SMEServer v8.0 in OpenVZ

SMEServer v8.0 in OpenVZ

This is a work in progress and does not yet work.

Initial CentOS Virtual Machine

• Start with a CentOS 5 Minimal Template in Proxmox VE OpenVZ Container
• Rename template to conform to ProxmoxVE naming convention and move to template cache

cd /var/lib/vz/template/cache
wget http://download.openvz.org/contrib/template/precreated/centos-5-i386-minimal.tar.gz
mv centos-5-i386-minimal.tar.gz centos-5-minimal_5_i386.tar.gz

• 512 MB RAM / 8 GB HDD / IP address assigned during VM creation / SELinux disabled / sshd enabled
• Start Container
• 88 RPMs pre-installed list

rpm -qa --qf "%{n}-%{v}-%{r}.%{arch}.rpm\n" > /tmp/centOS5_minimal_after_yum_with_arch.txt

• 590 RPMs in SME8 installed list - on Atom Hardware with 2GB RAM / 320 GB HDD
• Check the current CentOS Version with cat /etc/redhat-release to be CentOS release 5 (Final)

• Check the installed groups with yum grouplist:

Installed Groups:
   System Tools
   Yum Utilities
Available Groups:
   Administration
....

The RPMs that now stand installed are listed here..

Install screen

To enable background updates, screen is installed.

yum install screen

It is invoked / re-attached with screen -aR scrname and detached from the session with Ctrl-A d.

Take a backup of the Virtual Machine now before the mess that begins next.

Install the SME 8 RPMs

• Remove all current repos in /etc/yum.repos.d

mkdir /tmp/repo.bak
mv /etc/yum.repos.d/*.repo /tmp/repo.bak/

• Upload /etc/yum.repos.d/sme_base.repo
• UM install sme rpms

yum install smeserver\* e-smith\* --enablerepo=smeos8,smeupdates8 --nogpgcheck

• 287 MB / 374 RPMs Installed
• SMEServer uses runlevels 7 and 4

rm -f /etc/rc4.d/*
cp -a /etc/rc7.d/* /etc/rc4.d/

• Now get the list of installed RPMs

ABC=`rpm -qa`
echo ${ABC} > sme8_rpms_after_yum.txt
ABC=

• Some RPMs get removed and others get updated.
• Use a MySQL database to check the differences:

CREATE DATABASE `rpmmatch`CHARACTER SET latin1 COLLATE latin1_general_ci; 
CREATE TABLE `rpmmatch`.`smerpms`( `rpmname` VARCHAR(100) NOT NULL, PRIMARY KEY (`rpmname`) ); 
CREATE TABLE `rpmmatch`.`c5minrpms`( `rpmname` VARCHAR(100) NOT NULL, PRIMARY KEY (`rpmname`) ); 
LOAD DATA LOW_PRIORITY LOCAL INFILE 'C:\\smerpms.csv' INTO TABLE `rpmmatch`.`smerpms` FIELDS ESCAPED BY '\\' TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (`rpmname`); 
LOAD DATA LOW_PRIORITY LOCAL INFILE 'C:\\c5minrpms.csv' INTO TABLE `rpmmatch`.`c5minrpms` FIELDS ESCAPED BY '\\' TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (`rpmname`); 
SELECT a.* FROM c5minrpms a LEFT JOIN smerpms b USING (rpmname) WHERE b.rpmname IS NULL ORDER BY rpmname; 
SELECT a.* FROM smerpms a LEFT JOIN c5minrpms b USING (rpmname) WHERE b.rpmname IS NULL ORDER BY rpmname;

• 75 packages difference including 2 kernels not needed

Install Missing Packages

Since networking and sshd will not be working, ssh into the ProxmoxVE host and use vzctl enter <VEID> to work further. Edit the file /etc/sysconfig/network-scripts/ifcfg-venet0:

DEVICE=venet0
BOOTPROTO=static
ONBOOT=yes
IPADDR=127.0.0.1
NETMASK=255.255.255.255
BROADCAST=0.0.0.0
IPV6INIT="yes"

to be something like:

DEVICE=venet0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.60.110
NETMASK=255.255.255.0
GATEWAY=192.168.60.1
NETWORK=192.168.60.0
BROADCAST=192.168.60.255
IPV6INIT="yes"

Restart Networking with:

ifdown venet0 && ifup venet0

Now install the missing packages:

yum install mlocate xz xz-utils \
    zip unzip which vixie-cron vim-enhanced vim-common usbutils traceroute tnef time telnet tcpdump \
    syslinux sysfsutils strace setserial safecat rsync rp-pppoe rpm-build qmail-qfilter \
    pyxf86config perl-suidperl kudzu libgomp lockdev lsof maildrop man minicom mkbootdisk mod_ssl \
    mt-st mutt newt anacron at authconfig bc bind-libs bind-utils cdrecord cyrus-sasl \
    cyrus-sasl-md5 dhclient dhcp diald diald-top distcache dosfstools eject fetchmail ftp \
    gettext glib groff hdparm hesiod iptraf iptstate isdn4k-utils --nogpgcheck

• maildrop complained of key requirement and hence the --nogpgcheck
• pcmciautils is dependent on the kernel and hence avoided
