How to change hostname for my VPS?

Gmeister4 · Jul 4, 2016

I tried this way

Code:

sudo nano /etc/sysconfig/network

and in this file I changed

Code:

HOSTNAME=myserver.domain.com

but when I check with hostname -f , it is still not getting right hostname that I wanted.

Do you guide me how to change hostname for my VPS completely?

If Nano is installed on your server, you might use this additional way

Using this command

nano /etc/hosts

Change to something like this

For example

105.197.10.132 server.yourdomain.com

In the line above, 105.197.10.132 is your IP address

Hope it helps!

# Run the hostname command:
hostname HOST_NAME

# Open /etc/sysconfig/network, update the HOSTNAME line and save:

# vim /etc/sysconfig/network OR # nano /etc/sysconfig/network
HOSTNAME=HOST_NAME

# Open your hosts file, and update the hostname entry and save:
vim /etc/hosts OR nano /etc/hosts
127.0.0.1 HOST_NAME

hostname NEW_NAME, for redhat, this is set using the init script /etc/rc.d/rc.sysinit

/etc/sysconfig/network
HOSTNAME="xx.domain.xxx"

#hostname "yourhostname"

This will change the host name on a Linux server

And be careful because Redhat/Centos doesn't work the same than Debian/Ubuntu

With Centos your hostname should be a FQDN like server.yourdomain.com when on debian your will add in /etc/hosts

Code:

188.165.55.XX server.yourdomain.com server

But in /etc/hostname, you should use only "server" and not server.yourdomain.com

The best tutorial I have found for that is in iRedMail documentation :

Centos : http://www.iredmail.org/docs/install.iredmail.on.rhel.html

Debian : http://www.iredmail.org/docs/install.iredmail.on.debian.ubuntu.html

Is it necessary to add server end of line?

I remember I failed once when add this to end of line in /etc/hosts

I filled full hostname as server.yourdomain.com

I'm sorry if this sounds dumb, but is the hostname the ip? Lol sorry just started a vps and didn't really know what it was.

You can use anything to replace server, but a Fully Qualified Domain Name (FQDN) have to be a subdomain because it reveal all the domain authority of your domain.

The hostname is the name associated with the IP of the server.

With a correct setup the hostname IP should have a A record like server.yourdomain.com -> YOUR.SERVER.IP and also a reverse to resolve YOUR.SERVER.IP -> server.yourdomain.com

Change in /etc/sysconfig/network and enter in the file HOSTNAME=server.example.com and reboot your VPS . Reboot once.
This will change it permanently

You should actually see if your VPS provider has a VPS control panel to manage your VPS from as you can usually set the VPS hostname there and it will hardcode it to your VPS.

Hello,

You should have to reboot the dedicated server or vps once you changed the hostname in /etc/sysconfig/network and its a permanent change. Also, changing the hostname with hostname command is temporary change.
