Prerequisites

• You need to have Debian 11 server up and running
• Have PostgreSQL installed
• Have a non-root user with sudo privileges if you are not root

We have two versions of Odoo, the community version which is free and open-source, and the enterprise version available for enterprise customers only. We are going to install the free version i.e the community version.

Install Odoo 15 on Debian 11

1. Update system repositories

The first thing to do is to update your system repositories in order to make them up to date. Use the following command to do so.

sudo apt update && apt upgrade -y 

2. Install the PostgreSQL database

Odoo needs the PostgreSQL server to run smoothly. So we need to install it onto our system with the following command.

sudo apt install -y postgresql

Sample output from the installation of Postgresql

#output
Success. You can now start the database server using:

    pg_ctlcluster 12 main start

Ver Cluster Port Status Owner    Data directory              Log file
12  main    5432 down   postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log
update-alternatives: using /usr/share/postgresql/12/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode
Setting up sysstat (12.2.0-2ubuntu0.1) ...

Creating config file /etc/default/sysstat with new version
update-alternatives: using /usr/bin/sar.sysstat to provide /usr/bin/sar (sar) in auto mode
Created symlink /etc/systemd/system/multi-user.target.wants/sysstat.service → /lib/systemd/system/sysstat.service.
Setting up postgresql (12+214ubuntu0.1) ...
Processing triggers for systemd (245.4-4ubuntu3.15) ...
Processing triggers for man-db (2.9.1-1) ...
Processing triggers for libc-bin (2.31-0ubuntu9.7) ...

Now that we have installed PostgreSQL, we need to start the server cluster with the following command.

pg_ctlcluster 12 main start

Then you can check the cluster if it is up and running with the following command.

sudo systemctl status postgresql

3. Add Odoo package repository for Debian 11

Odoo provides a package repository for Ubuntu that will allow us to add nightly keys to our system repositories hence allowing us to install Odoo with ease.

So the first thing is to add keys to our system with the following command.

wget -O - https://nightly.odoo.com/odoo.key | apt-key add -

Then after that is complete, add Odoo nightly 15 to our sources.listd.d which will in turn allows us to make some required configuring to Odoo once installed.

echo "deb http://nightly.odoo.com/15.0/nightly/deb/ ./" >> /etc/apt/sources.list.d/odoo.list

Lastly, we need to run system-wide updates again and then install Odoo.

sudo apt update 

4. Install Odoo 15 on Ubuntu 20.04

To install Odoo run the following command.

sudo apt install odoo -y

Now we can check the status of Odoo to confirm if it is running or not.

systemctl status odoo
● odoo.service - Odoo Open Source ERP and CRM
     Loaded: loaded (/lib/systemd/system/odoo.service; enabled; vendor preset: enabled)

             └─22778 /usr/bin/python3 /usr/bin/odoo --config /etc/odoo/odoo.conf --logfile /var/log/odoo/odoo-server.log

Apr 13 05:40:30 debian systemd[1]: Started Odoo Open Source ERP and CRM.

We need to enable Odoo to start automatically every time we boot up.

systemctl enable odoo --now
Synchronizing state of odoo.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable odoo

Odoo listens on TCP port 8069. We can confirm that with the following command.

ss -tunelp | grep 8069
tcp   LISTEN 0      128          0.0.0.0:8069      0.0.0.0:*    users:(("odoo",pid=22778,fd=5)) uid:109 ino:38497 sk:5 cgroup:/system.slice/odoo.service <->       

To login into Odoo use the following on your browser.

http://<IP-address>:8069

When you login to Odoo for the first time you will find that the connection is not secure. What we will do is install an SSL certificate in order to make our connection secure.

Conclusion

We have successfully installed Odoo on Debian 11, what remains is the SSL certificate for production-ready sites. I will tackle that next.
