# Manual installation instructions
|
|
|
|
These intructions are inspired from a standard django/gunicorn/postgresql instructions ([for example](https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04))
|
|
|
|
!!! warning
|
|
Be sure to use pyton3.9 and pip related to python 3.9. Depending on your distribution calling `python` or `pip` will use python2 instead of pyton 3.9.
|
|
|
|
## Prerequisites
|
|
|
|
*Optional*: create a virtual env and activate it
|
|
|
|
Get the last version from the repository: `git clone https://github.com/vabene1111/recipes.git -b master`
|
|
|
|
Install postgresql requirements: `sudo apt install libpq-dev postgresql`
|
|
Install project requirements: `pip3.9 install -r requirements.txt`
|
|
|
|
## Setup postgresql
|
|
|
|
Run `sudo -u postgres psql`
|
|
|
|
In the psql console:
|
|
|
|
```sql
|
|
CREATE DATABASE djangodb;
|
|
CREATE USER djangouser WITH PASSWORD 'password';
|
|
GRANT ALL PRIVILEGES ON DATABASE djangodb TO djangouser;
|
|
ALTER DATABASE djangodb OWNER TO djangouser;
|
|
|
|
--Maybe not necessary, but should be faster:
|
|
ALTER ROLE djangouser SET client_encoding TO 'utf8';
|
|
ALTER ROLE djangouser SET default_transaction_isolation TO 'read committed';
|
|
ALTER ROLE djangouser SET timezone TO 'UTC';
|
|
|
|
--Grant superuser right to your new user, it will be removed later
|
|
ALTER USER djangouser WITH SUPERUSER;
|
|
```
|
|
|
|
Download the `.env` configuration file and **edit it accordingly**.
|
|
```shell
|
|
wget https://raw.githubusercontent.com/vabene1111/recipes/develop/.env.template -O .env
|
|
```
|
|
|
|
## Initialize the application
|
|
|
|
Execute `export $(cat .env |grep "^[^#]" | xargs)` to load variables from `.env`
|
|
|
|
Execute `/python3.9 manage.py migrate`
|
|
|
|
and revert superuser from postgres: `sudo -u postgres psql` and `ALTER USER djangouser WITH NOSUPERUSER;`
|
|
|
|
Generate static files: `python3.9 manage.py collectstatic` and remember the folder where files have been copied.
|
|
|
|
## Setup web services
|
|
|
|
### gunicorn
|
|
|
|
Create a service that will start gunicorn at boot: `sudo nano /etc/systemd/system/gunicorn_recipes.service`
|
|
|
|
And enter these lines:
|
|
|
|
```service
|
|
[Unit]
|
|
Description=gunicorn daemon for recipes
|
|
After=network.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
Restart=always
|
|
RestartSec=3
|
|
Group=www-data
|
|
WorkingDirectory=/media/data/recipes
|
|
EnvironmentFile=/media/data/recipes/.env
|
|
ExecStart=/opt/.pyenv/versions/3.9/bin/gunicorn --error-logfile /tmp/gunicorn_err.log --log-level debug --capture-output --bind unix:/media/data/recipes/recipes.sock recipes.wsgi:application
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
*Note*: `-error-logfile /tmp/gunicorn_err.log --log-level debug --capture-output` are usefull for debugging and can be removed later
|
|
|
|
*Note2*: Fix the path in the `ExecStart` line to where you gunicorn and recipes are
|
|
|
|
Finally, run `sudo systemctl enable gunicorn_recipes.service` and `sudo systemctl start gunicorn_recipes.service`. You can check that the service is correctly started with `systemctl status gunicorn_recipes.service`
|
|
|
|
### nginx
|
|
|
|
Now we tell nginx to listen to a new port and forward that to gunicorn. `sudo nano /etc/nginx/sites-available/recipes.conf`
|
|
|
|
And enter these lines:
|
|
|
|
```nginx
|
|
server {
|
|
listen 8002;
|
|
#access_log /var/log/nginx/access.log;
|
|
#error_log /var/log/nginx/error.log;
|
|
|
|
# serve media files
|
|
location /static {
|
|
alias /media/data/recipes/staticfiles;
|
|
}
|
|
|
|
location /media {
|
|
alias /media/data/recipes/mediafiles;
|
|
}
|
|
|
|
location / {
|
|
proxy_pass http://unix:/media/data/recipes/recipes.sock;
|
|
}
|
|
}
|
|
```
|
|
|
|
*Note*: Enter the correct path in static and proxy_pass lines.
|
|
|
|
Enable the website `sudo ln -s /etc/nginx/sites-available/recipes.conf /etc/nginx/sites-enabled` and restart nginx : `sudo systemctl restart nginx.service`
