</aside>
|
||
<p>SearXNG is a <em>rolling release</em>; 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:</p>
|
||
<ul class="simple">
|
||
<li><p>Bot protection has been switched from filtron to SearXNG’s <a class="reference internal" href="searx.limiter.html#limiter"><span class="std std-ref">limiter</span></a>, this requires a <a class="reference internal" href="settings/settings_redis.html#settings-redis"><span class="std std-ref">Redis</span></a> database.</p></li>
|
||
<li><p>The image proxy morty is no longer needed, it has been replaced by the
|
||
<a class="reference internal" href="settings/settings_server.html#image-proxy"><span class="std std-ref">image proxy</span></a> from SearXNG.</p></li>
|
||
<li><p>To save bandwidth <a class="reference internal" href="settings/settings_ui.html#static-use-hash"><span class="std std-ref">cache busting</span></a> has been implemented.
|
||
To get in use, the <code class="docutils literal notranslate"><span class="pre">static-expires</span></code> needs to be set in the <a class="reference internal" href="installation-uwsgi.html#uwsgi-setup"><span class="std std-ref">uWSGI setup</span></a>.</p></li>
|
||
</ul>
|
||
<p>To stay tuned and get in use of the new features, instance maintainers have to
|
||
update the SearXNG code regularly (see <a class="reference internal" href="#update-searxng"><span class="std std-ref">How to update</span></a>). 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.</p>
|
||
<div class="admonition hint">
|
||
<p class="admonition-title">Hint</p>
|
||
<p>First of all: SearXNG is installed by the script <a class="reference internal" href="../utils/searxng.sh.html#searxng-sh"><span class="std std-ref">utils/searxng.sh</span></a>. If you
|
||
have old filtron, morty or searx setup you should consider complete
|
||
uninstall/reinstall.</p>
|
||
</div>
|
||
<p>Here you will find a list of changes that affect the infrastructure. Please
|
||
check to what extent it is necessary to update your installations:</p>

|
||
<p>If your searx instance was installed <em>“Step by step”</em> or by the <em>“Installation
|
||
scripts”</em>, 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:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/filtron.sh remove all
|
||
$ sudo -H ./utils/morty.sh remove all
|
||
$ sudo -H ./utils/searx.sh remove all
|
||
</pre></div>
|
||
</div>
|
||
<div class="admonition hint">
|
||
<p class="admonition-title">Hint</p>
|
||
<p>If you are migrate from searx take into account that the <code class="docutils literal notranslate"><span class="pre">.config.sh</span></code> is no
|
||
longer used.</p>
|
||
</div>
|
||
<p>If you upgrade from searx or from before <a class="extlink-pull reference external" href="https://github.com/searxng/searxng/pull/1332">PR 1332</a> has been merged and you
|
||
have filtron and/or morty installed, don’t forget to remove HTTP sites.</p>
|
||
<p>Apache:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/filtron.sh apache remove
|
||
$ sudo -H ./utils/morty.sh apache remove
|
||
</pre></div>
|
||
</div>
|
||
<p>nginx:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/filtron.sh nginx remove
|
||
$ sudo -H ./utils/morty.sh nginx remove

|
||
<p>Once you have done your installation, you can run a SearXNG <em>check</em> procedure,
|

to see if there are some left overs. In this example there exists a <em>old</em>
