Install and Deploy Odoo 12 on Ubuntu 22.04 Server

In this post, I will guide you through the 6 steps to install Odoo 12 running with Python 3.7 and 3.8 on Ubuntu 22.04 Server with PostgreSQL 10 and PostgreSQL 12.

Please note that if you are seeking for installing other Odoo versions, you could read other posts of mine for that:

Of, if you are an Odoo developer, you may interest in How to setup Odoo development environment on Ubuntu 22.04.

Executive Summary

In this post, I will guide you through 6 steps to install Odoo 12 on Ubuntu 22.04 server to achieve the following:

Odoo 12 running with Python 3.7:
- Running Unix User: odoo12_37
- PostgreSQL version: 10
- HTTP port: 8089, so that users can access it with a web browser with an address like http://your_ip:8089
Odoo 12 running with Python 3.8
- Running Unix User: odoo12_38
- PostgreSQL version: 12
- HTTP port: 8099, so that users can access it with a web browser with an address like http://your_ip:8099
Each of the 2 above (aka each instance) will run as a service with autostart.
The instances will also be isolated in a dedicated environment
They will also be set with a secured master password to protect their database. Users having master password will be able to create/delete/backup/restore databases

Step1 – Create Odoo Running Users and Group

For security, we should run Odoo instances under separate Linux user accounts that have the following specifications:

For Odoo 12 running Python 3.7:
- Account Name: odoo12_37
- Home Directory: /home/odoo12_37
For Odoo 12 running Python 3.8:
- Account Name: odoo12_38
- Home Directory: /home/odoo12_38
The user accounts will not be able to login for security purpose. They should also be system accounts under which daemons and other processes could run;
The user accounts will belong to a group that has access to Odoo 12 source code (i.e. odoo);

Create Unix group

Run the following command to create the group odoo:

sudo addgroup odoo

Create User odoo12_37

Run the following command to create the user account odoo12_37 and add it to the group odoo:

sudo adduser odoo12_37 --system \
--home=/home/odoo12_37 --disabled-login \
--disabled-password --ingroup odoo

Create User odoo12_38

Run the following command to create the user account odoo12_38 and add it to the group odoo:

sudo adduser odoo12_38 --system \
--home=/home/odoo12_38 --disabled-login \
--disabled-password --ingroup odoo

Step 2 – Install PostgreSQL for Odoo 12

I have not fully tested Odoo 12 with the latest version of PostgreSQL which is PostgreSQL 14 that comes fresh with Ubuntu 22.04 but I believe it should work. However, as discussed in the section Executive Summary, we are going to install PostgreSQL 10 and 12. If you want other versions of PostgreSQL, you can follow another post of mine to install multiple PostgreSQL versions on Ubuntu 22.04 in case you want another version of PostgreSQL.

Adding official PostgreSQL PPA

As Ubuntu 22.04 has no idea about the PostgreSQL versions other than 14, we need to add the official PPA from PostgreSQL author

# Create the file repository configuration: 
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list' 
# Import the repository signing key: 
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/postgresql.gpg 
# Update the package lists: 
sudo apt-get update

As usual, we should update the system before installing anything:

sudo apt dist-upgrade

Install PostgreSQL 10 and 12

sudo apt install postgresql-10
sudo apt install postgresql-12

After the installation is completed, and I assume that you did not have any postgreSQL installed before, the listening port of the newly installed PostgreSQL clusters will be:

PostgreSQL 10: 5432
PostgreSQL 12: 5433

In case you have other versions of PostgreSQL running and you want to re-arrange the ports assignment, please follow the tutorial on changing PostgreSQL ports.

Create Database Roles

In this section, we will create database SQL roles having the same name as the unix user accounts’ so that Odoo will be able to authenticate PosgreSQL using ident method (without using password):

Odoo 12 running Python 3.7 will connect PostgreSQL 10 on port 5432 using the role odoo12_37,
Odoo 12 running Python 3.8 will connect PostgreSQL 12 on port 5433 using the role odoo12_38

Create Role odoo12_37

The command below will create a role named odoo12_37 in PostgreSQL 10 listening on port 5432:

sudo -u postgres createuser odoo12_37 --interactive -p 5432

When asked during the interative session, please input as follow:

Create Role odoo12_38

The command below will create a role named odoo12_38 in PostgreSQL 12 listening on port 5433:

sudo -u postgres createuser odoo12_38 --interactive -p 5433

When being asked during the interactive session, please input as follow:

Step 3 – Download Odoo 12 source code from GitHub

In this section, we will download the Odoo 12 source code from GitHub and implement security policy for read access for the users in the group odoo.

