Odoo has become too Mercenary. Abandoning Odoo and evaluating alternative replacement options. - Trying ERPNext

Unfortunately the opensource community in the last 10 years is killing the goose that laid the golden egg. The new generation of coders who don't know what it was like before opensource, are shooting themselves in the foot by becoming increasingly mercenary in their opensource approach. We saw this with Plone, and now with Odoo. So now we need to find another alternative, one again.
Odoo has become too Mercenary. Abandoning Odoo and evaluating alternative replacement options. - Trying ERPNext

We're evaluating several, and this posting is for evaluating ERPNext as a possible replacement for Odoo and Plone.

 

This is the self-hosted opensource version, not the cloud-hosted paid-for or cloud demo version.

 

 

https://computingforgeeks.com/install-erpnext-erp-system-on-debian-linux/

Debian 11 "bullseye"

apt update

apt upgrade

reboot if needed

 

 

Install Python Tools & wkhtmltopdf

apt -y install git vim libffi-dev python3-pip python3-distutils python3-dev libssl-dev wkhtmltopdf

 

React, node, npm, yarn, etc. (not a fan of the JS "full stack" but required part)

apt -y install nodejs npm redis-server

npm install -g yarn 

 

 

Install nginx

apt -y install nginx

 

Install MariaDB

apt install mariadb-server mariadb-client

 

 

 

vim /etc/mysql/my.cnf

[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

[mysql]
default-character-set = utf8mb4

 

 

Create a database and grant the user all permissions to manage the DB.

systemctl restart mariadb

mysql -u root -p

 

CREATE USER erpnext@localhost IDENTIFIED BY 'password123';
CREATE DATABASE erpnext;
GRANT ALL ON erpnext.* TO 'erpnext'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
QUIT;

 

Install Bench and ERPNext

useradd -m -s /bin/bash erpnext

passwd erpnext

usermod -aG sudo erpnext

 

Switch to erpnext user and update PATH

su - erpnext

vim ~/.bashrc

PATH=$PATH:~/.local/bin/

source ~/.bashrc

 

Create a directory for ERPNext setup and give erpnext user read and write permissions to the directory

sudo mkdir /srv/bench

sudo chown -R erpnext /srv/bench

 

 

Clone Bench code from github using git

As erpnext user,

cd /srv/bench

git clone https://github.com/frappe/bench bench-repo

pip3 install -e bench-repo

 

 

initialize the bench directory with frappe framework installed

from the /srv/bench dir

bench init erpnext

cd erpnext

 

Create a new Frappe site

from /srv/bench/erpnext.

The following command will ask you to provide the MySQL root password and set a new password for the administrator account for the web interface. Then wait for the new Frappe site to be created before proceeding further.

 

bench new-site dev.rpgresearch.com

 

For example:

erpnext@odoo14-dev-web:/srv/bench/erpnext$ bench new-site dev.rpgresearch.com

 

You will see something like:

WARN: bench is installed in editable mode!

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`

MySQL root password:

Starting ERPNext application and accessing the web UI

bench start

 

erpnext@odoo14-dev-web:/srv/bench/erpnext$ bench start 

It will take a bit to load up, and when ready should look like this:

erpnext@odoo14-dev-web:/srv/bench/erpnext$ bench start

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`

 Look for the entry related which port it is listening on, it will look something similar, though may not be identical, to this:

This may need to be reverse proxied via nginx to 172.16.40.50:8000

Do you want to rollback these changes? [y/N]: you proceed.

 

 

If get this error, then rollback, and upgrade node version with npm to newer version (recommend long term support lts latest perhaps).

as erpgnext user:

npm install -g n lts

 

install node version manager

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

log out as the erpnext user, then su back in to reset the environment path to run nvm.

nvm ls-remote v14

Select the lts of this branch: v14.19.3   (Latest LTS: Fermium)

 nvm install v14.19.3 

 

Then try again.

as erpnext user, cd to /srv/bench

bench init erpnext

cd erpnext
