nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

重新加载nginx服务

1	[iyunv@nginx-web ~]# /usr/local/nginx/sbin/nginx -s reload

在linux服务器上更改hosts文件

1 2	[iyunv@nginx-web ~]# tail -n 1 /etc/hosts 192.168.33.131bbs.zxl.com

使用curl进行访问下
