Debian系统中将动态ip改为静态ip
安装debian时,在安装过程中会默认启用dhcp获取网络地址,但为了管理方便,我希望使用静态ip,这样就能保持ip固定。在debian系统中配置静态ip地址,涉及到2个文件要修改,具体操作如下。
1、配置静态ip:
vi /etc/network/interfaces
可以看到默认是dhcp配置:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
看到上面的最后一行没?这里需要将dhcp改为static,并配置指定的ip地址,具体如下:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 10.248.201.224/23
gateway 10.248.201.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 10.248.201.8
2、修改DNS,编辑/etc/resolv.conf中的nameserver
vi /etc/resolv.conf
nameserver 10.248.201.8
nameserver 114.114.114.114
修改完成后,重启网络使配置生效:
systemctl restart networking
或者重启系统也可以。
