<h1>The Expo server</h1>
|
|
<p>Troggle is the software which runs the the expo cave survey data management and website. It is not the only thing running on the expo server.
|
|
|
|
<h3 id="what">Server configuration: directory structure</a></h3>
|
|
<p>This is the folder structure of the repo <var>:expoweb:</var> which is also the root
|
|
of the website. Note that the webserver (apache) presents many more apparent folders, such as <var>expofiles</var>, than there are folders because that's what it and troggle do.
|
|
<p>In the list below only the <var>handbook</var> folder has been expanded. The <var>years</var> folder includes
|
|
42 subfolders from <var>1976</var> to <var>2022</var>.

<p>The handbook illustrates the i/t/l idiom whereby an image file (i) is displayed with a paragraph of text as an HTML file (l) and there is a thumbnail image (t) which is included in another document, e.g. see <a href="/guidebook/walkin.htm">the photographic guide to the walk from the toll road car park</a>.
|
|
|
|
<h4 id="css">CSS and HTML</a></h4>
|
|
|
|
<p>The <var>expoweb</var> repo contains all the HTML files and basic CSS files. The <var>troggle</var> repo contains the HTML templates, CSS for the troggle report pages generated dynamically and a copy of the CSS, thumbnail images and javascript for the Django admin package which has to be available under the url '/site_media/' (which resolves to expo/troggle/media/) for the admin system to work.
|
|
<p>
|
|
See the live report on which urls resolve to which actual folders at <a href="/pathsreport">pathsreport</a>.

<p><b>Now, if you don't know</b> your <em>wsgi</em> from your <em>asgi</em>, read <a href=
|
|
"https://james.walters.click/what-django-deployment-is-really-about.html">this article
|
|
</a> first on how to generically configure a Django server in the simplest possible
|
|
way.
|
|
|
|
<hr />
|
|
|
|
<p>The server configuration scripts are in the file <var>troggle/_deploy/debian-server/wookey-exposerver-recipe.txt</var> and are also
|
|
documented with notes in <var>troggle/README.txt</var>. It is intended that the full documentation will
|
|
be moved here in due course.
|
|
<p>It is hoped that we will develop fully automated server setup scripts (such as are used by CUYC for their Django system)
|
|
<ul>
|
|
<li>to create a development server running locally on a personal machine
|
|
<li>to install the master system following a new operating system install on the public server
|
|
</ul>
|
|
|
|
<p>Apache needs to run as user 'expo', not 'www-data' as standard. This is due to a basic incompatibility in permissions between apache and git: git does not honour existing permissions exactly. See
|
|
<a href="https://nim-labs.com/run-apache-alternate-user/">How to run apache as an alternate user</a>.
|
|
|
|
<p>Although troggle will appear to work with sqlite database, it needs a proper concurrrent access database to manage multiple users. sqlite is
|
|
single-user (effectively a separate instance of django is created for each page access, so even one person looking at several pages at once is
|
|
"multi-user").
|
|
<p>The folder structure on the server is as shown below. It is all
|
|
in the user folder for the user <var>expo</var> i.e. in
|
|
<br>/home/user/expo:

