To install CATS you need to have git and sudo installed: # apt-get install git sudo User, under which you will deploy CATS should be in sudoers (sudo group). Clone this repo: $ git clone git://github.com/klenin/cats-main.git Look at deploy.bash, adjust, if needed, http_proxy (and set env_keep in /etc/sudoers, see comments in deploy.bash) and group, that your apache runs under. Then simply execute script: $ ./deploy.bash And if everything is ok you should copy Connect.pm.template to Connect.pm in cgi-bin/CATS/ and adjust connection settings to your DB. Congratulations, you now have a working CATS setup.
