How to Install Odoo 14 on Ubuntu 20.04

Odoo is a suite of open-source business applications. It consists of CRM, eCommerce, inventory, point of sale, project management, and more. These applications are fully integrated and accessed through a common web interface. With Odoo you can integrate your apps and make business life easier.

There are two editions of Oddo - the Community and Enterprise version. The Community edition is free for everyone.

Odoo has few installation options such as from the APT repository, using docker, or installing in a virtual environment.

In this tutorial, we explain how to install Odoo 14 CE on Ubuntu 20.04 inside a Python virtual environment. Hosted Odoo on Nginx as SSL Termination Proxy with Let's Encrypt certificate.

Prerequisites

A Ubuntu 20.04 instance with minimum 2 GB RAM
For database management Odoo require PostgreSQL
A non-root user with sudo priviledge

Step 1. Installing Dependencies

First, update your system.

sudo apt update
sudo apt upgrade

The following command will install all Odoo dependencies.

sudo apt install git python3-pip build-essential wget python3-dev python3-venv python3-wheel libfreetype6-dev libxml2-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools node-less libjpeg-dev zlib1g-dev libpq-dev libxslt1-dev libldap2-dev libtiff5-dev libjpeg8-dev libopenjp2-7-dev liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev libxcb1-dev

Step 2. Creating a System User

For running Odoo we'll need to create a new system user and group with a home directory under the path /opt/odoo14 that will need to be able to run an Odoo service.

sudo useradd -m -d /opt/odoo14 -U -r -s /bin/bash odoo14

Step 3. Install and Configure PostgreSQL

First, install PostgreSQL using apt.

sudo apt install postgresql

Once PostgreSQL installation is completed, then we'll need to create a PostgreSQL user. Keep in mind that we are going to use the same name as we previously created a system user. That is oddo14.

sudo su - postgres -c "createuser -s odoo14"

Step 4. Installing wkhtmltopdf

wkhtmltopdf - is an open-source command-line tool that supports the rendering of HTML pages into PDF and other similar formats.

To able print PDF formats and reports in Odoo, will need to install the wkhtmltopdf package.

First, download the package using wget command.

sudo wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.bionic_amd64.deb

Once the download is completed, install wkhtmltopdf using the apt command:

sudo apt install ./wkhtmltox_0.12.6-1.bionic_amd64.deb

Step 5. Install and Configure Odoo 14

As we mentioned in the introduction, we'll install Odoo from the source as an isolated Python virtual environment.

First, change a user to odoo14 with the following command.

sudo su - odoo14

To clone the Odoo 14 official source code from GitHub, type:

git clone https://www.github.com/odoo/odoo --depth 1 --branch 14.0 /opt/odoo14/odoo

Then change directory to /opt/odoo14

cd /opt/odoo14

From there, create a new Python virtual environment for Odoo with the following command.

python3 -m venv odoo-venv

And activate the virtual environment.

source odoo-venv/bin/activate

After activating the virtual environment, install all required Python modules with pip3.

(odoo-venv) $ pip3 install wheel

And install

(odoo-venv) $ pip3 install -r odoo/requirements.txt

This can take some time, when it's done, deactivate the environment with the following command.

(odoo-venv) $ deactivate

Create a new directory in /opt/odoo14 path, that will contain the 3rd party addons that we're gonna include in the configuration.

mkdir /opt/odoo14/odoo-custom-addons

We'll add this directory to the addons_path parameter. This parameter will define a list of directories where Odoo will search for modules.

Next, exit from odoo user, and switch back to your sudo user.

exit

Create a configuration file:

sudo nano /etc/odoo14.conf

And past the following contents in the file:

[options]
 ; This is the password that allows database operations:
 admin_passwd = put_your_secure_password
 db_host = False
 db_port = False
 db_user = odoo14
 db_password = False
 addons_path = /opt/odoo14/odoo/addons,/opt/odoo14/odoo-custom-addons

Step 6. Create a Systemd Unit File

Create a service unit file called odoo14.service in the directory /etc/systemd/system/.

sudo nano /etc/systemd/system/odoo14.service

And past the following configuration:

[Unit] 
Description=Odoo14
Requires=postgresql.service 
After=network.target postgresql.service 

[Service] 
Type=simple 
SyslogIdentifier=odoo14 
PermissionsStartOnly=true 
User=odoo14 
Group=odoo14 
ExecStart=/opt/odoo14/odoo-venv/bin/python3 /opt/odoo14/odoo/odoo-bin -c /etc/odoo14.conf 
StandardOutput=journal+console 

[Install] 
WantedBy=multi-user.target

Tell systemd that a new unit file has been created.

sudo systemctl daemon-reload

And start the Odoo service and enable it to start on boot with the following command:

sudo systemctl enable --now odoo14

Output:

Created symlink /etc/systemd/system/multi-user.target.wants/odoo14.service → /etc/systemd/system/odoo14.service.

Verify service status:

sudo systemctl status odoo14

The output that showing the Odoo service is up and running:

Open your browser and type: http://<your_domain_or_IP_address>:8069

Put Master Password that you previously defined in configuration path /etc/odoo14.conf, and enter other credentials to Create a database.

After successfully created database will be redirected to the Odoo14 Dashboard.

Step 7. Configuring Nginx as SSL Termination Proxy (Optional)

If you want to make Odoo more secure for your environment, we can set Nginx as an SSL termination proxy that will serve the traffic over HTTPS, instead of the default Odoo web serving traffic over HTTP.

SSL Termination Proxy presents a proxy server that will handle the SSL encryption. In our case termination proxy is Nginx, he will process and decrypt incoming TLS connections (HTTPS) and pass on the unencrypted request to the Odoo service.

Prerequisites

Domain name that point to your public server IP
For this article we'll use example.conf
Nginx installed
Let's Encypt SSL certificate

Be sure to check you have working Let's Encrypt or some other SSL certificate set up correctly.

To install the Let's Encrypt SSL certificate we first need to install certbot:

# apt install certbot
# apt install python3-certbot-nginx

Next, run the following command with example.com domain name and fill in the required information:

# certbot --nginx -d example.com -d www.example.com

Output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx
Enter email address (used for urgent renewal and security notices) (Enter 'c' to
cancel):

1. Create or edit the domain server block

sudo nano /etc/nginx/sites-enabled/example.com.conf

And past the following configuration:

# Odoo servers
 upstream odoo {
  server 127.0.0.1:8069;
 }

 upstream odoochat {
  server 127.0.0.1:8072;
 }

 # HTTP -> HTTPS
 server {
     listen 80;
     server_name www.example.com example.com;
     return 301 https://example.com$request_uri;
 }

 # WWW -> NON WWW
 server {
     listen 443 ssl http2;
     server_name www.example.com;

     ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
     ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
     ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;

     return 301 https://example.com$request_uri;
 }

 server {
     listen 443 ssl http2;
     server_name 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;

# SSL parameters
     ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
     ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
     ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;

# 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;
}

NOTE: Don’t forget to replace example.com with your Odoo domain and set the correct path to the SSL certificate files.

2. Restart the Nginx service

sudo systemctl restart nginx

After restarting the Nginx service, we'll need to tell Odoo to use this configured proxy.

3. Open the configuration file.

sudo nano /etc/odoo14.conf

4. And add the following line.

proxy_mode = True

5. Finally, restart the Odoo service.

sudo systemctl restart odoo14

If you followed all steps, will be able to access your Odoo web instance at https://example.com
