The reason is/etc/exports. A folder was previously set as a shared directory, and then the folder was deleted. Therefore, an error will occur when the NFS service is started.
The nonexistent folder needs to be deleted
Find out how to solve it
Use the VI editor to enter/etc/exports

find out whether the corresponding file paths exist in/etc/exports one by one

check and find that there is no exports folder, only the exports file

so use vi to enter the/etc/exports file, delete all

save and exit, Restart NFS successfully
