#Deployment:
- you have put every depedencies in requirements.txt
- init .gitignore to skip *.pyc and some lib files
- Install gunicorn
- Install nginx
- Configure to add gunicorn like a unit service in systemd:
create a file in
/etc/systemd/system/gunicorn.servicewith content like this:
[Unit]
Description=gunicorn daemon
After=network.target
[Service]
User=huy.nv.ngo
Group=www-data
WorkingDirectory=/home/huy.nv.ngo/BookReview
ExecStart=/home/huy.nv.ngo/BookReview/bin/gunicorn --access-logfile /var/log/belt_reviewer/gunicorn-access.log --error-logfile /var/log/belt_reviewer/gunicorn-error.log --workers 3 --bind unix:/home/huy.nv.ngo/BookReview/belt_reviewer.sock belt_reviewer.wsgi:application
[Install]
WantedBy=multi-user.target
after that , first we have to use systemctl to reload all daemon
sudo systemctl daemon-reload
after we reload, start gunicorn daemon
sudo systemctl start gunicorn
after we start this daemon => enable it
sudo systemctl enable gunicorn
Tips: if we want to specific log for it use --access-logfile parameter and --error-logfile parameter
Please chmod for the log path before start gunicorn
So if you change any thing in service script => call reload daemon
So if you want to change source code in django => restart gunicorn to update this source code
6 Configure for nginx
create a new site_avaiable:
vim /etc/nginx/sites-available/belt_reviewer
server {
listen 8000;
server_name 0.0.0.0;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/huy.nv.ngo/BookReview;
}
location / {
include proxy_params;
proxy_pass http://unix:/home/huy.nv.ngo/BookReview/belt_reviewer.sock;
}
}
after that
sudo ln -s /etc/nginx/sites-available/{{projectName}} /etc/nginx/sites-enabled
sudo nginx -t
sudo rm /etc/nginx/sites-enabled/default
sudo service nginx restart
