====== Install on Lenny, Dovecot, MyDns and ISPConfig3 ======

I've started this installation using a precreated template of Debian 5 (Lenny) minimal, downloaded from:\\
[[http://download.openvz.org/template/precreated/contrib/debian-5.0-i386-minimal.tar.gz|download.openvz.org]]

I've also done a mix of the next howtos from the guru at [[http://www.howtoforge.com/|www.howtoforge.org]]

  * [[http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3-p3|perfect-server-debian-lenny]]
  * [[http://www.howtoforge.com/installing-a-multiserver-setup-with-dedicated-web-email-dns-and-mysql-database-servers-on-debian-5.0-with-ispconfig-3|installing-a-multiserver-setup]]

===== 1 - Setup the Virtual Environment =====

Create a container based on the just downloaded template, specify an IP address, an hostname, a nameserver.
I also give to the root user, a password

  vzctl create 1100 --ostemplate debian-5.0-i386-minimal --config vps.custom
  vzctl set 1100 --ipadd 192.168.0.100 --save
  vzctl set 1100 --hostname ic3.dw.lan --save
  vzctl set 1100 --nameserver 192.168.0.22 --save
  vzctl set 1100 --userpasswd root:your-root-password


This is the configuration file i've used

  nano /etc/vz/conf/1100.conf

<file bash 1100.conf>
# Primary parameters

# to be approximately equivalent to 50000 CPU units)
CPUUNITS="50000"
CPUS="1"
ONBOOT="yes"

#
VE_ROOT="/var/lib/vz/root/$VEID"

CAPABILITY="CHOWN:on DAC_READ_SEARCH:on SETGID:on SETUID:on NET_BIND_SERVICE:on NET_ADMIN:on SYS_CHROOT:on SYS_NICE:on "
 
</file>

This last line is important especially for the FTP server that we install later, if not present PureFTPd wont start


===== 2 - Updating the Virtual Environment =====

Start the container and enter as root

  vzctl start 1100
  vzctl enter 1100


Set the correct timezone, choosing the right value (mine is Europe/Rome):

  dpkg-reconfigure tzdata


Make sure that your **/etc/apt/sources.list** contains the right links to the debian repositories, like this

  nano /etc/apt/sources.list

<file bash sources.list>
## Debian Stable (Lenny)
deb http://ftp.it.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp.it.debian.org/debian/ lenny main contrib non-free
 
## security updates
deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free
 
## this is to always get the newest updates for the ClamAV virus scanner, this
## project publishes releases very often, and sometimes old versions stop working
deb http://volatile.debian.org/debian-volatile lenny/volatile main contrib non-free
 
</file>


Update the apt package database and and install updates
<code bash>
apt-get update
</code>

One time i have got an error, related to gpg keys, after adjusting the **/etc/apt/sources.list**, so before proceed, i've done this
<code bash>
apt-get install debian-archive-keyring
</code>

Then again, and the problem vanished
<code bash>
apt-get update
</code>

Finally, install updates
<code bash>
apt-get -y upgrade
</code>



===== 3 - Installing Mail & Database packages =====

Install Postfix, Dovecot and MySQL with one single command
<WRAP prewrap>
<code bash>
apt-get -y install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d
</code>
</WRAP>

Enter the new password for MySQL when requested by the installer, and answer the next questions like these
  * Create directories for web-based administration ? <- **No**
  * General type of configuration? <- **Internet site**
  * Mail name? <- **ic3.dw.lan**
  * <del>SSL certificate required <- **Ok**</del>

If you want MySQL to listen on all interfaces, and not just localhost, edit **/etc/mysql/my.cnf** and add a comment in front of the line that begin with **bind-address**, like this
<file bash>
[...]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address = 127.0.0.1:
[...]
</file>

Then restart MySQL
<code bash>
/etc/init.d/mysql restart
</code>

To check that networking is enabled. Run
<code bash>
netstat -tap | grep mysql
</code>

The output should look like this
<code bash>
root@ic3:/# netstat -tap | grep mysql
tcp        0      0 *:mysql                 *:*                     LISTEN      6612/mysqld
root@ic3:/#
</code>


As I am not interested in make an antivirus/antispamming server, then I totally skip the entire chapter



===== 4 - Installing Webserver with PHP5 package =====

Now install Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear, and mcrypt as follows
<WRAP prewrap>
<code bash>
apt-get -y install apache2 apache2.2-common apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert libapache2-mod-php5 php5 php5-common php5-gd php5-mysql php5-imap phpmyadmin php5-cli php5-cgi libapache2-mod-fcgid apache2-suexec php-pear php-auth php5-mcrypt mcrypt php5-imagick imagemagick libapache2-mod-suphp libopenssl-ruby libapache2-mod-ruby sudo
</code>
</WRAP>

You need to answer the following question

  * Web server to reconfigure automatically: <- **apache2**

Then run the following command to enable some Apache modules
<code bash>
a2enmod suexec rewrite ssl actions include ruby dav_fs dav auth_digest
</code>

Restart Apache to activate new configuration
<code bash>
/etc/init.d/apache2 restart
</code>



===== 5 - Installing vlogger, webalizer, and awstats packages =====

Install vlogger, webalizer, and awstats:
<code bash>
apt-get -y install vlogger webalizer awstats
</code>

Then open **/etc/webalizer/webalizer.conf** and change the line starting with **Incremental**, like this
<file bash>
[...]
Incremental yes
[...]
</file>



