如何配置CentOS的静态IP地址

发表于 通过

以下步骤将为 CentOS 配置静态 IP 地址.

  1. Check the network interface that you would like to set the static IP address on. 
    ip addr

    Linux Network Interface Output

  2. Here we are setting network interface enp0s8 to be static. We need to edit the corresponding file in the path /etc/sysconfig/network-scripts . The file for interface enp0s8 是 ifcfg-enp0s8 .

    sudo nano ifcfg-enp0s8
  3. The file needs to be changed from the following 
    NAME="enp0s8"
DEVICE="enp0s8"
ONBOOT=yes
NETBOOT=yes
UUID="9ca41371-ee2d-4061-ab44-30bc06df3076"
IPV6INIT=yes
BOOTPROTO=dhcp
TYPE=Ethernet

    Change the above to the following to make the interface use a static IP address. Additions are in green and amendments are in amber.

    IPADDR=192.168.56.222
NETMASK=255.255.255.0
GATEWAY=192.168.56.1
NAME="enp0s8"
DEVICE="enp0s8"
ONBOOT=yes
NETBOOT=yes
UUID="9ca41371-ee2d-4061-ab44-30bc06df3076"
IPV6INIT=yes
BOOTPROTO=static
TYPE=Ethernet

    Press Ctrl + X to save the file
