🛠️ System Setup

This section covers the complete setup of system dependencies and software required to run the EQIPA (Evapotranspiration-based Quick Irrigation Performance Assessment) application on a fresh Ubuntu server.

Server Configuration

  • The EQIPA Tool requires a Linux-based Ubuntu server with AMD or intel processor minimum 8 cores, 5TB storage (considering future expansion of the database) and minimum 126 GB RAM for efficient performance.
  • Full admin access to the server

Prerequisite Software

Ensure the following software is installed:

  • Python 3.10
  • PostgreSQL
  • PostGIS
  • GRASS GIS
  • GDAL
  • Redis
  • Apache2
  • Virtualenv
  • Git
  • Build tools & Python development headers

Install Required System Packages

Check Ubuntu version 

lsb_release -a
Should be Ubuntu 22.04

sudo apt-get update

sudo apt-get install -y \
    git \
    gdal-bin \
    apache2 \
    postgis \
    redis-server \
    virtualenv \
    build-essential \
    python3-dev \
    libpq-dev \
    python3-venv \
    pango1.0-tools

Verify Installation

python3 --version

Install Python 3.10 

sudo apt install -y python3.10 python3.10-venv python3.10-dev

Choose the default python version 

sudo update-alternatives --config python3

  Selection    Path                Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3.8   2         auto mode
  1            /usr/bin/python3.8   2         manual mode
  2            /usr/bin/python3.10  1         manual mode

Install PostgreSQL & PostGIS

sudo apt-get install -y postgresql postgresql-postgis

Install GRASS GIS

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get install -y grass grass-dev

Configure PostgreSQL User and Database

Create a new PostgreSQL user:

sudo -u postgres createuser ipa_india

Login to PostgreSQL:

sudo -u postgres psql

Inside psql:

# Change password of postgres user*
ALTER USER postgres PASSWORD 'ipa_india';
ALTER USER ipa_india PASSWORD 'ipa_india123';

# Give more privileges to user ipa_india*
ALTER USER ipa_india WITH SUPERUSER;

# quit psql*
\q

Create the database and enable PostGIS:

# Create a new DB named "ipa_india":
createdb -U ipa_india -h localhost ipa_india

Pass: ipa_india123

psql -U ipa_india -h localhost ipa_india -c "CREATE EXTENSION postgis"
