centos 启动IPV6

如何在centos系统中启动IPv6功能

1.打开/etc/sysconfig/network
vim /etc/sysconfig/network  

NETWORKING=yes
NETWORKING_IPV6=yes          -----------将NETWORKING_IPV6设置为yes

2. service network restart 重启网络服务
  出现如下错误：

Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
FATAL: Module off not found.
CRITICAL : [ipv6_test] Kernel is not compiled with IPv6 support
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: FATAL: Module off not found.
CRITICAL : [ipv6_test] Kernel is not compiled with IPv6 support [ OK ]
FATAL: Module off not found.
CRITICAL : [ipv6_test] Kernel is not compiled with IPv6 support

解决这个错误，需要修改文件/etc/modprobe.conf,注释掉红色部分的代码

[root@mail ~]# cat /etc/modprobe.conf
alias eth0 tg3
alias scsi_hostadapter ahci
alias scsi_hostadapter1 usb-storage
alias scsi_hostadapter2 3w-9xxx
#alias net-pf-10 off
#alias ipv6 off
#options ipv6 disable=1
alias wlan0 iwlagn
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

3.再次调用service network restart重启网络服务
