.. _searxng filtron:
==========================
How to protect an instance
==========================
.. tip::
To protect your instance a installation of filtron (as described here) is no
longer needed, alternatively activate the :ref:`limiter plugin` in your
``settings.yml``. Note that the :ref:`limiter plugin` requires a :ref:`Redis
<settings redis>` database.
.. sidebar:: further reading
- :ref:`filtron.sh`
- :ref:`nginx searxng site`
.. _filtron: https://github.com/searxng/filtron
SearXNG depends on external search services. To avoid the abuse of these services
it is advised to limit the number of requests processed by SearXNG.
An application firewall, filtron_ solves exactly this problem. Filtron is just
a middleware between your web server (nginx, apache, ...) and searx, we describe
such infrastructures in chapter: :ref:`architecture`.
filtron & go
============
.. _Go: https://golang.org/
.. _filtron README: https://github.com/searxng/filtron/blob/master/README.md
Filtron needs Go_ installed. If Go_ is preinstalled, filtron_ is simply
installed by ``go get`` package management (see `filtron README`_). If you use
filtron as middleware, a more isolated setup is recommended. To simplify such
an installation and the maintenance of, use our script :ref:`filtron.sh`.

.. _filtron route request:
Route request through filtron
=============================
.. sidebar:: further reading
- :ref:`filtron.sh overview`
- :ref:`installation nginx`
- :ref:`installation apache`
Filtron can be started using the following command:
.. code:: sh
$ filtron -rules rules.json
It listens on ``127.0.0.1:4004`` and forwards filtered requests to
``127.0.0.1:8888`` by default.
Use it along with ``nginx`` with the following example configuration.
.. code:: nginx
# https://example.org/searx
location /searx {
proxy_pass http://127.0.0.1:4004/;
proxy_set_header Host $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 {
/usr/local/searx/searx-src/searx/static;
}
Requests are coming from port 4004 going through filtron and then forwarded to
port 8888 where a SearXNG is being run. For a complete setup see: :ref:`nginx
searxng site`.

Debian's Apache layout
----------------------
If your SearXNG 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: *SearXNG via
filtron plus morty*.
Be aware, Debian's Apache layout is quite different from the standard Apache
configuration. For details look at the apache2.README.Debian_
(``/usr/share/doc/apache2/README.Debian.gz``). Some commands you should know on
Debian:
To setup a Apache revers proxy you have to enable the *headers* and *proxy*
modules and create a `Location`_ configuration for the SearXNG site. In most
distributions you have to un-comment the lines in the main configuration file,
except in :ref:`The Debian Layout`.
* :man:`apache2ctl`: Apache HTTP server control interface
* :man:`a2enmod`, :man:`a2dismod`: switch on/off modules
* :man:`a2enconf`, :man:`a2disconf`: switch on/off configurations
* :man:`a2ensite`, :man:`a2dissite`: switch on/off sites

With ProxyPreserveHost_ the incoming ``Host`` header is passed to the proxied

Depending on what your SearXNG installation is listen, you need a http
mod_proxy_http_) or socket (mod_proxy_uwsgi_) communication to upstream.
The :ref:`installation scripts` installs by default the :ref:`reference setup
<use_default_settings.yml>` and a :ref:`uwsgi setup` that listens on a socket.
You can install and activate your own ``searxng.conf`` like shown in
:ref:`apache sites`.

RequestHeader set X-Script-Name /morty
</Location>
For a fully result proxification add :ref:`morty's <searxng 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
uWSGI support
=============
Be warned, with this setup, your instance isn't :ref:`protected <searxng
filtron>`, nevertheless it is good enough for intranet usage. In modern Linux
distributions, the `mod_proxy_uwsgi`_ is compiled into the *normal* apache
package and you need to install only the :ref:`uWSGI <searxng uwsgi>` package:
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
sudo -H apt-get install uwsgi
# Ubuntu =< 18.04
sudo -H apt-get install libapache2-mod-proxy-uwsgi
.. group-tab:: Arch Linux
.. code:: sh
sudo -H pacman -S uwsgi
.. group-tab:: Fedora / RHEL
.. code:: sh
sudo -H dnf install uwsgi
The next example shows a configuration using the `uWSGI Apache support`_ via
unix sockets and `mod_proxy_uwsgi`_.
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>`. If not
already exists, create a folder for the unix sockets, which can be used by the
SearXNG account (see :ref:`create searxng user`):
.. code:: bash
sudo -H mkdir -p /run/uwsgi/app/searx/
sudo -H chown -R searx:searx /run/uwsgi/app/searx/
If the server is public; to limit access to your intranet replace ``Allow from
all`` directive and replace ``192.168.0.0/16`` with your subnet IP/class.

