nginx的负载均衡配置

nginx.conf:

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
########指定转给哪个服务器##########    
upstream mynginx {
        server node3:8080;
        server node4:8080;
}
    server {
        listen       80;
        server_name  localhost;
        location / {
#########反向代理出去，要和upstream 后的地址一样#####
                proxy_pass http://mynginx/;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

upstream mynginx {
        server node3:8080;
        server node4:8080;
}
对应：

location / {
                proxy_pass http://mynginx/;
        }
