My installation RAM 2GB and HardDisk 50GB.
If your want to change your hostname.
[root@Cloud-technologyrss:~]# vi /etc/hosts
Insert your choose-able host name. Open another file insert host name.
[root@Cloud-technologyrss:~]# vi /etc/hostname
Configure static IP on centos 6.5. Make sure your machine connected on LAN eth0 or eth1. So you can setup static ip any LAN.
Open static ip config file via any editor.
[root@Cloud-technologyrss:~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
Insert below line then save config file and service restart.
DEVICE=eth0 HWADDR=C2:EE:64:E4:75:E2 TYPE=Ethernet UUID=45801e43-18d4-474b-8b4f-0c365ef520fd ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=10.20.40.80 NETMASK=255.255.0.0 GATEWAY=10.20.40.1 DNS1=4.2.2.2
Then run restart command
[root@Cloud-technologyrss:~]# service network restart
Test your internet connection.
[root@Cloud-technologyrss:~]# ping 8.8.8.8
You can see all ping is ok.
If you can’t enable ping then open resolv.conf file insert google public name sever.
[root@Cloud-technologyrss:~]# vi /etc/resolv.conf
nameserver 4.2.2.2
Again test ping.
Thanks to all.
