  • debian12 最小化安装后,配置静态ip

    debian12 最小化安装后,配置静态ip

    配置静态ip

    1. 检查那个网口是配置好线路的.
    2. 给目标网口配置ip
    root@debian:~# cat  /etc/network/interfaces.d/ifcfg-enp59s0f0
auto enp59s0f0
iface enp59s0f0 inet static
    address 192.168.11.53
    netmask 255.255.248.0
    gateway 192.168.8.254
    1. 重启网络
    systemctl restart networking.service
    1. 检查ip
    root@debian:~# ip addr

    如果新安装的debian 可能没有安装 resolvconf, 无法解析域名.

    这个时候可以先在别的机器测试mirrors.aliyun.com的ip是多少,然后配置到 /etc/hosts

    root@debian:~# grep mirror /etc/hosts
218.77.200.227 mirrors.aliyun.com
root@debian:~#

    安装resolvconf

    apt update
apt install resolvconf

    配置dns解析

    root@debian:~# cat /etc/resolvconf/resolv.conf.d/base
nameserver 114.114.114.114
root@debian:~#

    重启resolveconf

    systemctl restart resolvconf

    配置zh_CN.utf8

    # 查看可以使用的编码
root@debian:~# locale -a
C
C.utf8
en_HK.utf8
POSIX
root@debian:~#

# 增加zh_CN.utf8 编码
dpkg-reconfigure locales
# 选择zh_CN.utf8,然后ok回车.

# 再次查看
root@debian:~# locale -a
