Editing Zimbra on OpenVZ on Debian

These are instructions for getting [http://www.zimbra.com/ Zimbra]
to work under OpenVZ
using a Debian-3.1 (sarge) base.  They are inspired by 
[[Zimbra on OpenVZ on CentOS]]...

== Prepare the container == 

=== Template  ===

Create a Debian 3.1 (sarge) template ([[Debian template creation]])

=== Create ===

Create a container for Zimbra.   Make sure it has at least 6GB of free 
disk space available.

=== Limits ===

Adjust its resource limts:
 <code>
          vzctl set $CTID \
                --kmemsize      30000000:30000000 \
                --privvmpages   2400000:2400000 \
                --shmpages      256:256 \
                --numproc       2000:2000 \
                --numtcpsock    1000:1000 \
                --numflock      10000:10000 \
                --tcpsndbuf     640000:650000 \
                --tcprcvbuf     640000:650000 \
                --othersockbuf  640000:650000 \
                --numothersock  1000:1000 \
                --numfile       16384:16384 \
                --iptables      ipt_REJECT \
                --iptables      ipt_tos \
                --iptables      ipt_limit \
                --iptables      ipt_multiport \
                --iptables      iptable_filter \
                --iptables      iptable_mangle \
                --iptables      ipt_TCPMSS \
                --iptables      ipt_tcpmss \
                --iptables      ipt_ttl \
                --iptables      ipt_length \
                --save
 </code>

{{Inconsistent UBC warning}}

=== No Hostname ===

Use vzctl to give it an IP address but not a hostname:
  <code>vzctl set $CTID --ip A.B.C.D --save</code>

== Add/Remove packages ==

Enter the container and install/remove some packages:
 <code>
    dpkg --purge exim4
    apt-get install install sudo libidn11 curl fetchmail \
            libgmp3 libxml2 openssl libstdc++6 
    apt-get install perl perl-modules libexpat1 ssh file
</code>


For Debian 4 (etch) :
 <code>
    dpkg --purge exim4
    apt-get install install sudo libidn11 curl fetchmail \
            libgmp3c2 libxml2 openssl libstdc++6 libltdl3
    apt-get install perl perl-modules libexpat1 ssh file
</code>


== Install ==

Download the Zimbra installation tarball, unpack it, and run "install.sh".

== Verify ==

Check /proc/user_beancounters.   If there is anything but zero 
in the <code>failcnt</code> column, start over with higher limits.
