In this tutorial, we will show you how to install multiple instances of Odoo on a single Ubuntu 16.04 VPS using a Python virtual environment. This guide should work on other Linux VPS systems, just as well, but was tested and written for an Ubuntu 16.04 VPS.

Login to your VPS via SSH

                      ssh [email protected]_IP
                    

Update your system and install all required 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
                    

Installing PostgreSQL

Installing PostgreSQL with apt:

                      apt install postgresql-9.5 postgresql-server-dev-9.5
systemctl enable postgresql.service
systemctl start postgresql.service
                    

Creating Odoo Users

We will install two instances of Odoo, Odoo version 10 and Odoo version 9. To create system users for both:

                      sudo adduser --system --group odoo10 --home /opt/odoo10
sudo adduser --system --group odoo9 --home /opt/odoo9
                    

Create a PostgreSQL user database, 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:

                      sudo su - odoo10 -s /bin/bash
                    

Cloning Odoo 10 from Github:

                      git clone https://www.github.com/odoo/odoo --depth 1 --branch 10.0 --single-branch /opt/odoo10
                    

Create a python virtual environment and install all requirements:

                      cd /opt/odoo10
virtualenv ./venv
source ./venv/bin/activate
pip install -r requirements.txt
                    

Switch your user:

                      exit
                    

To install Odoo version 9, switch to user odoo9:

                      sudo su - odoo9 -s /bin/bash
                    

Cloning Odoo 9.0 from Github:

                      git clone https://www.github.com/odoo/odoo --depth 1 --branch 9.0 --single-branch /opt/odoo9
                    

Create a python virtual environment and install all requirements:

                      cd /opt/odoo9
virtualenv ./venv
source ./venv/bin/activate
pip install -r requirements.txt
                    

Switch to your user:

                      exit
                    

Setting up Odoo

We will configure Odoo 10 to listen on port 8010 and Odoo 9 to port 8009 and set a master admin password. You can also set the port numbers according to your wishes.

                      >sudo nano /etc/odoo10.conf
                    

                      [options]
admin_passwd = ваш_сложный_пароль
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 = ваш_сложный_пароль
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
                    

Systemd scripting:

                      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 at boot:

                      sudo systemctl enable odoo10.service
sudo systemctl enable odoo9.service
                    

To launch instances of Odoo 10 and Odoo 9, run the following command:

                      sudo systemctl start odoo10.service
sudo systemctl start odoo9.service
                    

You can now access the Odoo 10 installation at https://your_ip_address:8010  and installing Odoo 9 at https://your_ip_address:8009 …

That’s all. You have successfully installed Odoo version 10 and version 9 on your Ubuntu VPS. Now open your browser, enter the address of your installation and create a database user and administrator.
