虚拟机centos静态配置IP

修改三个文件：

/etc/sysconfig/network

/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/resolv.conf

1，/etc/sysconfig/network

[root@localhost ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
GATEWAY=192.168.123.254
HOSTNAME=localhost.localdomain

2,/etc/sysconfig/network-scripts/ifcfg-eth0

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82540EM Gigabit Ethernet Controller
#DEVICE=eth0
#BOOTPROTO=dhcp
#ONBOOT=yes
#HWADDR=08:00:27:fd:b1:9c

DEVICE=eth0
BOOTPROTO=static
TYPE=Ethernet
#NAME="System eth0"
BROADCAST=192.168.123.255
HWADDR=08:00:27:fd:b1:9c
IPADDR=192.168.123.102
#IPV6INIT=yes
#IPV6_AUTOCONF=yes
NETMASK=255.255.255.0
#NETWORK=192.168.123.254
ONBOOT=yes

3,/etc/resolv.conf DNS配置

[root@localhost ~]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 192.168.123.254  
search localdomain

 

OK，省去了每次xshell连接时须修改IP的麻烦
