These are instructions for getting Zimbra to work under OpenVZ using a Debian-3.1 (sarge) base. They are inspired by Zimbra on OpenVZ on CentOS...
For Debian 4 installation there are little changes see here OpenVZ on Debian 4 (etch)
Contents
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:
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

Warning: The above UBC values might not be consistent; see UBC consistency check. |
No Hostname
Use vzctl to give it an IP address but not a hostname:
vzctl set $CTID --ip A.B.C.D --save
Add/Remove packages
Enter the container and install/remove some packages:
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
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 failcnt column, start over with higher limits.
