How to Properly Shutdown Linux CentOS/RHEL Server

Properly shutting down your Linux system is important to avoid potential data loss, filesystem corruption, and to ensure a clean startup the next time you use the system.

In this short guide, we will discuss different methods to properly shutdown a Linux system using the command line.

The command line offers several commands to safely shutdown your Linux system. Here are some common options:

Option 1: Use the shutdown Command

To schedule a system shutdown, you can use the shutdown command followed by a time parameter. To shutdown the system immediately, run:

sudo shutdown now

If you want to shutdown the system after a specific time period (e.g., 10 minutes), use the following command:

sudo shutdown +10

Option 2: Use the poweroff Command

An alternative command to shutdown the system immediately is poweroff. Execute the following command:

sudo poweroff

Option 3: Use the halt Command

Another command to shutdown the system is halt. By default, the halt command only stops the system but does not power it off. To power off the system with the halt command, run:

sudo halt -p

Commands Mentioned:

  • sudo shutdown now – Shuts down the system immediately.
  • sudo shutdown +10 – Schedules a system shutdown after 10 minutes.
  • sudo poweroff – Shuts down and powers off the system immediately.
  • sudo halt -p – Shuts down and powers off the system using the halt command.
