Installing ERPNext version 15 on Ubuntu 23+

( If Ubuntu version of your instance is 20+, most probably your Python is 3.8 and node is 12. For Frappe and ERPNext version 14, it is mandatory to have Python 3.10 and Node 16+. We have explained the upgrading procedures in this document ( https://cloud.erpgulf.com/blog/support-forum/erpnext-upgrade-from-version-13-to-version-14-ubnutu . Use that document to prepare server. Please do that and come back here to continue. If you are not sure about Ubuntu version please type this command cat /etc/os-release )

**A video version we previously uploaded for Version 14 can tremendously help on ERPNext version 15 also. Please watch it here. ( https://youtu.be/RU9lXV1sTlI )

**If you are using beta version of version-15 , ( bench switch-to-branch version-15 frappe erpnext --upgrade

bench update --patch --reset

bench update --reset

)

( commands are in blue letters )

apt-get update -y

init 6  ( will restart )

sudo apt-get install python3-dev python3.11-dev python3-setuptools python3-pip python3-distutils software-properties-common xvfb libfontconfig wkhtmltopdf libmysqlclient-dev -y

sudo apt-get install python3.11-venv -y

sudo apt install python-is-python3 -y

Test python installation and version at this stage

python3 -V ( result Python 3.11.X )

python -V ( resulat Python 3.11.X )

--------------Node 21 installation ---------

sudo apt install -y ca-certificates curl gnupg

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_21.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

sudo apt update

sudo apt install nodejs -y

node --version

v21.1.0

--------------------------------------------

apt-get install nodejs redis-server -y

apt-get install cron git -y

Test NODE version at this stage, to make sure you have properly installed Node-16

node --version ( result must be above : v20.XXX )

npm install -g yarn

npm install -g npm@10.2.4 ( this may vary, check the output of previous command )

Check NPM version at this statem and make sure you installed npm properly

npm --version ( result must be above : 9.XX.X )

Install Mariadb

apt-get install mariadb-server mariadb-client -y

check MariaDB version here

mariadb --version ( result must be mariadb Ver 15.1 Distrib 10.6.7-MariaDB, )

Set Mariadb security features correct

mysql_secure_installation

Enter current password for root (enter for none): Press your [Enter] key, there is no password set by default

Switch to unix_socket authentication N

Set root password? [Y/n] Y

New password:

Re-enter new password:

Remove anonymous users? [Y/n] Y

Disallow root login remotely? [Y/n] Y

Remove test database and access to it? [Y/n] Y

Reload privilege tables now? [Y/n] Y

Set Mariadb formats.

vim /etc/mysql/mariadb.conf.d/erpnext.cnf

Add these lines

[mysqld]

innodb-file-format=barracuda

innodb-file-per-table=1

innodb-large-prefix=1

character-set-client-handshake = FALSE

character-set-server = utf8mb4

collation-server = utf8mb4_unicode_ci

[mysql]

default-character-set = utf8mb4

systemctl restart mariadb

Next, we are going to create a user called "erpgulf" . Set its password, usermod, and sudo prvilege.

useradd -m -s /bin/bash erpgulf

passwd erpgulf

usermod -aG sudo erpgulf

su - erpgulf

Now you are inside the new user. Now let us set it's path.

vim ~/.bashrc

add this line

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

source ~/.bashrc

su - erpgulf

sudo mkdir /opt/bench

sudo chown -R erpgulf:erpgulf /opt/bench

cd /opt/bench

yarn add node-sass

Check yarn and node-sass at this point

yarn --version ( result must be:1.22.19 )

/opt/bench/node_modules/.bin/node-sass -v ( result must be: node-sass 9.0.1 (Wrapper) [JavaScript]

libsass 3.5.5 (Sass Compiler) [C/C++] )

npm node-sass -v ( Result must be: 8.19.1 )

Check pip3 version

pip3 -V ( Result must be pip 23.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10) )

pip -V ( Result must be pip 23.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10) )

Now we are entering to Frappe installation. Before that finish all the following tests ( in violet letters ) . Otherwise installation will fail

****************************************************

python -V ( result Python 3.11.4 )

node --version ( result must be : v20.17.0 )

npm --version ( result must be : 9.8.1 )

mariadb --version ( result must be mariadb Ver 15.1 Distrib 10.6.7-MariaDB, )

yarn --version ( result must be:1.22.19 )

/opt/bench/node_modules/.bin/node-sass -v ( result must be: node-sass 9.0.1 (Wrapper) [JavaScript] libsass 3.5.5 (Sass Compiler) [C/C++] )

npm node-sass -v ( Result must be: 9.8.1 )

pip3 --version ( Result must be pip 23.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10) )

pip --version ( Result must be pip 23.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10) )

redis-server --version (Redis server v=7.0.16 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=a3fdef44459b3ad6)

wkhtmltopdf -V ( wkhtmltopdf 0.12.6 )

git -v (git version 2.39.1)

***************************************************

Once you start using pip , you may get error "This environment is externally managed" in that case, either use following command, or use pipx

1. remove file /usr/lib/python3.x/EXTERNALLY-MANAGED,

sudo apt install pipx

pip3 install frappe-bench ( or pipx install frappe-bench , if you havent removed EXTERNALLY-MANAGED )

sudo apt install python3.10-venv

bench init frappe-bench --frappe-branch version-15

cd frappe-bench

 sed -i '/web:/ s/$/ --noreload/' Procfile

pip3 install honcho

 bench start &

While you are running the above command , you can see below

* Running on http://127.0.0.1:8000

14:29:30 web.1      | * Running on http://45.56.78.183:8000 (Press CTRL+C to quit)

Also, you can telnet to port 8000 to this server from outside.

telnet v14.erpgulf.com 8000 ( port will show open )

Press CTRL+C to return to CLI

bench new-site yourhost.erpgulf.com

At this point we have a frappe site running - bench start and you will get the website on port 8000. But ERPNext not yet installed. Let's continue

bench get-app erpnext --branch version-15

bench get-app payments --branch version-15

bench get-app hrms --branch version-15

 bench --site yourhost.erpgulf.com install-app erpnext

( before running hrms, make sure you are running bench in the background. use this command bench start &

bench --site yourhost.erpgulf.com install-app hrms

Now you have ERPNext on port 8000. ( http://yourhost.example.com:8000 )

You can run the setup-wizard on the browser.

----- NOW deploy it in production mode - on nginx server -------
