问题
默认情况下，CentOS 6安装没有网络接入相关配置，需要你对网络接口进行配置。
解决方案

查看缺省接口配置

接口相关配置保存在/etc/sysconfig/network-scripts目录下，下面显示的是缺省的接口配置。

[root@CentOS65 network-scripts]# more /etc/sysconfig/network-scripts/ifcfg-eth0   DEVICE=eth0  HWADDR=00:0C:29:C1:48:03  TYPE=Ethernet  UUID=b2bbb718-caa6-46c3-ae12-587cbedfd5fa  ONBOOT=no  NM_CONTROLLED=yes  BOOTPROTO=dhcp

配置接口静态地址

# vi /etc/sysconfig/network-scripts/ifcfg-eth0  DEVICE=eth0TYPE=EthernetUUID=ba6db3a7-4921-414a-ad19-32f1ba035c03ONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=noneIPADDR=192.168.200.122PREFIX=24GATEWAY=192.168.200.1DNS1=192.168.200.13DNS2=192.168.200.14DOMAIN=wlyd.localDEFROUTE=yesIPV4_FAILURE_FATAL=yesIPV6INIT=no

配置网关

# vi /etc/sysconfig/network  NETWORKING=yesHOSTNAME=RD-CD-APP122.wlyd.localGATEWAY=192.168.200.1

重启网络接口

[root@CentOS65 network-scripts]# /etc/rc.d/init.d/network restart  Shutting down interface eth0:  [  OK  ]  Shutting down loopback interface:  [  OK  ]  Bringing up loopback interface:  [  OK  ]  Bringing up interface eth0:  Determining if ip address 192.168.200.122 is already in use for device eth0...  [  OK  ]

配置DNS服务器

# vi /etc/resolv.conf  nameserver x.x.x.x # Replace with your nameserver ip  nameserver y.y.y.y # Replace with your nameserver ip

查看接口配置
使用”ip a”或ifconfig命令可以查看当前接口配置信息
