If your searx instance is public, stop here and first install :ref:`filtron reverse proxy ` and :ref:`result proxy morty `, see :ref:`installation scripts`. If already done, follow setup: *searx via filtron plus morty*. Now you have to create a configuration for the searx site. If nginx_ is new to you, the `nginx beginners guide`_ is a good starting point and the `Getting Started wiki`_ is always a good resource *to keep in the pocket*. .. tabs:: .. group-tab:: Ubuntu / debian Create configuration at ``/etc/nginx/sites-available/searx`` and place a symlink to sites-enabled: .. code:: sh sudo -H ln -s /etc/nginx/sites-available/searx /etc/nginx/sites-enabled/searx .. group-tab:: Arch Linux In the ``/etc/nginx/nginx.conf`` file, replace the configuration section named ``server``. .. group-tab:: Fedora / RHEL Create configuration at ``/etc/nginx/conf.d/searx`` and place a symlink to sites-enabled: .. tabs:: .. group-tab:: searx via filtron plus morty Use this setup, if your instance is public to the internet, compare figure: :ref:`architecture ` and :ref:`installation scripts`. 1. Configure a reverse proxy for :ref:`filtron `, listening on *localhost 4004* (:ref:`filtron route request`): .. code:: nginx location / { proxy_pass http://127.0.0.1:4004/; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Scheme $scheme; } 2. Configure reverse proxy for :ref:`morty `, listening on *localhost 3000*: .. code:: nginx location /morty { proxy_pass http://127.0.0.1:3000/; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Scheme $scheme; } Note that reverse proxy advised to be used in case of single-user or low-traffic instances. For a fully result proxification add :ref:`morty's ` **public URL** to your :origin:`searx/settings.yml`: .. code:: yaml result_proxy: # replace example.org with your server's public name url : https://example.org/morty server: image_proxy : True .. group-tab:: proxy or uWSGI Be warned, with this setup, your instance isn't :ref:`protected `. Nevertheless it is good enough for intranet usage and it is a excellent example of; *how different services can be set up*. The next example shows a reverse proxy configuration wrapping the :ref:`searx-uWSGI application `, listening on ``http = 127.0.0.1:8888``. .. code:: nginx location / { proxy_pass http://127.0.0.1:8888; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Scheme $scheme; proxy_set_header X-Script-Name /searx; proxy_buffering off; } Alternatively you can use the `uWSGI support from nginx`_ via unix sockets. For socket communication, you have to activate ``socket = /run/uwsgi/app/searx/socket`` and comment out the ``http = 127.0.0.1:8888`` configuration in your :ref:`uwsgi ini file `. The example shows a nginx virtual ``server`` configuration, listening on port 80 (IPv4 and IPv6 http://[::]:80). The uWSGI app is configured at location ``/`` by importing the `uwsgi_params`_ and passing requests to the uWSGI socket (``uwsgi_pass``). The ``server``\'s root points to the :ref:`searx-src clone ` and wraps directly the :origin:`searx/static/` content at ``location /static``. .. code:: nginx server { # replace example.org with your server's public name server_name example.org; listen 80; listen [::]:80; location / { include uwsgi_params; uwsgi_pass unix:/run/uwsgi/app/searx/socket; } root /usr/local/searx/searx-src/searx; location /static { } } If not already exists, create a folder for the unix sockets, which can be used by the searx account: .. code:: bash mkdir -p /run/uwsgi/app/searx/ sudo -H chown -R searx:searx /run/uwsgi/app/searx/ .. group-tab:: proxy at subdir URL Be warned, with these setups, your instance isn't :ref:`protected `. The examples are just here to demonstrate how to export the searx application from a subdirectory URL ``https://example.org/searx/``. .. code:: nginx location /searx { proxy_pass http://127.0.0.1:8888; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Scheme $scheme; proxy_set_header X-Script-Name /searx; proxy_buffering off; } location /searx/static { alias /usr/local/searx/searx-src/searx/static; } The ``X-Script-Name /searx`` is needed by the searx implementation to calculate relative URLs correct. The next example shows a uWSGI configuration. Since there are no HTTP headers in a (u)WSGI protocol, the value is shipped via the SCRIPT_NAME_ in the WSGI environment. .. code:: nginx location /searx/static { alias /usr/local/searx/searx-src/searx; } location /searx { uwsgi_param SCRIPT_NAME /searx; include uwsgi_params; uwsgi_pass unix:/run/uwsgi/app/searx/socket; } For searx to work correctly the ``base_url`` must be set in the :origin:`searx/settings.yml`. .. code:: yaml server: # replace example.org with your server's public name base_url : https://example.org/searx/ Restart service: .. tabs:: .. group-tab:: Ubuntu / debian .. code:: sh sudo -H systemctl restart nginx sudo -H service uwsgi restart searx .. group-tab:: Arch Linux .. code:: sh sudo -H systemctl restart nginx sudo -H systemctl restart uwsgi@searx .. group-tab:: Fedora .. code:: sh sudo -H systemctl restart nginx sudo -H touch /etc/uwsgi.d/searx.ini Disable logs ============ For better privacy you can disable nginx logs in ``/etc/nginx/nginx.conf``. .. code:: nginx http { # ... access_log /dev/null; error_log /dev/null; # ... }
