- You need to login to your VestaCP ip address , EX: https://188.8.131.52:8083/ AS 184.108.40.206 is your main server ip
- after that click on the server from the top menu at the right side
3. At the star icon you will see the 'CONFIGURE' word is there click on it
4. There you can type your hostname easily
At the end click on 'save'.
