Install and Deploy Odoo 14 from source on DigitalOcean

Deploy Odoo 14 on Ubuntu 20.04 with DigitalOcean
Table of Contents

In this tutorial, we will deploy a production-ready Odoo 14 instance. Install it from GitHub source on a brand new DigitalOcean Droplet Ubuntu 20.04 (LTS) x64. What we will do:

  • Going through DigitalOcean registration
  • Installing all the Ubuntu 20.4 requirements necessary to install Odoo from the source
  • Using Pyenv to prepare our server for multiple python versions and virtualenvs in case you want to host other versions of Odoo
  • Creating odoo user and making Odoo run as a service
  • Install Let's Encrypt SSL Certificate
  • Making Odoo multiprocess and using Nginx as a reverse proxy
  • Basic security with ufw

DigitalOcean offers you 100€ credit to use in 6 months since you can create machines and destroy them quickly it's a great place to experiment with Odoo installs or to choose it as your production server!

Creating a DigitalOcean account

First of all, go to DigitalOcean and create an account using the link

DigitalOcean Register
DigitalOcean Register

Create your credentials, validate your email and follow the steps until you arrive on that page

DigitalOcean Register Choose Control panel
DigitalOcean Register Choose Control panel

Here it can get a bit confusing because most of the links direct you to the DigitalOcean platform but we want the regular dashboard so click on Explore our control panel

When on the Control Panel click on Get Started with a Droplet or Create / Droplet to arrive on this screen

Create Ubuntu Droplet
Create Ubuntu Droplet

Choose Ubuntu 20.04 and choose the right machine based on your needs. Remember that you are only billed for the time that the machine is up so you can choose a good machine and destroy it later. Choose at least 2 CPUs or everything will feel very slow.

Scrolling down you will see a space to add your ssh-key

Adding the SSH KEY
Adding the SSH KEY

Adding SSH Key

If you don't have an SSH Key yet you have to generate it with the command. You probably already have an id_rsa.pub file in your .ssh folder. For this example, we will create a new SSH key that will be used to connect to our DigitalOcean Droplets. Feel free to skip that part or read it to create your first key or handle multiple ssh keys.

ssh-keygen -C "[email protected]"

When prompted for the name of the file we choose that


Show the content of the newly generated key:

cat ~/.ssh/id_rsa_codingdodo.pub

On DigitalOcean, click on New SSH Key and copy/paste the content printed out. Scroll down more and click on Create Droplet. It will take a minute then your Droplet will be ready

Droplet is Ready
Droplet is Ready

Copy the IP Address, we will add it to our SSH config file to make things easier for us. If you handle multiple SSH Keys this is a nice way to handle with which SSH Key you connect to each server.

vim ~/.ssh/config

Add this section with your IP address and the name of the public key you created.

 Host testingdodo
   User root
   IdentityFile ~/.ssh/id_rsa_codingdodo
   IdentitiesOnly yes

We name our Host testingdodo so in our shell, we can type this shortcut to ssh into the machine.

ssh testingdodo

And answer yes to the security prompt, and you will be logged in

Welcome to Ubuntu 20.04.1 LTS (GNU/Linux 5.4.0-51-generic x86_64)



Ubuntu 20.4 Prerequisites

On a new machine, I have the habit of updating the packages first before beginning installing everything. We start by updating our packages

apt update

Then we upgrade the installed packages.

apt upgrade -y

If you run into a message saying that the sshd_config has been modified:

Choose to keep the local version currently installed of sshd_config file
Choose to keep the local version currently installed of sshd_config file

Choose to keep the local version currently installed.

Installing PostgreSQL

apt install postgresql postgresql-contrib -y

We will later create a Unix user named Odoo, so we will create a PostgreSQL user with the same name. If you would prefer a different name, remember to keep that consistency to make things easier when you come back later to your environment.

su - postgres
createuser --interactive -P odoo

With the --interactive flag, PostgreSQL will ask us for a password and the privileges that will be given to our odoo PostgreSQL user.

Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) n

Next, we will already create that database that will hold our Odoo 14 instance. In this example, it's gonna be named coding_dodo.

createdb -O odoo codingdodo_demo

The -O flag represents the owner of the database, we choose odoo because it's the name of the PostgreSQL user we created just before


Wkhtmltopdf is used by Odoo to generate documents and is a necessary evil. We will pull the deb of version 0.12.6-2 from Github and install it

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

Python dev dependencies, git, Node, and other requirements

apt install -y build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev python-openssl git libpq-dev libsasl2-dev libldap2-dev ccze node-less

Creating the Unix odoo user

useradd -m -U -r -s /bin/bash odoo

-r indicate that it's a system account so useradd will not create a home directory for such a user. We want a folder so we use -m
-U create a group and -s specify the shell that will be used.

Or if you don't want to have /home/odoo created to hold your odoo install and would prefer a different directory. This is an example that will create the home directory in /opt for example.

useradd -m -d /opt/odoo -U -r -s /bin/bash odoo

-d [path] indicates we want to create a home but in different place.

