I would like to run some basic services like www and mail on a test network. I would like to set up the servers so if one server falls over the other will take over the services automatically, load balanceing would be good as well. I have googled, I could be looking in the wrong place , there seems not to be much in regard to seting up freebsd in a cluster, lots on linux. I have looked at the High Availability Linux project , I see on the front page that it will run on freebsd. So I am a bit lost and i am wanting to learn how to cluster freebsd web and mail servers, I have looked at Beowulf clusters, which seem to give computers more grunt, Can some on on the list please advise me on what clustering softwhere i need to get started and if the High Availability Linux project softwhere will do the job. web links any thing to help me get started would be good. No I do not want to change over to linux.

Additionally doing some googling revealed "SG Cluster" (http://www.freebsd.org.hk/html/sgcluster/) though I'm not sure how active this is and/or really if it's what your looking for. ~Paul From owner-freebsd-cluster@FreeBSD.ORG Tue Aug 5 09:35:35 2008 Return-Path: Delivered-To: freebsd-cluster@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 44C53106567D; Tue, 5 Aug 2008 09:35:35 +0000 (UTC) (envelope-from rkramer@mweb.com) Received: from mwbmarshal.mweb.com (mwbmarshal.mweb.com [196.2.141.6]) by mx1.freebsd.org (Postfix) with ESMTP id B7C0E8FC13; Tue, 5 Aug 2008 09:35:33 +0000 (UTC) (envelope-from rkramer@mweb.com) Received: from mwbfes1.mweb.com (Not Verified[196.2.141.73]) by mwbmarshal.mweb.com with NetIQ MailMarshal 6.0 Service Pack 1 (v6, 0, 3, 28) id ; Tue, 05 Aug 2008 11:20:00 +0200 Received: from MWBEXCH.mweb.com ([196.2.141.75]) by mwbfes1.mweb.com with Microsoft SMTPSVC(6.0.3790.3959); Tue, 5 Aug 2008 11:20:00 +0200 X-MimeOLE: Produced By Microsoft Exchange V6.5 Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Date: Tue, 5 Aug 2008 11:19:59 +0200 Message-ID: <39DC135F7F0571489196E0B6F5D58B4A03B45FC9@MWBEXCH.mweb.com> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: High Availability FreeBSD www cluster Thread-Index: Acj20BV5r7qgMt71QwCmmmHI3+awtwAC9zfw References: <4898065A.5080008@powerzone.net.au> From: "Rudi Kramer - MWEB" To: "Michael Christie" , , X-OriginalArrivalTime: 05 Aug 2008 09:20:00.0454 (UTC) FILETIME=[6F88E660:01C8F6DC] Cc: Subject: RE: High Availability FreeBSD www cluster X-BeenThere: freebsd-cluster@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Clustering FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 05 Aug 2008 09:35:35 -0000 Michael Christie: > I want to cluster some freeBSD servers, The purpose of this is to > learn.

I also did some research a while ago and found Wackamole. It looks pretty interesting as you don't need a central "director" server but all servers in the cluster check each other.

Neither of the two applications the OP mentioned needs anything like as tight a coupling as what many com= mercial 'cluster' solutions provide, or that compute-cluster solutions like Beowulf or Grid Engine[!] provide. WWW clustering requires two things: * A means to detect failed / out of service machines and=20 redirect traffic to alternative servers * A means to delocalize user sessions between servers The first requirement can be handled with programs already mentioned such as wackamole/spread or hacluster -- or another alternative is=20 hoststated(8)[*] on OpenBSD. You can use mod_proxy_balancer[+] on recent= =20 Apache 2.2.x to good effect. Certain web technologies provide this sort of capability directly: eg. mod_jk or the newer mod_proxy_ajp13 modules for apache can balance traffic across a number of back-end tomcat= =20 workers: of course this only applies to sites written in Java. If you're dealing with high traffic levels and have plenty of money to=20 spend, then a hardware load balancer (Cisco Arrowpoint, Alteon Acedirecto= r,=20 Foundry ServerIron etc.) is a pretty standard choice. The second requirement is more subtle. Any reasonably complicated web application nowadays is unlikely to completely stateless. Either you have to recognise each session and direct the traffic back to the same server each time, or you have to store the session state in a way that is accessible to all servers -- typically in a back-end database.=20 Implementing 'sticky sessions' is generally slightly easier in terms of=20 application programming, but less resilient to machine failure. There are other alternatives: Java Servlet based applications running under Apache Tomcat can cluster about 4 machines together so that session state is replicated to all of them. This solution is however not at all scalable beyond 4 machines, as they'll quickly spend more time passin= g state information between themselves than they do actually serving incomi= ng=20 web queries. Mail clustering is an entirely different beast. In fact, it's two different beasts with entirely different characteristics. The easy part with mail is the MTA -- SMTP has built in intrinsic concept= s=20 of fail-over and retrying with alternate servers. Just set up appropriat= e=20 MX records in the DNS pointing at a selection of servers and it all shoul= d=20 work pretty much straight away. You may need to share certain data betwe= en=20 your SMTP servers (like greylisting status, Bayesian spam filtering,=20 authentication databases) but the software is generally written with this= =20 capability built in. The hard part with mail clustering is the mail store which provides the IMAP or POP3 or WebMail interface to allow users to actually read their=20 mail. To my knowledge there is no freely available opensource solution that provides an entirely resilient IMAP/POP3 solution. Cyrus Murder comes close, in that it provides multiple back-end mail stores, easy=20 migration of mailboxes between stores and resilient front ends. The=20 typical approach here is to use a high-spec server with RAIDed disk=20 systems, multiple PSUs etc. and to keep very good backups.

