Setup for production

Getting things setup for production take a little bit of effort but here are all the steps that are required for a Linux host.

Get the code

Copy to home directory as rendezvous

git clone https://github.com/corytodd/rendezvous.git

We can't do anything else until we get the server and service handlers setup so let us proceed.

Database prep

We don't keep the db in the code repo so securely copy the database to the server

scp -i .ssh\<my_key> rendezvous.sqlite3 <name>@<host>:/home/<name>/rendezvous

If you'd like, you can install sqlite3 from your package manager and poke around in the database. There is nothing sensitive in there so have fun.

Server prep

This assumes you have a function server stack using nginx. Create file named after your host, e.g. tiger.corytodd.us.conf in /etc/nginx/sites-available

server {
    listen 80;
    server_name     example.com;
    location / {
            try_files       $uri    @app;
    }

    location @app {
            include         uwsgi_params;
            uwsgi_pass      unix:/home/user/rendezvous/rendezvous.sock;
    }

    location ~ /\. {
            deny all;
    }
}
server {
    listen 443;
    server_name     example.com;
    location / {
            try_files       $uri    @app;
    }

    location @app {
            include         uwsgi_params;
            uwsgi_pass      unix:/home/user/rendezvous/rendezvous.sock;
    }

    location ~ /\. {
            deny all;
    }
}

Then test for typos

sudo nginx -t

If no problems, restart the server

sudo service nginx restart

Setup Python 3.6 (and other stuff we'll need)

We need Python 3.6 so add the ppa that has this pre-build for us

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update

We need a bunch of stuff for the uwsgi plugin so let's just do it all at once

sudo apt-get install build-essential python3.6 python3.6-dev uwsgi uwsgi-src uuid-dev libcap-dev libpcre3-dev libssl-dev
python36 -m venv ~/rendezvous/venv
source ~/rendezvous/venv
pip install -r requirements.txt
python -m textblob.download_corpora

cd ~
PYTHON=python3.6 uwsgi --build-plugin "/usr/src/uwsgi/plugins/python python36"
sudo mv python36_plugin.so /usr/lib/uwsgi/plugins/python36_plugin.so
sudo chmod 644 /usr/lib/uwsgi/plugins/python36_plugin.so

We should now have python36, the python36 uwsgi plugin, and a shiny venv. If so, we're ready to serve.

Serving

This is the easy part!

uwsgi config.ini

The server should now be running.
