Can I use existing MySQL install?

[utdrmac]

Hello,
Is it possible to use an existing mysql installation instead of the built-in one? We already have MySQL 5.1.22 installed on our server and don't want another copy of the same thing running in parallel.

If this is possible, how do I configure zimbra to use ours?

Thanks,
Matthew

P.s. Same thing with apache. Can I use our apache install that is already servicing 15 domains?

Welcome to the forums,

It would be far better for you to run Zimbra on a separate virtual machine or box.

Zimbra uses it's own customized instances of a serious collection of software packages - OpenLDAP, MySQL, Apache, Tomca (4.5 prior) Jetty(5.0), Postfix, Lucene, Verity, ClamAV, SpamAssassin, DSPAM (though off by default) AMaViS/Amavisd-new, Aspell, James/Sieve, Perdition (4.5 prior), NGINX(5.0), etc.

VMware & VirtualBox are a common one's - Xen has some quirks but speed wise it's rather good - I've found Qemu & Parallels to be a little slower.

But if you want the fun...

There's a thread on MySQL around here somewhere...but it ain't a pretty process.