Now you have to create a configuration file (``searxng.conf``) for the SearXNG
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

If your SearXNG instance is public, stop here and first install :ref:`filtron

Depending on what your SearXNG installation is listen, you need a http or socket
communication to upstream.

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 $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 <searxng 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 $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 <searxng 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 <searxng
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``.
In the ``/etc/nginx/nginx.conf`` file, in the ``server`` section add a
`include <https://nginx.org/en/docs/ngx_core_module.html#include>`_
directive:
.. 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 { }
# ...
include /etc/nginx/default.d/*.conf;
# ...
}
If not already exists, create a folder for the unix sockets, which can be
used by the SearXNG account:
Create two folders, one for the *available sites* and one for the *enabled sites*:
.. code:: bash
mkdir -p /run/uwsgi/app/searx/
sudo -H chown -R searx:searx /run/uwsgi/app/searx/
mkdir -p /etc/nginx/default.d
mkdir -p /etc/nginx/default.apps-available
.. group-tab:: \.\. at subdir URL
Create configuration at ``/etc/nginx/default.apps-available`` and place a
symlink to ``default.d``:
Be warned, with these setups, your instance isn't :ref:`protected <searxng
filtron>`. The examples are just here to demonstrate how to export the
SearXNG application from a subdirectory URL ``https://example.org/searx/``.
.. code:: bash
.. code:: nginx
sudo -H ln -s /etc/nginx/default.apps-available/searxng.conf \
/etc/nginx/default.d/searxng.conf
# https://hostname.local/searx
.. group-tab:: Fedora / RHEL
location /searx {
proxy_pass http://127.0.0.1:8888;
Create a folder for the *available sites*:
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;
}
.. code:: bash
location /searx/static/ {
alias /usr/local/searx/searx-src/searx/static/;
}
mkdir -p /etc/nginx/default.apps-available
The ``X-Script-Name /searx`` is needed by the SearXNG 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.
Create configuration at ``/etc/nginx/default.apps-available`` and place a
symlink to ``conf.d``:
.. code:: nginx
.. code:: bash
# https://hostname.local/searx
sudo -H ln -s /etc/nginx/default.apps-available/searxng.conf \
/etc/nginx/conf.d/searxng.conf
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 SearXNG 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/

For the installation procedure, use a *sudoer* login to run the scripts. If
you install from ``root``, take into account that the scripts are creating a
``searxng`` user. In the installation procedure this new created user do
need read access to the clone of searx, which is not the case if you clone
into a folder below ``/root``!

How uWSGI is implemented by distributors is different. uWSGI itself

How uWSGI is implemented by distributors varies. The uWSGI project itself
recommends two methods:
There is one `systemd unit template`_ and one `uwsgi ini file`_ per uWSGI-app
placed at dedicated locations. Take archlinux and a searxng.ini as example::
1. `systemd.unit`_ template file as described here `One service per app in systemd`_:
unit template --> /usr/lib/systemd/system/uwsgi@.service
uwsgi ini files --> /etc/uwsgi/searxng.ini
There is one `systemd unit template`_ on the system installed and one `uwsgi
ini file`_ per uWSGI-app placed at dedicated locations. Take archlinux and a
``searxng.ini`` as example::
The SearXNG app can be maintained as know from common systemd units::
systemd template unit: /usr/lib/systemd/system/uwsgi@.service
contains: [Service]
ExecStart=/usr/bin/uwsgi --ini /etc/uwsgi/%I.ini
systemctl enable uwsgi@searx
systemctl start uwsgi@searx
systemctl restart uwsgi@searx
systemctl stop uwsgi@searx
SearXNG application: /etc/uwsgi/searxng.ini

