Ltd., based out of India's financial capital . Enterprise Resource Planning FOSS Mumbai ERPNext is the best among FREE ERPs available in 2023 such as Dolibarr, Odoo, etc. In 2018, ERPNext was rated among the top 5 user-friendly ERP systems by Gartner, surpassing Microsoft, SAP, Bexio, and several other ERP systems. ERPNext is available as a self-hosted software for your small to medium business to install on your own servers helping you to maintain your data privacy without paying a dime for the licensing fee (except the server costs). However, it is not easy for non-technical users to get the hang of it. My ERPNext installation guide below is an easy-to-follow set of instructions helping you to easily install ERPNext version 14 on a 4GB droplet hosting Ubuntu 22.04 LTS. Let's get started:- Create a new droplet on Digitalocean with Ubuntu 22.04 Signup for a new account or log in to your already existing account on Digitalocean. Once you are on the page of your Digitalocean account, click on the green "Create" button on the top right and select " from the dropdown. This will take you to the page. "projects" droplet" "Create Droplets" On the page you can configure your server by following the instructions on this page such as:- "Create Droplet" I usually pick Bengaluru or Singapore because those are the nearest to my location. Your server's data center: I usually prefer the latest Ubuntu LTS. Currently, the LTS version of Ubuntu is 22.04. An operating system image for your server: I usually pick and with 4GB RAM for a new ERPNext installation. The CPU size for your server: Basic Regular I would recommend a minimum RAM for ERPNext of 2GB with 4GB SWAP. After you have configured the server add your key for easy access to your server from your PC. SSH If you are on Windows then you can use Putty to access your server else you can simply run on your Linux terminal or Mac Command. ssh root@-your-droplet-ip-address Finally, hit the button to create a new server for your ERPNext 14 installation. "Create Droplet" Install all the preliminary software required to install Frappe and ERPNext To install Frappe and ERPNext we need to install a few essential software such as , , , etc. gcc python mariadb Follow the instructions below:- Login to your server from your PC for easy access. As I use ArchLinux thus I just have to open a window and then just into my server. Terminal ssh Replace my server's IP address with your droplet's IP address. Note:- I will delete my server post-publishing this article. $ssh root@-your-droplet-ip-address Add SWAP to your server Though 4GB RAM is enough for an ERPNext instance, however, just in case there might be a RAM-eating process so to keep our instance running it would be nice to have some SWAP. I usually prefer a SWAP of 2x of your server RAM but you can add a 4GB swap too to save disk space. . Follow the guide here to add swap: https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-22-04 Verify if you already have a SWAP:- Create an 8GB SWAP:- Make your SWAP permanent so that when you restart your server then also you will have your SWAP. Adjust or tune your SWAP settings and :- swappiness vfs_cache_pressure Update your server and install the LOCALES $ sudo apt update $ sudo apt upgrade After you have completely upgraded your Ubuntu 22.04 server, then you can install which are required by ERPNext. LOCALES $ sudo localectl set-keymap us && sudo localectl set-locale LANG=en_US.utf8 If you get an error then you can follow the instructions given at to resolve this error and continue with installing ERPNext 14.
