Requirements on Debian or Ubuntu

On Debian or Ubuntu, all requirements are already packaged, to install them you can use apt-get:

apt-get install python-django translate-toolkit python-git python-django-registration \
    python-whoosh python-cairo python-gtk2 python-django-south python-libravatar python-pyicu

# Optional for database backend

apt-get install python-mysqldb   # For MySQL
apt-get install python-psycopg2  # For PostgreSQL

Requirements on openSUSE

All requirements are available either directly in openSUSE or in devel:languages:python repository:

zypper install python-django python-django-registration translate-toolkit python-GitPython \
    python-whoosh python-cairo python-South python-gtk

Requirements on OSX

PyCairo and PyGtk are available to be installed using brew, all other requirements must be installed using pip as explained next. In a terminal:

brew update
brew install py2cairo pygtk

If your python was not installed using brew, make sure you have this in your .bash_profile file or executed somehow:

export PYTHONPATH="/usr/local/lib/python2.7/site-packages:$PYTHONPATH"

This configuration make available the installed libraries to python

Requirements using pip installer

Most requirements can be also installed using pip installer:

pip install -r requirements.txt

However you need to get PyCairo and PyGtk for your platform elsewhere as they do not support this easy installation method. Check their website for options for getting appropriate binaries.

Installation

Copy weblate/settings_example.py to weblate/settings.py and adjust it to match your setup. You will probably want to adjust following options:

ADMINS

List of site administrators to receive notifications when something goes wrong, for example notifications on failed merge or Django errors.

ALLOWED_HOSTS

If you are running Django 1.5 or newer, you need to set this to list of hosts your site is supposed to serve. For example:

ALLOWED_HOSTS = ['demo.weblate.org']

DATABASES

Connectivity to database server, please check Django’s documentation for more details.

Note

When using MySQL, don’t forget to create database with UTF-8 encoding:

CREATE DATABASE <dbname> CHARACTER SET utf8;

DEBUG

Disable this for production server. With debug mode enabled, Django will show backtraces in case of error to users, when you disable it, errors will go by email to ADMINS (see above).

Debug mode also slows down Weblate as Django stores much more information internally in this case.

DEFAULT_FROM_EMAIL

Email sender address for outgoing email, for example registration emails.

SERVER_EMAIL

Email used as sender address for sending emails to administrator, for example notifications on failed merge.

After your configuration is ready, you can run ./manage.py syncdb and ./manage.py migrate to create database structure. Now you should be able to create translation projects using admin interface.

In case you want to run installation non interactively, you can use ./manage.py syncdb –noinput and then create admin user using createadmin command.

You should also login to admin interface (on /admin/ URL) and adjust default site name to match your domain.

Note

If you are running version from Git, you should also regenerate locale files every time you are upgrading. You can do this by invoking script ./scripts/generate-locales.

Production setup

For production setup you should do following adjustments:

Disable debug mode

Disable Django’s debug mode by:

DEBUG = False

With debug mode Django stores all executed queries and shows users backtrackes of errors what is not desired in production setup.

Installation

Properly configure admins

Set correct admin addresses to ADMINS setting for defining who will receive mail in case something goes wrong on the server, for example:

ADMINS = (
    ('Your Name', 'your_email@example.com'),
)

See also

Installation

Set correct site name

Adjust site name in admin interface, otherwise links in RSS or registration emails will not work.

Enable indexing offloading

Enable OFFLOAD_INDEXING to prevent locking issues and improve performance.

Use powerful database engine

Use powerful database engine (SQLite is usually not good enough for production environment), for example setup for MySQL:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'weblate',
        'USER': 'weblate',
        'PASSWORD': 'weblate',
        'HOST': '127.0.0.1',
        'PORT': '',
    }
}

Enable caching

If possible, use memcache from Django by adjusting CACHES config variable, for example:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

Configure email addresses

Weblate needs to send out emails on several occasions and these emails should have correct sender address, please configure SERVER_EMAIL and DEFAULT_FROM_EMAIL to match your environment, for example:

SERVER_EMAIL = 'admin@example.org'
DEFAULT_FROM_EMAIL = 'weblate@example.org'

Allowed hosts setup

Django 1.5 and newer require ALLOWED_HOSTS to hold list of domain names your site is allowed to serve, having it empty will block any request.