from common systemd units:
.. code:: sh

$ systemctl start uwsgi@searxng
$ systemctl restart uwsgi@searxng
$ systemctl stop uwsgi@searxng
2. The `uWSGI Emperor`_ which fits for maintaining a large range of uwsgi
apps and there is a `Tyrant mode`_ to secure multi-user hosting.
The Emperor mode is a special uWSGI instance that will monitor specific
events. The Emperor mode (service) is started by a (common, not template)
systemd unit. The Emperor service will scan specific directories for `uwsgi
ini file`_\s (also know as *vassals*). If a *vassal* is added, removed or the
timestamp is modified, a corresponding action takes place: a new uWSGI
instance is started, reload or stopped. Take Fedora and a searxng.ini as

Commands recognized by init.d script
====================================
My experience is, that this command is a bit buggy.
You can issue to init.d script following commands:
* start | starts daemon
* stop | stops daemon
* reload | sends to daemon SIGHUP signal
* force-reload | sends to daemon SIGTERM signal
* restart | issues 'stop', then 'start' commands
* status | shows status of daemon instance (running/not running)

'status' command must be issued with exactly one argument: '<confname>'.

Controlling specific instances of uWSGI
=======================================
Create the configuration ini-file according to your distribution (see below) and
restart the uwsgi application.
You could control specific instance(s) by issuing:
SYSTEMCTL_SKIP_REDIRECT=1 service uwsgi <command> <confname> <confname>...
where:
* <command> is one of 'start', 'stop' etc.
* <confname> is the name of configuration file (without extension)

started:

Pitfalls of the Tyrant mode
===========================
The implementation of the process owners and groups in the `Tyrant mode`_ is
somewhat unusual and requires special consideration. In `Tyrant mode`_ mode the
Emperor will run the vassal using the UID/GID of the vassal configuration file
(user and group of the app ``.ini`` file).
.. _#2099@uWSGI: https://github.com/unbit/uwsgi/issues/2099
.. _#752@uWSGI: https://github.com/unbit/uwsgi/pull/752
.. _#2425uWSGI: https://github.com/unbit/uwsgi/issues/2425
Without option ``emperor-tyrant-initgroups=true`` in ``/etc/uwsgi.ini`` the
process won't get the additional groups, but this option is not available in
2.0.x branch (see `#2099@uWSGI`_) the feature `#752@uWSGI`_ has been merged (on
Oct. 2014) to the master branch of uWSGI but had never been released; the last
major release is from Dec. 2013, since the there had been only bugfix releases
(see `#2425uWSGI`_). To shorten up:
**In Tyrant mode, there is no way to get additional groups, and the uWSGI
process misses additional permissions that may be needed.**
By example, on Fedora (RHEL): If you try to install a redis DB with socket
communication and you want to connect from the SearXNG uWSGI, you will see a
*Permission denied* in the log of your instance::
ERROR:searx.shared.redis: [searxng (993)] can't connect redis DB ...
ERROR:searx.shared.redis: Error 13 connecting to unix socket: /usr/local/searxng-redis/run/redis.sock. Permission denied.
ERROR:searx.plugins.limiter: init limiter DB failed!!!
Even if your *searxng* user of the uWSGI process is added to additional groups
to give access to the socket from the redis DB::
$ groups searxng
searxng : searxng searxng-redis
To see the effective groups of the uwsgi process, you have to look at the status
of the process, by example::
$ ps -aef | grep '/usr/sbin/uwsgi --ini searxng.ini'
searxng 93 92 0 12:43 ? 00:00:00 /usr/sbin/uwsgi --ini searxng.ini
searxng 186 93 0 12:44 ? 00:00:01 /usr/sbin/uwsgi --ini searxng.ini
Here you can see that the additional "Groups" of PID 186 are unset (missing gid
of ``searxng-redis``)::
$ cat /proc/186/task/186/status
...
Uid: 993 993 993 993
Gid: 993 993 993 993
FDSize: 128

