rhel5之禁用IPv6模块

 

禁用前如下所示：

[root@server5 ~]# ip -6 addr list
1: lo: mtu 16436
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: mtu 1500 qlen 1000
    inet6 fe80::20c:29ff:fe58:9849/64 scope link
       valid_lft forever preferred_lft forever
[root@server5 ~]# ip addr list
1: lo: mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:0c:29:58:98:49 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.15/24 brd 192.168.1.255 scope global eth0
    inet6 fe80::20c:29ff:fe58:9849/64 scope link
       valid_lft forever preferred_lft forever
3: sit0: mtu 1480 qdisc noop
    link/sit 0.0.0.0 brd 0.0.0.0

修改/etc/modprobe.conf文件，加入以下两行:

alias net-pf-10 off

alias ipv6 off

保存，退出，重启机器后，如下所示：

[root@server5 ~]# ip -6 addr list
[root@server5 ~]#

无相关IPv6的信息输出，则禁用IPv6模块成功！！！
