2．确认系统是否支持IPv6，显示0表示应支持

[root@localhost ~]# sysctl -a | grep ipv6.*disable

net.ipv6.conf.all.disable_ipv6 = 0

net.ipv6.conf.default.disable_ipv6 = 0

net.ipv6.conf.lo.disable_ipv6 = 0

net.ipv6.conf.eth0.disable_ipv6 = 0

如果显示为1，可以修改/etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 0

net.ipv6.conf.default.disable_ipv6 = 0

net.ipv6.conf.lo.disable_ipv6 = 0

net.ipv6.conf.eth0.disable_ipv6 = 0

然后重载配置文件/etc/sysctl.conf 使文件内容生效

sysctl -p

再次输入ifconfig查看系统已支持IPv

3．配置IPv6地址，用vi等编辑器打开

/etc/sysconfig/network-scripts/ifcfg-eth0，添加以下三行：（注：红色部分根据实际情况进行修改。）

IPV6INIT=yes----初始化IPv6地址

IPV6ADDR=2400:a480:f:413:116:255:249:39----填写服务器IPv6地址。

IPV6_DEFAULTGW=2400:a480:f:413::1----填写服务器IPv6网关。

添加完之后，输入:wq 保存退出。

重启网络服务，输入命令：service network restart

添加IPv6 DNS，用vi等编辑器打开/etc/resolv.conf，添加以下一行：

nameserver 2001:da8:202:10::37

添加完之后，输入:wq 保存退出。
