Set you linux host name and domain

Recently I have created a new VM linux server on CloudSigma. The Server runs Fedora 22. In order to setup the hostname and network domain I have changed the following files:

[root@illumine ~]# cat  /etc/host
securepdf

[root@illumine ~]# cat /etc/hostname
securepdf

[root@illumine ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

178.XXX.XXX.132   securepdf.illumineit.com securepdf

Test it using ping:

[root@securepdf ~]# ping securepdf

PING securepdf.illumineit.com (178.XXX.XXX.132) 56(84) bytes of data.

64 bytes from securepdf.illumineit.com (178.XXX.XXX.132): icmp_seq=1 ttl=64 time=0.036 ms
