Bench

The bench allows you to setup Frappe / ERPNext apps on your local Linux (CentOS 6, Debian 7 or Ubuntu) machine or a production server. You can use the bench to serve multiple frappe sites.

To do this install, you must have basic information on how Linux works and should be able to use the command-line. If you are looking easier ways to get started and evaluate ERPNext, download the Virtual Machine or take a free trial at FrappeCloud.com.

For questions, please join the developer forum.

Installation

Easy way

Supported for CentOS 6, CentOS 7, Debian 7 and Ubuntu 12.04+

Open your Terminal and enter:

wget https://raw.githubusercontent.com/frappe/bench/master/install_scripts/setup_frappe.sh
sudo bash setup_frappe.sh --setup-production

This script should install the pre-requisites, install bench and setup an ERPNext site.

If you want to develop ERPNext or any Frappe App, you can omit the "--setup-production" part from the command.

Manual Install

Install pre-requisites,

• Python 2.7
• MariaDB
• Redis
• wkhtmltopdf (optional, required for pdf generation)
• Memcached

Install bench as a non root user,

	git clone https://github.com/frappe/bench bench-repo
	sudo pip install -e bench-repo

Note: Please do not remove the bench directory the above commands will create

Installing ERPNext

If you're here to setup ERPNext, continue with ERPNext setup

Migrating from existing installation

If want to migrate from ERPNext version 3, follow the instructions here, https://github.com/frappe/bench/wiki/Migrating-from-ERPNext-version-3

If want to migrate from the old bench, follow the instructions here, https://github.com/frappe/bench/wiki/Migrating-from-old-bench

Basic Usage

• Create a new bench

  The init command will create a bench directory with frappe framework installed. It will be setup for periodic backups and auto updates once a day.

    bench init frappe-bench && cd frappe-bench
  

• Add apps

  The get-app command gets and installs frappe apps. Examples include erpnext and shopping-cart

    bench get-app erpnext https://github.com/frappe/erpnext
  

• Add site

  Frappe apps are run by frappe sites and you will have to create at least one site. The new-site command allows you to do that.

    bench new-site site1.local
  

• Start bench

  To start using the bench, use the bench start command

    bench start
  

  To login to Frappe / ERPNext, open your browser and go to localhost:8000

  The default user name is "Administrator" and password is what you set when you created the new site.

Setting Up ERPNext

To setup a bench that runs ERPNext, run the following commands

cd ~
bench init frappe-bench
cd frappe-bench
bench get-app erpnext https://github.com/frappe/erpnext				# Add ERPNext to your bench apps
bench get-app shopping_cart https://github.com/frappe/shopping-cart	# Add Shopping cart to your bench apps
bench new-site site1.local											# Create a new site
bench frappe --install_app erpnext site1.local						# Install ERPNext for the site
bench frappe --install_app shopping_cart site1.local				# Install Shopping cart for the site

You can now either use bench start or setup the bench for production use.

Updating

On initializing a new bench, a cronjob is added to automatically update the bench at 1000hrs (as per the time on your machine). You can disable this by running bench config auto_update off and run bench config auto_update on to switch it on again. To change the time of update, you will have to edit the cronjob manually using crontab -e.

To manually update the bench, run bench update to update all the apps, run patches, build JS and CSS files and restart supervisor (if configured to).

You can also run the parts of the bench selectively.

bench update --pull will only pull changes in the apps

bench update --patch will only run database migrations in the apps

bench update --build will only build JS and CSS files for the bench

bench update --bench will only update the bench utility (this project)

Running the bench

To run the bench,

For development: bench start

For production: Configure supervisor and nginx

To run the bench, a few services need to be running apart from the processes.

External services

* MariaDB (Datastore for frappe)
* Redis (Broker for frappe background workers)
* nginx (for production deployment)
* supervisor (for production deployment)

Frappe Processes

• WSGI Server

  • The WSGI server is responsible for responding to the HTTP requests to frappe. In development scenario (frappe --serve or bench start), the Werkzeug WSGI server is used and in production, gunicorn (automatically configured in supervisor) is used.

• Celery Worker Processes

  • The Celery worker processes execute background jobs in the Frappe system. These processes are automatically started when bench start is run and for production are configured in supervisor configuration.

• Celery Worker Beat Process

  • The Celery worker beat process schedules enqeueing of scheduled jobs in the Frappe system. This process is automatically started when bench start is run and for production are configured in supervisor configuration.

Production Deployment

You can setup the bench for production use by configuring two programs , Supervisor and nginx. These steps are automated if you pass --setup-production to the easy install script or run sudo bench setup production

Supervisor

Supervisor makes sure that the process that power the Frappe system keep running and it restarts them if they happen to crash. You can generate the required configuration for supervisor using the command bench setup supervisor. The configuration will be available in config/supervisor.conf directory. You can then copy/link this file to the supervisor config directory and reload it for it to take effect.

eg,

bench setup supervisor
sudo ln -s `pwd`/config/supervisor.conf /etc/supervisor/conf.d/frappe.conf

Note: For CentOS 7, the extension should be ini, thus the command becomes

bench setup supervisor 
sudo ln -s `pwd`/config/supervisor.conf /etc/supervisor/conf.d/frappe.ini #for CentOS 7 only

The bench will also need to restart the processes managed by supervisor when you update the apps. To automate this, you will have to setup sudoers using the command, sudo bench setup sudoers $(whoami).

Nginx

Nginx is a web server and we use it to serve static files and proxy rest of the requests to frappe. You can generate the required configuration for nginx using the command bench setup nginx. The configuration will be available in config/nginx.conf file. You can then copy/link this file to the nginx config directory and reload it for it to take effect.

eg,

bench setup nginx
sudo ln -s `pwd`/config/nginx.conf /etc/nginx/conf.d/frappe.conf

Note: When you restart nginx after the configuration change, it might fail if you have another configuration with server block as default for port 80 (in most cases for the nginx welcome page). You will have to disable this config. Most probable places for it to exist are /etc/nginx/conf.d/default.conf and /etc/nginx/conf.d/default.
