Nginx is running but not serving sites

Author：JIYIK Last Updated：2025/03/17 Views：

We recently installed nginx version 1.17 on a new machine. sites-availableThe configuration created in was symlinked to sites-enabled, but nginx is not serving any domain names.

The key point here is that nginx uses different directories conf.dto store a variety of defaultconfigurations. This configuration matches all incoming requests and takes over the processing of all requests and responses.

How nginx configuration works

Nginx sites-availablekeeps configurations located in the directory private and does not route them to the Internet. Adding configuration to sites-enabledthe directory will make it publicly available.

Nginx allows us to support multiple location configuration files. The second way to configure domains: conf.ddirectories.

The difference here is: conf.dany file located in the directory will be picked up by nginx and routed to the Internet. If you want to make a domain name inaccessible, you must delete the configuration for that domain from the conf.d folder.

Check nginx configuration

Check if there is a conf.d directory in /etc/nginx that contains the default configuration .

If the conf.d directory exists, you should check if nginx's configuration contains sites-enabledthe folder:

$ nano /etc/nginx/nginx.conf

We are interested in nginx's virtual host configuration. Nginx will probably search for configuration in the conf.dand sites-enableddirectories. Depending on the order, nginx might find the "gotta catch 'em all" configuration first.

The contents of our nginx.conf file might look like this:

user www-data;  
worker_processes auto;  
pid /run/nginx.pid;

events {  
        worker_connections 768;
}

http {  
        sendfile on;
        tcp_nopush on;

        ##
        # 虚拟主机配置
        ##
        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;  # <-- 如果希望“sites-enabled”工作，请确保此行有效
}

If we place configuration files for our domains in the sites-availableand sites-enableddirectories, conf.dthe default configuration from may override them.
