Odoo ERP is used in many industries, including Manufacturing companies, Distribution companies, R&D companies, Service companies, Accounting firms, and more.
This post will show you how to install Odoo 15 ERP on Ubuntu 22.04.
Prerequisites
- A server running Ubuntu 22.04.
- A valid domain name is pointed with your server IP.
- A root password is configured on the server.
Getting Started
Before starting, updating all system packages to the latest version is recommended. You can update them by running the following command:
apt update -y
Once your system is updated, install the Python and other dependencies using the following command:
apt install python3-pip wget python3-dev python3-venv python3-wheel libxml2-dev libpq-dev libjpeg8-dev liblcms2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential git libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libblas-dev libatlas-base-dev -y
Once all Python dependencies are installed, install the wkhtmltopdf package with the following command:
apt-get install wkhtmltopdf -y
Next, verify the version of wkhtmltopdf using the following command:
wkhtmltopdf --version
You should see the following output:
wkhtmltopdf 0.12.6
Odoo uses PostgreSQL as a database backend so you will also need to install it on your server. You can install it using the following command:
apt install postgresql -y
Once the PostgreSQL is installed, create a PostgreSQL user for Odoo using the following command:
su - postgres -c "createuser -s odoo15"
Install and Configure Odoo 15
Before starting, it is good idea to create a dedicated user to run the Odoo instance. You can create a new user named odoo15 using the following command:
useradd -m -d /opt/odoo15 -U -r -s /bin/bash odoo15
Once the user is created, switch the user to Odoo15 and download the latest version of Odoo with the following command:
su - odoo15
git clone https://www.github.com/odoo/odoo --depth 1 --branch 15.0 /opt/odoo15/odoo
Next, change the directory to Odoo15 and create a Python virtual environment using the following command:
cd /opt/odoo15
python3 -m venv odoo15-venv
Next, activate the virtual environment using the following command:
source odoo15-venv/bin/activate
Next, install the wheel package with the following command:
pip3 install wheel
Next, edit the requirements.txt file and update some requirements:
nano /opt/odoo15/odoo/requirements.txt
Change the following lines:
gevent>=20.9.0 ; python_version >= '3.8' greenlet>=0.4.17 ; python_version > '3.7'
Save and close the file then install all the dependencies using the following command:
pip3 install -r odoo/requirements.txt
Once all the dependencies are installed, deactivate from the virtual environment using the following command:
deactivate
Next, create a directory to store Odoo addons and exit from the Odoo user with the following command:
mkdir /opt/odoo15/custom-addons
exit
Next, edit the Odoo configuration file with the following command:
nano /etc/odoo15.conf
Add the following lines:
[options] ; This is the password that allows database operations: admin_passwd = adminpassword db_host = False db_port = False db_user = odoo15 db_password = False xmlrpc_port = 8069 logfile = /var/log/odoo15/odoo.log addons_path = /opt/odoo15/odoo/addons,/opt/odoo15/custom-addons
Save and close the file then create a directory to store the Odoo log and change the ownership:
mkdir /var/log/odoo15
chown odoo15:root /var/log/odoo15
Create a Systemd Service File for Odoo 15
Next, you will need to create a systemd service file to manage the Odoo service. You can create it with the following command:
nano /etc/systemd/system/odoo15.service
Add the following lines:
[Unit] Description=Odoo15 Requires=postgresql.service After=network.target postgresql.service [Service] Type=simple SyslogIdentifier=odoo15 PermissionsStartOnly=true User=odoo15 Group=odoo15 ExecStart=/opt/odoo15/odoo15-venv/bin/python3 /opt/odoo15/odoo/odoo-bin -c /etc/odoo15.conf StandardOutput=journal console [Install] WantedBy=multi-user.target
Save and close the file then reload the systemd daemon with the following command:
systemctl daemon-reload
Next, start the Odoo service and enable it to start at system reboot:
systemctl enable --now odoo15
You can now check the status of the Odoo service using the following command:
systemctl status odoo15
You should see the active status of the Odoo instance in the following output:
? odoo15.service - Odoo15
Loaded: loaded (/etc/systemd/system/odoo15.service; enabled; vendor preset: enabled)

Configure Nginx as a Reverse Proxy for Odoo
It is a good idea to configure Nginx as a reverse proxy for Odoo. First, install the Nginx package using the following command:
apt-get install nginx -y
Once the Nginx is installed, create an Nginx virtual host configuration file for Odoo:
nano /etc/nginx/conf.d/odoo15.conf
Add the following lines:
# Odoo servers
upstream odoo {
server 127.0.0.1:8069;
}
upstream odoochat {
server 127.0.0.1:8072;
}
server {
listen 80;
server_name odoo15.example.com;
proxy_read_timeout 720s;
proxy_connect_timeout 720s;
proxy_send_timeout 720s;
# Proxy headers
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
# log files
access_log /var/log/nginx/odoo.access.log;
error_log /var/log/nginx/odoo.error.log;
# Handle longpoll requests
location /longpolling {
proxy_pass http://odoochat;
}
# Handle / requests
location / {
proxy_redirect off;
proxy_pass http://odoo;
}
# Cache static files
location ~* /web/static/ {
proxy_cache_valid 200 90m;
proxy_buffering on;
expires 864000;
proxy_pass http://odoo;
}
# Gzip
gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
gzip on;
}
Save and close the file then verify the Nginx for any syntax configuration error:
nginx -t
You should see the following output:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
Finally, restart the Nginx service to apply the changes:
systemctl restart nginx
Next, edit the Odoo configuration file and enable the proxy setting:
nano /etc/odoo15.conf
Add the following line:
proxy_mode = True
Save and close the file then restart the Odoo service to apply the changes:
systemctl restart odoo15
You can now verify the Nginx status using the following command:
systemctl status nginx
You will get the following output:
? nginx.service - A high performance web server and a reverse proxy server
