04-CentOS开启IPv6

1、修改disable_ipv6.conf

vi /etc/modprobe.d/disable_ipv6.conf

options ipv6 disable=0

2、修改network配置

vi /etc/sysconfig/network

NETWORKING_IPV6=yes

3、修改网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-eth0

IPV6INIT=yes
IPV6_AUTOCONF=yes

4、修改sysctl.conf

vi /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0

sysctl -p

5、创建系统在启动时自动加载 IPv6 模块的脚本

vi /etc/sysconfig/modules/ipv6.modules

#!/bin/sh
if [ ! -c /proc/net/if_inet6 ] ; then
exec /sbin/insmod /lib/modules/uname -r/kernel/net/ipv6/ipv6.ko
fi

6、加载 IPv6 模块

ifconfig | grep -i inet6
查看ipv6的信息，有看到输出就可以