Federated avatar support

By default, Weblate relies on <https://www.libravatar.org/> for avatars. When you install pyLibavatar, you will get proper support for federated avatars.

PyICU library

PyICU library is optionally used by Weblate to sort unicode strings. This way language names are properly sorted even in non-ascii languages like Japanese, Chinese or Arabic or for languages with accented letters.

Running server

Running Weblate is not different from running any other Django based application.

It is recommended to serve static files directly by your web server, you should use that for following paths:

/media
Serves media directory from Weblate.
/static/admin
Serves media files for Django admin interface (eg. /usr/share/pyshared/django/contrib/admin/media/).

Additionally you should setup rewrite rule to serve media/favicon.ico as favicon.ico.

Sample configuration for Lighttpd

The configuration for Lighttpd web server might look like following (available as examples/lighttpd.conf):

fastcgi.server = (
    "/weblate.fcgi" => (
        "main" => (
            "socket" => "/var/run/django/weblate.socket",
            "check-local" => "disable",
        )
    ),
)
alias.url = (
    "/media" => "/var/lib/django/weblate/weblate/media/",
    "/static/admin" => "/usr/share/pyshared/django/contrib/admin/static/admin/",
)

url.rewrite-once = (
    "^(/*media.*)$" => "$1",
    "^(/*static.*)$" => "$1",
    "^/*favicon\.ico$" => "/media/favicon.ico",
    "^/*robots\.txt$" => "/media/robots.txt",
    "^(/.*)$" => "/weblate.fcgi$1",
)

expire.url                  = (
    "/media/" => "access 1 months",
    "/static/" => "access 1 months",
    "/favicon.ico" => "access 1 months",
)

Sample configuration for Apache

Following configuration runs Weblate as WSGI, you need to have enabled mod_wsgi (available as examples/apache.conf):

#
# VirtualHost for weblate
#
WSGIPythonPath /usr/share/weblate
<VirtualHost *:80>
    ServerAdmin admin@image.weblate.org
    ServerName image.weblate.org

    DocumentRoot /usr/share/weblate/weblate/media/

    Alias /robots.txt /usr/share/weblate/weblate/media/robots.txt
    Alias /favicon.ico /usr/share/weblate/weblate/media/favicon.ico

    Alias /media/ /usr/share/weblate/weblate/media/
    Alias /doc/ /usr/share/doc/packages/weblate/html/
    Alias /static/admin /usr/lib/python2.7/site-packages/django/contrib/admin/static/admin/

    <Directory /usr/lib/python2.7/site-packages/django/contrib/admin/static/admin/>
        Order deny,allow
        Allow from all
    </Directory>

    <Directory /usr/share/weblate/weblate/media/>
        Order deny,allow
        Allow from all
    </Directory>

    <Directory /usr/share/doc/packages/weblate/html/>
        Order deny,allow
        Allow from all
    </Directory>

    <Directory /usr/share/weblate/weblate/examples/>
        Order deny,allow
        Allow from all
    </Directory>

    WSGIScriptAlias / /usr/share/weblate/weblate/wsgi.py
    WSGIPassAuthorization On

    <Directory /usr/share/weblate/weblate>
        <Files wsgi.py>
        Order deny,allow
        Allow from all
        </Files>
    </Directory>

</VirtualHost>

Running Weblate under path

Minimalistic configuration to serve Weblate under /weblate (you will need to include portions of above full configuration to allow access to the files). Again using mod_wsgi (also available as examples/apache-path.conf):



# Example Apache configuration for running Weblate under /weblate path

# Path to Weblate code
WSGIPythonPath /usr/share/weblate

# Path to Weblate WSGI handler
WSGIScriptAlias /weblate "/usr/share/weblate/weblate/wsgi.py"

# Aliases to serve media and static files
Alias /weblate/media/ /usr/share/weblate/weblate/media/
Alias /static/admin /usr/lib/python2.7/site-packages/django/contrib/admin/static/admin/

Additionally you will have to adjust weblate/settings.py:

URL_PREFIX = '/weblate'

Note

This is supported since Weblate 1.3.

