.. _installation: ========================== Installation on Unix/Linux ========================== **Kallithea** is written entirely in Python_ and requires Python version 2.6 or higher. Python 3.x is currently not supported. There are several ways to install Kallithea: - :ref:`installation-source`: The Kallithea development repository is stable and can be used in production. In fact, the Kallithea maintainers do use it in production. The advantage of installation from source and regularly updating it is that you take advantage of the most recent improvements, which is particularly useful because Kallithea is evolving rapidly. - :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. .. _installation-source: Installation from repository source ----------------------------------- To install Kallithea from source in a virtualenv, follow the instructions below:: hg clone https://kallithea-scm.org/repos/kallithea cd kallithea virtualenv ../kallithea-venv source ../kallithea-venv/bin/activate python setup.py develop python setup.py compile_catalog # for translation of the UI You can now proceed to :ref:`setup`. To upgrade, simply update the repository with ``hg pull -u`` and restart the server. .. _installation-virtualenv: 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 by running:: source /srv/kallithea/venv/bin/activate .. 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. - 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:: python setup.py install - This will install Kallithea together with pylons_ and all other required python libraries into the activated virtualenv. You can now proceed to :ref:`setup`. .. _installation-without-virtualenv: 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`. Upgrading Kallithea from Python Package Index (PyPI) ----------------------------------------------------- .. note:: It is strongly recommended that you **always** perform a database and configuration backup before doing an upgrade. These directions will use '{version}' to note that this is the version of Kallithea that these files were used with. If backing up your Kallithea instance from version 0.1 to 0.2, the ``my.ini`` file could be backed up to ``my.ini.0-1``. If using a SQLite database, stop the Kallithea process/daemon/service, and then make a copy of the database file:: service kallithea stop cp kallithea.db kallithea.db.{version} Back up your configuration file:: cp my.ini my.ini.{version} Ensure that you are using the Python virtual environment that you originally installed Kallithea in by running:: pip freeze This will list all packages installed in the current environment. If Kallithea isn't listed, activate the correct virtual environment:: source /srv/kallithea/venv/bin/activate Once you have verified the environment you can upgrade Kallithea with:: pip install --upgrade kallithea Then run the following command from the installation directory:: paster make-config Kallithea my.ini This will display any changes made by the new version of Kallithea to your current configuration. It will try to perform an automerge. It is recommended that you recheck the content after the automerge. .. note:: Please always make sure your .ini files are up to date. Errors can often be caused by missing parameters added in new versions. It is also recommended that you rebuild the whoosh index after upgrading since the new whoosh version could introduce some incompatible index changes. Please read the changelog to see if there were any changes to whoosh. The final step is to upgrade the database. To do this simply run:: paster upgrade-db my.ini This will upgrade the schema and update some of the defaults in the database, and will always recheck the settings of the application, if there are no new options that need to be set. .. note:: The DB schema upgrade library has some limitations and can sometimes fail if you try to upgrade from older major releases. In such a case simply run upgrades sequentially, e.g., upgrading from 0.1.X to 0.3.X should be done like this: 0.1.X. > 0.2.X > 0.3.X You can always specify what version of Kallithea you want to install for example in pip `pip install Kallithea==0.2` You may find it helpful to clear out your log file so that new errors are readily apparent:: echo > kallithea.log Once that is complete, you may now start your upgraded Kallithea Instance:: service kallithea start Or:: paster serve /srv/kallithea/my.ini .. note:: If you're using Celery, make sure you restart all instances of it after upgrade. .. _virtualenv: http://pypi.python.org/pypi/virtualenv .. _Python: http://www.python.org/ .. _pylons: http://www.pylonsproject.org/
