Hardware Requirements

  • 4 CPU Core
  • 4GB RAM

Server Settings

Update and Upgrade Packages

sudo apt-get upgrade -y

Create a new user 

sudo adduser [frappe-user]
usermod -aG sudo [frappe-user]
su [frappe-user] 
cd /home/[frappe-user]

Ensure you have replaced [frappe-user] with your username. eg. sudo adduser frappe

Install Required Packages

For setting up ERPNext, an application that runs on the Frappe Framework, we need to install several software packages first. These packages help ensure that ERPNext functions correctly on your system.

Install Python

ERPNext version 15 requires Python version 3.10+. This is what we will install in this step.

Adding PPA repository

Add the deadsnakes PPA repository to the system next. The simplest method for installing Python 3.11 is as follows:

sudo add-apt-repository ppa:deadsnakes/ppa

Use this command to install Python 3.11 on Ubuntu 22.04:

sudo apt-get install python3-dev python3.11-dev python3-setuptools python3-pip python3-distutils
Install Python Virtual Environment

A virtual environment is a tool that keeps a software’s dependencies contained in one area. This way, it avoids disrupting other parts of the computer or server where the software operates.

sudo apt install python3.10-venv python3.11-venv
Set your Default Python Version
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.11 1

Install Software Properties Common

sudo apt-get install software-properties-common

Install MariaDB

ERPNext requires MariaDB to function as its database system.

sudo apt install mariadb-server mariadb-client

Install Redis Server

Now, let’s install Redis Server, which ERPNext uses to manage background tasks and store cache data efficiently. Open your terminal and enter the following command:

sudo apt-get install redis-server

Install other packages

ERPNext’s performance is enhanced by several additional packages, which we’ll install next. These packages are responsible for loading fonts, generating PDFs, and managing other essential resources for our ERPNext setup.

sudo apt-get install xvfb libfontconfig wkhtmltopdf
sudo apt-get install libmysqlclient-dev

Configure MYSQL Server

Setup the server

sudo mysql_secure_installation

Upon executing this command, you’ll encounter a series of prompts on the server. Make sure to follow the subsequent steps carefully to ensure the setup is configured properly.

  • Enter current password for root: (Enter your SSH root user password)
  • Switch to unix_socket authentication [Y/n]: Y
  • Change the root password? [Y/n]: Y
    It will ask you to set new MySQL root password at this step. This can be different from the SSH root user password.
  • Remove anonymous users? [Y/n] Y
  • Disallow root login remotely? [Y/n] Y
  • Remove test database and access to it? [Y/n] Y
  • Reload privilege tables now? [Y/n] Y

Edit MYSQL default config file

vim /etc/mysql/mariadb.conf.d/erpnext.cnf

Add these lines

[mysqld]
innodb-file-format=barracuda
innodb-file-per-table=1
innodb-large-prefix=1
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

[mysql]
default-character-set = utf8mb4
systemctl restart mariadb

Install CURL, Node.js, NPM, and Yarn.

Install CURL

sudo apt install curl

Install Node.js

curl -sL https://deb.nodesource.com/setup_20.x | bash -
sudo apt-get install -y nodejs

Install NPM

npm install -g npm@9.8.1

Install Yarn

sudo npm install -g yarn

Install Frappe Bench

To proceed with the ERPNext installation, switch to the ‘frappe’ user account by entering the following command:

su - frappe
sudo pip3 install frappe-bench

Initialize Frappe Bench

bench init frappe-bench --frappe-branch version-15

Switch directories into the Frappe Bench directory

cd frappe-bench

Next, we need to add the node-sass package, which allows you to compile .scss files to CSS, enhancing your ERPNext themes and styles. Run the following command:

yarn add node-sass

Change user directory permissions

This will give the bench user execution permission to the home directory.

chmod -R o+rx /home/[frappe-user]

Create a New Site

A site is a requirement in ERPNext, Frappe and all the other apps we will be needing to install. We will create the site in this step.

bench new-site [site-name]

Install ERPNext and other Apps

bench get-app erpnext --branch version-15

bench get-app payments --branch version-15

bench --site [site-name] install-app erpnext 


cd frappe-bench

sed -i '/web:/ s/$/ --noreload/' Procfile

pip3 install honcho

bench use [site-name]

bench start

Now you have ERPNext on port 8000. ( http://yourhost.com:8000 )
