nginx listener port 80

To make nginx listen to port 80, you need to modify the listen instruction in the configuration file to listen 80, and check the user permissions to ensure that you have root permissions. Finally, reload nginx and verify that the listening port is correct.

nginx listener port 80

In order for nginx to listen to port 80, the following configuration is required:

1. Modify the configuration file

By default, nginx listens to port 8080. To change to port 80, modify the configuration file nginx.conf under the nginx configuration directory.

In the http block, look for the following line:

 <code>listen 8080;</code>

Change it to:

 <code>listen 80;</code>

2. Check permissions

Without root permissions, nginx will not be able to bind to port 80. You can check the user's permissions using the following command:

 <code>sudo -u <user> nginx -t</user></code>

where <user></user> is the user running nginx.

3. Reload nginx

After modification, nginx needs to be reloaded to apply the changes. The following commands can be used:

 <code>sudo systemctl reload nginx</code>

4. Verify the changes

You can verify whether nginx is listening to port 80 through the following command:

 <code>sudo netstat -tlnp | grep 80</code>

If you see the following output, it means nginx has successfully listened to port 80:

 <code>tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1150/nginx</code>
