Reset Root Password in CentOs / Redhat Linux | RHCSA

Описание: ​Reboot your system, and interrupt the countdown in bood-loader menu. Edit the default boot- loader entry, in memory, to abort the process just after the kernel mounts all the file system, but before it hands over control to systemd. At the switch_root prompt, remount the /sysroot file system read/write, then use chroot to go into /sysroot. Change the root password to redhat. Configure the system to automatically perform a full SELinux relabel after boot. Reboot your system again and verify the system is working, by logging in as root at the console.Use redhat as the password.

At the end after executing exit, It will take some time depending on the size of your disk and reboots itself.
