CentOS7下，設定網路非常簡單，如果你是ServerGUI的安裝，基本上和windows一樣簡單的設定既可。如果是最小化安裝也可以通過編輯一和設定/etc/sysconfig/network-scripts下面的檔案，然後systemctl restart network既可起效。

設定檔案

 

ifcfg-eth0有的時候實際的名字可能類似於：ifcfg-eno16777736

設定內容例項

[root@host31 network-scripts]# cat ifcfg-eno16777736TYPE="Ethernet"BOOTPROTO
 
="none"DEFROUTE="yes"IPV4_FAILURE_FATAL="no"IPV6INIT="yes"IPV6_AUTOCONF="yes"IPV6_DEFROUTE="yes"IPV6_FAILURE_FATAL="no"NAME="eth0"UUID="9b7e0728-7c25-46e7-b4e1-387ffeb5a66c"DEVICE="eno16777736"ONBOOT="yes"IPADDR="192.168.32.31"PREFIX="24"GATEWAY="192.169.32.2"DNS1="8.8.4.4"IPV6_PEERDNS="yes"IPV6_PEERROUTES
 
="yes"IPV6_PRIVACY="no"[root@host31 network-scripts]#
