Installing on RedHat, Fedora and CentOS¶
Hardware requirements¶
Weblate should run on all contemporary hardware without problems, the following is the minimal configuration required to run Weblate on a single host (Weblate, database and webserver):
2 GB of RAM
2 CPU cores
1 GB of storage space
The more memory the better - it is used for caching on all levels (filesystem, database and Weblate).
Many concurrent users increases the amount of needed CPU cores. For hundreds of translation components at least 4 GB of RAM is recommended.
Nota
Actual requirements for your installation of Weblate vary heavily based on the size of the translations managed in it.
Instalação¶
System requirements¶
Install the dependencies needed to build the Python modules (see Requisitos de software):
dnf install \
libxslt-devel libxml2-devel freetype-devel libjpeg-devel zlib-devel libyaml-devel \
cairo-devel pango-devel gobject-introspection-devel libacl-devel \
python3-pip python3-virtualenv python3-devel git
Install wanted optional dependencies depending on features you intend to use (see Dependências opcionais):
dnf install tesseract-langpack-eng tesseract-devel leptonica-devel
Optionally install software for running production server, see Executando servidor, Configuração de banco de dados para o Weblate, Background tasks using Celery. Depending on size of your installation you might want to run these components on dedicated servers.
The local installation instructions:
# Web server option 1: NGINX and uWSGI
dnf install nginx uwsgi uwsgi-plugin-python3
# Web server option 2: Apache with ``mod_wsgi``
dnf install apache2 apache2-mod_wsgi
# Caching backend: Redis
dnf install redis
# Database server: PostgreSQL
dnf install postgresql postgresql-contrib
# SMTP server
dnf install postfix
Python modules¶
Dica
We’re using virtualenv to install Weblate in a separate environment from your system. If you are not familiar with it, check virtualenv User Guide.
Create the virtualenv for Weblate:
virtualenv --python=python3 ~/weblate-env
Activate the virtualenv for Weblate:
. ~/weblate-env/bin/activate
Install Weblate including all dependencies:
pip install Weblate
Install database driver:
pip install psycopg2-binary
Install wanted optional dependencies depending on features you intend to use (some might require additional system libraries, check Dependências opcionais):
pip install ruamel.yaml aeidon boto3 zeep chardet tesserocr
Configuring Weblate¶
Nota
Following steps assume virtualenv used by Weblate is active (what can be
done by . ~/weblate-env/bin/activate
). In case this is not true, you will
have to specify full path to weblate command as
~/weblate-env/bin/weblate
.
Copy the file
~/weblate-env/lib/python3.7/site-packages/weblate/settings_example.py
to~/weblate-env/lib/python3.7/site-packages/weblate/settings.py
.Adjust the values in the new
settings.py
file to your liking. You can stick with shipped example for testing purposes, but you will want changes for production setup, see Ajustando a configuração.Create the database and its structure for Weblate (the example settings use PostgreSQL, check Configuração de banco de dados para o Weblate for production ready setup):
weblate migrate
Create the administrator user account and copy the password it outputs to the clipboard, and also save it for later use:
weblate createadmin
Collect static files for web server (see Executando servidor and Servindo arquivos estáticos):
weblate collectstatic
Compress JavaScript and CSS files (optional, see Comprimindo os ativos do cliente):
weblate compress
Start Celery workers. This is not necessary for development purposes, but strongly recommended otherwise. See Background tasks using Celery for more info:
~/weblate-env/lib/python3.7/site-packages/weblate/examples/celery start
Start the development server (see Executando servidor for production setup):
weblate runserver
After installation¶
Congratulations, your Weblate server is now running and you can start using it.
You can now access Weblate on
http://localhost:8000/
.Login with admin credentials obtained during installation or register with new users.
You can now run Weblate commands using weblate command when Weblate virtualenv is active, see Management commands.
You can stop the test server with Ctrl+C.
Adding translation¶
Open the admin interface (
http://localhost:8000/create/project/
) and create the project you want to translate. See Project configuration for more details.All you need to specify here is the project name and its website.
Create a component which is the real object for translation - it points to the VCS repository, and selects which files to translate. See Component configuration for more details.
The important fields here are: Component name, VCS repository address and mask for finding translatable files. Weblate supports a wide range of formats including gettext PO files, Android resource strings, iOS string properties, Java properties or Qt Linguist files, see Formatos de arquivos suportados for more details.
Once the above is completed (it can be lengthy process depending on the size of your VCS repository, and number of messages to translate), you can start translating.
