网卡配置：

vi /etc/sysconfig/network

vi /etc/sysconfig/network-scripts/ifcfg-eth0  （centos7是ifcfg-xxxx）

vi /etc/resolv.conf

DEVICE="ens33"

BOOTPROTO=none

BROADCAST=192.168.0.1

GATEWAY=192.168.0.1

IPADDR=192.168.0.166

NETMASK=255.255.255.0

NM_CONTROLLED="yes"

ONBOOT="yes"

TYPE="Ethernet"

HWADDR=00:0C:29:89:7D:BD

PREFIX=23

DNS1=192.168.0.1

DNS2=114.114.144

DEFROUTE=yes

IPV4_FAILURE_FATAL=yes

IPV6INIT=no

NAME="ens33"

LAST_CONNECT=1422865170

 

centos7.0 没有netstat 和 ifconfig命令问题

执行 

yum install net-tools

  就OK了
