How to deploy websites on a remote server

How to deploy your websites on your remote server?

It is a good idea to use your remote server to host your websites. Play around in my website. This blog takes a Flask app as an example.

Conponents: Flask, Nginx, Gunicorn

1. Set up a virtual environment

• Use Anaconda to set up a virtual environment
• Install dependencies

conda create -n env_name python
conda activate env_name

pip install -r requirements.txt

2. Set up Nginx and Gunicon

• Create the configuration files and set up accronding to your app.

code /etc/nginx/conf.d/flaskapp.conf
code /etc/systemd/system/flaskapp.service

3. Ensure permissions for your app folder

• It is suggested not to run your website as the root user.

sudo chown -R $USER:$USER /path/to/your/app
sudo chmod -R 755 /path/to/your/app
sudo chmod -R 666 /path/to/your/app

4. Ensure the firewall and ports

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

5. Restart Nginx and your Flask app

sudo nginx -t

sudo systemctl restart nginx

sudo systemctl daemon-reload

sudo systemctl enable your_app

sudo systemctl restart your_app

6. Check running services

sudo systemctl status your_app
sudo systemctl status nginx

Now it is done!
