Centos6/7 網絡卡配置 以及踩坑例項
網絡卡配置：
vi /etc/sysconfig/network
vi /etc/sysconfig/network-scripts/ifcfg-eth0 （centos7是ifcfg-xxxx）
vi /etc/resolv.confDEVICE="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 沒有netstat 和 ifconfig命令問題
執行
yum install net-tools就OK了
