The editor himself has been in a system read error because of restarting the system by himself, so it can be opened after booting, but there is no interface to enter the account password and start. It made me rely on snapshots all the time.
The following editor will talk about the solution of the editor.
1. df-Th (View mounted directory information)
2. vim /etc/fstab (view system mount read information)
The editor himself has mounted it during the previous installation of httpd, and the original file was deleted, which caused the system to read the /etc/fstab file and read the error, which led to a system error.
Modify (i to modify)
Just delete multiple mount points.
Reboot
is enough to restart.