To download the source code of Odoo 12 from GitHub, just run the command below to clone it using git over HTTP:

git clone -b 12.0 https://github.com/odoo/odoo.git /opt/odoo/odoo12

Or, you may clone the repository from GitHub over SSH for better performance and security using the following command:

git clone -b 12.0 git@github.com:odoo/odoo.git /opt/odoo/odoo12

Depending on your internet connection speed, the process may take a few minutes or more. Please be patient or open another session to work for the next steps of installing Python in parallel.

After the process is completed, you will find the Odoo 12 source code in the directory /opt/odoo/odoo12/.

Now, secure your source code to allow only the users of the group odoo to read it by changing group permission to odoo.

sudo chown -hR root:odoo /opt/odoo/odoo12

Step 4 – Install Python 3.7 and 3.8

As discussed, Odoo 12 supports Python 3.7 and 3.8 officially. However, the Python version comes fresh with Ubuntu 22.04 is 3.10 so we need to install Python 3.7 and 3.8 ourselves. You can follow the instructions on how to install multiple versions of Python to complete this step. In summary, you could:

Add Deadsnakes PPA

sudo add-apt-repository ppa:deadsnakes/ppa

Install Python 3.7 and its Virtual Environment tool

As we need to create an isolated Python environment for Odoo 12 to run to avoid to break existing things, we need to install Python Virtual Environment Tool also. Here is the command to install both Python 3.7 and its virtual environment tool:

sudo apt install python3.7 python3.7-venv

Now, run the command below to verify if Python 3.7 is properly installed:

python3.7 -V

You should see output as below:

Verify if Python 3.7 is properly installed

Install Python 3.8 and its Virtual Environment tool

sudo apt install python3.8 python3.8-venv

Now, issue the command below to verify if Python 3.8 is properly installed:

python3.8 -V

You should see output as below

Verify if Python 3.8 is properly installed

Step 5 – Install Odoo 12

Prerequisites

Install Ubuntu software and packages that are required to run Odoo 12 later:

sudo apt install python3.7-dev python3.8-dev \
build-essential libsass-dev libjpeg-dev \
libjpeg8-dev libldap-dev libldap2-dev \
libpq-dev libsasl2-dev libxslt1-dev zlib1g-dev

Install wkhtmltopdf

Odoo generates PDF from HTML, that’s why we need the wkhtmltopdf.

Download wkhtmltopdf:

wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-2/wkhtmltox_0.12.6.1-2.jammy_amd64.deb

Install wkhtmltopdf:

sudo dpkg -i wkhtmltox_0.12.6.1-2.jammy_amd64.deb
# force install dependencies
sudo apt -f install -y

Install Odoo 12 with Python 3.7 and PostgreSQL 10

Create Odoo 12 Python 3.7 Virtual Environment

Create parent folders for Odoo 12 with Python 3.7 virtual environment:

sudo mkdir -p /python-venv/3.7/odoo12

Secure the virtual environment:

sudo chown -hR odoo12_37:odoo /python-venv/3.7/odoo12

Switch the current user account to odoo12_37’s bash:

sudo su - odoo12_37 -s /bin/bash

Create virtual environment:

python3.7 -m venv /python-venv/3.7/odoo12

Install required Python libraries for Odoo 12

Activate the virtual environment we’ve created in the above:

source /python-venv/3.7/odoo12/bin/activate

As usual, we need to upgrade pip to its latest version for the activated environment first:

pip install --upgrade pip

Now, start installing libraries required by Odoo 12 for the virtual environment. Please make sure you have finished cloning Odoo 12 source code.

pip install -r /opt/odoo/odoo12/requirements.txt

Start Odoo 12

Now, we can start Odoo 12 in the virtual environment by running the following command that connects PostgreSQL on port 5432 and offers HTTP port 8089 for the client to access:

/opt/odoo/odoo12/odoo-bin --db_port=5432 --http-port=8089

You should see the output as below in the terminal:

Run Odoo 12 with PostgreSQL 10 From Command Line Interface

Now, you can open your browser and input the address like http://your_id:8089 to see the Odoo 12 Database Creator User Interface as below:

Now, you can input database name, email, etc then hit the button Create database to initilize your first Odoo 12 database.

Stop Odoo 12 and Exit

To stop the Odoo 12, just get back to the terminal and hit Ctrl+C twice.

Now, let’s get ready for the next steps to install Odoo 12 with Python 3.8 by running commands below.

Deactivate Virtual Environment

deactivate

Get back to the previous unix user account:

exit

Install Odoo 12 with Python 3.8 and PostgreSQL 12

Installing Odoo 12 with Python 3.8 is similar to the Install Odoo 12 with Python 3.7.

