Linux boots failed with “sulogin: can not open password database” while the /etc/passwd and /etc/shadow files look fine. How to fix this?

Step 2: after Linux booted, disable SELinux following this tutorial.
If it works, it is that SELinux’s permission problem. You may fix them after you have successfully logged on and re-enable SELinux.
Thanks dude. It worked
