There is no must have for a system using ispCP ω. This is only a recommendation:

Pentium III or K6-4 with 500 MHz
512 MB RAM
100 MB disk space (only for install of ispCP ω)
Debian (or even any other *NIX-Distribution)

All required packages are listed in ./docs/fedora-packages

Make sure you are logged in as root and MySQL is running.

# cd /root
# tar xjvf ispcp-omega-1.0.6.tar.bz2

# cd ./ispcp-omega-1.0.6

# wget http://download.fedora.redhat.com/pub/epel/5/ARCH/epel-release-5-3.noarch.rpm
# rpm -Uvh epel-release-5-3.noarch.rpm
# yum install `cat ./docs/Fedora/fedora-packages`

# cpan2rpm -i http://search.cpan.org/CPAN/authors/id/P/PH/PHOENIX/Term-ReadPassword-0.07.tar.gz
# wget -P /tmp/core http://hany.sk/mirror/fedora/releases/7/Everything/i386/os/Fedora/perl-Net-LibIDN-0.09-3.fc7.i386.rpm
# rpm -i /tmp/core/perl-Net-LibIDN-0.09-3.fc7.i386.rpm

Check the ispcp.conf and adapt it to your requirements.

# cp -f ./courier*.rpm /usr/local/
# cd /usr/local/

# wget http://www.thatfleminggent.com/packages/fedora/7/i386/courier-authlib-0.59.3-1.fc7.mf.i386.rpm
# wget http://www.thatfleminggent.com/packages/fedora/7/i386/courier-authlib-userdb-0.59.3-1.fc7.mf.i386.rpm
# wget http://www.thatfleminggent.com/packages/fedora/7/i386/courier-imap-4.1.3-1.fc7.mf.i386.rpm

# rpm -i courier-authlib-0.59.3-1.fc7.mf.i386.rpm
# rpm -i courier-authlib-userdb-0.59.3-1.fc7.mf.i386.rpm
# rpm -i courier-imap-4.1.3-1.fc7.mf.i386.rpm

Create group and user with 3000 UID so ispCP doesn't cause conflicts with user

# groupadd courier -g 3000
# useradd -u 3000 -c 'Courier Mail Server' -d /dev/null -g courier -s /bin/false courier

# make -f Makefile.fedora install

# cp -RLf /tmp/ispcp/* /
# cp -Rv /tmp/ispcp/etc/init.d /etc/rc.d/
# ln -s /etc/rc.d/init.d /etc/init.d

# mkdir /var/mail/virtual

# mv /var/named/data /var/named/data2
# ln -s /var/named/chroot/var/named/data /var/named/data

# mkdir /var/www/scoreboards

create sasl2 database:

# touch /etc/sasldb2

# echo 'include vhosts/*.conf' >> /etc/httpd/conf/httpd.conf

# mkdir -p /var/spool/postfix/etc
# cp /etc/sasldb2 /var/spool/postfix/etc/sasldb2

# chown apache:apache /var/www/ispcp/gui/tools/webmail/data

# cd /var/www/ispcp/engine/setup

# mysqladmin -u root password YOUR_PASSWORD

# perl ispcp-setup

(Be careful: the file /etc/named.conf must exist before you run the script. Otherwise setup will failed on trying to backup it! You can use the caching-nameserver package or the system-config-bind tool for create it or you can use touch!)

If you get no error, all went good; if you get one, look at http://isp-control.net to solve the problem.

# chmod 777 /var/www/ispcp/gui/phptmp

Install Daemon:

# chmod +x /etc/init.d/ispcp
# chkconfig --add ispcp
# service ispcp start

# rm -R /tmp/ispcp
