Now that I've opened this multi-radius server can of worms ... is switching over to use the mysql backend on another host as simple as: 1) Installing mysql on another server; 2) Running the mysql.sql on that server to setup the radius database; 3) Changing the radiusd.conf (after backing it up) and un-commenting the area that deals with the mysql Thanks, Scott -----Original Message----- From: freeradius-users-bounces+scott=renshawauto.com@lists.freeradius.org [mailto:freeradius-users-bounces+scott=renshawauto.com@lists.freeradius.org] On Behalf Of Stefan Winter Sent: Tuesday, August 08, 2006 12:21 PM To: FreeRadius users mailing list Subject: Answer
Does Freeradius have the ability to use multiple nodes in similar fashion to name servers? An example of this would be a situation when the master freeradius server is down for some reason, but the slave freeradius server(s) continue to grant & deny access but do not receive any updates until the master is back up.
You can simply set up more than one FreeRADIUS instance. Then you have to tell your clients that more than one authentication server exists - pretty much the same as with DNS. But as with DNS, you should pay attention on how your clients will recover in case of a failure. Some may for example eternally use the "slave" even when the "master" is back up again. The reasons I use quotes is that there is no concept of superiority of one server vs. the other - they are just two equal alternatives to the client. For the "won't receive any updates" I'm not sure what you mean.
Also, if there are any HOWTO or example configurations of this type of setup, those would be very helpful.
Just setup the server twice (ideally both using _one_ authentication backend, e.g. a mySQL db on a different host that both can access) and tell your client devices about it.
