In this tutorial, we will explain how to install multiple Odoo instances on a single Ubuntu 16.04 VPS using a python virtual environment. This guide should work on other Linux VPS systems as well but was tested and written for an Ubuntu 16.04 VPS.
Log in to your VPS via SSH
ssh user@vps_IP
Update the system and install all necessary packages
sudo apt-get update && apt-get -y upgrade
sudo apt-get install git wkhtmltopdf python-pip python-dev
python-virtualenv libevent-dev gcc libjpeg-dev libxml2-dev
libssl-dev libsasl2-dev node-less libldap2-dev libxslt-dev
Install PostgreSQL
Installing PostgreSQL with apt is quick and easy:
apt install postgresql-9.5 postgresql-server-dev-9.5 systemctl enable postgresql.service systemctl start postgresql.service
Create Odoo users
We will install two Odoo instances, Odoo version 10 and Odoo version 9. To create system users for both instances run:
sudo adduser --system --group odoo10 --home /opt/odoo10 sudo adduser --system --group odoo9 --home /opt/odoo9
Create PostgreSQL database users, odoo10 and odoo9:
su - postgres -c "createuser --createdb --username postgres --no-createrole --no-superuser --no-password odoo10" su - postgres -c "createuser --createdb --username postgres --no-createrole --no-superuser --no-password odoo9"
Install Odoo
First, we will install Odoo version 10. To switch to user odoo10 run:
sudo su - odoo10 -s /bin/bash
Clone the Odoo 10.0 branch from github:
git clone https://www.github.com/odoo/odoo --depth 1 --branch 10.0 --single-branch /opt/odoo10
Create python virtual environment and install all requirements:
cd /opt/odoo10 virtualenv ./venv source ./venv/bin/activate pip install -r requirements.txt
Switch back your user:
exit
To install Odoo version 9, switch to user odoo9:
sudo su - odoo9 -s /bin/bash
Clone the Odoo 9.0 branch from github:
git clone https://www.github.com/odoo/odoo --depth 1 --branch 9.0 --single-branch /opt/odoo9
Create python virtual environment and install all requirements:
cd /opt/odoo9 virtualenv ./venv source ./venv/bin/activate pip install -r requirements.txt
Switch back your user:
exit
Configure Odoo
We will configure Odoo 10 to listen on port 8010 and Odoo 9 to port 8009 and set the master admin password. You can also set the ports numbers according to your liking.
>sudo nano /etc/odoo10.conf
[options] admin_passwd = your_strong_admin_password db_host = False db_port = False db_user = odoo10 db_password = False addons_path = /opt/odoo10/addons logfile = /var/log/odoo10.log xmlrpc_port = 8010
sudo nano /etc/odoo9.conf
[options] admin_passwd = your_strong_admin_password db_host = False db_port = False db_user = odoo9 db_password = False addons_path = /opt/odoo9/addons logfile = /var/log/odoo9.log xmlrpc_port = 8009
Create SystemD scripts:
sudo nano /lib/systemd/system/odoo10.service
[Unit] Description=Odoo 10 Requires=postgresql.service After=postgresql.service [Service] Type=simple PermissionsStartOnly=true User=odoo10 Group=odoo10 SyslogIdentifier=odoo10 ExecStart=/opt/odoo10/venv/bin/python2 /opt/odoo10/odoo-bin -c /etc/odoo10.conf [Install] WantedBy=multi-user.target
sudo nano /lib/systemd/system/odoo9.service
[Unit] Description=Odoo 10 Requires=postgresql.service After=postgresql.service [Service] Type=simple PermissionsStartOnly=true User=odoo9 Group=odoo9 SyslogIdentifier=odoo9 ExecStart=/opt/odoo9/venv/bin/python2 /opt/odoo9/openerp-server -c /etc/odoo9.conf [Install] WantedBy=multi-user.target
Final steps
Enable both Odoo instances to start on boot:
sudo systemctl enable odoo10.service sudo systemctl enable odoo9.service
To start both Odoo 10 and Odoo 9 instances, run:
sudo systemctl start odoo10.service sudo systemctl start odoo9.service
You can now access your Odoo 10 installation at http://your_ip_address:8010 and Odoo 9 installation at http://your_ip_address:8009.
That’s it. You have successfully installed both Odoo version 10 and version 9 on your Ubuntu VPS. Now open your browser, type the address of your installation and create a database and admin user.
