Change the root password

I am new to RedHat. Last week, I just know to change the root password in RH Linux is easier than window system. For Windows, you may need the ERD. For RH, just boot to single user mode.

Method 1. Run init1 (but init must be superuser)

Method 3. Boot RH installation Disk and run linux rescue mode

passwd
