centos7下可以生成IPV6和IPV4的网卡配置

如下：

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=f7d4fc7f-2c7b-4363-bbea-c1362bc6bb7b
DEVICE=enp0s3
ONBOOT=yes

如果还是不行就把下面的语句添加到/etc/sysctl.conf里面然后执行sysctl -p

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