一、安装Nginx

• window10安装nginx【1.8.1版本】
• CentOS7 安装 nginx

选择一个安装即可。

二、Nginx配置文件修改

map $http_upgrade $connection_upgrade {
	default upgrade;
	'' close;
}

upstream xdx97.com {
	server 127.0.0.1:1997;
	server 127.0.0.1:1998;
}

server {
	listen 8089;
	location / {
		proxy_pass http://xdx97.com;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection $connection_upgrade;
	}
}

完整的nginx.conf配置

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    

    sendfile        on;
   
    keepalive_timeout  65;

    server {
        listen       9876;
        server_name  localhost;

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


        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
	map $http_upgrade $connection_upgrade {
		default upgrade;
		'' close;
	}

	upstream xdx97.com {
		server 127.0.0.1:1997;
		server 127.0.0.1:1998;
	}

	server {
		listen 8089;
		location / {
			proxy_pass http://xdx97.com;
			proxy_http_version 1.1;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection $connection_upgrade;
		}
	}
}

三、测试

3-1、开启你本地的两个服务

3-2、使用下面这个在线工具进行测试

3-3、测试结果如下

四、其它

nginx60s_115">4-1、nginx默认60s没有消息传输，就会中断连接。

解决办法一： 把这个60s，设置的大一些。

proxy_read_timeout 600s; 

具体位置

server {
	listen 8089;
	location / {
		proxy_pass http://xdx97.com;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection $connection_upgrade;
		proxy_read_timeout 600s; 
	}
}

解决办法二： 前端写一个定时方法，定时去请求建立心跳连接。

4-2、Nginx实现负载均衡Linux版本（六种负载策略）
