=====Reset the Root Password===== To access that root shell, follow these steps: Reboot the system. * Interrupt the boot-loader countdown by pressing any key, except Enter. * Move the cursor to the rescue kernel entry to boot (the entry with the rescue word in its name). * Press e to edit the selected entry. * Move the cursor to the kernel command line (the line that starts with linux). * Append **rd.break**. With that option, the system breaks just before the system hands control from the initramfs image to the actual system. * Press Ctrl+x to boot with the changes. * Press Enter to perform maintenance when prompted. To reset password you need to: * Remount /sysroot as read/write. mount -o remount,rw /sysroot * Switch into a chroot jail, where /sysroot is treated as the root of the file-system tree. chroot /sysroot * Set a new root password. passwd root * Ensure that all unlabeled files, including /etc/shadow at this point, get relabeled during boot. touch ./autorelabel * type exit twice this can take a while other option is to use load_policy -i this causes Selinux policy to be loaded and now we can use Selinux commands restorerecon -FvR /etc/shadow This relabels /etc/shadow correctly. You can exit the server and reboot as it will start to generate errors when making changes to grub you need to edit the **/etc/default/grub** once you are done you need to regenerate the grub config file grub2-mkconfig -o /boot/grub2/grub.cfg
