How to update
|
|
=============
|
|
|
|
How to update depends on the :ref:`installation` method. If you have used the
|
|
:ref:`installation scripts`, use the ``update`` command from the :ref:`searxng.sh`
|
|
script.
|
|
|
|
.. code:: sh
|
|
|
|
sudo -H ./utils/searxng.sh instance update

How to inspect & debug
|
|
======================
|
|
|
|
How to debug depends on the :ref:`installation` method. If you have used the
|
|
:ref:`installation scripts`, use the ``inspect`` command from the :ref:`searxng.sh`
|
|
script.

|
|
|
|
SearXNG is a *rolling release*; each commit to the master branch is a release.
|
|
SearXNG is growing rapidly, the services and opportunities are change every now
|
|
and then, to name just a few:
|
|
|
|
- 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- The image proxy morty is no longer needed, it has been replaced by the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.
|
|
|
|
Here you will find a list of changes that affect the infrastructure. Please
|
|
check to what extent it is necessary to update your installations:
|
|
|
|
:pull:`1595`: ``[fix] uWSGI: increase buffer-size``
|
|
Re-install uWSGI (:ref:`searxng.sh`) or fix your uWSGI ``searxng.ini``
|
|
file manually.
|
|
|
|
|
|
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.
|
|
|
|
If you upgrade from searx or from before :pull:`1332` has been merged and you
|
|
have filtron and/or morty installed, don't forget to remove HTTP sites.
|
|
|
|
Apache::
|
|
|
|
$ sudo -H ./utils/filtron.sh apache remove
|
|
$ sudo -H ./utils/morty.sh apache remove
|
|
|
|
nginx::
|
|
|
|
$ sudo -H ./utils/filtron.sh nginx remove
|
|
$ sudo -H ./utils/morty.sh nginx remove
|
|
|
|
|
|
|
|
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
|
|
|
|