===== 6 - Installing FTP package =====

PureFTPd can be installed with the following command
<code bash>
apt-get -y install pure-ftpd-common pure-ftpd-mysql
</code>

Edit the file **/etc/default/pure-ftpd-common**
<code bash>
nano /etc/default/pure-ftpd-common
</code>

and change the start mode from **inetd** to **standalone** and set **VIRTUALCHROOT=true**, like this
<file bash>
[...]
STANDALONE_OR_INETD=standalone
[...]
VIRTUALCHROOT=true
[...]
</file>

Edit the file **/etc/inetd.conf** to prevent inetd from trying to start ftp. Add a comment in front of the line that begin with **ftp**, like this
<file bash>
[...]
#ftp    stream  tcp     nowait  root    /usr/sbin/tcpd /usr/sbin/pure-ftpd-wrapper
[...]
</file>

Some additional settings for pureftpd
<code bash>
echo 'yes' > /etc/pure-ftpd/conf/DontResolve
</code>

Enable TLS in pureftpd
<code bash>
echo 1 > /etc/pure-ftpd/conf/TLS
mkdir -p /etc/ssl/private/
openssl req -x509 -nodes -newkey rsa:1024 -keyout /etc/ssl/private/pure-ftpd.pem  -out /etc/ssl/private/pure-ftpd.pem
</code>

You need to answer the following questions

  * Country Name (2 letter code) [AU]: <- **IT**
  * State or Province Name (full name) [Some-State]: <- **Bagnolo in Piano**
  * Locality Name (eg, city) []: <- **Reggio Emilia**
  * Organization Name (eg, company) [Internet Widgits Pty Ltd]: <- **italmedia.net**
  * Organizational Unit Name (eg, section) []: <- **Internet Server**
  * Common Name (eg, YOUR name) []: <- **ic3.dw.lan**
  * Email Address []: <- **k-root@rete.us**

<code bash>
chmod 600 /etc/ssl/private/pure-ftpd.pem
</code>

Then start PureFTPd:
<code bash>
/etc/init.d/pure-ftpd-mysql start
</code>



===== 7 - Install MyDNS package =====

Before install MyDNS, we need to install a few prerequisites
<code bash>
apt-get -y install g++ libc6 gcc gawk make texinfo libmysqlclient15-dev
</code>

MyDNS is not available in the Debian Lenny repositories, therefore we have to build it ourselves as follows
<code bash>
cd /tmp
wget http://heanet.dl.sourceforge.net/sourceforge/mydns-ng/mydns-1.2.8.27.tar.gz
tar xvfz mydns-1.2.8.27.tar.gz
cd mydns-1.2.8
./configure
make
make install
</code>

Next we create the start/stop script for MyDNS
<code bash>
nano /etc/init.d/mydns
</code>

<file bash mydns>
#! /bin/sh
#
# mydns         Start the MyDNS server
#
# Author:       Philipp Kern <phil@philkern.de>.
#               Based upon skeleton 1.9.4 by Miquel van Smoorenburg
#               <miquels@cistron.nl> and Ian Murdock <imurdock@gnu.ai.mit.edu>.
#
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/sbin/mydns
NAME=mydns
DESC="DNS server"
SCRIPTNAME=/etc/init.d/$NAME
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
case "$1" in
  start)
        echo -n "Starting $DESC: $NAME"
        start-stop-daemon --start --quiet \
                --exec $DAEMON -- -b
        echo "."
        ;;
  stop)
        echo -n "Stopping $DESC: $NAME"
        start-stop-daemon --stop --oknodo --quiet \
                --exec $DAEMON
        echo "."
        ;;
  reload|force-reload)
        echo -n "Reloading $DESC configuration..."
        start-stop-daemon --stop --signal HUP --quiet \
                --exec $DAEMON
        echo "done."
        ;;
  restart)
        echo -n "Restarting $DESC: $NAME"
        start-stop-daemon --stop --quiet --oknodo \
                --exec $DAEMON
        sleep 1
        start-stop-daemon --start --quiet \
                --exec $DAEMON -- -b
        echo "."
        ;;
  *)
        echo "Usage: $SCRIPTNAME {start|stop|restart|reload|force-reload}" >&2
        exit 1
        ;;
esac
exit 0
</file>

Then we make the script executable and create the system startup links for it
<code bash>
chmod +x /etc/init.d/mydns
update-rc.d mydns defaults
</code>



===== 8 - Install Jailkit package =====

Jailkit is needed only if you want to chroot SSH users \\
<wrap em>
important: Jailkit must be installed before ISPConfig - it cannot be installed afterwards!
</wrap>

It can be installed as follows but, some prerequisites first
<code bash>
#apt-get -y install build-essential autoconf automake1.9 libtool flex bison
cd /tmp
#wget http://olivier.sessink.nl/jailkit/jailkit-2.11.tar.gz
wget http://cosmos.rete.us/sw/jailkit-2.11.tar.gz
tar xvfz jailkit-2.11.tar.gz
cd jailkit-2.11
./configure
make
make install
cd ..
rm -rf jailkit-2.11*
</code>



===== 9 - Install fail2ban package =====

This is optional but recommended, because the ISPConfig monitor tries to show the log
<code bash>
apt-get -y install fail2ban
</code>



===== 10 - Install ISPConfig 3 package =====

To get the latest ISPConfig 3 stable release, please visit the [[http://www.ispconfig.org/ispconfig-3/download/|ISPConfig website]]

Or install ISPConfig 3 from the latest released version, like this
<code bash>
cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install/
</code>

Then start the install script
<code bash>
php -q install.php
</code>
