ERPNext Setup Pre-requisites:

  • Updated Ubuntu 18.04 Bionic Beaver Linux
  • A user with sudo privileges
  • Python 2.7 [Python3.5+ also supported, but not recommended for production]
  • MariaDB Database Server
  • Nodejs, Nginx, yarn, redis, wkhtmltopdf

Install ERPNext on Ubuntu 20.04/18.04

Let’s start ERPNext installation by making sure our system is updated:

sudo apt update
sudo apt -y upgrade

It is recommended to reboot your system whenever you do upgrade:

sudo reboot

Step 1: Install Python Tools & wkhtmltopdf

Start the installation process by ensuring all Python build packages required to build and setup ERPNext are installed:

--- Ubuntu 20.04 ---
sudo apt -y install vim libffi-dev python3-pip python3-dev  python3-testresources libssl-dev wkhtmltopdf

--- Ubuntu 18.04 ---
sudo apt -y install vim libffi-dev python-pip python-dev libssl-dev wkhtmltopdf

Step 2: Install Redis and Node.js

To install Redis and Node.js on Ubuntu 20.04/18.04, run the commands:

sudo curl --silent --location https://deb.nodesource.com/setup_10.x | sudo bash -
sudo apt -y install gcc g++ make nodejs redis-server
sudo npm install -g yarn

Step 3: Install Nginx web server and MariaDB Database server

Next step is to Nginx and MariaDB for serving ERPNext and storing database data respectively.

Install Nginx using:

sudo apt -y install nginx

For installation of MariaDB server on Ubuntu:

sudo apt install mariadb-server

Change authentication plugin.

$ sudo mysql -u root
USE mysql;
UPDATE user SET plugin='mysql_native_password' WHERE User='root';
FLUSH PRIVILEGES;
EXIT;

Ensure you have the following settings for mysqld and mysql client as provided:

$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf

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

[mysql]
default-character-set = utf8mb4

After the installation of MariaDB database server, you should create a database for erpnext user.

sudo systemctl restart mariadb

Step 4: Install Bench and ERPNext

A bench is a tool used to install and manage ERPNext on your Ubuntu system. We will create a user that will run the ERPNext system, then configure the system.

sudo useradd -m -s /bin/bash erpnext
sudo passwd erpnext
sudo usermod -aG sudo erpnext

Update your PATH.

$ sudo su - erpnext
$ tee -a ~/.bashrc<<EOF
PATH=\$PATH:~/.local/bin/
EOF
$ 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

Next switch to erpnext user and install the application:

sudo su - erpnext
cd /srv/bench

Clone Bench code from github using git

$ git clone https://github.com/frappe/bench bench-repo
Cloning into 'bench-repo'...
remote: Counting objects: 5832, done.
remote: Compressing objects: 100% (43/43), done.
remote: Total 5832 (delta 20), reused 20 (delta 6), pack-reused 5783

Resolving deltas: 100% (3720/3720), done.

Now install bench using pip command:

--- Ubuntu 20.04 ---
pip3 install -e bench-repo

--- Ubuntu 18.04 ---
pip install -e bench-repo

The next step is to initialize the bench directory with frappe framework installed:

cd /srv/bench
bench init erpnext

A sample output is:

INFO:bench.utils:setting up backups
SUCCESS: Bench erpnext initialized

Create a new Frappe site.

$ cd erpnext
$ bench new-site  erp.computingforgeeks.com 
MySQL root password: 

Installing frappe...
Updating DocTypes for frappe        : [========================================]
Updating country info               : [========================================]
Set Administrator password: <input-admin-pass>
Re-enter Administrator password: <confirm-admin-pass>
*** Scheduler is disabled ***

The above command will ask you to provide the MySQL root password and set a new password for the administrator account for the web interface. Wait for the new Frappe site to be created, then

Step 5: Starting ERPNext application and access UI

Once the application is deployed, you can start it using the command:

$ bench start

When the program is running, you should get:

12:49:02 redis_queue.1    | 30491:M 18 Jul 12:49:02.630 * Ready to accept connections
12:49:03 socketio.1       | listening on *: 9000
12:49:08 web.1            |  * Running on http://0.0.0.0:8000/ (Press CTRL+C to quit)
12:49:09 web.1            |  * Restarting with inotify reloader
12:49:09 watch.1          | yarn run v1.7.0
12:49:09 watch.1          | $ node rollup/watch.js
12:49:09 web.1            |  * Debugger is active!
12:49:09 web.1            |  * Debugger PIN: 849-623-753
12:49:10 watch.1          | 
12:49:10 watch.1          | Rollup Watcher Started
12:49:10 watch.1          | 

From the output, you can confirm the service is running on http://0.0.0.0:8000/. To access the web interface, open the server IP address and port http://ip-address:8000.

Step 6: Configure Nginx and Supervisord

Install supervisor:

sudo apt -y install supervisor

Run production configuration script:

$ sudo bench setup production erpnext
supervisor.conf already exists and this will overwrite it. Do you want to continue? [y/N]: y
Port configuration list:

Site erp.computingforgeeks.com assigned port: 80
nginx.conf already exists and this will overwrite it. Do you want to continue? [y/N]: y
INFO:bench.utils:sudo /usr/bin/supervisorctl reread
No config updates to processes
INFO:bench.utils:sudo /usr/bin/supervisorctl update
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
INFO:bench.utils:sudo systemctl reload nginx

Generated Nginx file is placed under: /etc/nginx/conf.d/erpnext.conf and supervisor config file is /etc/supervisor/conf.d/erpnext.conf.

Open your application domain configured to login- //erp.computingforgeeks.com

You should get a page to login. Use the username Administrator and the password you provided during setup.

Select the language of your choice and click “Next“. Next select country, it will fill currency automatically.

Add the first user with email and password and click “Complete Setup” button.

When done, you should get to ERPNext web dashboard.
