The nginx HTTP server
=====================
If nginx_ is not installed (uwsgi will not work with the package nginx-light),
install it now.
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
sudo -H apt-get install nginx
.. group-tab:: Arch Linux
.. code-block:: sh
sudo -H pacman -S nginx-mainline
sudo -H systemctl enable nginx
sudo -H systemctl start nginx
.. group-tab:: Fedora / RHEL
.. code-block:: sh
sudo -H dnf install nginx
sudo -H systemctl enable nginx
sudo -H systemctl start nginx
Now at http://localhost you should see a *Welcome to nginx!* page, on Fedora you
see a *Fedora Webserver - Test Page*. The test page comes from the default
`nginx server configuration`_. How this default intro site is configured,
depends on the linux distribution:
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
less /etc/nginx/nginx.conf
there is a line including site configurations from:
.. code:: nginx
include /etc/nginx/sites-enabled/*;
.. group-tab:: Arch Linux
.. code-block:: sh
less /etc/nginx/nginx.conf
in there is a configuration section named ``server``:
.. code-block:: nginx
server {
listen 80;
server_name localhost;
# ...
}
.. group-tab:: Fedora / RHEL
.. code-block:: sh
less /etc/nginx/nginx.conf
there is a line including site configurations from:
.. code:: nginx
include /etc/nginx/conf.d/*.conf;
.. _nginx searx site:
A nginx searx site
==================
.. sidebar:: public to the internet?
If your searx instance is public, stop here and first install :ref:`filtron
reverse proxy <filtron.sh>` and :ref:`result proxy morty <morty.sh>`, 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:
.. _nginx searx via filtron plus morty:
.. tabs::
.. group-tab:: searx via filtron plus morty
Use this setup, if your instance is public to the internet, compare
figure: :ref:`architecture <arch public>` and :ref:`installation scripts`.
1. Configure a reverse proxy for :ref:`filtron <filtron.sh>`, listening on
*localhost 4004* (:ref:`filtron route request`):
.. code:: nginx
# https://example.org/searx
location /searx {
proxy_pass http://127.0.0.1:4004/;
proxy_set_header Host $http_host;
proxy_set_header Connection $http_connection;
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;
proxy_set_header X-Script-Name /searx;
}
location /searx/static {
alias /usr/local/searx/searx-src/searx/static;
}
2. Configure reverse proxy for :ref:`morty <searx morty>`, listening on
*localhost 3000*:
.. code:: nginx
# https://example.org/morty
location /morty {
proxy_pass http://127.0.0.1:3000/;
proxy_set_header Host $http_host;
proxy_set_header Connection $http_connection;
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;
}
For a fully result proxification add :ref:`morty's <searx morty>` **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
key : !!binary "insert_your_morty_proxy_key_here"
server:
image_proxy : True
.. group-tab:: proxy or uWSGI
Be warned, with this setup, your instance isn't :ref:`protected <searx
filtron>`. 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 <uwsgi configuration>`, listening on ``http =
127.0.0.1:8888``.
.. code:: nginx
# https://hostname.local/
location / {
proxy_pass http://127.0.0.1:8888;
proxy_set_header Host $host;
proxy_set_header Connection $http_connection;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Scheme $scheme;
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 <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 hostname.local with your server's name
server_name hostname.local;
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:: \.\. at subdir 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 ``https://example.org/searx/``.
.. code:: nginx
# https://hostname.local/searx
location /searx {
proxy_pass http://127.0.0.1:8888;
proxy_set_header Host $host;
proxy_set_header Connection $http_connection;
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
# https://hostname.local/searx
location /searx {
uwsgi_param SCRIPT_NAME /searx;
include uwsgi_params;
uwsgi_pass unix:/run/uwsgi/app/searx/socket;
}
location /searx/static {
alias /usr/local/searx/searx-src/searx;
}
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;
# ...
}
