Centos7 添加 IPV6 地址
前言
大家应该买过含IPV6地址的服务器,或者多个IPV4地址的服务器,但是有的商家不会自动绑定,需要我们手动绑定.
例如Buyvm和OVH
正文
临时添加
ip -6 addr add 2605:6400:0020:130d::2/64 dev eth0
使用ifcongfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet xxx.xxx.xxx.xxx netmask 255.255.255.0 broadcast 205.185.121.255
inet6 2605:6400:20:130d::2 prefixlen 64 scopeid 0x0<global>
inet6 fe80::216:45ff:fe97:af56 prefixlen 64 scopeid 0x20<link>
inet6 2605:6400:20:130d:: prefixlen 128 scopeid 0x0<global>
ether 00:16:45:97:af:56 txqueuelen 1000 (Ethernet)

TX packets 90533440 bytes 747906361963 (696.5 GiB)

可以发现已经绑定上了
永久添加
首先使用ifconfig
查看网卡信息
docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 172.17.0.1 netmask 255.255.0.0 broadcast 0.0.0.0
ether 02:42:8d:3b:c1:b2 txqueuelen 0 (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
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet xxx.xxx.xxx.xxx netmask 255.255.255.0 broadcast 205.185.121.255
inet6 fe80::216:45ff:fe97:af56 prefixlen 64 scopeid 0x20<link>
ether 00:16:45:97:af:56 txqueuelen 1000 (Ethernet)

RX errors 0 dropped 7 overruns 0 frame 0
TX packets 90509939 bytes 747690271954 (696.3 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
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 1000 (Local Loopback)
RX packets 66726308 bytes 30552961591 (28.4 GiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 66726308 bytes 30552961591 (28.4 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
从中可以看到eth0
为主网卡,目前绑定的IPV6为fe80::
即内网地址
之后切换到/etc/sysconfig/network-scripts
文件夹
修改对应得配置文件,在最后添加:
IPV6INIT=yes
DNS1=1.1.1.1
DNS2=2a06:98c1:54::bc6
DNS3=2001:4860:4860::8888
IPV6ADDR=2605:6400:0020:130d:0000:0000:0000:0000
之后systemctl restart network
重启网络
