Modify the name of the Centos server host.

Modify the name of the Centos server host.
1. Temporarily modify the server host name:

Hostname myhost. The host name specified by myhost.

2. Change the host name permanently.

After the Centos server is installed, the default host name is localhost. localdomain: For convenience and management, we need to modify the server host name. The modification takes effect in two configuration files:/etc/sysconfig/network and/etc/hosts, next we will teach you how to do this:

2.1 Modify/etc/sysconfig/network

Modify hostnamevi/etc/sysconfig/network in/etc/sysconfig/networkHOSTNAME = myhos # modify localhost. localdomain to myhost

2.2 Modify/etc/hosts

Vi/etc/hosts

We can do this after opening:

2.3 restart the server
