How to create custom /etc/resolv.conf?

You may notice that everytime you reboot your VPS, the changes you made on your /etc/resolv.conf file is being replaced with the default settings. This is common to OpenVZ technology because it uses scripts that when a container is rebooted, it replaces all the config files to the default for security reasons.

The workaround so that your /etc/resolv.conf won't get replaced each reboot occurence are the following.

Before anything else, make a backup of all your changes to resolv.conf and place it somewhere like "/backup" directory.

Workaround 1: Open your /etc/rc.local and add one of the two commands below.

cp /backup/resolv.conf /etc/resolv.conf


OR

echo 'nameserver 4.4.8.8' > /etc/resolv.conf


(4.4.8.8 is only an example)


Workaround 2: Create a startup script and use "@reboot" crontab command (it will execute your script only after reboot)

Key in:

#export EDITOR=nano
#
crontab -e


Then add:

@reboot cp /backup/resolv.conf /etc/resolv.conf


Both workarounds will replace your resolv.conf each reboot occurence so that your changes are preserved even OpenVZ replaces them. Hope this helps!
