静态IP配置

在Arch Linux上配置静态IP有两种方式

netctl配置静态IP

netctl是命令行工具，可以控制systemd的network profile manager。

  • 在arch linux的 /etc/netctl/examples/ 目录下存储了配置案例，可以复制出来作为修改的起始基础
sudo cp /etc/netctl/examples/ethernet-static /etc/netctl/enp0s3
  • 修改配置 /etc/netctl/enp0s3
Description='A basic static ethernet connection'
Interface=enp0s3
Connection=ethernet
IP=static
Address=('192.168.1.102/24')
Gateway=('192.168.1.1')
DNS=('8.8.8.8' '8.8.4.4')
  • 激活网卡以便每次启动系统时激活
sudo netctl enable enp0s3
  • 启动网卡接口
sudo netctl start enp0s3
  • 停止dhcp服务
sudo systemctl stop dhcpcd
sudo systemctl disable dhcpcd
  • 重启系统后通过以下命令检查
ip addr

使用systemd配置静态IP

也可以通过systemd配置金泰IP地址

  • 编辑 /etc/systemd/network/enp0s3.network
[Match]
Name=enp0s3

[Network]
Address=192.168.1.102/24
Gateway=192.168.1.1
DNS=8.8.8.8
DNS=8.8.4.4
  • 然后需要关闭netctl，需要找到和netctl相关的激活配置，执行以下命令
sudo systemctl list-unit-files

例如

sudo systemctl disable [email protected]
  • 删除netctl软件包
sudo pacman -Rns netctl
  • 停止dhcp服务
sudo systemctl stop dhcpcd
sudo systemctl disable dhcpcd
  • 然后激活systemd-networkd服务
sudo systemctl enable systemd-networkd
sudo systemctl start systemd-networkd

使用netctl配置动态IP地址

  • 首先安装netctl
sudo pacman -S netctl
  • 复制配置案例
sudo cp /etc/netctl/examples/ethernet-dhcp /etc/netctl/enp0s3
  • 然后修订配置 /etc/netctl/enp0s3
Description='A basic dhcp ethernet connection'
Interface=enps03
Connection=ethernet
IP=dhcp
#DHCPClient=dhcpcd
#DHCPReleaseOnStop=no
## for DHCPv6
#IP6=dhcp
#DHCP6Client=dhclient
## for IPv6 autoconfiguration
#IP6=stateless
  • 启动dhcpcd服务
sudo systemctl enable dhcpcd
sudo systemctl start dhcpcd
