Linux如何设置IPv6

本教程仅适用于在产品中存在 ipv6 地址，并且没有被自动分配的情况。

‍

首先检查本地 ip，并检查 /etc/network/interfaces 文件中是否存在 ipv6 相关配置

shell

# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether e2:5e:d7:00:01:6f brd ff:ff:ff:ff:ff:ff
    inet 183.131.51.90/24 brd 183.131.51.255 scope global eth0
       valid_lft forever preferred_lft forever

# cat /etc/network/interfaces
auto lo
iface lo inet loopback
    dns-nameservers 223.5.5.5
    dns-search local

auto eth0
iface eth0 inet static
    address 183.131.51.90	#这是你的ip
    netmask 255.255.255.0	#掩码
    gateway 183.131.51.1    #网关

如执行 ip a 查看没有 ipv6 地址，且/etc/network/interfaces 中没有 v6 相关配置，则可以对 ipv6 设置进行手动添加

shell

# nano /etc/network/interfaces

进入文本编辑界面后，并在末尾添加如下内容

text

iface eth0 inet6 static
    address 240e:f7:a020:204::4ec4/112	#系统中分配的ip
    gateway 240e:f7:a020:204::1			#对应网关

添加完成后，您可以按 Ctrl+x 退出，退出时输入 y 同意写入到文件

不要修改文件名，直接按回车继续

再次查看文件确认配置无误后，即可重新加载网络配置，最后确认是否已经可以访问 ipv6

shell

# cat /etc/network/interfaces
auto lo
iface lo inet loopback
    dns-nameservers 223.5.5.5
    dns-search local

auto eth0
iface eth0 inet static
    address 183.131.51.90
    netmask 255.255.255.0
    gateway 183.131.51.1

iface eth0 inet6 static
    address 240e:f7:a020:204::4ec4/112
    gateway 240e:f7:a020:204::1
# service networking.service reload

# ip a | grep inet6
    inet6 240e:f7:a020:204::4ec4/112 scope global
    inet6 fe80::e05e:d7ff:fe00:16f/64 scope link
# ping -6 -c 4 www.baidu.com

至此你已经完成了 ipv6 的手动配置！
