Overview

Change the Host Name

The preferred way to change a host name is with hostnamectl as follows:

hostnamectl set-hostname <name>

Example:

hostnamectl set-hostname docker-server.local

This commands changes all the hostnames (static, pretty and transient) of the system.

hostnamectl set-hostname and /etc/hosts


Note that changing the host name with hostnamectl set-hostname does not update /etc/hosts so you may want to review /etc/hosts and change the mapping of the host's network interface addresses to the new name.

If the Name is Publicly Resolved by DNS

TODO http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-hostname.html

/etc/sysconfig/network HOSTNAME

Setting HOSTNAME in /etc/sysconfig/network as shown in the following example

...
NETWORKING=yes
GATEWAY=192.168.0.1
...
HOSTNAME=not500.localdomain

may interfere with network configuration script and change the host name.


This is NOT the preferred way of changing the host name, hostnamectl is.

Setting a Particular Host Name

hostnamectl [--static|--pretty|--transient] set-hostname <name>
