Wikisource is a VPS project for Wikisource-related tools. At the moment, it hosts only the #Wikisource Export tool (see below).

We have two VPS instances and two Toolforge tools (one each for prod and test). The latter exist because wsexport used to be hosted there, and the VPSs still use those tools' databases and email addresses.

Creating a new instance

Create a new m1.large instance running on Debian Buster (or m1.small for staging instances). Once the instance has been spawned, SSH in and follow these steps:

  1. Install PHP and Apache, along with some dependencies:
    sudo apt update && sudo apt -y upgrade
    sudo apt -y install php php-common
    sudo apt -y install php-cli php-fpm php-json php-xml php-mysql php-sqlite3 php-intl php-zip php-mbstring php-curl
    sudo apt -y install apache2 libapache2-mod-php zip unzip default-mysql-client libgl1
  2. Install Calibre by following these instructions (they recommend not to use the packaged version because it can be out of date). Note that Calibre can fail to clean up its temp files in some situations, so we also add the following in /etc/cron.daily/calibre-cleanup:
    find /tmp -name '*calibre*' -user www-data -mtime +2 -exec rm -r {} \;
  3. Install composer by following these instructions, but make sure to install to the /usr/local/bin directory and with the filename composer, e.g.:
    sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
  4. Clone the repository, first removing the html directory created by Apache.
    cd /var/www && sudo rm -rf html
    sudo git clone
    cd /var/www/tool
  5. Become the root user with sudo su root
  6. Run sudo composer install --no-dev
  7. Edit the config.php file that was created in the previous step. The main things to change are the database credentials and the temporary directory location.
  8. Make sure that all the files in the repo are owned by www-data.
    sudo chown -R www-data:www-data .
  9. Create the web server configuration file at /etc/apache2/sites-available/wsexport.conf with the following:
    <VirtualHost *:80>
            DocumentRoot /var/www/tool/public
            php_value memory_limit 512M
            # Requests with these user agents are denied.

            ErrorLog ${APACHE_LOG_DIR}/error.log
            ScriptAlias /tool "/var/www/tool/public"
            <Directory /var/www/tool/public/>

            RewriteCond %{HTTP:X-Forwarded-Proto} !https
            RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R=301,L]
  10. Enable the mod-rewrite Apache module, and enable the web server configuration.
    sudo a2dismod mpm_event
    sudo a2enmod php7.3
    sudo a2enmod rewrite
    sudo a2ensite wsexport
    sudo service apache2 reload
  11. (Re)start Apache:
    sudo service apache2 restart
    Moving forward, you should use sudo service apache2 graceful to restart the server.
  12. Set up annual log dump files by running the following weekly (it's located at /usr/local/bin/, and note that you have to put the tool's DB credentials into /etc/mysql/conf.d/wsexport.cnf):
    if [ -z "$YEAR" ]; then
      YEAR=$( date +%Y )
    echo "Dumping logs of $YEAR to $LOGDIR"
    mysqldump --defaults-file=/etc/mysql/conf.d/wsexport.cnf \
            --host=tools.db.svc.eqiad.wmflabs \
            s52561__wsexport_p books_generated \
            --where="YEAR(time) = $YEAR" \
            | gzip -c > $LOGDIR/$YEAR.sql.gz
    ls -l $LOGDIR
