Basic installation

Step by step installation with virtualenv. For Ubuntu, be sure to have enable universe repository.

Install packages:

Ubuntu / debian

$ sudo -H apt-get install -m \
          git build-essential
          libxslt-dev python3-dev python3-babel python3-venv \
          zlib1g-dev libffi-dev libssl-dev

Install searx:

sudo -H useradd searx --system --disabled-password -d /usr/local/searx
sudo -H usermod -a -G shadow searx
cd /usr/local/searx
sudo -H git clone https://github.com/asciimoo/searx.git searx-src
sudo -H chown searx:searx -R /usr/local/searx

Install virtualenv:

sudo -H -u searx -i
(searx)$ python3 -m venv searx-pyenv
(searx)$ echo 'source ~/searx-pyenv/bin/activate' > ~/.profile

Exit the searx bash and restart a new to install the searx dependencies:

sudo -H -u searx -i
(searx)$ cd searx-src
(searx)$ ./manage.sh update_packages

Configuration

sudo -H -u searx -i
(searx)$ cd searx-src
(searx)$ sed -i -e "s/ultrasecretkey/`openssl rand -hex 16`/g" searx/settings.yml

Edit searx/settings.yml if necessary.

Check

Start searx:

sudo -H -u searx -i
(searx)$ cd searx-src
(searx)$ python3 searx/webapp.py

Go to http://localhost:8888

If everything works fine, disable the debug option in settings.yml:

sed -i -e "s/debug : True/debug : False/g" searx/settings.yml

At this point searx is not demonized ; uwsgi allows this. You can exit the virtualenv and the searx user bash (enter exit command twice).

uwsgi

Install packages:

Ubuntu / debian

sudo -H apt-get install uwsgi uwsgi-plugin-python3

Create the configuration file /etc/uwsgi/apps-available/searx.ini with this content:

[uwsgi]

# uWSGI core
# ----------
#
# https://uwsgi-docs.readthedocs.io/en/latest/Options.html#uwsgi-core

# Who will run the code
uid = searx
gid = searx

# chdir to specified directory before apps loading
chdir = /usr/local/searx/searx-src/searx

# disable logging for privacy
disable-logging = true

# The right granted on the created socket
chmod-socket = 666

# Plugin to use and interpretor config
single-interpreter = true

# enable master process
master = true

# load apps in each worker instead of the master
lazy-apps = true

# load uWSGI plugins
plugin = python3,http

# By default the Python plugin does not initialize the GIL.  This means your
# app-generated threads will not run.  If you need threads, remember to enable
# them with enable-threads.  Running uWSGI in multithreading mode (with the
# threads options) will automatically enable threading support. This *strange*
# default behaviour is for performance reasons.
enable-threads = true

# plugin: python
# --------------
#
# https://uwsgi-docs.readthedocs.io/en/latest/Options.html#plugin-python

# load a WSGI module
module = searx.webapp

# set PYTHONHOME/virtualenv
virtualenv = /usr/local/searx/searx-pyenv

# add directory (or glob) to pythonpath
pythonpath = /usr/local/searx/searx-src


# plugin http
# -----------
#
# https://uwsgi-docs.readthedocs.io/en/latest/Options.html#plugin-http

# Native HTTP support: https://uwsgi-docs.readthedocs.io/en/latest/HTTP.html
http = 127.0.0.1:8888

Activate the uwsgi application and restart:

cd /etc/uwsgi/apps-enabled
ln -s ../apps-available/searx.ini
/etc/init.d/uwsgi restart

How to update

sudo -H -u searx -i
(searx)$ git stash
(searx)$ git pull origin master
(searx)$ git stash apply
(searx)$ ./manage.sh update_packages

Restart uwsgi:

Ubuntu / debian

sudo -H systemctl restart uwsgi

Docker

Make sure you have installed Docker. For instance, you can deploy searx like this:

docker pull wonderfall/searx
docker run -d --name searx -p $PORT:8888 wonderfall/searx

Go to http://localhost:$PORT.

See https://hub.docker.com/r/wonderfall/searx/ for more informations. It's also possible to build searx from the embedded Dockerfile.

git clone https://github.com/asciimoo/searx.git
cd searx
docker build -t whatever/searx .
