ERPNext 14¶

long term goal is to run ERPNext in a podman-pod. Maybe this can be a first stepping stone:
https://piotrkrzyzek.com/how-to-setup-self-host-erpnext-in-docker-without-treafik-nginx-only/
until then we use Bitnami VMs.

Bitnami based on Debian 11¶

out of the box ERPNext is installed. This describes what else can/needs to be done:

convert VirtualBox-ova to be used with KVM¶

untar .ova

tar xvf bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami.ova

convert .vmdk to .qcow2 while showing 'progress'

qemu-img convert -p -f vmdk -O qcow2 \
  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.vmdk \
  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.qcow2

this is a sample virsh dumpxml with a bridged interface

set static IP address¶

taken from https://docs.bitnami.com/virtual-machine/faq/configuration/configure-static-address/

check link and current IPs

sudo ifconfig

cd /etc/systemd/network
sudo touch 25-wired.network

add following lines

[Match]
Name=ens3

[Network]
Address=HOST-IP-ADDRESS
Gateway=GATEWAY-IP-ADDRESS

restart service

sudo systemctl restart systemd-networkd.service
sudo systemctl enable systemd-networkd

activate SSH-Server¶

taken from https://docs.bitnami.com/virtual-machine/faq/get-started/enable-ssh/

sudo rm -f /etc/ssh/sshd_not_to_be_run
sudo systemctl enable ssh
sudo systemctl start ssh

... password-based SSH auth (are you serious?)¶

maybe ok for testing ..
taken from https://docs.bitnami.com/virtual-machine/faq/get-started/enable-ssh-password/

edit /etc/ssh/sshd_config and add/modify the following line

  PasswordAuthentication yes

restart SSH server

  sudo systemctl restart ssh

... and of course cert-based ..¶

from the remote machine just

ssh-copy-id bitnami@example.com

modify keyboard layout¶

taken from https://docs.bitnami.com/virtual-machine/faq/configuration/configure-keyboard/

  sudo apt install keyboard-configuration console-setup

alias ll¶

for everyone .. taken from https://www.server-world.info/en/note?os=Debian_11&p=initial_conf&f=2

sudo vim /etc/profile.d/command_alias.sh

# create new file
# add alias you'd like to set
alias ll='ls $LS_OPTIONS -l'
# alias l='ls $LS_OPTIONS -lA'
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'

source /etc/profile.d/command_alias.sh

Install the Wkhtmltopdf extension¶

taken from https://docs.bitnami.com/aws/apps/erpnext/configuration/install-wkhtmltopdf/

alternatively it should be possible to install via something like bench install wkhtmltopdf

find /opt/bitnami/common/bin -name fc-* | sudo xargs -I {} mv {} {}.bak
sudo apt install zlib1g fontconfig libxrender1 libfreetype6 libxext6 libx11-6

Download the latest version of the package from the Wkhtmltopdf project releases page and install it. Replace the X.Y.Z and PLATFORM placeholders with the correct version and platform strings from the release filename.

https://github.com/wkhtmltopdf/wkhtmltopdf/releases/

as of 2023-02-16 https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.buster_amd64.deb

wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/X.Y.Z/wkhtmltox_X.Y.Z.PLATFORM.deb
sudo apt install -f ./wkhtmltox_X.Y.Z.PLATFORM.deb
sudo /opt/bitnami/ctlscript.sh restart

install alternative way?¶

without QT but with virtual X11-Server

https://packages.debian.org/bullseye/xvfb
https://installati.one/debian/11/wkhtmltopdf/
https://packages.debian.org/stable/wkhtmltopdf

needs some testing

Troubleshooting PDF formating issues¶

taken from https://discuss.frappe.io/t/pdf-alignment-problem/34425/7

set the IP-adr. in site_config.json

vim /opt/bitnami/erpnext/frappe-bench/sites/erpnext/site_config.json

replace http:localhost with the https://hostname-ip:443

 "host_name": "https://192.168.41.131:443" 

Troubleshooting (is just a reminder ... I stumbled across but didn't do it, as there were no related issues yet)¶