<h3 id="js">Javascript</a></h3>
|
|
There are javascript packages installed directly on the operating system on the server, i.e. in<br>
|
|
<code>/usr/share/javascript</code>
|
|
which are used by some <var>expoweb</var> pages:
|
|
<ul>
|
|
<li><var>CaveScript</var> for showing 3D views of cave centreline data,
|
|
<li><var>CodeMirror</var> for syntax-colouring survex files
|
|
<li><var>openlayers</var> for geographic mapping integration, for out slippy map showing paths and entrances at <a href="/map/map.html">/map/map.html</a>
|
|
<li><var>leaflets</var> and experimental mapping test (only on /map/index-leaflet.html )
|
|
</ul>
|
|
These javascript packages are not documented but some are mentioned in <a href="troglaptop.html">the soft dev laptop</a> configuration.
|
|
|
|
<p>Currently installed on the server (October 2021) are the following javascript packages which are <em>not used at all by troggle or any of the expo website</em>:
|
|
<ul>
|
|
<li>jquery
|
|
<li>jquery-ui
|
|
<li>mootools
|
|
<li>sphinxdoc
|
|
<li>underscore
|
|
</ul>
|
|
<p>Presumably these are used by something else hosted on the server ? Anyway, if you are setting up a new troggle sever you don't need them.
|
|
|
|
|
|
|
|
|
|
<h3 id="xapian">Search: xapian</h3>
|
|
<p>Installed independently of troggle simply with <var>apt install xapian-omega</var> and
|
|
then configured into the troggle-generated menus in <var>css/main2.css</var>.
|
|
You can see it at the bottom of the top-left menu on this page and on nearly all pages of the handbook.
|
|
The function is
|
|
connected with an apache configuration
|
|
<code>ScriptAlias /search /usr/lib/cgi-bin/omega/omega</code> in <var>~expo/config/apache/expo.conf</var>.
|
|
Installed by Wookey in May 2020.
|
|
|
|
<h3 id="kanboard">Planning: kanboard</h3>
|
|
<p>This is installed on the server and accessed at <a href="/kanboard"><var>/kanboard</var></a> It is an open source
|
|
equivalent of the Trello kanban card task planning system. The 2022 expo uses
|
|
<a href="https://trello.com/b/WddB62HI/expo-jobs">Trello itself</a> (separate login required) but we intend to move to our own kanboard
|
|
from 2023.
|
|
|
|
<h3 id="boe">boe</h3>
|
|
<p>This is a perl script, and served by the webserver using the url apache configuration<pre><code>#bank of expo
|
|
#current expedition
|
|
ScriptAlias /boe /home/expo/boe/boc/boc.pl
|
|
<Directory /home/expo/boe/boc>
|
|
AddHandler cgi-script .pl
|
|
SetHandler cgi-script
|
|
Options +ExecCGI
|
|
Require all granted
|
|
</Directory></code></pre> in <var>~expo/config/apache/expo.conf</var>.
|
|
<p>Handbook documentation for its use is at <a href="../bankofexpo.html">The Bank of Expo</a>.
|
|
|
|
<h3 id="cgit">cgit - web interface to server git repos</h3>
|
|
<p>This is a compiled executable written in C which, like boe, is installed as an Apache CGI redirection.
|
|
The installation instructions are at <a href="https://git.zx2c4.com/cgit/tree/README">https://git.zx2c4.com/cgit/tree/README</a>
|
|
but we use the Debian package <a href="https://packages.debian.org/stable/cgit">https://packages.debian.org/stable/cgit</a>.
|
|
|
|
<h3>cron - automatically run tasks to schedule</h3>
|
|
<p>This is currently disabled in Feb. 2022. If you need anything that would be done frequently (e.g. bins) you currently have to run it manually.
|
|
<p>The server runs it's hourly, daily and weekly scripts using the anacron system. In
|
|
<var>~expo/config/cron/</var> on the server, there are <var>expo.hourly</var>
|
|
and <var>expo.daily</var> scripts and these are (or should be) launched at the appropriate times by
|
|
the server root from <var>/etc/crontab</var>. This is not obviously working on the server at present.
|
|
|
|
<h3 id="runserver">Running a test Troggle server</h3>
|
|
<p>
|
|
For high volume use, Troggle should be run using a web server like apache.
|
|
However, a quick way to get started is to use the development server built into Django.
|
|
This is limited though: directory redirection needs apache so CodeMirror and CaveView won't work as the url /javascript/ will not exist.
|
|
<p>
|
|
To do this, run
|
|
<code>
|
|
$ python manage.py runserver 8000 -v 3
|
|
</code>
|
|
from the troggle directory. This runs it on port 8000 so you see the website
|
|
at http://localhost:8000/
|
|
<p>
|
|
gunicorn also works. This runs with 9 workers (suitable for a 4-core processor,
|
|
-w takes n+1 where n is the number of cores of your processor):
|
