All commands must be done as root or sudo user. Useful links: https://www.digitalocean.com/community/tutorials/how-to-deploy-a-flask-application-on-an-ubuntu-vps http://flask.pocoo.org/docs/0.11/deploying/mod_wsgi/

1. First of all, it is recommended to upgrade your Ubuntu to actual state: apt-get update apt-get upgrade

2. Installing Apache, mod_wsgi, python3-dev and other dependencies apt-get install apache2 apt-get install libapache2-mod-wsgi-py3 python3-dev apt-get install wkhtmltopdf

3. Creating site structure (assuming we are in a home directory now and archive file with site's files is here too) mkdir /var/www/web_langdetect unzip -a <archive.zip> (if your distribution does not contain unzip, install it with "apt-get install unzip" as usually) cp -R app /var/www/web_langdetect cp app.wsgi /var/www/web_langdetect cp web_langdetect.conf /etc/apache2/sites-available

4. Creating virtual environment apt-get install python3-pip pip3 install virtualenv cd /var/www virtualenv --no-site-packages web_langdetect

4.1 Installing packages to virtual environment cd /var/www mkdir nltk_data cd web_langdetect source bin/activate pip3 install flask pip3 install langdetect pip3 install nltk pip3 install lxml pip3 install pdfkit

python3 (this will open python interpreter, write the following commands there) import nltk nltk.download() This will open nltk download menu, which can be either with graphical interface or in console. First of all, you must check that nltk data directory is set to /var/www/nltk_data, if not, set it. Then download package named "punkt" and exit from interpreter with Ctrl-C or exit() call.

5. Configuring Apache. We have already copied web_langdetect.conf to apache sites directory on step 3. If you have domain name, open that file (nano /etc/apache2/sites-available/web_langdetect.conf) and replace mywebsite.com with name needed. Then: a2ensite web_langdetect a2dissite 000_default service apache2 restart

6. Open a browser and go to http://localhost, you should see main page

7. Upload directory permissions cd /var/www/web_langdetect/app chown -R www-data upload chmow 744 upload

8. That is all, now files uploading should work. If anything goes wrong, call: cat /var/log/apache2/error.log to see latest error messages from Apache
