Forget the Linux login password, root is not the previous 123456, change the root password login

Mine is CentOS 7 running under VMware.

When entering

Press e-and then scroll through the list to find the Ro (next to root), replace it with RW, space and add init=/sysroot/bin/sh,

Then press Ctrl+x to enter into single user mode, in this mode, you can change the password

Run Chroot/sysroot First
:/#chroot/sysroot

Last run passwd ROOT to set a new password
:/#passwd Root

Run touch/.autorelabel to update selinux parameters after setting the password

After that, direct VMware restarts the client and reboots.

And then log in just fine.
