You appear to be trying to install both Apache and Nginx on the same server. libapache2-mod-php is only used for Apache while your output indicates you are running nginx. To use php with nginx you’ll want to set up php-fpm. This guide will walk you through the process.
Hello,
The error log you’ve provided indicates that Nginx failed to start because it couldn’t bind to it’s ports. The message listen() to [::]:80, backlog 511 failed (98: Address already in use) implies that there is another process already listening on port 80, which is the standard port for web servers.
You can use the netstat or ss tool to check which process is currently using port 80. Here’s how:
sudo netstat -tuln | grep :80
or
- sudo ss -tuln | grep :80
These commands will give you a list of processes that are using port 80. Look for the PID (Process ID) of the process that’s using port 80.
As said, it’s most probably Apache, to stop Apache, you can run
- sudo systemctl stop apache2
- sudo systemctl disable apache2
Then, you can proceed with the installation/starting of your Nginx service.
