Static host name in Amazon EC2 Linux

Posted on 2013-02-04
Last Modified: 2014-07-25
I have Linux image on Amazon EC2. The problem that I am facing is that when I install Oracle products, they use the private DNS and the next time I would restart the image it will not work.
I would like to setup a permanent host name.
I tried the option of Elastic ip address and the result remain the same.

You need to set up the ORACLE_HOSTNAME environment variable at boot time.

export ORACLE_HOSTNAME=`wget -q -O -` 

add this to your startup script and see if this helps

Thank you very mach.
Before I try quick question: isn't the result of the expression above will result in a different value since the host name is different on every reboot?
Thank you.

If you'll use elastic ip it stays the same after reboot. As well as public hostname.
