Installation
Kallithea is written entirely in Python. Before posting any issues make sure, your not missing any system libraries and using right version of libraries required by Kallithea. There's also restriction in terms of mercurial clients. Minimal version of hg client known working fine with Kallithea is 1.6. If you're using older client, please upgrade.
Installing Kallithea from PyPI (aka "Cheeseshop")
Kallithea requires python version 2.6 or higher.
The easiest way to install kallithea is to run:
easy_install kallithea
Or:
pip install kallithea
If you prefer to install Kallithea manually simply grab latest release from http://pypi.python.org/pypi/Kallithea, decompress the archive and run:
python setup.py install

For installing Kallithea i highly recommend using separate virtualenv. This way many required by Kallithea libraries will remain sandboxed from your main python and making things less problematic when doing system python updates.

Assuming you have installed virtualenv create a new virtual environment using virtualenv command:
virtualenv --no-site-packages /opt/kallithea-venv
Note
Using --no-site-packages when generating your virtualenv is very important. This flag provides the necessary isolation for running the set of packages required by Kallithea. If you do not specify --no-site-packages, it's possible that Kallithea will not install properly into the virtualenv, or, even if it does, may not run properly, depending on the packages you've already got installed into your Python's "main" site-packages dir.
this will install new virtualenv into /opt/kallithea-venv.
Activate the virtualenv by running:
source /opt/kallithea-venv/bin/activate
Note
If you're using UNIX, do not use sudo to run the virtualenv script. It's perfectly acceptable (and desirable) to create a virtualenv as a normal user.
Make a folder for Kallithea data files, and configuration somewhere on the filesystem. For example:
mkdir /opt/kallithea
Go into the created directory run this command to install kallithea:
easy_install kallithea
or:
pip install kallithea
This will install Kallithea together with pylons and all other required python libraries into activated virtualenv
Requirements for Celery (optional)
In order to gain maximum performance there are some third-party you must install. When Kallithea is used together with celery you have to install some kind of message broker, recommended one is rabbitmq to make the async tasks work.
Of course Kallithea works in sync mode also and then you do not have to install any third party applications. However, using Celery will give you a large speed improvement when using many big repositories. If you plan to use Kallithea for say 7 to 10 repositories, Kallithea will perform perfectly well without celery running.
If you make the decision to run Kallithea with celery make sure you run celeryd using paster and message broker together with the application.
Note
Installing message broker and using celery is optional, Kallithea will work perfectly fine without them.
