Archlinux设置静态固定IP

最近装了Archlinux，可是每次开机后，设置的IP都没有了，废了好大劲才搞定，俗话说好记性不如烂笔头，特意摘录下来，已备后需。

首先 ifconfig -a 查看自己的网卡，如下

[root@localhost /]# ifconfig -a

enp0s25: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

ether 3c:97:0e:78:6f:c8 txqueuelen 1000 (Ethernet)

RX packets 205 bytes 22491 (21.9 KiB)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 129 bytes 39400 (38.4 KiB)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

device interrupt 20 memory 0xf3a00000-f3a20000

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

inet 127.0.0.1 netmask 255.0.0.0

inet6 ::1 prefixlen 128 scopeid 0x10<host>

loop txqueuelen 0 (Local Loopback)

RX packets 0 bytes 0 (0.0 B)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 0 bytes 0 (0.0 B)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

wlp3s0: flags=4098<BROADCAST,MULTICAST> mtu 1500

ether 9c:4e:36:a3:5a:2c txqueuelen 1000 (Ethernet)

RX packets 0 bytes 0 (0.0 B)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 0 bytes 0 (0.0 B)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

由此可以看出，第一块网卡是enp0s25，我们对其进行设置，故在/etc/netctl 下新建文件 enp0s25，并对其进行编辑:

[root@localhost /]# cd /etc/netctl/

[root@localhost /]# nano enp0s25

将其内容修改如下：

Description='enp0s25'
Interface=enp0s25
Connection=ethernet
IP=static
Address=('192.168.0.14/24')
#Routes=('192.168.0.0/24 via 192.168.0.1')
Gateway='192.168.0.1'
DNS=('192.168.0.1')
TimeoutUp=300
TimeoutCarrier=300

之后使用命令netctl其生效，

[root@localhost /]# netctl
enable enp0s25

重启Archlinux即可

[root@localhost /]# reboot

效果如下：



可见设置生效。
