sudo adduser yourftpuser
sudo usermod -d /your/path/for/the/user yourftpuser
sudo chown username: myfolder (To give permission of a folder to user)
Two more commands:
chown -R username directory
chmod -R u+rX directory
The first command makes the user own the directory. The second command gives them full read and access permissions. The r gives read permission, the X gives 'execute' permission to directories, and not files.

PAID SSL (GoDaddy etc) - Not Lets Encrypt
Create a directory & adjust rights:
mkdir /etc/nginx/ssl
sudo chmod -R 600 /etc/nginx/ssl
Generate 2 keys, 1 example.com.key & 2 for example.com.csr
openssl req -newkey rsa:2048 -nodes -keyout example.com.key -out example.com.csr
Fill in the informations or skip by pressing enter, except Common Name FQDN etc. Provide your website name i.e example.com
2 files will be generated:
1- example.com.key
2- example.com.csr
Provide content of this csr file by copying > cat example.com.csr and provide to SSL provider.
Once SSL zip file is downloaded from SSL Provider. Unzip it and rename with following:
1- randomnumber.crt to example.com.crt
2- xxxbundle.crt to intermediate.crt
Copy both the files to /etc/nginx/ssl
run command:
cat example.com.crt intermediate.crt > example.com.chained.crt
Then change sites-available/site to following:
server {
root /var/www/site;
index index.php index.html index.htm;
client_max_body_size 120M;
server_name example.com www.example.com;
location / {
try_files $uri $uri/ /index.php?$query_string;

include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = www.example.com) {
return 301 https://$host$request_uri;
}
if ($host = example.com) {
return 301 https://$host$request_uri;
}
server_name example.com www.example.com;
listen 80;
return 404; # managed by Certbot
}

Deployment on DigitalOcean Apps Platform of a docker react app
1- Create file named "Dockerfile" (Without any extension)
2- Create folder called .docker on root and create a file in it with name "prod.Dockerfile"
Copy below content in both the files
# Use an official Node.js runtime as a parent image
FROM node:14-alpine
# Set the working directory to /app
WORKDIR /build
# Copy the package.json and package-lock.json files to the container
COPY package*.json ./
# Install the dependencies
RUN npm install
# Install the dependencies
RUN npm install -g serve
# Copy the remaining application files to the container
COPY . .
# Build the application
RUN npm run build
# Set the production environment variable
ENV NODE_ENV=production
# Expose port 3000
EXPOSE 3000
# Start the application
CMD ["serve", "-s", "build"]
3- After that, create an app on app platform and choose this repo
4- Remove extra webservice instances, if any, other than Docker WebService.
5- Define a port i.e. 3000 in settings
6- Define start and build scripts in package.json i.e. react-scripts start
Voila!!!
