The apache HTTP server
======================
If Apache_ is not installed, install it now. If apache_ is new to you, the
`Getting Started`_, `Configuration Files`_ and `Terms Used to Describe
Directives`_ documentation gives first orientation. There is also a list of
`Apache directives`_ *to keep in the pocket*.
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
sudo -H apt-get install apache2
.. group-tab:: Arch Linux
.. code:: sh
sudo -H pacman -S apache
sudo -H systemctl enable httpd
sudo -H systemctl start http
.. group-tab:: Fedora / RHEL
.. code:: sh
sudo -H dnf install httpd
sudo -H systemctl enable httpd
sudo -H systemctl start httpd
Now at http://localhost you should see any kind of *Welcome* or *Test* page.
How this default intro site is configured, depends on the linux distribution
(compare `Apache directives`_).
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
less /etc/apache2/sites-enabled/000-default.conf
In this file, there is a line setting the `DocumentRoot`_ directive:
.. code:: apache
DocumentRoot /var/www/html
And the *welcome* page is the HTML file at ``/var/www/html/index.html``.
.. group-tab:: Arch Linux
.. code:: sh
less /etc/httpd/conf/httpd.conf
In this file, there is a line setting the `DocumentRoot`_ directive:
.. code:: apache
DocumentRoot "/srv/http"
<Directory "/srv/http">
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
The *welcome* page of Arch Linux is a page showing directory located at
``DocumentRoot``. This is *directory* page is generated by the Module
`mod_autoindex <https://httpd.apache.org/docs/2.4/mod/mod_autoindex.html>`_:
.. code:: apache
LoadModule autoindex_module modules/mod_autoindex.so
...
Include conf/extra/httpd-autoindex.conf
.. group-tab:: Fedora / RHEL
.. code:: sh
less /etc/httpd/conf/httpd.conf
In this file, there is a line setting the ``DocumentRoot`` directive:
.. code:: apache
DocumentRoot "/var/www/html"
...
<Directory "/var/www">
AllowOverride None
# Allow open access:
Require all granted
</Directory>
On fresh installations, the ``/var/www`` is empty and the *default
welcome page* is shown, the configuration is located at::
less /etc/httpd/conf.d/welcome.conf
.. _apache searx site:
Apache Reverse Proxy
====================
.. 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*.
To setup a Apache revers proxy you have to enable the *headers* and *proxy*
modules and create a `Location`_ configuration for the searx site. In most
distributions you have to un-comment the lines in the main configuration file,
except in :ref:`The Debian Layout`.
.. tabs::
.. group-tab:: Ubuntu / debian
In the Apache setup, enable headers and proxy modules:
.. code:: sh
sudo -H a2enmod headers
sudo -H a2enmod proxy
sudo -H a2enmod proxy_http
In :ref:`The Debian Layout` you create a ``searx.conf`` with the
``<Location /searx >`` directive and save this file in the *sites
available* folder at ``/etc/apache2/sites-available``. To enable the
``searx.conf`` use :man:`a2ensite`:
.. code:: sh
sudo -H a2ensite searx.conf
.. group-tab:: Arch Linux
In the ``/etc/httpd/conf/httpd.conf`` file, activate headers and proxy
modules (LoadModule_):
.. code:: apache
FIXME needs test
LoadModule headers_module modules/mod_headers.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
.. group-tab:: Fedora / RHEL
In the ``/etc/httpd/conf/httpd.conf`` file, activate headers and proxy
modules (LoadModule_):
.. code:: apache
FIXME needs test
LoadModule headers_module modules/mod_headers.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
With ProxyPreserveHost_ the incoming Host HTTP request header is passed to the
proxied host.
.. _apache 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:: apache
<Location /searx >
# SetEnvIf Request_URI "/searx" dontlog
# CustomLog /dev/null combined env=dontlog
Require all granted
Order deny,allow
Deny from all
#Allow from fd00::/8 192.168.0.0/16 fe80::/10 127.0.0.0/8 ::1
Allow from all
ProxyPreserveHost On
ProxyPass http://127.0.0.1:4004
RequestHeader set X-Script-Name /searx
</Location>
2. Configure reverse proxy for :ref:`morty <searx morty>`, listening on
*localhost 3000*
.. code:: apache
ProxyPreserveHost On
<Location /morty >
# SetEnvIf Request_URI "/morty" dontlog
# CustomLog /dev/null combined env=dontlog
Require all granted
Order deny,allow
Deny from all
#Allow from fd00::/8 192.168.0.0/16 fe80::/10 127.0.0.0/8 ::1
Allow from all
ProxyPass http://127.0.0.1:3000
RequestHeader set X-Script-Name /morty
</Location>
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
uWSGI support
=============
Be warned, with this setup, your instance isn't :ref:`protected <searx
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 <searx 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
searx account (see :ref:`create searx 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.

.. _restart apache:
Restart service
===============
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: sh
sudo -H systemctl restart apache2
sudo -H service uwsgi restart searx
.. group-tab:: Arch Linux
.. code:: sh
sudo -H systemctl restart httpd
sudo -H systemctl restart uwsgi@searx
.. group-tab:: Fedora / RHEL
.. code:: sh
sudo -H systemctl restart httpd
sudo -H touch /etc/uwsgi.d/searx.ini
disable logs
============
For better privacy you can disable Apache logs. In the examples above activate
one of the lines and `restart apache`_::
# SetEnvIf Request_URI "/searx" dontlog
# CustomLog /dev/null combined env=dontlog
The ``CustomLog`` directive disable logs for the whole (virtual) server, use it
when the URL of the service does not have a path component (``/searx``) / is
located at root (``/``).
.. _The Debian Layout:
The Debian Layout
=================
Be aware that the Debian layout is quite different from the standard Apache
configuration. For details look at the README.Debian_
(``/usr/share/doc/apache2/README.Debian.gz``). Some commands you should know on
Debian:
* :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
