## 一、安装Nginx ##

*  [window10安装nginx【1.8.1版本】][window10_nginx_1.8.1]
 *  [CentOS7 安装 nginx ][CentOS7 _ 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 ###

## 四、其它 ##

### 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） ###
