linux配置子接口ipv6地址,CentOS7 设置静态IPv6/IPv4地址

1 环境准备

实验均在Vmware Workstation虚拟机上完成，上网方式选择桥接模式，保证网络支持IPv6,为了操作方便，我们使用root用户登录系统

1.1 Linux系统版本

CentOS Linux release 7.2.1511 (Core)

2

[root@localhost ~]# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

1.2 系统支持IPv6

[root@localhost ~]# ifconfig

eno16777736: flags=4163mtu 1500

inet 49.123.105.124 netmask 255.255.192.0 broadcast 49.123.127.255

inet6 fe80::20c:29ff:fe25:c621 prefixlen 64 scopeid 0x20

inet6 2001:250:4402:2001:20c:29ff:fe25:c621 prefixlen 64 scopeid 0x0

ether 00:0c:29:25:c6:21 txqueuelen 1000 (Ethernet)

RX packets 19255 bytes 2006024 (1.9 MiB)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 2151 bytes 210339 (205.4 KiB)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

如图所示，可以看到系统默认的IPv6地址为2001:250:4402:2001:20c:29ff:fe25:c621

2 修改网络配置文件

根据1.2，我们得知网卡为eno16777736，切换到目录/etc/sysconfig/network-scripts下

1

[root@localhost ~]# cd /etc/sysconfig/network-scripts

编辑文件 ifcfg-eno16777736

[root@localhost ~]# vim ifcfg-eno16777736

IPV6INIT=yes

IPV6_AUTOCONF=no

IPV6_DEFROUTE=yes

DEVICE=eno16777736

ONBOOT=yes

DNS1=202.197.96.1

IPV6ADDR=2001:250:4402:2001:20c:29ff:fe25:8888/64

IPADDR=49.123.105.124

PREFIX=8

GATEWAY=49.123.64.1

3 重启网络

1

[root@localhost network-scripts]# systemctl restart network

4 测试是否配置成功

4.1 通过ifconfig命令查看设置的IPv6/IPv4地址

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 6229 bytes 623829 (609.2 KiB)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

4.2 使用另外一台机器进行ping连接测试(两台机器均在同一局域网内)
