Enable ``base_url`` in :origin:`searx/settings.yml`
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 <uwsgi
configuration>`.
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 <searx-src>` and wraps directly the
:origin:`searx/static/` content at ``location /static``.
.. code:: nginx
server {
# replace searx.example.com with your server's public name
server_name searx.example.com;
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:: subdirectory URL
Be warned, with these setups, your Instance isn't :ref:`protected <searx
filtron>`. The examples are just here to demonstrate how to export the
searx application from a subdirectory URL
http://searx.example.com/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`.
