Zimbra Debian Support

[tommie]

Hi,

I like zimbra a lot but we are using a shared server with umls. And zimbra uses a lot of resources. The uml got a load of 3.0 when sending a mail. This also impacts the host because the uml needs a lot of resources, so my collegues don't like running zimbra on the server .

Are there some tuning tips so I can reduce the load...?

Thanks!

Why does zimbra need its own mysql server

This is why we don't recommend installing in virtual machines.

Well, regarding the virtual machines statement, I have a small note on that

We are running a hosting environment with ESX 2.5 servers, running multiple instances of debian sarge and some different windows servers.

I have just installed a Debian Sarge, and done the modifications the other users have put into a list, and it just runs perfectly

It actually runs faster than on a FC 4.0 installation, i made last week, but that was also a M3 deployment.

Just my 2 cents !

Hi,

Me back again... I am now running Zimbra for a few days. It is realy stable and perfomance isn't an issue anymore. With baking the kernel an error was integrated into the config file. The highmem switch was turned off thats why zimbra was not working very well because not enough memory was available for all our virtual instances.

So thank you Marcmac for all your help and keep up the good work :-)

Regards,

so here's how my debian install went-
Just to preface, i've only used redhat-ES and gentoo in the past. This is my first debian install! After using gentoo for almost 2 years now, I'm almost more impressed with the fact that i don't have to wait for shit to compile then i am with zimbra



I started off with a minimal network install of debian 3.1-
upgraded everything that was out of date, and then switched to the debian 2.6.8 kernel.

ran the zimbra install script from the M4_62 debian tar

had to install several packages based on the script's pre-flight checks. re-ran the install.sh script. Install finished, but then then failed during "starting LDAP"
I read the logs and checked this forum and saw that i needed to apt-get openssl. Ok, done. Reinstall, everything installs ok this time.

So now i try to login and aren't able to get on... I try a reboot-
The zimbra service MTA fails because it can't find libxml2. So i apt-get libxml2, restart the services and then get an error about libldap and libphp5 missing.. shit..

So i reinstall zimbra again, now the install script complains that my hosts file is malformed.

I had an entry like this:
192.168.1.49 zimbra zimbra.mydomain.com
so i changed it to
192.168.1.49 zimbra.mydomain.com zimbra

and re-ran the install... (it's funny that the install script didn't care about the hosts file during the first 2 installs i did) After the 2nd reinstall i was able to login!

[edit]
somewhere in there i also killed whatever MTA debian pre-installed

So things aren't as smooth as i thought. I rebooted the machine and i'm getting the following error message. I'm going to try some ld action, i'll let you know what i can figure out.

[marcmac]

Check the forums for the /etc/ld.so.conf issue on debian, which is what's causing _most_ of your problems.

The libstdc++ issue is a missing compat library, - search the forums for that and you should find the package name.

Marcmac,

is there a way to upgrade to the released 3.0 version? Or can I copy my data?

Regards

As a note, the installer needs the package "perl-modules", which is not installed by default on debian sarge.

The installer will handle the upgrade for you. Just run install.sh and say yes to the upgrade question.