If you experience issues with display resolution on Linux platforms, they could be related to the xfonts-75dpi or xfonts-100dpi packages. Uninstall them by executing:

sudo dpkg --remove --force-depends xfonts-75dpi
sudo dpkg --remove --force-depends xfonts-100dpi

install weasyprint¶

taken from https://packages.debian.org/bullseye/weasyprint

sudo apt install weasyprint

automatic backup of ERPNext¶

sudo vim /usr/local/bin/erpnext-backup.sh

#!/bin/bash -l

# there is some 'magic' in the shebang, the '-l' is invoking the environment of the calling user (in this case 'bitnami')
# JKE 2023-08-24
cd /opt/bitnami/erpnext/frappe-bench
# JKE 2023-10-13 backup sites individually and with files
# bench backup-all-sites
# bench --site erpnext backup --with-files
# bench --site erpnext set-maintenance-mode on
bench --site all backup --with-files
# bench --site erpnext set-maintenance-mode off
# bench --site all backup --with-files --compress --backup-path /var/cache/myerpnext.bak/
# /JKE 2023-10-13

sudo chmod +x /usr/local/bin/erpnext-backup.sh

sudo vim /etc/cron.d/erpnext-backup

# JKE 2023-08-24
#
#    min  hr   dom  month dow     user    command
#    -    -    -    -     -
#    |    |    |    |     |
#    |    |    |    |     +-day of week (0-7) sunday=0 or 7
#    |    |    |    +---------month (1-12)
#    |    |    +----------------day of month (1-31)
#    |    +-----------------------hour (0-23)
#    +------------------------------min (0-59)
#
#     32   13   *    *     *       bitnami  /usr/local/bin/erpnext-backup.sh >> /home/bitnami/erpnext-backup.log 2>&1
     15   18   *    *     *       bitnami  /usr/local/bin/erpnext-backup.sh

here is again some 'magic', there is no MTA available. So any output from the cron-job gets discarded.
use the upper construct to debug and append the output to /home/bitnami/erpnext-backup.log

the backups are stored in /opt/bitnami/erpnext/frappe-bench/sites/erpnext/private/backups

retrieve backups from external machine¶

rsync is not installed by default ..

sudo apt-get install rsync

from the external machine, just invoke like

rsync --verbose --progress --stats --recursive bitnami@example.com:/opt/bitnami/erpnext/frappe-bench/sites/erpnext/private/backups/* .

check ERPNext version¶

cd /opt/bitnami/erpnext/frappe-bench
bench version

migrate ERPNext to new server¶

backup¶

cd /opt/bitnami/erpnext/frappe-bench
bench backup-all-sites

files are saved very deep

cd /opt/bitnami/erpnext/frappe-bench/sites/erpnext/private/backups/

restore¶

copy files to new server into /home/bitnami

gunzip yyyymmdd_hhmmss-erpnext-database.sql.gz

connect to MariaDB (password is the same as application-password)
taken from https://docs.bitnami.com/general/apps/erpnext/get-started/connect-mariadb/

mysql -u root -p

DROP DATABASE bitnami_erpnext;
\q

as of 2023-02-07 restore seems not to work following the instructions

cd /opt/bitnami/erpnext/frappe-bench/
bench restore /home/bitnami

vanilla install based on Ubuntu¶

backup and load into test-site¶

To create a staging site from a production site backup:

cd <frappe/erpnext Verzeichnis>
mkdir ~/backup/

bench --site prod.example.net set-maintenance-mode on
bench --site prod.example.net set-config pause_scheduler 1
bench --site prod.example.net backup --with-files --compress --backup-path ~/backup/ 
# notice: Database Public & Private from stdout
bench --site prod.example.net set-maintenance-mode off

restore into other Staging instance:

bench new-site staging.example.net
bench --site staging.example.net set-maintenance-mode on

bench --site staging.example.net restore ~/backup/YYYYMMDD_HHMMSS-prod.example.net-database.sql.gz
  --with-public-files  ~/backup/YYYYMMDD_HHMMSS-prod.example.net-files.tar.gz
  --with-private-files ~/backup/YYYYMMDD_HHMMSS-prod.example.net-private-files.tar.gz
  MySQL root password:

bench --site staging.example.net mute_emails true
bench --site staging.example.net set-maintenance-mode off
rm -r ~/backup/
