Sogoresearch-Server-Config

First of all, connect to the VM using SSH:

$ ssh user@ip_address (ex: ssh nick@12.34.56.789)

Then, update the server:

$ sudo apt-get update
$ sudo apt-get upgrade

Installing Python 3.6 and Pip3

sudo apt install python3-pip

Installing Apache and WSGI

First, to install Apache you'll need to run:

$ sudo apt-get install apache2

After that, we need to get WSGI, so run the following:

$ sudo apt-get install libapache2-mod-wsgi-py3

Once we have that, we need to make sure we've enabled WSGI with the following:

$ sudo a2enmod wsgi

Configure WSGI

Creating emojiset_app.conf

So now we need to set up our Flask configuration file:

$ cd /etc/apache2/sites-available/
$ sudo nano emojiset_app.conf

This is where your Flask configuration goes, which will apply to your live web site. Here's the code that you need to include:

<VirtualHost *:80>
                ServerName yourdomain.com(yours system ipaddress)
                ServerAdmin youemail@email.com
                WSGIScriptAlias / /var/www/html/flaskapp.wsgi
                WSGIApplicationGroup %{GLOBAL}
                WSGIProcessGroup %{GLOBAL}
                WSGIDaemonProcess emojiset_app processes=2 threads=6
                <Directory /var/www/html/EmojisetWebsite/emojiset_app/ >
                        Order allow,deny
                        Allow from all
                </Directory>
                Alias /static /var/www/html/EmojisetWebsite/emojiset_app/static
                <Directory /var/www/FlaskApp/FlaskApp/static/>
                        Order allow,deny
                        Allow from all
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                LogLevel warn
                CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

For your notes, if you want to add more domains/subdomains that point to the same Flask App, or a different app entirely, you can use a ServerAlias, added underneath the ServerAdmin line. We are now ready to enable the server. Run:

$ sudo a2ensite FlaskApp
$ service apache2 reload

Move to the directory where our application will be located:

$ cd /var/www/html/

Creating flaskapp.wsgi

Create a wsgi config file

$ sudo nano flaskapp.wsgi

Within the wsgi file, enter:

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/EmojisetWebsite")

from emojiset_app import app as application
application.secret_key = 'fhkjdskjgf(anything)’

Get code from GitHub

Clone code from GitHub:

$ sudo git clone https://github.com/username/RepositoryName.git

The application is now located in /var/www/html/EmojisetWebsite

Install Python Libraries

There is a requirements.txt file in /var/www/html/EmojisetWebsite

$ cd /var/www/html/EmojisetWebsite
$ sudo apt-get install libtool
$ sudo apt-get install autoconf
$ sudo apt-get install bison flex
$ sudo pip3 install -r requirements.txt

Install Redis Server

$ sudo apt-get install redis-server
$ redis-server --daemonize yes

Create Redis Queue Workers using Screen

$ sudo apt-get install screen

Create a new screen for each worker. You will need workers for small dataset page and for large dataset page.

$ screen -S screen_name
$ cd /var/www/html/EmojisetWebsite

Adding a new worker for small dataset:

$ rq worker small

Adding a new worker for large dataset:

$ rq worker long

Giving application folder Read/Write access

$ cd /var/www/html/
$ sudo chmod -R a+rwx /EmojisetWebsite

Restart Apache:

$ sudo service apache2 restart
