网上大家都在传这个信息，可是很多时候都关不掉只得重装。到官网上看到全面的方法。有效！ vi /etc.sysconfig/networkt NETWORKING_IPV6 no vi /etc/modprobe.conf alias ipv6 off alias net-pf-10 off options ipv6 disable=1 特别是红色部份。关他呢，全加上。reboot 后，ip6 真的去掉了。 Edit /etc/sysconfig/network and set "NETWORKING_IPV6" to "no" For 5.4 and later, replace in /etc/modprobe.conf alias ipv6 off by options ipv6 disable=1 Alternative (which might be easier and works on any release with /etc/modprobe.d): # touch /etc/modprobe.d/disable-ipv6.conf # echo "install ipv6 /bin/true" >> /etc/modprobe.d/disable-ipv6.conf For CentOS 5.3 or older, add the following to /etc/modprobe.conf : alias ipv6 off alias net-pf-10 off Run /sbin/chkconfig ip6tables off to disable the IPv6 firewall
