viberMongoBot

simple viber bot built with viber python api + mongo-flask-gunicorn-nginx

(assuming Ubuntu 18.04 Env)

• install mongoDb:

 wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -
 echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo service mongod start
sudo systemctl enable mongod.service

• install ngninx:

sudo apt update
sudo apt install nginx

• install python3 components:

sudo apt update
sudo apt install python3-pip python3-dev build-essential libssl-dev libffi-dev python3-setuptools

• set up a virtual environment in order to isolate our Flask application from the other Python files on the system:

sudo apt install python3-venv
mkdir ~/netviber
cd ~/netviber
python3.6 -m venv netviberenv
source netviberenv/bin/activate
pip install wheel
pip install gunicorn flask
pip install pymongo
pip install viberbot

• then we create our flaskapp(flaskTest.py)

• allow firewall at port 5000:

sudo ufw allow 5000

• create wsgi file:

nano ~/netviber/wsgi.py

• file content:

from netviber import app

if __name__ == "__main__":
    app.run()

• Bind gunicorn on port 5000:

gunicorn --bind 0.0.0.0:5000 wsgi:app

• terminate virtual env

deactivate

• Let’s create the systemd service unit file:

sudo nano /etc/systemd/system/netviber.service

• file content:

[Unit]
Description=Gunicorn instance to serve netviber
After=network.target

[Service]
User=user1
Group=www-data
WorkingDirectory=/home/user1/netviber
Environment="PATH=/home/user1/netviber/netviberenv/bin"
ExecStart=/home/user1/netviber/netviberenv/bin/gunicorn --workers 3 --bind unix:netviber.sock -m 007 wsgi:app

[Install]
WantedBy=multi-user.target

• start and enable service

sudo systemctl start netviber
sudo systemctl enable netviber

• NGINX:

sudo nano /etc/nginx/sites-available/netviber

• Nginx sites-available content:

server {
    listen 80;
    server_name your.server.name

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/user1/netviber/netviber.sock;
    }
}

sudo ln -s /etc/nginx/sites-available/netviber /etc/nginx/sites-enabled

• check NGINX conf:

sudo nginx -t

• Restart nginx:

sudo systemctl restart nginx

• We no longer need access through port 5000, so we can remove that rule

sudo ufw delete allow 5000

• Allow full access to the Nginx server:

sudo ufw allow 'Nginx Full'

• Let's add SSL:

sudo add-apt-repository ppa:certbot/certbot
sudo apt install python-certbot-nginx
sudo certbot --nginx -d your_domain -d www.your_domain

• We no longer need the redundant HTTP NGINX profile allowance

sudo ufw delete allow 'Nginx HTTP'

• Visit https://your_domain
