简单的nginx+2台tomcat负载均衡(自己记录)

}

上面是nginx的conf文件夹的nginx.conf文件配置。

首先要配置两台tomcat的端口号,确保两台tomcat能正常运行,然后主要是下面配置负载均衡。

upstream myserver {  
      #通过client的IP进行映射  
      #ip_hash;  
      # 负载均衡设置,weight越大越优先分配  
      #server  localhost:8099  weight=5;  
      server  127.0.0.1:8100 weight=1; 
      server  127.0.0.1:8099 weight=1;
    }

nginx监听端口和域名地址,我的域名地址就在本机的host文件配置,就想localhost一样

 server {
        listen		80;
        server_name  xym.com;

       ...
       }

下面是跳转的代理配置:

 location / {
            root   html;
            index  index.html index.htm;
	    #代理配置
	    proxy_pass http://myserver;  # "myserver"是上面"upstream"配置的名称
	    #关闭重定向
	    #proxy_redirect off;
	    proxy_redirect default;
        }
