In this guide, we will show you how to install Odoo 15 on Ubuntu 20.04.
- An Ubuntu 20.04 (we’ll be using our SSD 2 VPS plan)
- Access to the root user account (or access to an admin account with root privileges)
Log in and Update the Server:
Log in to your Ubuntu 20.04 VPS via SSH as user root (You can use a superuser account if the root is not available. Our VPSes come with root access included):
ssh root@IP_Address -p Port_number
Don’t forget to replace ‘IP_Address’ and ‘Port_number’ with the actual IP address of your server and the SSH service port. The default SSH port is 22.
Run the following commands to make sure that all installed packages on your Ubuntu 20.04 VPS are updated to their latest available versions:
apt-get update -y && apt-get upgrade -y
Install Necessary Dependencies
Next, you will need to install all necessary dependencies including, Node,js and Python in your server. Run the following command to install all the dependencies:
apt-get install python3-pip python-dev python3-dev 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
Next, install the Node.js and NPM using the following command:
apt-get install npm npm install -g less less-plugin-clean-css apt-get install node-less
Next, download and install the wkhtmltopdf package by running the following command:
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.bionic_amd64.deb dpkg -i wkhtmltox_0.12.6-1.bionic_amd64.deb apt-get install -f
Odoo uses PostgreSQL as a database backend. So you will need to install the PostgreSQL to your server. Run the following command to install the PostgreSQL server.
apt-get install postgresql -y
Once the PostgreSQL is installed, log in to PostgreSQL and create an Odoo user with the following command:
su - postgres createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo15 psql ALTER USER odoo15 WITH SUPERUSER;
Next, exit from the PostgreSQL with the following command:
Install and Configure Odoo 15
First, create an Odoo user with the following command:
useradd -m -d /opt/odoo15 -U -r -s /bin/bash odoo15
Next, switch the user to Odoo 15 and download the Odoo 15 from the Git repository:
su - odoo15 git clone https://www.github.com/odoo/odoo --depth 1 --branch 15.0 /opt/odoo15/odoo
Next, exit from the Odoo 15 user and install all required Python dependencies using the following command:
exit pip3 install -r /opt/odoo15/odoo/requirements.txt
Next, copy the Odoo 15 sample configuration file to the /etc directory:
cp /opt/odoo15/odoo/debian/odoo.conf /etc/odoo.conf
Next, edit the Odoo 15 configuration file using your favourite editor:
Change the following lines:
[options] ; This is the password that allows database operations: admin_passwd = masterpassword db_host = False db_port = False db_user = odoo15 db_password = False xmlrpc_interface = 127.0.0.1 proxy_mode = True addons_path = /opt/odoo15/odoo/addons logfile = /var/log/odoo/odoo.log
Save and close the file then set proper ownership to the Odoo 15 configuration file.
chown odoo15: /etc/odoo.conf
Next, create a log directory for Odoo 15 and set proper ownership:
mkdir /var/log/odoo chown odoo15:root /var/log/odoo
Create a Systemd Service File for Odoo 15
Next, you will need to create a systemd service file to manage the Odoo 15 service. You can create it using the following command:
Add the following lines:
[Unit] Description=Odoo Documentation=http://www.odoo.com [Service] Type=simple User=odoo15 ExecStart=/opt/odoo15/odoo/odoo-bin -c /etc/odoo.conf [Install] WantedBy=default.target
Save and close the file then reload the systemd daemon to apply the changes:
Next, start and enable the Odoo 15 service:
systemctl start odoo15 systemctl enable odoo15
To verify the status of the Odoo 15 service, run the following command:
systemctl status odoo15
● odoo15.service - Odoo Loaded: loaded (/etc/systemd/system/odoo15.service; disabled; vendor preset: enabled) Active: active (running) since Mon 2021-10-11 10:35:36 UTC; 5s ago Docs: http://www.odoo.com Main PID: 21021 (python3) Tasks: 4 (limit: 4691) Memory: 66.9M CGroup: /system.slice/odoo15.service └─21021 python3 /opt/odoo15/odoo/odoo-bin -c /etc/odoo.conf Oct 11 10:35:36 ubuntu2004 systemd: Started Odoo.
Configure Nginx as a Reverse Proxy for Odoo 15
It is always 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
Next, create an Nginx virtual host configuration file:
Add the following configuration:
Save and close the file then restart the Nginx to apply the changes:
systemctl restart nginx
Access the Odoo 15 Instance
Now when you know that the fresh Odoo installation is active and running on the server, you can access it using the URL http://odoo15.example.com. If the installation has been successfully completed, you will be able to see the Odoo screen as shown below and create your first database:
From here, you simply enter your master password and fill out the fields with the information that you need for your use case. Then, click on the Create database button. You should see the Odoo15 dashboard:
Of course, you don’t have to install Odoo 15 on Ubuntu 20.04 if you use one of our Odoo VPS Hosting services, in which case you can simply ask our expert Linux admins to install and configure Odoo 15 on Ubuntu 20.04 for you. They are available 24×7 and will take care of your request immediately.
