Every time I reboot the vps, it comes as hostname “defaulthostname”. How to prevent this?
1. You can change its hostname with the command ‘hostname‘
# hostname
without parameter it will output the current hostname.
# hostname your-hostname
will set the hostname of the system to your-hostname
2. Login to SSH as root and navigate to etc/sysconfig then type: chattr +i network.
cd ..
cd etc/sysconfig
chattr +i network
