The following commands will add the Cherokee Web Server PPA to Ubuntu (version 9.10 and higher). The first command adds the extremely handy add-apt-repository program to your system. The second adds the Cherokee Personal Package Archive.

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:cherokee-webserver/ppa

At the moment, Cherokee is at version 1.0.9.

If you don’t already have Cherokee installed and you want to install it I find the following combination of packages most useful:

sudo apt-get update
sudo apt-get install cherokee cherokee-doc libcherokee-mod-libssl libcherokee-mod-streaming libcherokee-mod-rrd libcherokee-mod-admin spawn-fcgi
