RockyLinux 9 如何禁用ipv6

查看 RockyLinux 9 的网络配置

 cat  /etc/NetworkManager/system-connections/ens160.nmconnection

ipv6的配置是

[ipv6]
addr-gen-mode=eui64
method=auto

修改 method 为 disabled

[ipv6]
addr-gen-mode=eui64
#method=auto
method=disabled

重启网络

systemctl restart NetworkManager

可以看到已经没有ipv6的配置信息

ifconfig
