Additional Notes
Display Manager: By default, CentOS 7 uses GDM (GNOME Display Manager) for the login screen. Other display managers like LightDM can also be installed and configured if desired.
Desktop Environment: If GNOME isn't your preferred desktop environment, you can install other options like KDE Plasma or Xfce instead of GNOME.
Enabling GUI on CentOS 7 can make the system more approachable for users who are accustomed to graphical interfaces. However, keep in mind that running a GUI on a server can consume more resources compared to a minimal installation, so it's essential to consider the trade-offs based on your system's use case.
With these steps, you can easily set up a GUI environment on your CentOS 7 server to accommodate your workflow preferences.
