nginx 配置简单的负载均衡

# 负载均衡：设置domain
upstream domain {
    server localhost:8000;
    server localhost:8001;
}
server {  
        listen       8080;        
        server_name  localhost;

        location / {
            # root   html; # Nginx默认值
            # index  index.html index.htm;
            
            proxy_pass http://domain; # 负载均衡配置，请求会被平均分配到8000和8001端口
            proxy_set_header Host $host:$server_port;
        }
}
