Horde Groupware requires some prerequisite software before you can use it. In addition, there are other software packages which, while
not required, are recommended as without them you will experience very limited functionality. The following helps you to
install the required and recommended software packages on a Debian Etch (4.0) System.
*There is also a Horde 'Groupware Webmail Edition' this will not be the part of this how to*
*This how to will not cover your mailserver setup.*
*Note: this how to is just a draft and not really perfect - feel free to edit it and make it better*
I started with a new and fresh Debian(openvz-image)
You should update your system.
apt-get update && apt-get dist-upgrade
Install Apache and php and modules
apt-get install libapache2-mod-php5 apache2 apache2-mpm-prefork
You need the cli for the horde setup script!
apt-get install php5-cli
These php modules are needed for horde Groupware
apt-get install php-pear php5-gd php5-ldap php5-mcrypt php5-memcache
For webmail you need the imap extension
apt-get install php5-imap
If you want to use mysql as Database backend, you should install the php5-mysql extension
apt-get install php5-mysql
If you want to you postgresql as Database backend install php5-pgsql
apt-get install php5-pgsql
apt-get install mysql-server
You will be asked for a mysqlroot password - don't forget it ;)
After that you need to create a user and create grants.
mysql -p -e 'CREATE USER HORDE ...'
mysql -p -e 'grant all on horde.* to horde@localhost identified by "horde";'
Install Horde Groupware
Download and unpack it
tar -xvf horde-webmail-1.0.1.tar.gz
copy to /var/www and change owner
cp -r /root/horde-webmail-1.0.1 /var/www/horde
chown -r www-data:www-data horde
with php5-cli start the setup script
php5 -q /var/www/horde/scripts/setup.php
