Issue Problem and Question to ibdata1

Hello, I’m having an issue on an AlmaLinux 8.10 server with 10 subscriptions (10 domains, some of which use WordPress) where the disk space is getting smaller every day. I’m already getting warning messages, so I took a look: the ibdata1 file in /var/mysql is 66 GB. The databases for the individual domains are actually stored in their own databases. So what’s causing the ibdata1 file to grow so much? Can I view it directly on the server using phpMyAdmin? And most importantly, how can I reduce the size of the file again?
