python怎么启动80端口_nginx 小白， nginx 启动后 80 端口无法访问

环境：阿里云 centos7

flask web 应用， gunicorn 已经启动，访问ip:8888正常访问

nginx 正常启动，无法直接访问 ip ，浏览器显示： This site can ’ t be reached

我有两个配置文件conf/nginx.conf, site-enable/kaoshixing.conf,内容分别如下：

user root;

worker_processes auto;

# worker_cpu_affinity auto;

error_log /home/admin/kaoshixing/nginx/logs/error.log;
