Hello please help.
I am install OpenVPN on Linux and install tun device, but tap device or driver is not install.
I am enter following command:

[root@hhh tun-1.1]# mknod /dev/tap0 c 90 128
[root@hhh tun-1.1]# modprobe tap0
FATAL: Module tap0 not found.

you don't need to do the 'mktun' per se.
Use

modeprobe tap

instead, but OpenVPN will do this for you as well

I am reinstall OpenVPN and enter

modeprobe tap

terminal answer

[root@hhh openvpn-2.1.4]# modeprobe tap
bash: modeprobe: command not found

whoops, my bad on the 'modeprobe', that should have been modprobe.
and on my fc13 box here I can also not do 'modprobe tap' .

Have you tried

openvpn --mktun --dev tap0

?

I don't see a /dev/net/tap0 either, but

/sbin/ifconfig tap0

shows the interface is there.
