.. _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

For a fully result proxification add :ref:`morty's <searxng morty>` **public
URL** to your :origin:`searx/settings.yml`:
.. code:: yaml

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.

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/

Installation Script
===================
.. sidebar:: Update the OS first!
To avoid unwanted side effects, update your OS before installing SearXNG.

the installation procedure and some maintenance tasks.
.. sidebar:: further read
- :ref:`toolboxing`
Jump to a folder that is readable by *others* and start to clone SearXNG,
alternatively you can create your own fork and clone from there.
.. code:: bash
$ cd ~/Downloads
$ git clone https://github.com/searxng/searxng.git searxng
$ cd searxng
.. sidebar:: further read

To install a SearXNG :ref:`reference setup <use_default_settings.yml>`
including a :ref:`uWSGI setup <architecture uWSGI>` as described in the
:ref:`installation basic` and in the :ref:`searxng uwsgi` section type:
.. code:: bash
$ sudo -H ./utils/searxng.sh install all
.. attention::
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 does
need read access to the cloned SearXNG repository, which is not the case if you clone
it into a folder below ``/root``!

HTTP server. We do not have any preferences for the HTTP server, you can use
whatever you prefer.
We use caddy in our :ref:`docker image <installation docker>` and we have
implemented installation procedures for:

If you have a searx installation on your sever and want to switch to SearXNG,
you need to uninstall searx first. If you have an old searx docker installation
replace your docker image / see :ref:`installation docker`.
If your searx instance was installed *"Step by step"* or by the *"Installation
scripts"*, you need to undo the installation procedure completely. If you have
morty & filtron installed, it is recommended to uninstall these services also.
In case of scripts, to uninstall use the scripts from the origin you installed
searx from.
If you have removed the old searx installation, clone from SearXNG and and start
with your installation procedure (e.g. :ref:`installation scripts`):
.. code:: bash
$ cd ~/Downloads
$ git clone https://github.com/searxng/searxng.git searxng
$ cd searxng
$ ...
``.config.sh``
==============
Please take into account; SearXNG has normalized ``.config.sh`` with
``settings.yml`` and some of the environment settings has been removed from or
renamed in the ``.config.sh``:
- :patch:`[mod] normalize .config.sh with settings.yml <f61c918d>`
- :patch:`[fix] ./utils/filtron.sh - FILTRON_TARGET from YAML settings <7196a9b5>`
- :patch:`SearXNG: SEARXNG_SETTINGS_PATH <253b8503>`
Check after Installation
========================
Once you have done your installation, you can run a SearXNG *check* procedure,
to see if there are some left overs. In this example there exists a *old*
``/etc/searx/settings.yml``::
$ sudo -H ./utils/searx.sh install check

Origin uWSGI
============
How uWSGI is implemented by distributors is different. uWSGI itself
recommend two methods
.. _Tyrant mode:
https://uwsgi-docs.readthedocs.io/en/latest/Emperor.html#tyrant-mode-secure-multi-user-hosting
`systemd.unit`_ template files as described here `One service per app in systemd`_.
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

The `uWSGI Emperor`_ mode which fits for maintaining a large range of uwsgi apps.
The SearXNG app (template ``/etc/uwsgi/%I.ini``) can be maintained as known
from common systemd units:
.. code:: sh
$ systemctl enable uwsgi@searxng
$ 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
example::

Distributors
============
The `uWSGI Emperor`_ mode and `systemd unit template`_ is what the distributors
mostly offer their users, even if they differ in the way they implement both
modes and their defaults. Another point they might differ is the packaging of
modes and their defaults. Another point they might differ in is the packaging of
plugins (if so, compare :ref:`install packages`) and what the default python
interpreter is (python2 vs. python3).
Fedora starts a Emperor by default, while archlinux does not start any uwsgi
service by default. Worth to know; debian (ubuntu) follow a complete different
approach. *debian*: your are familiar with the apache infrastructure? .. they
do similar for the uWSGI infrastructure (with less comfort), the folders are::
While archlinux does not start a uWSGI service by default, Fedora (RHEL) starts

approach, read see :ref:`Debian's uWSGI layout`.

could control specific instance(s) by issuing::
More details can be found in the uwsgi.README.Debian_

Debian:

.. code:: none
sudo -H service uwsgi start searx
sudo -H service uwsgi stop searx
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)
.. _uwsgi configuration:
'status' command must be issued with exactly one argument: '<confname>'.
Alltogether
===========
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:
SYSTEMCTL_SKIP_REDIRECT=1 service uwsgi start hello

Pitfalls of the Tyrant mode
===========================
The implementation of the process owners and groups in the `Tyrant mode`_ is

(user and group of the app ``.ini`` file).

