overview

Zango Project is basically our main project on which we can create, develop and host multiple apps under the same Infrastructure. Zango uses django-tenants package to isolate applications at the database level.

Think of it as your own private app ecosystem, where each application maintains its isolation while benefiting from shared resources and infrastructure

Pre-requisites

There are a few requisites that needs to be completed before you start creating a zango project. If you already have them configured, consider moving on to the next steps.

1. PostgreSQL Database Setup

Manual

To get started, follow these steps to set up a PostgreSQL database:

1. Install PostgreSQL: If you haven't already, you'll need to install PostgreSQL on your system. You can download the PostgreSQL installer for your platform from the official website: PostgreSQL Downloads
2. Create a Fresh Database: Once PostgreSQL is installed, open your terminal or a PostgreSQL client. Use the following command to create a new database. Replace your_database_name with the desired name for your project's database:

createdb your_database_name

Ensure that the newly created database is fresh without any existing tables or data. With the PostgreSQL database set up and ready to go, you can proceed with setting up your Zango project, confident that you have the necessary infrastructure in place.

note

Keep in mind that the exact steps for installing PostgreSQL may vary depending on your operating system. Be sure to consult the PostgreSQL documentation or installation guide for your specific platform if you encounter any issues during the installation process.

Docker

Installing and setting up postgresql database manually can be overwhelming sometimes, if you have docker installed, you can set it up in just 3 commands as follows:

1. Pull the Postgres Docker Image The first step is to pull the Postgres Docker image from the Docker Hub repository. This is done by running the following command:

   docker pull postgres

2. Create a Docker Volume Next, we need to create a Docker volume to persist our Postgres data. This is done by running the following command:

   docker volume create postgres_data

3. Run the Postgres Docker Container Now we can run the Postgres Docker container using the following command:

   docker run --name postgres_container -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 -v postgres_data:/var/lib/postgresql/data postgres

After the setup is complete, the values of DB configuration for .env would look something like:

POSTGRES_DB=postgres
POSTGRES_USER=postgres
POSTGRES_PASSWORD=mysecretpassword
POSTGRES_HOST=127.0.0.1
POSTGRES_PORT=5432

2. Redis setup

Redis is used as a broker by celery workers. Use the steps below to run redis on your local machine:

Manual

Ubuntu/Debian Linux

# Step 1: Update package list
sudo apt update

# Step 2: Install Redis
sudo apt install redis-server

# Step 3: Start Redis service
sudo systemctl start redis-server

# Step 4: Enable Redis to start on boot
sudo systemctl enable redis-server

# Step 5: Verify installation
redis-cli ping  # Should return "PONG"

macOS (using Homebrew)

# Step 1: Install Homebrew (if not installed)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Step 2: Install Redis
brew install redis

# Step 3: Start Redis
brew services start redis
# OR run without service
redis-server

# Step 4: Verify installation
redis-cli ping

From Source (Any Linux/Unix system)

# Step 1: Install dependencies
sudo apt install build-essential tcl  # For Ubuntu/Debian
# OR
sudo yum groupinstall "Development Tools"  # For RHEL/CentOS

# Step 2: Download Redis
wget https://download.redis.io/redis-stable.tar.gz

# Step 3: Extract the archive
tar xzf redis-stable.tar.gz

# Step 4: Enter directory
cd redis-stable

# Step 5: Compile
make

# Step 6: Install
sudo make install

# Step 7: Create directories and copy config
sudo mkdir /etc/redis
sudo cp redis.conf /etc/redis

# Step 8: Start Redis
redis-server

# Step 9: Verify installation
redis-cli ping

Docker

Simply run the below command to start redis inside a docker container on port 6379.

docker run --name "name" -d -p 6379:6379 redis

For example:

docker run --name zango_redis -d -p 6379:6379 redis
