Linux CentOs6.4 静态IP 设置
To do that, just log on as root and change directory to /etc/sysconfig/network-scripts/ to view all available devices.
# cd /etc/sysconfig/network-scripts/
You need to edit following files:
- /etc/sysconfig/network-scripts/ifcfg-eth0 : First Ethernet card configuration file
- /etc/sysconfig/network-scripts/ifcfg-eth1 : Second Ethernet card configuration file
To edit/create first NIC file, type command:
# vi ifcfg-eth0
Append/modify as follows:
DEVICE=eth0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:30:48:56:A6:2E
IPADDR=192.168.0.10
NETMASK=255.255.255.0
ONBOOT=yes
Save and close the file.
After that, configure the default gateway (router IP) and hostname in /etc/sysconfig/network file:
# vi /etc/sysconfig/network
Append/modify configuration as follows:
NETWORKING=yes
HOSTNAME=techkaki
GATEWAY=192.168.0.1
Save and close the file. Restart networking by enter following command:
# /etc/init.d/network restart
Make sure you have correct DNS server defined in /etc/resolv.conf file:
# vi /etc/resolv.conf
Setup DNS Server as follows:
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 202.67.222.222
Save and close the file. Now you can ping the gateway/other hosts:
$ ping 192.168.0.1
