WikiEduDashboardTools

A set of PHP endpoints for pulling revision from the Replica databases in the Wikimedia Cloud environment

Setup on Toolforge

• Clone the git repo in the tool's home directory
• webservice start

Setup on Wikimedia Cloud VM

• Create a Debian server with the web security group
• Add DNS for an external URL (like impact-visualizer-tools.wmcloud.org)
• sudo apt install apache2 php libapache2-mod-php php-mysql
• Clone the git repo into /var/www/
• Disable the default site and add a new one (dashboard-too.conf)

<VirtualHost *:80>
    ServerName impact-visualizer-tools.wmcloud.org
    ServerAdmin [email protected]   
    DocumentRoot /var/www/impact-visualizer-tools/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

• Increase the PHP memory_limit in /etc/php/7.4/apache2/php.ini or similar location (to 4096M)
  • This ensures that queries that return very large amounts of data won't run PHP out of memory while converting query results to JSON.
• Enable the new site, and visit /index.php.
• Add Replica database credentials: copy replica.my.cnf from a Toolforge tool account into the tool's root directory.
• Test a query endpoint, like /count_revisions.php?lang=en&project=wikipedia...
