New FreeRADIUS Deployment

[Julson, Jim]

#######
Q:  RADIUS Server:  any CPU, 4 GB RAM, any disk space / any Linux
A:  A reasonable amount of Disk space, something like 30GB should be more than sufficient, particularly if your SAN is housing your databases.  As for distro, I'm a fan of CentOS 6.2/6.3 or Ubuntu 12.04.  I actually have both in production behind load balancers.
#######

#######
Q:  Database Server:  any CPU, RAM (???), disk space (???), MySQL / any Linux
A:  This is just me, but I'd suggest running both MySQL and FreeRADIUS on the same servers if you can keep the actually data off of the server, and on a SAN.  This is because in terms of processor, RAM, and Network IO, MySQL won't peg the system very hard at all.  Of course, if budget is of no consequence, then of course separating out services is always fine.  But I like to keep all my DB queries local where I can, especially for network intensive operations.  This will have to be looked at and integrated into your environment based upon your current variables.  There are just too many ways to go, and there is no 1 particulary "right way". (Though some may disagree)

To touch on this further though, RAM is cheap, and if you house them on the same servers, I'd probably make sure you had 6GB to dedicate to MySQL, and about 2-4GB to the OS.  Getting 12GB of RAM on a system nowadays is nothing, so if you can, I'd do that.

#######
Q:  Additional:  SAN to enable database cluster (any tip?)
A:  If you have a SAN Available, it's pretty straight forward.  You will create a volume,  carve out a LUN, assign it to the Linux Servers, and then mount the partition to begin using it.  Both of your FreeRADIUS MySQL Servers servers will point to the same data, thereby giving you good speed, a single point of management, as well as great redundancy with the SAN.

Ok, friends,

Thank you very much for start discussing.  Let's get that more objective.

RADIUS Server:  any CPU, 4 GB RAM, any disk space / any Linux
Database Server:  any CPU, RAM (???), disk space (???), MySQL / any Linux
Additional:  SAN to enable database cluster (any tip?)

Am I right?  What would be answers to the question marks?

Kind regards,

My message was truncated somehow...

For point 1, I was going to just say, the more spindles for the hard drives the better, and a normal amount of RAM, like 4GB or so.  You will have a decent amount of IOPS, especially if you go with MySQL.  However, point 2 might take care of that.

1.       What would be recommended server hardware (memory, disk, CPU, ...) and software (Linux distribution, kernel version, ...)?

Anything standard and new will do the trick here.  You don't need "Pie in the sky", just make sure you have


2.       How could I synchronize both servers' users?  I mean, in the beginning, I'd have two separate /etc/shadow files but this is not scalable.  I need to share a single file between both servers.  Is it possible?  How?

Do you have a SAN that you could utilize?  For performance, I'd suggest a MySQL Cluster running on something with quite a few spindles.  The SAN provides great performance in that arena.  Otherwise, you are looking at having to do a Master/Slave scenario for MySQL DB Replication


3.       Any recommendations to the backup policy?

Just your standard nightly full backups to disk, then to either tape, SAN or offsite storage of some kind.
