setup

note: this is a quick tutorial for centos7

make sure nginx is installed make sure to download a version of python3.x (I'm using 3.5 here)

clone the repo into /var/www/<app_name>/. Yes, put it inside <app_name>

replace every instance of <app_name> with whatever you want to call this thing

setup environment

create dir

mkdir /var/www/<app_name>/

change dir

cd /var/www/<app_name>/

create python3 virtual environment

virtualenv -p /usr/local/bin/python3.5 venv

activate venv

source venv/bin/activate

install requirements

pip install -r requirements.txt

exit venv

deactivate

create gunicorn daemon

create the daemon service file

vi /etc/systemd/system/<app_name>.service

    access_log  /var/log/nginx/<app_name>-access.log;
