Kindly change the hostname through Change Hostname option in CWP admin panel.

there are couple of places to specify the hostname. You may run a meta search for that string in question and see where it pops up and adjust accordingly.

Code: [Select]

grep --exclude-dir={boot,dev,media,mnt,proc,run,sys,root} -rnw '/' -e "server1"

more refined search, yielding less results. it may take a few minutes to complete the searcch

Code: [Select]

grep --exclude-dir={boot,dev,media,mnt,proc,run,sys,root,var,postfix,dovecot,lvm} -rnw '/' -e "server1"

The most likely places where the hostname is stipulated are

Quote

/etc/hosts
/etc/hostname

Ok I sorted out the http test I accidentally changed the shared IP

But still sorting out host name

/etc/hosts
This does not change until I update the hostname from the web interface

Code: [Select]

127.0.0.1 localhost.localdomain localhost
# Auto-generated hostname. Please do not remove this comment.
123.123.123.123 server1.domain.com  server1
::1 localhost
/etc/hostname
This does change when I update or restart
that is what I change it to

Code: [Select]

server1.domain.comafter reboot

Code: [Select]

server1

I am thinking I am getting confused between fqdn and hostnames but still not sure how to sort it out

Title: Re: Hostname changes on every reboot

I did some research on this problem and I have sort it out by locking the hostname file and I just did hosts aswell just incase I think its the hosting provider that did this but here i used this code.

To lock

Code: [Select]

chattr +i /etc/hosts /etc/hostname
To unlock

Code: [Select]

chattr -i /etc/hosts /etc/hostname
If there is a problem with this to cwp please some one let me know thank you

Good that you figured it out and shared your solution! The hosting provider though should not interfere in such manner after the installation of the server completed...
