Installation
============
.. contents::
:depth: 3
Basic installation
------------------
Step by step installation for Debian/Ubuntu with virtualenv. For Ubuntu, be sure to have enable universe repository.
Install packages:
.. code:: sh
sudo apt-get install git build-essential libxslt-dev python-dev python-virtualenv python-pybabel zlib1g-dev libffi-dev libssl-dev
Install searx:
.. code:: sh
cd /usr/local
sudo git clone https://github.com/asciimoo/searx.git
sudo useradd searx -d /usr/local/searx
sudo chown searx:searx -R /usr/local/searx
Install dependencies in a virtualenv:
.. code:: sh
sudo -u searx -i
cd /usr/local/searx
virtualenv searx-ve
. ./searx-ve/bin/activate
./manage.sh update_packages
Configuration
-------------
.. code:: sh
sed -i -e "s/ultrasecretkey/`openssl rand -hex 16`/g" searx/settings.yml
Edit searx/settings.yml if necessary.
Check
-----
Start searx:
.. code:: sh
python searx/webapp.py
Go to http://localhost:8888
If everything works fine, disable the debug option in settings.yml:
.. code:: sh
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:
.. code:: sh
sudo apt-get install uwsgi uwsgi-plugin-python
Create the configuration file /etc/uwsgi/apps-available/searx.ini with
this content:
::
[uwsgi]
# Who will run the code
uid = searx
gid = searx
# disable logging for privacy
disable-logging = true
# Number of workers (usually CPU count)
workers = 4
# The right granted on the created socket
chmod-socket = 666
# Plugin to use and interpretor config
single-interpreter = true
master = true
plugin = python
# Module to import
module = searx.webapp
# Virtualenv and python path
virtualenv = /usr/local/searx/searx-ve/
pythonpath = /usr/local/searx/
chdir = /usr/local/searx/searx/
Activate the uwsgi application and restart:
.. code:: sh
cd /etc/uwsgi/apps-enabled
ln -s ../apps-available/searx.ini
/etc/init.d/uwsgi restart
Web server
----------
with nginx
^^^^^^^^^^
If nginx is not installed (uwsgi will not work with the package
nginx-light):
.. code:: sh
sudo apt-get install nginx
Hosted at /
"""""""""""
Create the configuration file /etc/nginx/sites-available/searx with this
content:
.. code:: nginx
server {
listen 80;
server_name searx.example.com;
root /usr/local/searx;
location / {
include uwsgi_params;
uwsgi_pass unix:/run/uwsgi/app/searx/socket;
}
}
Restart service:
.. code:: sh
sudo service nginx restart
sudo service uwsgi restart
from subdirectory URL (/searx)
""""""""""""""""""""""""""""""
Add this configuration in the server config file
/etc/nginx/sites-enabled/default:
.. code:: nginx
location = /searx { rewrite ^ /searx/; }
location /searx {
try_files $uri @searx;
}
location @searx {
uwsgi_param SCRIPT_NAME /searx;
include uwsgi_params;
uwsgi_modifier1 30;
uwsgi_pass unix:/run/uwsgi/app/searx/socket;
}
OR
using reverse proxy
(Please, note that reverse proxy advised to be used in case of single-user or low-traffic instances.)
.. 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;
}
Enable base\_url in searx/settings.yml
::
base_url : http://your.domain.tld/searx/
Restart service:
.. code:: sh
sudo service nginx restart
sudo service uwsgi restart
disable logs
~~~~~~~~~~~~
for better privacy you can disable nginx logs about searx.
how to proceed: below ``uwsgi_pass`` in
/etc/nginx/sites-available/default add
::
access_log /dev/null;
error_log /dev/null;
Restart service:
.. code:: sh
sudo service nginx restart
with apache
^^^^^^^^^^^
Add wsgi mod:
.. code:: sh
sudo apt-get install libapache2-mod-uwsgi
sudo a2enmod uwsgi
Add this configuration in the file /etc/apache2/apache2.conf:
.. code:: apache
<Location />
Options FollowSymLinks Indexes
SetHandler uwsgi-handler
uWSGISocket /run/uwsgi/app/searx/socket
</Location>
Note that if your instance of searx is not at the root, you should
change ``<Location />`` by the location of your instance, like
``<Location /searx>``.
Restart Apache:
.. code:: sh
sudo /etc/init.d/apache2 restart
disable logs
""""""""""""
For better privacy you can disable Apache logs.
WARNING: not tested
WARNING: you can only disable logs for the whole (virtual) server not
for a specific path.
Go back to /etc/apache2/apache2.conf and above ``<Location />`` add:
.. code:: apache
CustomLog /dev/null combined
Restart Apache:
.. code:: sh
sudo /etc/init.d/apache2 restart
How to update
-------------
.. code:: sh
cd /usr/local/searx
sudo -u searx -i
. ./searx-ve/bin/activate
git stash
git pull origin master
git stash apply
./manage.sh update_packages
sudo service uwsgi restart
Docker
------
Make sure you have installed Docker. For instance, you can deploy searx like this:
.. code:: sh
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.
.. code:: sh
git clone https://github.com/asciimoo/searx.git
cd searx
docker build -t whatever/searx .
