Question

I did not name my droplet s the same as my domain name

  • Posted April 19, 2014

I made a mistake and did not name my droplet s the same as my domain name. I then brought up my web server and set up DNS to my domain name. All’s well with webserver.

I now want to install a mail server and it says to name my droplet the same as my domain name, which will become its hostname and reverse DNS record. https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-04-x64

Can I fix this some how without starting a new droplet and reassigning the new IP to my domain name.

Definitely. Edit <code>/etc/hostname</code> and replace the contents with your new hostname. Also edit <code>/etc/hosts</code> and add the following line: <br><pre>127.0.0.1 newhostname.com newhostname</pre> <br> <br>Finally, run <pre>sudo hostname -F /etc/hostname</pre>

You can change the domain name of your droplet in the Settings->Rename tab.
