nginx负载均衡的demo

在内网中有五个服务器，上面分别都部署了两个服务，然后利用下面的方式，就可以简单进行负载均衡了。

upstream test.com { 
                server 192.168.0.201:19876;
                server 192.168.0.201:19877;
                server 192.168.0.202:19876;
                server 192.168.0.202:19877;
                server 192.168.0.203:19876;
                server 192.168.0.203:19877;
                server 192.168.0.204:19876;
                server 192.168.0.204:19877;
                server 192.168.0.205:19876;
                server 192.168.0.205:19877;
            }
            
server{ 
    listen 80;  
    location / { 
        proxy_pass         http://test.com; 
        proxy_set_header   Host             $host; 
        proxy_set_header   X-Real-IP        $remote_addr; 
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for; 
    } 
}
