Installation on Unix/Linux
The following describes three different ways of installing Kallithea:
- :ref:`installation-source`: The simplest way to keep the installation up-to-date and track any local customizations is to run directly from source in a Kallithea repository clone, preferably inside a virtualenv virtual Python environment.
- :ref:`installation-virtualenv`: If you prefer to only use released versions of Kallithea, the recommended method is to install Kallithea in a virtual Python environment using virtualenv. The advantages of this method over direct installation is that Kallithea and its dependencies are completely contained inside the virtualenv (which also means you can have multiple installations side by side or remove it entirely by just removing the virtualenv directory) and does not require root privileges.
- :ref:`installation-without-virtualenv`: The alternative method of installing a Kallithea release is using standard pip. The package will be installed in the same location as all other Python packages you have ever installed. As a result, removing it is not as straightforward as with a virtualenv, as you'd have to remove its dependencies manually and make sure that they are not needed by other packages.
Regardless of the installation method you may need to make sure you have appropriate development packages installed, as installation of some of the Kallithea dependencies requires a working C compiler and libffi library headers. Depending on your configuration, you may also need to install Git and development packages for the database of your choice.
For Debian and Ubuntu, the following command will ensure that a reasonable set of dependencies is installed:
sudo apt-get install build-essential git python-pip python-virtualenv libffi-dev python-dev
For Fedora and RHEL-derivatives, the following command will ensure that a reasonable set of dependencies is installed:
sudo yum install gcc git python-pip python-virtualenv libffi-devel python-devel
Installation from repository source
To install Kallithea in a virtualenv using the stable branch of the development repository, follow the instructions below:
hg clone https://kallithea-scm.org/repos/kallithea -u stable cd kallithea virtualenv ../kallithea-venv . ../kallithea-venv/bin/activate pip install --upgrade pip setuptools pip install -e . python2 setup.py compile_catalog # for translation of the UI
You can now proceed to :ref:`setup`.
Installing a released version in a virtualenv
It is highly recommended to use a separate virtualenv for installing Kallithea. This way, all libraries required by Kallithea will be installed separately from your main Python installation and other applications and things will be less problematic when upgrading the system or Kallithea. An additional benefit of virtualenv is that it doesn't require root privileges.
Assuming you have installed virtualenv, create a new virtual environment for example, in /srv/kallithea/venv, using the virtualenv command:
virtualenv /srv/kallithea/venv
Activate the virtualenv in your current shell session and make sure the basic requirements are up-to-date by running:
. /srv/kallithea/venv/bin/activate pip install --upgrade pip setuptools
Note
You can't use UNIX sudo to source the virtualenv script; it will "activate" a shell that terminates immediately. It is also perfectly acceptable (and desirable) to create a virtualenv as a normal user.
Note
Some dependencies are optional. If you need them, install them in the virtualenv too:
pip install psycopg2 pip install python-ldap
This might require installation of development packages using your distribution's package manager.
Make a folder for Kallithea data files, and configuration somewhere on the filesystem. For example:
mkdir /srv/kallithea
Go into the created directory and run this command to install Kallithea:
pip install kallithea
Alternatively, download a .tar.gz from http://pypi.python.org/pypi/Kallithea, extract it and run:
pip install .
This will install Kallithea together with all other required Python libraries into the activated virtualenv.
You can now proceed to :ref:`setup`.
Installing a released version without virtualenv
For installation without virtualenv, 'just' use:
pip install kallithea
Note that this method requires root privileges and will install packages globally without using the system's package manager.
To install as a regular user in ~/.local, you can use:
pip install --user kallithea
You can now proceed to :ref:`setup`.
