Install ERPNext on Ubuntu VM with Graviton2 (experimental)

Installing ERPNext on Kubernetes has advantages in scalability, stability, and elasticity. However, installing on a VM can also be beneficial:

  • easier debugging with “ad-hoc” techniques
  • potential use of AWS Arm Graviton2 instances (too many issues, Frappe will not support it)
  • remote debugging using Code Server or Gitpod

Install ERPNext version-13 and Create a Site using Easy Install Script

References:

Note: This will install MariaDB locally, which is OK. Later you can dump & restore the data from local MariaDB to AWS MariaDB, then purge the local MariaDB installation.

  1. [If you install with Pulumi and/or use Lightsail User Data to do initial update] Wait until apt-get -y full-upgrade completes:
    sudo ps -ef | grep apt
    Make sure there is no apt* running.
  2. Install Prerequisites to run Easy Install Script.
# python3-minimal and python3-setuptools already installed by ubuntu 20.04
sudo apt-get -y install python3-minimal build-essential python3-setuptools

Warning: Unsupported configuration: In Arm 64-bit, these Python packages will need to be built from source, and the needed devel packages:

  • psycopg2 <- libpq-dev & libssl-dev
  • pandas
  • pycountry
# workaround for aarch64
sudo apt-get -y install libpq-dev libssl-dev

2. Inside /home/ubuntu, download Bench’s Easy Install script, apply our fixes, then execute it. The following command will install requirements, install bench, initialize frappe-bench folder and install frappe app version-13-beta, install erpnext app version-13-beta, and create a site named site1.local with ERPNext.

wget https://raw.githubusercontent.com/frappe/bench/develop/install.py
# apply: https://github.com/frappe/bench/pull/1079
# apply: https://github.com/frappe/bench/pull/1086
# apply: https://github.com/frappe/bench/pull/1085
# apply: 
sudo python3 install.py --production --user frappe --version 13 --frappe-branch version-13-beta --erpnext-branch version-13-beta

If you want to install the first site a manually, use --without-site. Note: –without-site is buggy (PR #1087), it still runs Ansible task setup_erpnext.yml:13 & 17.

If you want development environment, replace --production with --develop but make sure to put --user frappe, otherwise it will install bench using the current user.

Bench + Frappe + ERPNext has been successfully installed!

Excluding troubleshooting & errors, it will take about 60 minutes to complete on m6g.medium Singapore. If you use –develop, you’ll need to run bench start. If you use –production, it will setup supervisor and runs it on port 8000. Now you can access it on http://0.0.0.0:80/.

The resulting /home/frappe folder structure is:

Easy Install using –production:

  • sets up swap.
  • It installs these servers/system packages: ansible, MariaDB, nginx, redis, supervisor. It then uses bench setup * to setup configuration for these components.
  • Optional: bench setup can also generate systemd configuration.

If you didn’t want to create site site1.local, drop it by:

bench drop-site --force site1.local

AWS Application Load Balancer and SSL

Note: bench setup can configure lets-encrypt with nginx.

To support SSL, you can use AWS Application Load Balancer, which supports multiple certificates on the same HTTPS listener using SNI.

For security groups, make sure that both the ALB and your EC2 instance belong to “default” security group so the ALB can access the EC2 instance.

The “WARN: bench is installed in editable mode!” is because bench was modified (to install wkhtmltox).

Key error here is:

TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘list’

caused by get_frappe_commands() returning None.

You can check by running command directly:

[email protected]:~$ sudo -H -u frappe bash
[email protected]:~$ cd /home/frappe/frappe-bench
[email protected]:~/frappe-bench$ ls
apps  config  env  logs  patches.txt  Procfile  sites

WARN: bench is installed in editable mode!

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`

This happened because somehow installation of frappe-bench/apps/frappe failed. Manually, it can be fixed by running:

env/bin/pip install -q  -e ./apps/frappe

Then you’ll see why:

ERROR: Could not install packages due to an EnvironmentError: [Errno 28] No space left on device

Complete steps for resize: (you don’t have to stop your instance, all of these steps can be done “online”, meaning root partition still in use)

  1. Using EC2 Management Console, resize the EBS volume.
  2. sudo growpart /dev/nvme0n1 1
  3. sudo resize2fs /dev/nvme0n1p1

Coming back to “env/bin/pip install -q -e ./apps/frappe”.

Seems like something was wrong during bench/playbooks/roles/bench/tasks/main.yml on “python3 bench init for develop/production”:

  - name:  python3 bench init for develop
    command: bench init {{ bench_path }} --frappe-path {{ frappe_repo_url }} --frappe-branch {{ frappe_branch }} --python {{ python }}
    args:
      creates: "{{ bench_path }}"
    when: not bench_stat.stat.exists and not production

  - name: python3 bench init for production
    command: bench init {{ bench_path }} --frappe-path {{ frappe_repo_url }} --frappe-branch {{ frappe_branch }} --python {{ python }}
    args:
      creates: "{{ bench_path }}"
    when: not bench_stat.stat.exists and production

Indeed, it was error but it still continued as “SUCCESS: Bench /home/frappe/frappe-bench initialized”:

SUCCESS: Bench /home/frappe/frappe-bench initialized

Conclusion: Installing frappe app failed due to missing pg_config executable, but bench init wrongly continues instead of stopping and throwing error (#1082). Apply PR #1083.

Further, the problem is psycopg2-binary has no binaries for Arm, see #1084.

TL:DR:

sudo apt -y install libpq-dev libssl-dev

After that, bench init will work. 96s using m6g.medium Singapore.

Done in 96.11s.
SUCCESS: Bench /home/frappe/frappe-bench initialized

Switch to ERPNext 13

Hendy tried on Arm64 architecture processor / AWS Graviton2. If all works properly it should be as simple as:

# Note: better update 'bench' first
pip3 install --upgrade frappe-bench

# Update frappe, erpnext, and lovia
bench switch-to-branch version-13 frappe erpnext lovia --upgrade
bench update
bench build

But maybe you will need to install frappe manually, due to problem with psutil. How to install frappe manually:

env/bin/pip install -e ./apps/frappe

Then during bench update, you’ll get:

error /home/frappe/frappe-bench/apps/frappe/node_modules/phantomjs-prebuilt: Command failed.
Exit code: 1
Command: node install.js
Arguments:
Directory: /home/frappe/frappe-bench/apps/frappe/node_modules/phantomjs-prebuilt
Output:
PhantomJS not found on PATH
Unexpected platform or architecture: linux/arm64
It seems there is no binary available for your platform/architecture

It will seem stuck for about 5 minutes then resume, Hendy’s not sure if that works properly or we need to build our own phantomjs?

So far, ERPNext v13 seems to work. However, we don’t know if there are specific features that aren’t working (Vue related?).

Since phantomjs and phantomjs-prebuilt is no longer in development, and they don’t support Arm64 for now; as long as ERPNext still depends on phantomjs, don’t install ERPNext on Arm64! Existing installations should be migrated to x64.

Recommendation is we should switch back to x64, otherwise no guarantee it won’t break in the future.
