[ilugd] Syncing Servers
Hi, I need your suggestions friends. My friend has two machines which he wants to use as test LAMP servers. He would also use the same machines as a mail servers. He wants to keep the two machine in sync so that if one of those fails (for any reason) the mails and LAMP business keep going on the other machine. How can we do this?

Assuming he's writing code, I'm guessing one's his development server and the other's his production server. If that is the case, do use a versioning system and work on two different branches. -- Artagnon (.com) ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/

HI again, Is it possible, that the two machine be exact replica of each other (which remain in sync), running in parallel so that we have a fail-over system? Umm.. I am having this strong feeling that its possible, but I don't know how is it done. Please give me some pointers.

The first thing you need for high availability is data sharing. If the applications permit it, you can have separate stores and application-level sync (e.g. replication in MySQL). If the application doesn't do sync by itself (e.g. mail), you need a highly available shared data store between the two servers. Ideally you would have some sort of NAS or SAN storage with multiple network paths, dual or triple power supplies and dual redundant RAID and disk controllers. Apart from the shared storage you need a heartbeat and address and process migration infrastructure. The Linux HA project provides these facilities IIRC.

Re: [ilugd] Syncing Servers
The first step would be to ensure that the data used by the lamp applications and mail servers is replicated on both the machines in near real time. this can be done thru DRBD and a network share like (NFS or iscsi) DRBD is kind of a RAID 1 over a network.If one of the drives or servers goes down then the other one assumes its identity and the application accesses the data over a network as if nothing happened. The next is to have a HA daemon such as Heartbeat that monitors the services that you want to have always running. This will monitor if the Primary server has failed and in such an event will make the secondary server the primary server (meaning that the secondary server will assume the identity of the promary and will continue to service client/service requests) Hope this helps Vikram Ranade ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
