Mirroring Cpanel Servers

[mohdyasar]

Hello Members

I have been a consisten use of Cpanel for past 8 years, and provide shared hosting, however, there is one question, which is asked and will be asked by many of loyal cpanel hosters.

Can we mirror a cpanel server to an alternate location, and rsync data, on an ongoing basis, to keep data synced, so in the event of h/w/ sw/w dc failure we can still serve our customers, well.

Idea is we want a redundant setup, so we can switch if we have a major failure, at one of the DCs and switch back to primary DC when its back online.

Any ideas, on this, i have read many posts, but all seem to be confusing. Need to build a redundant setup of Cpanel Shared Hosting.

Regards

Hello,

There are various methods for syncing data. Clustering, DRBD etc. I will suggest you to gor DRBD which is very easy and simple.

Keep these URL's for your reference which had helped me a lot in DRBD setup.

Many thanks

One quick question is will it copy all accounts, mail accounts, as and when created on the primary node.

What happens if i have a clustered DNS and how do i take care of DNS in terms of Auto Failover, any thoughts
