Solution:

1. Switch to superuser

[test@test ~]$ su -

Password:

2 View host name

[root@test ~]# hostname

test

3. Enter the following command

[root@test ~]# echo ‘127.0.0.1 test.localdomain test’ 》 /etc/hosts

This means that the host hostname is consistent with the query. After this command is executed, using sudo again will respond immediately.
