@Yosua,

It looks like the error is due to port 80 being already in use, which is preventing FrankenPHP from starting properly.

Check if any process is using port 80:

sudo lsof -i :80

If you see a running process (such as Apache or Nginx), you’ll need to stop or change its port.

sudo systemctl stop apache2
OR
sudo systemctl stop nginx

Restart FrankenPHP.

sudo frankenphp php-server

If you don’t want to stop services on port 80, you can change the port for FrankenPHP by adding the -p flag:

sudo frankenphp php-server -p 8080

Then, access it using http://localhost:8080.

After i follow the installation i got the issue when run sudo frankenphp php-server

can you check again? thanks!

@Promoetee,

You’re right that FrankenPHP can execute PHP CLI files, so technically, installing php-cli may not be required if you’re only using it for command-line operations. However, PHP-FPM is often used for handling web requests in a separate process, providing better performance and scalability, especially for high-traffic websites.

Why installing php-cli and php-fpm packages ?

It seems frankenphp has php-cli argument to execute cli php files, then installing php-cli seems to be not required.

@pai,

FrankenPHP is still in active development, and while it shows promising features, it’s always best to thoroughly test it in a staging environment before using it in production.
