- Edit /etc/default/grub and add ipv6.disable=1 in line GRUB_CMDLINE_LINUX, e.g.:
在GRUB_CMDLINE_LINUX后面添加ipv6.disable=1
# cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="ipv6.disable=1 crashkernel=auto rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
- Regenerate a GRUB configuration file and overwrite existing one:
grub2-mkconfig -o /boot/grub2/grub.cfg
- Restart system and verify no line “inet6” in “ip addr show” command output.
# shutdown -r now
# ip addr show | grep net6
