NGINX<\/strong> is a high-performance, open-source web server and reverse proxy server. It is well-known for its speed, scalability, and efficiency, particularly when handling a large number of concurrent connections.<\/p>\n You get the following error when you start Nginx server.<\/p>\n ubuntu nginx[4686]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)<\/strong><\/p>\n The problem root cause is that the listening port is already in use. To change the port that NGINX listens on, you need to modify the NGINX configuration file.<\/p>\n Steps to change the port are as follows:<\/p>\n Open the NGINX Configuration File: You can use any text editor like nano or vim. The main configuration file is usually located at<\/p>\n \/etc\/nginx\/nginx.conf, but some systems might use<\/p>\n \/etc\/nginx\/sites-available\/default<\/p>\n or<\/p>\n \/etc\/nginx\/conf.d\/default.conf<\/p>\n <\/p>\n For example, open the NGINX configuration file with nano:<\/p>\n $ sudo nano \/etc\/nginx\/nginx.conf<\/strong><\/p>\n Find the listen<\/strong> Directive: Look for the listen directive in the configuration file. This tells NGINX which port it should be listening on. By default, it might look like this:<\/p>\n Change the Port: Modify the listen directive to the new port you want NGINX to listen on. For example, to change it to port 8080, you would modify it like this:<\/p>\n <\/p>\n Save and Exit: After making the change, save the file and exit the editor. If you’re using nano, press CTRL + O<\/strong> to save, then CTRL + X<\/strong> to exit.<\/p>\n Check NGINX Configuration<\/p>\n It’s always a good idea to check if the configuration is valid before restarting NGINX. Run:<\/p>\n $ sudo nginx -t<\/strong><\/p>\n If the output says the configuration is OK, you can proceed. If there are errors, fix them before proceeding.<\/p>\n Restart NGINX<\/p>\n After making the changes, restart NGINX for the changes to take effect:<\/p>\n $ sudo systemctl restart nginx<\/strong><\/p>\n Allow the New Port through the Firewall (if applicable): If you’re using a firewall (e.g., ufw), make sure the new port is allowed. $ sudo ufw allow 8080<\/strong><\/p>\n Now, NGINX should be listening on the new port! To verify, you can check with:<\/p>\n $ sudo netstat -tuln | grep 8080<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" How to change listening Nginx Port NGINX is a high-performance, open-source web server and reverse proxy server.
