These manual guides also include how to set up the Hotspot as a RADIUS client:

You didnt understand me I want to I have one radius server on mikrotik so that other network access points associated with a hotspot on the radius server on Main Access Point, it would be easier to add users only to the RADIUS server rather than on each access point 
You didn’t specify that
You also didn’t read the links I posted: http://wiki.mikrotik.com/wiki/User_Manager/Hotspot_Example describes how to set up User Manager, which is the only option for running a RADIUS server on RouterOS.
yes but I need radius SERVER on mikrotik
User Manager IS a RADIUS server. It is also the ONLY RADIUS server that you can run on RouterOS, unless you install a virtual machine via MetaROUTER and KVM.
I do all the steps as written but on the end when I try to login write me: RADIUS SERVER IS NOT Responding
So post the configuration you applied - people can’t guess at what you did.
I do all next steps:
/ ip hotspot profile set hsprof1 use-radius=yes
/ radius add service=hotspot address=127.0.0.1 secret=123456
/ tool user-manager customer add login="MikroTik" password="qwerty" permissions=owner
/ tool user-manager router add subscriber=MikroTik ip-address=127.0.0.1 shared-secret=123456
theat is steps from http://wiki.mikrotik.com/wiki/User_Manager/Hotspot_Example
and when I try to login on my hotspot write a RADIUS SERVER IS NOT Responding pls help
Do you have a radius server running on localhost? Or is it remote?
On Mikrotik
That is unhelpful. Of course it’s installed on a Mikrotik router, it cannot install on anything else.
Did you install User Manager on the same AP you are getting the “RADIUS server is not responding” error message on (localhost), or is the RADIUS server on a different router than the one showing the error message you are getting (external)?
On same router
and I try to add new users but notthing