Prebuilt appliance

Prebuilt appliance provides preconfigured Weblate running with MySQL database as backend and Apache as web server. However it comes with standard set of passwords you will want to change:

Username Password Scope Description
root linux System Administrator account, use for local or SSH login
root   MySQL MySQL administrator
weblate weblate MySQL Account in MySQL database for storing Weblate data
admin admin Weblate Weblate/Django admin user

The appliance is built using SUSE Studio and is based on openSUSE 12.2.

You should also adjust some settings to match your environment, namely:

Upgrading

Generic upgrade instructions

Changed in version 1.2: Since version 1.2 the migration is done using South module, to upgrade to 1.2, please see Version specific instructions.

Before upgrading, please check current Requirements as they might have changed.

To upgrade database structure, you should run following commands:

./manage.py syncdb
./manage.py migrate

To upgrade default set of privileges definitions (optional), run:

./manage.py setupgroups

To upgrade default set of language definitions (optional), run:

./manage.py setuplang

Version specific instructions

Upgrade from 0.5 to 0.6

On upgrade to version 0.6 you should run ./manage.py syncdb and ./manage.py setupgroups –move to setup access control as described in installation section.

Upgrade from 0.6 to 0.7

On upgrade to version 0.7 you should run ./manage.py syncdb to setup new tables and ./manage.py rebuild_index to build index for fulltext search.

Upgrade from 0.7 to 0.8

On upgrade to version 0.8 you should run ./manage.py syncdb to setup new tables, ./manage.py setupgroups to update privileges setup and ./manage.py rebuild_index to rebuild index for fulltext search.

Upgrade from 0.8 to 0.9

On upgrade to version 0.9 file structure has changed. You need to move repos and whoosh-index to weblate folder. Also running ./manage.py syncdb, ./manage.py setupgroups and ./manage.py setuplang is recommended to get latest updates of privileges and language definitions.

Upgrade from 0.9 to 1.0

On upgrade to version 1.0 one field has been added to database, you need to invoke following SQL command to adjust it:

ALTER TABLE `trans_subproject` ADD `template` VARCHAR(200);

Upgrade from 1.0 (1.1) to 1.2

On upgrade to version 1.2, the migration procedure has changed. It now uses South for migrating database. To switch to this new migration schema, you need to run following commands:

./manage.py syncdb
./manage.py migrate trans 0001 --fake
./manage.py migrate accounts 0001 --fake
./manage.py migrate lang 0001 --fake

Also please note that there are several new requirements and version 0.8 of django-registration is now being required, see Requirements for more details.

Once you have done this, you can use Generic upgrade instructions.

Upgrade from 1.2 to 1.3

Since 1.3, settings.py is not shipped with Weblate, but only example settings as settings_example.py it is recommended to use it as new base for your setup.

Upgrade from 1.4 to 1.5

Several internal modules and paths have been renamed and changed, please adjust your settings.py to match that (consult settings_example.py for correct values).

  • Many modules lost their weblate. prefix.
  • Checks were moved to submodules.
  • Locales were moved to top level directory.

The migration of database structure to 1.5 might take quite long, it is recommended to put your site offline, while the migration is going on.

Note

If you have update in same directory, stale *.pyc files might be left around and cause various import errors. To recover from this, delete all of them in Weblate’s directory, for example by find . -name '*.pyc' - delete.

Migrating from Pootle

As Weblate was originally written as replacement from Pootle, it is supported to migrate user accounts from Pootle. All you need to do is to copy auth_user table from Pootle, user profiles will be automatically created for users as they log in and they will be asked to update their settings. Alternatively you can use importusers to import dumped user credentials.
