I have several amazon ec2 instances running Linux AMIs based on Fedora and even though I set the hostname using the command:

hostname example.com

whenever I have to reboot any of them this hostname gets reset to something ip***, how can I make my hostname stick and make it permanent??

Open this /etc/sysconfig/network:

  • There will be HOSTNAME attribute. Change there for a permanent change.
