Enable root login – CentOS / Redhat / Almalinux / Rockylinux

Enable root login over SSH:

As root, edit the sshd_config file in /etc/ssh/sshd_config:
```
nano /etc/ssh/sshd_config
```
Add a line in the Authentication section of the file that says PermitRootLogin yes. This line may already exist and be commented out with a “#”. In this case, remove the “#”.
```
# Authentication:
#LoginGraceTime 2m
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
```
Save the updated /etc/ssh/sshd_config file.
Restart the SSH server:
```
service sshd restart
```

You can now connect to the conversion server as root over SSH.
