ezjails, jails

[Don Munyak]

re: ezjails, jails

Hopefully a quick question. I am researching using EZJails from
http://erdgeist.org/arts/software/ezjail/

But a little confused by the jail concept.

I think I need to setup two jails, one(1) for email services and
one(1) for www services, on a single server.

q. If I am running a webserver for more than one(1) domain, should I
be using a single jail for each domain, or is one jail needed for
'ALL' www processing ?

q. If I am using a jail for each domain, does this imply loading
apache+php+mysql, for each www jail ?

q. Likewise with email and multiple domains, does multiple domains =
multiple email jails, as well as multiple copies of smtp, pop3,
webmail ??

q. Email and WWW services both require MySQL. Would I be installing
MySQL 'x' number of times?

What I want to do is he following:

We are a small company, so email traffic is minial..ie. less than 500
messages per day.
Likewise, www traffic is also minimal.
I want to build a single server to be located at a co-location facility.
This server would support both email and www services.

The email services would be built using instructions from
http://www.tnpi.biz/internet/mail/toaster.shtml
...that being stuff like qmail, RBL, spamassassin, clamav...etc
We have 5 separate domains for email services
The www services would be functionally similiar to LAMP
We have 5 separate domains for www

I would greatly appreciate any links or advice towards achiving my goals.

Thanks
