本文详细介绍了如何在Linux系统中通过编辑系统配置文件来设置静态IP地址，包括添加网关、更新DHCP为静态配置、配置DNS服务器以及验证配置效果等步骤。

step1: add gateway
vi /etc/sysconfig/network
add below "GATEWAY" line
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
[b]GATEWAY=192.168.1.1[/b]

step2: add your new IP address
update dhcp to static,
add your ipaddr line
add your netmast line

DEVICE=eth0
#BOOTPROTO=dhcp
[b]BOOTPROTO=static[/b]
HWADDR=00:CC:23:3A:C3:EF
[b]IPADDR=192.168.1.200
NETMAST=255.255.255.0[/b]
ONBOOT=yes

step3: update name server
vi /etc/resolv.conf
nameserver x.y.z.p
(normal, below step won't need, cause it will automaticlly get your name server)

step4:verify the static ip config effect:
ifconfig eth0
