The nginx80 port under Alibaba Cloud cannot be used?

Question

In order to prevent nginx from jumping to its default welcome page, I deleted /etc/nginx/sites-enabled/defalt. ps: The running environment is nginx installed by Alibaba Cloud + ubuntu14.04 + apt-get.

Use /etc/nginx/sites-enabled/mysite.conf to listen to port 80

server {
    listen 80;
    server_name domainname;

    location /static/ {
        alias /srv/http/mysite/staitc/;
    }

    location / {
        uwsgi_pass 127.0.0.1:8001;
        include     /etc/nginx/uwsgi_params;
    }
}

my question

1. 但是如果监听8080这些端口，比如domainname:8080可以跳转到正确的界面
2. 请问这是怎么回事呢？

The default /etc/nginx/nginx.conf file has not been modified. The following is its content:

Answer 1

Pay attention to this paragraph,

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

The configuration files in the two directories will be read here.
You need to make sure that there are no other configuration files in /etc/nginx/conf.d/, otherwise it will be loaded first and overwrite your website configuration.

Also, usually there will be a default website in this directory, listening on port 80. Obviously your website is covered by this default site.
