1. Check SSH server status:
#service sshd status
If installed and running, the output should resemble:
“sshd (pid 9488 9486 1850) is running...”
If not installed, use the following command to install and start SSH server:
#yum install -y openssh openssh-server openssh-clients openssl-libs && service sshd start
2. Edit SSH configuration to enable root login:
#vi /etc/ssh/sshd_config
Find the line:
#PermitRootLogin without-password
Remove ‘#’ and change ‘without-password’ to ‘yes’:
PermitRootLogin yes
Save the file:
Press "ESC", type :wq (or :x), and hit/press "ENTER"
3. Restart SSH service:
#service sshd restart
Quick Guide Commands:
Check sshd status: #service sshd status Install sshd: #yum install -y openssh openssh-server openssh-clients openssl-libs Start sshd: #service sshd start Stop sshd (be cautious when running this command): #service sshd stop Reload sshd: #service sshd reload
If you find the process complicated or feel insecure, you can request assistance from our system admins to enable or disable root login through SSH on your CentOS server.
