Description

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

Wikisource Export

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 php-imagick
    sudo apt -y install apache2 libapache2-mod-php libapache2-mod-perl2 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 Install Calibre by following these instructions (they recommend not to use the packaged version because it can be out of date).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:
    #!/bin/bash
    
    find /tmp -path '*calibre*tmp*' -user www-data -mtime +1 -exec rm -r {} \;
    
  3. Install some fonts. Mostly these are available in the Debian repositories, but the Mukta family must be installed manually to maintain backwards compatibility (these used to be packaged with the tool's code).
    sudo apt -y install fonts-freefont-ttf fonts-linuxlibertine fonts-dejavu-core fonts-gubbi
    wget https://fonts.google.com/download?family=Mukta -O Mukta.zip
    wget https://fonts.google.com/download?family=Mukta%20Mahee -O MuktaMahee.zip
    wget https://fonts.google.com/download?family=Mukta%20Malar -O MuktaMalar.zip
    wget https://fonts.google.com/download?family=Mukta%20Vaani -O MuktaVaani.zip
    sudo unzip Mukta.zip -d /usr/local/share/fonts/Mukta
    sudo unzip MuktaMahee.zip -d /usr/local/share/fonts/MuktaMahee
    sudo unzip MuktaMalar.zip -d /usr/local/share/fonts/MuktaMalar
    sudo unzip MuktaVaani.zip -d /usr/local/share/fonts/MuktaVaani
    sudo fc-cache -v
    
  4. 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
    
  5. Clone the repository, first removing the html directory created by Apache.
    cd /var/www && sudo rm -rf html
    sudo git clone https://github.com/wsexport/tool.git
    cd /var/www/tool
    
  6. Become the root user with sudo su root
  7. Run sudo composer install --no-dev
  8. 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.
  9. Make sure that all the files in the repo are owned by www-data.
    sudo chown -R www-data:www-data .
    
  10. Create the web server configuration file at /etc/apache2/sites-available/wsexport.conf with the following:
    <VirtualHost *:80>
            ServerName wsexport.wmflabs.org
            Redirect / https://ws-export.wmcloud.org/
    </VirtualHost>
    <VirtualHost *:80>
            DocumentRoot /var/www/tool/public
            ServerName wsexport.wmcloud.org
            
            php_value memory_limit 512M

    </VirtualHost>
    
  11. Set PHP configuration in /etc/php/7.3/mods-available/wsexport.ini:
    max_execution_time = 60;
    
    And enable it with sudo phpenmod wsexport
  12. 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
    
  13. (Re)start Apache:
    sudo service apache2 restart
    
    Moving forward, you should use sudo service apache2 graceful to restart the server.
  14. Install AWStats:
    1. Download from https://www.awstats.org/ and extract to /var/www/awstats/ (so it contains wwwroot/, tools/, etc.)
    2. Make sure the web server user can read logs at /var/log/apache2/access.log* (set create 644 root adm in /etc/logrotate.d/apache2)
    3. Set the following in /var/www/awstats/wwwroot/cgi-bin/awstats.ws-export.wmcloud.org.conf:
      	LogFile="/var/www/awstats/tools/logresolvemerge.pl /var/log/apache2/access.log* |"
      	LogFormat="%host %time1 %methodurl %code %refererquot %uaquot
      	SiteDomain="ws-export.wmcloud.org"
      	DirCgi="/awstats/cgi-bin"
      	DirIcons="/awstats/icon"
    4. Set up the cronjob to compile the stats daily:
      @daily perl /var/www/awstats/wwwroot/cgi-bin/awstats.pl -config=ws-export.wmcloud.org
  15. Set up annual log dump files by running the following weekly (it's located at /usr/local/bin/wsexport-dump-logs.sh, and note that you have to put the tool's DB credentials into /etc/mysql/conf.d/wsexport.cnf):
    #!/bin/bash
    YEAR="$1"
    if [ -z "$YEAR" ]; then
      YEAR=$( date +%Y )
    fi
    LOGDIR=/var/www/tool/public/logs
    echo "Dumping logs of $YEAR to $LOGDIR"
    mysqldump --defaults-file=/etc/mysql/conf.d/wsexport.cnf \
            --host=tools.db.svc.eqiad1.wikimedia.cloud \
            s52561__wsexport_p books_generated \
            --where="YEAR(time) = $YEAR" \
            | gzip -c > $LOGDIR/$YEAR.sql.gz
    ls -l $LOGDIR
