Introduction

The Radicale Project is a complete calendar and contact storing and manipulating solution. It can store multiple calendars and multiple address books.

Calendar and contact manipulation is available from both local and distant accesses, possibly limited through authentication policies. This HOWTO describes the installation procedure for installing Radicale around the Roundcube installation on an SME installation. Before installation On sme8, you need to install python26 

yum --enablerepo=ces-standard,epel --nogpgcheck install python26

Not need in sme9, python-2.6 is installed. But you have to do: 

ln -s /usr/bin/python2.6 /usr/bin/python26

in order to use same init script as for sme8

Download & Install Radicale

mkdir -p /opt/roundcube/
cd /opt/roundcube/
wget –no-check-certificate http://pypi.python.org/packages/source/R/Radicale/Radicale-1.0.1.tar.gz
tar xvfz Radicale-1.0.1.tar.gz
rm -f Radicale-1.0.1.tar.gz
mv Radicale-1.0.1 radicale
mkdir -p /home/e-smith/files/.radicale/collections
mkdir -p /etc/radicale
mkdir -p /var/run/radicale

Next, you need to configure how you want the logs: 

touch /etc/radicale/logging
cat <<EOF > /etc/radicale/logging
[loggers]
keys=root
level=NOTSET

[logger_root]
handlers=file

[formatters]
keys=simple

[formatter_simple]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s

[handlers]
keys=file

[handler_file]
class=handlers.TimedRotatingFileHandler
interval=midnight
backupCount=5
formatter=simple
level=ERROR
args=('/var/log/radicale.log',)
EOF

Set Radicale to start on system startup To make Radicale start automagically, create 

vim /etc/rc.d/init.d/radicaled

with the following content:
