listen  80;
    server_name www.upstream.com upstream.com;  
    location / {  
        #设置反向代理  
        proxy_pass  http://load_balance;  
        proxy_set_header   Host             $host;  
        proxy_set_header   X-Real-IP        $remote_addr;  
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;  
    }  
  
  
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$  
    {  
        # 设置静态文件的反向代理  
        proxy_pass   http://load_balance;  
        expires      30d;  
    }  

    location ~ .*\.(js|css)?$  
    {  
        # 设置静态文件的反向代理  
        proxy_pass  http://load_balance;  
        expires      12h;  
    }  
  
    }  

从服务器配置如下：

 1 server {  
 2     listen  80;  
 3     server_name www.upstream.com upstream.com;  
 4     index index.html index.htm index.php;  
 5     root  /home/wwwroot/load_balance;   
 6   
 7     location ~ \.php$ {
 8         include /usr/local/nginx/conf/fastcgi.conf; 
 9         fastcgi_pass unix:/tmp/php-cgi.sock;
10     fastcgi_param SCRIPT_FILENAME /home/wwwroot/load_balance$fastcgi_script_name;
11     }
12 
13     location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$  
14     {  
15         expires      30d;  
16     }  
17   
18   
19     location ~ .*\.(js|css)?$  
20     {  
21         expires      12h;  
22     }  
23 }

重启nginx服务

service nginx restart

然后在 /home/wwwroot/load_balance 目录新建文件，输出不同的内容，测试

访问http://www.upstream.com/刷新页面，基本上是每刷新一次，更换一次，实现了负载均衡
