Centos 7禁用关闭IPv6的方法

1.在/etc/sysctl.conf中添加此规则:

net.ipv6.conf.all.disable_ipv6 = 1

2.在/etc/sysconfig/network中添加此规则:

NETWORKING_IPV6 = no

3.在/etc/sysconfig/network-scripts/ifcfg-ethX中添加此规则:

IPV6INIT = no

4.关闭防火墙的开机自启动服务:

systemctl disable ip6tables.service

5.重新加载sysctl配置或者重启服务器

#sysctl -p
or
#reboot

注:

在/etc/sysconfig/network-scripts/ifcfg-ethX中ethX为网卡名

示例:

centos7ipv6

vi /etc/sysctl.conf
vi /etc/sysconfig/network
vi /etc/sysconfig/network-scripts/ifcfg-eth0

此答案有用么?