.. _#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.**
For example on Fedora (RHEL): If you try to install a redis DB with socket
communication and you want to connect to it 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

- :ref:`installation docker`
- :ref:`installation scripts`
- :ref:`installation basic`
The :ref:`installation basic` is good enough for intranet usage and it is a

The :ref:`installation basic` is an excellent illustration of *how a SearXNG

special preferences, its recommend to use the :ref:`installation docker` or the
:ref:`installation scripts`.
Therefore, if you do not have any special preferences, its recommend to use the

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

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>`

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`
file .
SearXNG is growing rapidly, you should regularly read our :ref:`migrate and

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

$ sudo -H ./utils/morty.sh inspect service
- Bot protection has been switched from filtron to SearXNG's :ref:`limiter
<limiter>`, this requires a :ref:`Redis <settings redis>` database.
- The image proxy morty is no longer needed, it has been replaced by the
:ref:`image proxy <image_proxy>` from SearXNG.
- To save bandwith :ref:`cache busting <static_use_hash>` has been implemented.
To get in use, the ``static-expires`` needs to be set in the :ref:`uwsgi
setup`.
To stay tuned and get in use of the new features, instance maintainers have to
update the SearXNG code regularly (see :ref:`update searxng`). As the above
examples show, this is not always enough, sometimes services have to be set up
or reconfigured and sometimes services that are no longer needed should be
uninstalled.
.. hint::
First of all: SearXNG is installed by the script :ref:`searxng.sh`. If you
have old filtron, morty or searx setup you should consider complete
uninstall/reinstall.
remove obsolete services
------------------------
If your searx instance was installed *"Step by step"* or by the *"Installation
scripts"*, you need to undo the installation procedure completely. If you have
morty & filtron installed, it is recommended to uninstall these services also.
In case of scripts, to uninstall use the scripts from the origin you installed
searx from or try::
$ sudo -H ./utils/filtron.sh remove all
$ sudo -H ./utils/morty.sh remove all
$ sudo -H ./utils/searx.sh remove all
.. hint::
If you are migrate from searx take into account that the ``.config.sh`` is no
longer used.
Check after Installation
------------------------
Once you have done your installation, you can run a SearXNG *check* procedure,
to see if there are some left overs. In this example there exists a *old*
``/etc/searx/settings.yml``::
$ sudo -H ./utils/searxng.sh instance check
SearXNG checks

To simplify installation and maintenance of a filtron instance you can use the
script :origin:`utils/filtron.sh`. In most cases you will install filtron_
simply by running the command:
.. code:: bash
sudo -H ./utils/filtron.sh install all
The script adds a ``${SERVICE_USER}`` (default:``filtron``) and installs filtron_
into this user account:
#. Create a separated user account (``filtron``).
#. Download and install Go_ binary in user's $HOME (``~filtron``).
#. Install filtron with the package management from Go_ (``go get -v -u
github.com/searxng/filtron``)
#. Setup a proper rule configuration :origin:`[ref]

Common command environments
===========================
Common commands & environment
=============================
Scripts to maintain services often dispose of common commands and environments.
``shell`` : command
Opens a shell from the service user ``${SERVICE_USSR}``, very helpful for
troubleshooting.
``inspect service`` : command
Shows status and log of the service, most often you have a option to enable
more verbose debug logs. Very helpful for debugging, but be careful not to
enable debugging in a production environment!
The scripts in our tooling box often dispose of common environments:
``FORCE_TIMEOUT`` : environment
Sets timeout for interactive prompts. If you want to run a script in batch
job, with defaults choices, set ``FORCE_TIMEOUT=0``. By example; to install a
reverse proxy for filtron on all containers of the :ref:`SearXNG suite
<lxc-searx.env>` use ::
SearXNG server and nginx proxy on all containers of the :ref:`SearXNG suite
