Running Searchlight API using uWSGI

The recommended way to deploy Searchlight is have a web server such as Apache or nginx to handle http requests and proxy these requests to Searchlight WSGI app running in uWSGI. Searchlight comes with some configuration templates on how to deploy the api service with Apache and uWSGI.

app.wsgi

The searchlight/api/app.wsgi file contains a WSGI application of Searchlight API service. This file is installed with Searchlight application code.

apache-searchlight.template

The searchlight/etc/apache-searchlight.template file contains a copy of Apache configuration file for Searchlight API used by devstack.

searchlight-uwsgi.ini.sample

The searchlight/etc/searchlight-uwsgi.ini.sample file is a sample configuration file for uWSGI server. Update the file to match your system configuration.

Steps to use these sample configuration files:

  1. Enable mod_proxy_uwsgi module

  • On Ubuntu install required uwsgi package sudo apt-get install libapache2-mod-proxy-uwsgi; enable using sudo a2enmod proxy, sudo a2enmod proxy_uwsgi.

  • On Fedora the required package is mod_proxy_uwsgi; enable by creating a file /etc/httpd/conf.modules.d/11-proxy_uwsgi.conf containing LoadModule proxy_uwsgi_module modules/mod_proxy_uwsgi.so

  1. On deb-based systems copy or symlink the file to /etc/apache2/sites-available/searchlight.conf. For rpm-based systems the file should go into /etc/httpd/conf.d/searchlight.conf.

  2. Enable Searchlight site. On deb-based systems:

    $ a2ensite searchlight
$ service apache2 reload

    On rpm-based systems:

    $ service httpd reload

  3. Copy searchlight/etc/searchlight-uwsgi.ini.sample to /etc/searchlight/searchlight-uwsgi.ini.

  4. Start Searchlight api using uWSGI:

    $ sudo pip install uwsgi
$ uwsgi /etc/searchlight/searchlight-uwsgi.ini
