配置如下：

http {    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    #tcp_nopush     on;    #keepalive_timeout  0;    keepalive_timeout  65;    #gzip  on;		    server {        listen       80;        server_name  localhost;		 root html;	 index index.html;    }		server {		listen       80;		server_name  www.test.com;	}	}

增加：127.0.0.1 www.test.com

打开浏览器输入：www.test.com就可访问到nginx的默认页面了

你可以把多个不同的虚拟主机配置文件include进来，如：

http {    include       mime.types;    default_type  application/octet-stream;    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '    #                  '$status $body_bytes_sent "$http_referer" '    #                  '"$http_user_agent" "$http_x_forwarded_for"';    #access_log  logs/access.log  main;    sendfile        on;    #tcp_nopush     on;    #keepalive_timeout  0;    keepalive_timeout  65;    #gzip  on;		upstream jshop.360buy.com {		server localhost:8080;	}	    server {        listen       80;        server_name  localhost;			root html;		index index.html;    }		include vhosts/www.test.com.conf;	}
