Linux 配置静态IP

##前提请确认网络连接方式为：桥接

###修改网卡eth0

vim /etc/sysconfig/network-scripts/ifcfg-eth0 
++++++++++++++++++++++++++++++++
DEVICE="eth0"
BOOTPROTO="static" #将原来的值“dhcp”改为“static”
HWADDR="00:0C:29:F2:4E:96"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="b68b1ef8-13a0-4d11-a738-1ae704e6a0a4"
IPADDR=192.168.1.16    #你需要定义的IP地址
#以下两个的值如果不清楚的话，可以打开你本地的电脑，--》控制面板\所有控制面板项\网络和共享中心\本地连接\详细信息
NETMASK=255.255.255.0 #子网掩码
GATEWAY=192.168.1.1    #默认网关，
++++++++++++++++++++++++++++++++

保存退出
重启网络服务

service network restart

检查一下状态

ifconfig -a
+++++++++++++++++++++++++++++++++

到了这里，请ping一下外网

ping baidu.com

我遇到两个情况：
1）ping通了，oh yeah！
2）报错：ping:unknow host baidu.com好吧，我的解决方法是：dhclient
敲了这个命令后，再ping一次
PING baidu.com (180.149.132.47) 56(84) bytes of data. 　64 bytes from 180.149.132.47: icmp_seq=1 ttl=54 time=38.3 ms 　64 bytes from 180.149.132.47: icmp_seq=2 ttl=54 time=38.7 ms 　64 bytes from 180.149.132.47: icmp_seq=3 ttl=54 time=49.7 ms 　64 bytes from 180.149.132.47: icmp_seq=4 ttl=54 time=38.1 ms 　64 bytes from 180.149.132.47: icmp_seq=5 ttl=54 time=37.9 ms 　64 bytes from 180.149.132.47: icmp_seq=6 ttl=54 time=38.3 ms
　我是这样解决的
还有人是这样：配置静态IP之后reboot

3）还有一个情况就是，ping 外网IP可以，但是无法ping域名。我的解决办法是：设置DNS

vim /ect/resolv.conf
nameserver 114.114.114.114 //这个值我是在本地连接的状态信息里找到的

保存之后退出，再ping！