Create parent folder for Python 3.8 virtual environment for Odoo12

sudo mkdir -p /python-venv/3.8/odoo12
sudo chown -hR odoo12_38:odoo /python-venv/3.8/odoo12

Switch to the user odoo12_38:

sudo su - odoo12_38 -s /bin/bash

Create Python 3.8 virtual environment for Odoo 12:

python3.8 -m venv /python-venv/3.8/odoo12

Activate the virtual environment:

source /python-venv/3.8/odoo12/bin/activate

Upgrade pip

pip install --upgrade pip

Install Odoo 12’s required libraries:

pip install -r /opt/odoo/odoo12/requirements.txt

Start Odoo 12 that connects PostgreSQL 12:

/opt/odoo/odoo12/odoo-bin --db_port=5433 --http-port=8099

After verifying that the Odoo 12 worked properly, exit:

deactivate

exit

Step 6 – Run Odoo 12 as service / daemon

In this section, I will guide you on how to create startup services for your newly installed Odoo 12 instances so that they will be running as service and started every time the server is started.

Odoo 12 Python 3.7 Daemon

Create Odoo 12 Configuration File

Configuration file is the file that stores configuration directives that let Odoo know how to run (e.g. addons path, database port, etc).

In this section, I will create a configuration file named odoo12_37.conf and store it in /home/odoo12_37. I will use nano editor to create the file:

sudo nano /home/odoo12_37/odoo12_37.conf

Now, copy and pasted the following in your nano editor UI:

[options]
addons_path = /opt/odoo/odoo12/odoo/addons,/opt/odoo/odoo12/addons
admin_passwd = admin # please change this master password
csv_internal_sep = ,
data_dir = /home/odoo12_37/.local/share/Odoo
db_host = False
db_maxconn = 64
db_name = False
db_password = False
db_port = 5432
db_sslmode = prefer
db_template = template0
db_user = False
dbfilter =
demo = {}
email_from = False
geoip_database = /usr/share/GeoIP/GeoLite2-City.mmdb
http_enable = True
http_interface =
http_port = 8089
import_partial =
limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_request = 8192
limit_time_cpu = 60
limit_time_real = 120
limit_time_real_cron = -1
list_db = True
log_db = False
log_db_level = warning
log_handler = :INFO
log_level = info
logfile = None
logrotate = False
longpolling_port = 8090
max_cron_threads = 2
osv_memory_age_limit = 1.0
osv_memory_count_limit = False
pg_path = None
pidfile = None
proxy_mode = False
reportgz = False
server_wide_modules = base,web
smtp_password = False
smtp_port = 25
smtp_server = localhost
smtp_ssl = False
smtp_user = False
syslog = False
test_enable = False
test_file = False
test_tags = None
translate_modules = ['all']
unaccent = False
without_demo = False
workers = 0

Now, save the file and exit by hitting Ctrl+X then input y and hit Enter button.

To allow odoo12_37 to access the configration file:

sudo chown odoo12_37:root /home/odoo12_37/odoo12_37.conf

Create Unit Service file

sudo nano /lib/systemd/system/odoo12_37.service

Now, copy and pasted the following in your nano editor UI

[Unit]
Description=Odoo12_37
After=network.target postgresql.service

[Service]
Type=simple
PermissionsStartOnly=true
User=odoo12_37
Group=odoo
SyslogIdentifier=odoo12_37
PIDFile=/run/odoo12_37/odoo12_37.pid
ExecStartPre=/usr/bin/install -d -m755 -o odoo12_37 -g odoo /run/odoo12_37
ExecStart=/python-venv/3.7/odoo12/bin/python /opt/odoo/odoo12/odoo-bin -c /home/odoo12_37/odoo12_37.conf --pid=/run/odoo12_37/odoo12_37.pid
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID

[Install]
Alias=odoo12_37.service
WantedBy=multi-user.target

Now, save the file and exit by hitting Ctrl+X then input y and hit Enter button.

Run the following command to notify systemd that a new unit file exists:

sudo systemctl daemon-reload

Now, enable the service and ask it to run on boot:

sudo systemctl enable --now odoo12_37

Now, start your Odoo 12 using systemd:

sudo systemctl start odoo12_37

Now, let’s open your web browser and input the address https://your_ip:8089 to see the Odoo 12 Database Creation User Interface.

To stop it, just run:

sudo systemctl stop odoo12_37

Odoo 12 Python 3.8 Daemon

Create Odoo 12 Configuration File

Configuration file is the file that stores configuration directives that let Odoo know how to run (e.g. addons path, database port, etc).

In this section, I will create a configuration file named odoo12_38.conf and store it in /home/odoo12_38. I will use nano editor to create the file:

sudo nano /home/odoo12_38/odoo12_38.conf

Now, copy and pasted the following in your nano editor UI:

[options]