In every time only one machine works and provide some services (www, db, etc) Very good idea is to use NAS(SAN) - Network Access Storage ( http://en.wikipedia.org/wiki/Network-attached_storage ) with shared disk. Both nodes of HA cluster will use this shared disk (but only one in certain time). If one node fails, second node (standby node) will become a master of cluster and will start some services, that cluster provided. But NAS systems is not cheap!! Another way is to use software systems such us DRBD, NFS, chironfs, rsync etc. Most of this high-availability software solution works by replicating a disk partition in a master/slave mode. Heartbeat + DRBD is one of most popular redundant solutions. DRBD mirrors a partition between two machines allowing only one of them to mount it at a time. Heartbeat then monitors the machines, and if it detects that one of the machines has died, it takes control by mounting the mirrored disk and starting all the services the other machine is running. Unfortunately DRBD runs only on linux but I recommend you to see how it works for understanding this technology. http://www.rhic.bnl.gov/hepix/talks/041020am/miers.pdf http://www.linux-ha.org http://www.linux-ha.org/DRBD/GettingStarted http://www.linuxjournal.com/article/9074 For freebsd to mirror content on bouth nodes you can use rsync as in this howto: http://www.taygeta.com/ha-postgresql.html Another way like as DRBD is to use chironfs + nfs (sysutils/fusefs-chironfs/) http://www.furquim.org/chironfs Also look at CARP (Common Address Redundancy Protocol) man carp http://www.openbsd.org/faq/pf/carp.html http://www.postgresql.org/docs/8.3/static/high-availability.html (for databases) ps. sorry for my eng -- Best Wishes, PAIX-UANIC | SK3929-RIPE From owner-freebsd-cluster@FreeBSD.ORG Wed Aug 6 16:19:43 2008 Return-Path: Delivered-To: freebsd-cluster@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id C572E1065677 for ; Wed, 6 Aug 2008 16:19:43 +0000 (UTC) (envelope-from raggen@passagen.se) Received: from av10-2-sn2.hy.skanova.net (av10-2-sn2.hy.skanova.net [81.228.8.182]) by mx1.freebsd.org (Postfix) with ESMTP id 59D018FC1E for ; Wed, 6 Aug 2008 16:19:43 +0000 (UTC) (envelope-from raggen@passagen.se) Received: by av10-2-sn2.hy.skanova.net (Postfix, from userid 502) id A8F6E37F2C; Wed, 6 Aug 2008 17:54:05 +0200 (CEST) Received: from smtp4-1-sn2.hy.skanova.net (smtp4-1-sn2.hy.skanova.net [81.228.8.92]) by av10-2-sn2.hy.skanova.net (Postfix) with ESMTP id 6624F37F2C; Wed, 6 Aug 2008 17:54:05 +0200 (CEST) Received: from [192.168.1.31] (90-230-141-139-no41.tbcn.telia.com [90.230.141.139]) by smtp4-1-sn2.hy.skanova.net (Postfix) with ESMTP id 9D09A37E4C; Wed, 6 Aug 2008 17:54:02 +0200 (CEST) Message-ID: <4899C919.1060903@passagen.se> Date: Wed, 06 Aug 2008 17:54:01 +0200 From: Roger Olofsson User-Agent: Thunderbird 2.0.0.16 (Windows/20080708) MIME-Version: 1.0 To: Michael Christie References: <4898065A.5080008@powerzone.net.au> In-Reply-To: <4898065A.5080008@powerzone.net.au> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Cc: freebsd-questions@freebsd.org, freebsd-cluster@freebsd.org Subject: Re: High Availability FreeBSD www cluster X-BeenThere: freebsd-cluster@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Clustering FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 06 Aug 2008 16:19:43 -0000 Michael Christie skrev: > Hi all , > > I want to cluster some freeBSD servers, The purpose of this is to > learn.

My setup was a firewall/gateway consisting of more than 1 machine using freevrrpd thus enabling failover for the firewall/gateway. I write firewall and not firewalls since freevrrpd creates a virtual ip that is failover'ed between the machines. On the firewall/gateway pen were running and pointed towards the web servers. Pen can point at as many web servers as you like and balances the load between them in a very simple way. If the web servers are identical in setup they become redundant.

You can do round-robin RDR with PF to distribute the load. You can even put the same server IP more than one time in the list to forward more traffic to this server! I tested it but I didn't tried CARP yet. I read I couple of articles on CARP with BSD, I'm a little bit surprised that nobody made reference to it yet.

Is you have to LB/RP from a front end (the SPOF?) you can also take a quick look on LighttpD with the Proxy module (very simple & efficient) In a heavier (but also quite simple) environment : * Two (or more) LB/RP on the front with lighttpdproxy - HA with CARP * Two (or more) Load Balanced Web "Back End" servers ;) On jeu, 2008-08-07 at 16:44 +1000, Michael Christie wrote: > Thank you all for your input.
