SUCCESS: Bench frappe-bench initialized

Switch directory into the Frappe Bench directory,

cd frappe-bench

Change user directory permissions to set execution permission to the home directory,

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

Create a New Site,

bench new-site dev.domainhere.info

It'll prompt you to set the password for Administrator user, can set strong password

Output:

frappe@vps:~/frappe-bench$ bench new-site dev.domainhere.info

Replace dev.domainhere.info with actual domain name

Install ERPNext and other Apps

Download all the apps using below commands,

Download payments app using below command,

bench get-app payments

Download ERPNext app using below command,

bench get-app --branch version-13 erpnext

Install all the apps on our site

bench --site dev.domainhere.info install-app erpnext

Start the bench using below command,

bench start

Note: This instances which are running on develop mode, this will not get started when you restart your server. You will need to run the bench start command every time the server restarts.

In the below steps, we will learn how to deploy the production mode.

Setting ERPNext for Production Usage

Enable Scheduler

bench --site dev.domainhere.info enable-scheduler

Output:

frappe@vps:~/frappe-bench$ bench --site dev.domainhere.info enable-scheduler
Enabled for erp.domainhere.info
frappe@vps:~/frappe-bench$

Disable maintenance mode,

bench --site dev1.domainhere.info set-maintenance-mode off

Setup production config,

sudo bench setup production dev.domainhere.info

Setup NGINX to apply the changes,

bench setup nginx

Install supervisor using below command,

sudo apt install supervisor

Restart Supervisor and Launch Production Mode,

sudo supervisorctl restart all
sudo bench setup production [frappe-user]

If you are prompted to save the new/existing config file, respond with a Y.

When this completes doing the settings, your instance is now on production mode and can be accessed using your IP, without needing to use the port.

This also will mean that your instance will start automatically even in the event you restart the server.

Setup Let’s Encrypt SSL/TLS Certificates with NGINX

Install snapd and then certbot from snapd

apt install snapd -y

snap install core; snap refresh core

snap install --classic certbot

ln -s /snap/bin/certbot /usr/bin/certbot

Obtain the SSL/TLS Certificate

While installing Erpnext the frappe-bench.conf file already created by system, so need to obtain the SSL/TCL Certificate,

sudo certbot --nginx -d dev.domainhere.info

Output:

Congratulations! You have successfully enabled https://dev.domainhere.info  

-------------------------------------------------------------------------------------
IMPORTANT NOTES: 

Congratulations! Your certificate and chain have been saved at: 
/etc/letsencrypt/live/dev.domainhere.info/fullchain.pem 
Your key file has been saved at: 
/etc/letsencrypt/live/dev.domainhere.info//privkey.pem

Navigate Erpnext

Done.
