Could SELinux or AppArmor be related to this error?

Yes, in some cases, SELinux or AppArmor could be preventing `mysqld` from accessing the `libaio.so.1` library even if it's installed. Check your system logs (e.g., `/var/log/audit/audit.log` for SELinux) for AVC (Access Vector Cache) denials related to `mysqld` and `libaio.so.1`. You might need to adjust SELinux or AppArmor policies to allow access. A temporary workaround (for testing purposes only) is to set SELinux to permissive mode (`sudo setenforce 0`).
