In this tutorial, we will show you how to install and configure Elgg social networking platform on Ubuntu 20.04.

Prerequisites

• A fresh Ubuntu 20.04 VPS on the Atlantic.net Cloud Platform
• A valid domain name pointed to your server IP
• A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Ubuntu 20.04 as the operating system with at least 2GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your Ubuntu 20.04 server, run the following command to update your base system with the latest available packages.

apt-get update -y

Step 2 – Install Apache, MariaDB and PHP

Elgg runs on Apache web server, is written in PHP, and uses MySQL/MariaDB as a database backend, so you will need to install the Apache, MariaDB, PHP and other required PHP extensions to your server. You can install all of them with the following command:

apt-get install apache2 mariadb-server php libapache2-mod-php php-common php-sqlite3 php-curl 
php-intl php-mbstring php-xmlrpc php-mysql php-gd php-xml php-cli php-zip unzip wget -y

After installing all the packages, edit the php.ini file and change some recommended settings.

nano /etc/php/7.4/apache2/php.ini

Change the following values:

max_execution_time = 300
memory_limit = 512M
upload_max_filesize = 100M
date.timezone = Asia/Kolkata

Save and close the file, then restart the Apache service to apply the configuration changes.

systemctl restart apache2

Step 3 – Create a Database for Elgg

Next, you will need to create a database and user for Elgg. First, log in to MySQL shell with the following command:

mysql

Once logged in, create a database and user with the following command:

CREATE DATABASE elgg;
CREATE USER 'elgg'@'localhost' IDENTIFIED BY 'secure-password';

Next, grant all the privileges to the elgg database with the following command:

GRANT ALL ON elgg.* TO 'elgg'@'localhost' IDENTIFIED BY 'secure-password' WITH GRANT 
OPTION;

Next, flush the privileges and exit from the MariaDB shell with the following command:

FLUSH PRIVILEGES;
EXIT;

At this point, the MariaDB database is created for Elgg.

Step 4 – Install Elgg

First, download the latest version of Elgg from its official website using the following command:

wget https://elgg.org/download/elgg-3.3.13.zip

Once the download is completed, unzip the downloaded file with the following command:

unzip elgg-3.3.13.zip

Next, move the extracted directory to the Apache root directory:

mv elgg-3.3.13 /var/www/html/elgg

Next, create a data directory and set proper ownership and permissions to the Elgg directory:

mkdir /var/www/html/data
chown -R www-data:www-data /var/www/html/elgg
chown -R www-data:www-data /var/www/html/data
chmod -R 755 /var/www/html/elgg

Once you are finished, you can proceed to the next step.

Step 5 – Configure Apache for Elgg

Next, you will need to configure Apache to serve Elgg. You can configure it by creating a new Apache virtual host configuration file:

nano /etc/apache2/sites-available/elgg.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/elgg/
ServerName elgg.example.com
Options FollowSymLinks
AllowOverride All
ErrorLog /var/log/apache2/elgg-error_log
CustomLog /var/log/apache2/elgg-access_log common
</VirtualHost>

Save and close the file, then enable the virtual host and Apache rewrite module with the following command:

a2ensite elgg.conf
a2enmod rewrite

Finally, restart the Apache service to apply the changes:

systemctl restart apache2

Step 6 – Access Elgg Web Interface

Now, open your web browser and access the Elgg web interface using the URL http://elgg.example.com. You should see the Elgg welcome screen:

Cycles enumeration (aka Bubbles) as part of de novo de bruijn graphs assembly using colours can be unpractical for large error prone genomes which makes the assembly process produce an excessive number of false positive cycles.  Our solution is to search the graph in multicores shared memory parallel mode using graph decomposition then use filtering method to generate good quality SNPs.

Relying on unique software architecture, PLAST takes full advantage of recent multi-core personal computers without requiring any additional hardware devices.

PLAST stands for Parallel Local Sequence Alignment Search Tool and is was published in BMC Bioinformatics.

PLAST is a general purpose sequence comparison tool providing the following benefits:

• PLAST is a high-performance sequence comparison tool designed to compare two sets of sequences (query vs. reference),
• Reduces the processing time of sequences comparisons while providing highest quality results,
• Contains a fully integrated data filtering engine capable of selecting relevant hits with user-defined criteria (E-Value, identity, coverage, alignment length, etc.),
• Does not require any additional hardware, since it is a software solution. It is easy to install, cost-effective, takes full advantage of multi-core processors and uses a small RAM footprint,
• Ready to be used on desktop computer, cluster, cloud as well as within distributed system running Hadoop.

This is the demo application of the Carrot² clustering engine. It uses Carrot²'s algorithms to organize search results into thematic folders.

User interfaces

• Web Search Clustering organizes search results from public search engines into clusters; offers treemap- and pie-chart visualizations of the clusters.
• Clustering Workbench clusters content from local files in JSON or Excel format, Solr or Elasticsearch; allows tuning of clustering parameters and exporting results as Excel or JSON.

Search engines

• Web: web search results provided by etools.ch. Extensive use may require special arrangements with the owner of the etools.ch service.
• PubMed: abstracts of medical papers from the PubMed database provided by NCBI.
• Local file: content read from a local file in Carrot2 XML, JSON, CSV or Excel format.
• Solr: queries an Apache Solr instance.
• Elasticsearch: queries an Elasticsearch instance.

Clustering algorithms

• Lingo: creates well-described flat clusters. Does not scale beyond a few thousand search results. Available as part of the open source Carrot² framework.
• STC: the classic search results clustering algorithm. Produces flat cluster with adequate description, very fast. Available as part of the open source Carrot² framework
• k-means: base line clustering algorithm, produces bag-of-words style cluster descriptions. Available as part of the open source Carrot² framework