The :ref:`installation basic` is good enough for intranet usage and it is a
excellent illustration of *how a SearXNG instance is build up*. If you place your
instance public to the internet you should really consider to install a
:ref:`filtron reverse proxy <filtron.sh>` and for privacy a :ref:`result proxy
<morty.sh>` is mandatory.
Therefore, if you do not have any special preferences, its recommend to use the
:ref:`installation docker` or the `Installation scripts`_ from our :ref:`tooling
box <toolboxing>` as described below.
.. _installation scripts:
Installation scripts
====================
.. sidebar:: Update OS first!
To avoid unwanted side effects, update your OS before installing SearXNG.
The following will install a setup as shown in :ref:`architecture`. First you
need to get a clone. The clone is only needed for the installation procedure
and some maintenance tasks (alternatively you can create your own fork).
For the installation procedure, use a *sudoer* login to run the scripts. If you
install from ``root``, take into account that the scripts are creating a
``searx``, a ``filtron`` and a ``morty`` user. In the installation procedure
these new created users do need read access to the clone of searx, which is not
the case if you clone into a folder below ``/root``.
.. code:: bash
$ cd ~/Downloads
$ git clone https://github.com/searxng/searxng.git searxng
$ cd searxng
.. sidebar:: further read
- :ref:`toolboxing`

**Install** :ref:`SearXNG service <searx.sh>`
This installs SearXNG as described in :ref:`installation basic`.
.. code:: bash
$ sudo -H ./utils/searx.sh install all
**Install** :ref:`filtron reverse proxy <filtron.sh>`
.. code:: bash
$ sudo -H ./utils/filtron.sh install all
**Install** :ref:`result proxy <morty.sh>`
.. code:: bash
$ sudo -H ./utils/morty.sh install all
If all services are running fine, you can add it to your HTTP server:
**Install** HTTP
- :ref:`installation apache`
- :ref:`installation nginx`
**Install** :ref:`external plugins <dev plugin>`
Use SearXNG's ``shell`` to install external plugins. In the example below we
install the SearXNG plugins from **The Green Web Foundation** `[ref]
<https://www.thegreenwebfoundation.org/news/searching-the-green-web-with-searx/>`__:
.. code:: bash
$ sudo -H ./utils/searx.sh shell
// exit with [CTRL-D]
(searx-pyenv) searx@ryzen:~$ pip install git+https://github.com/return42/tgwf-searx-plugins
In the :ref:`settings.yml` activate the ``plugins:`` section and add module
``only_show_green_results`` from tgwf-searx-plugins.
.. code:: yaml
plugins:
- only_show_green_results
.. _git stash: https://git-scm.com/docs/git-stash
.. tip::
About script's installation options have a look at chapter :ref:`toolboxing
setup`. How to brand your instance see chapter :ref:`settings global`. To
*stash* your instance's setup, `git stash`_ your clone's :origin:`.config.sh`

.. _morty's README: https://github.com/asciimoo/morty
By default SearXNG can only act as an image proxy for result images, but it is
possible to proxify all the result URLs with an external service, morty_.
To use this feature, morty has to be installed and activated in SearXNG's
``settings.yml``. Add the following snippet to your ``settings.yml`` and
restart searx:
.. code:: yaml
result_proxy:
url : http://127.0.0.1:3000/
key : !!binary "insert_your_morty_proxy_key_here"
Note that the example above (``http://127.0.0.1:3000``) is only for single-user
instances without a HTTP proxy. If your morty service is public, the url is the
address of the reverse proxy (e.g ``https://example.org/morty``).
For more information about *result proxy* have a look at *"SearXNG via filtron
plus morty"* in the :ref:`nginx <nginx searxng via filtron plus morty>` and
:ref:`apache <apache searxng via filtron plus morty>` sections.
``url``
Is the address of the running morty service.

Is an optional argument, see `morty's README`_ for more information.

script :origin:`utils/searxng.sh`.
Install
=======
In most cases you will install SearXNG simply by running the command:
.. code:: bash
sudo -H ./utils/searx.sh install all
The installation is described in chapter :ref:`installation basic`.
.. _searxng.sh overview:
Overview
========
The ``--help`` output of the script is largely self-explanatory:
.. program-output:: ../utils/searxng.sh --help
