ONBOOT=yes

IPADDR =192.168.160.11

NETMASK=255.255.255.0

Modify hostname

[root@localhost ~] #vi /etc/sysconfig/network

[root@localhost ~]# cat /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME =leekwen.leekwen

[root@localhost ~]# ifconfig eth0

[root@localhost ~]# vi /etc/resolv.conf

[root@localhost ~ ]# cat /etc/resolv.conf

search localdomain

nameserver 192.168.160.1

nameserver 202.101.172.46