Preparing a good Python environment with Pyenv

Log in as the odoo user

The pyenv will be installed as the odoo system user. That user is gonna run the odoo instance as a service later.

su - odoo

Installing pyenv

curl https://pyenv.run | bash

Adding python to the path

echo -e 'if shopt -q login_shell; then' \
      '\n  export PYENV_ROOT="$HOME/.pyenv"' \
      '\n  export PATH="$PYENV_ROOT/bin:$PATH"' \
      '\n eval "$(pyenv init --path)"' \
      '\nfi' >> ~/.bashrc
echo -e 'if [ -z "$BASH_VERSION" ]; then'\
      '\n  export PYENV_ROOT="$HOME/.pyenv"'\
      '\n  export PATH="$PYENV_ROOT/bin:$PATH"'\
      '\n  eval "$(pyenv init --path)"'\
      '\nfi' >>~/.profile

Now log off and log-in again as odoo user

su - odoo

Installing python 3.9.2

pyenv install 3.9.2

Depending on the CPU power you choose, it may take some time, but in the end, you should see:

Installed Python-3.9.2 to /home/odoo/.pyenv/versions/3.9.2

As suggested by Jacob Christ in the comments, do a sanity check to see if pyenv can pickup python version in your environment by typing python --version you should see this.

odoo@ubuntu-s-4vcpu-8gb-amd-blr1-01:~$ python --version
pyenv: python: command not found

The `python' command exists in these Python versions:

Note: See 'pyenv help global' for tips on allowing both
      python2 and python3 to be found.

If you can't see the newly installed python you should check the pyenv documentation here to make it available in your path via a different method than what we did earlier.

Creating the virtualenv

pyenv virtualenv 3.9.2 odoo-14-env

Installing Odoo from GitHub source

Creating a folder for our custom addons (Optional)

mkdir /home/odoo/odoo-14-custom-addons

This is the folder you will use to store your custom addons. Be careful if you add the custom addon patch to the --addons-path command-line argument and there are no valid addons inside, it will not work.

To make it work we will clone our own module inside that folder

cd /home/odoo/odoo-14-custom-addons
git clone https://github.com/Coding-Dodo/web_widget_markdown.git
cd ~/

Pulling Odoo 14 and activating the virtualenv

We will pull Odoo version 14 with the -b flag for the branch and put it in a folder named odoo-14

git clone -b 14.0 --single-branch --depth 1 https://github.com/odoo/odoo.git odoo-14

Since we created our virtualenv called odoo-14-env, we will "park" it in the odoo-14 folder we just created. With that every time we cd into this folder it will activate our virtualenv.

cd odoo-14
pyenv local odoo-14-env

The prompt should change and you should see (odoo-14-env) odoo@ubuntu-s-1vcpu-1gb-intel-nyc1-01

Do another sanity check by typing python --version you should now have that output:

odoo@ubuntu-s-4vcpu-8gb-amd-blr1-01:~/odoo-14$ python --version
Python 3.9.2

Installing python dependencies

pip install --upgrade pip
pip install setuptools wheel
pip install -r requirements.txt -e .

If you see any error please refer to the part "Python dev dependencies, git, Node and other requirements" and make sure you installed everything.

Launching Odoo for the first time to test and generate a config file

We will test launch Odoo with some command-line arguments that will be saved in our Odoo configuration file

./odoo-bin --database=codingdodo_demo --db_user=odoo --db_password=codingdodo -i base --without-demo=all --save -c /home/odoo/.odoorc_codingdodo_demo --stop-after-init
If you chose to create a custom addons folder and it's not empty. The command will be
./odoo-bin --database=codingdodo_demo --db_user=odoo --db_password=codingdodo -i base --addons-path="/home/odoo/odoo-14/addons,/home/odoo/odoo-14-custom-addons" --without-demo=all --save -c /home/odoo/.odoorc_codingdodo_demo --stop-after-init

We directly typed the db name, user, and password and initialized it with the iflag.
--without-demo=all is used because we are installing a production-ready environment. If you want demo data, omit that flag.
With the -c flag we told odoo where the config file will be  /home/odoo/.odoorc_codingdodo_demo
The --save flag is used to save everything we just typed into the newly created config file.

(Optional) Updating config file admin_passwd with a random strong password:

If you want to quickly change the password inside your config file

sed -i "s/\badmin\b/$(openssl rand -base64 32 | awk '{print $1}')/g" /home/odoo/.odoorc_codingdodo_demo

This will replace the line admin_passwd = admin with a new password randomly generated via OpenSSL.

To check what the new admin_passwd is:

cat /home/odoo/.odoorc_codingdodo_demo | grep admin_passwd

admin_passwd = C4Yiyiez4CHMl5tsmRHVZHflfnITd3nF5oXh8l3ZPc8=

Keep it somewhere safe because after running the instance it will be hashed.

Create the logs directory

We want our log files to be inside /var/log/odoo/ so we create that folder and give odoo user access to it.

mkdir /var/log/odoo
touch /var/log/odoo/odoo-14.log
chown odoo: /var/log/odoo
chown -R odoo: /var/log/odoo/*

log back as odoo and edit the config file

su - odoo
vim /home/odoo/.odoorc_codingdodo_demo

Modify the config file to reflect that change

logfile = /var/log/odoo/odoo-14.log

Odoo as service

Log out of odoo user and create a service file

vim /etc/systemd/system/odoo-14.service

You don't have to use vim to edit your file, but if you follow exactly the commands, to go into Insert mode press I, then copy that content via Ctrl + V (or Cmd + V)

After=network.target postgresql.service

ExecStart=/home/odoo/.pyenv/versions/odoo-14-env/bin/python /home/odoo/odoo-14/odoo-bin -c /home/odoo/.odoorc_codingdodo_demo


If you are using vim press :wq to save and exit the file.

Now we Reload the service.

systemctl daemon-reload
systemctl enable --now odoo-14

Check status via systemctl status odoo-14 and you should see

systemctl status odoo-14
● odoo-14.service - Odoo14

Install Nginx and add SSL with Let's Encrypt

Installing Nginx

apt install nginx -y

Let's Encrypt with Certbot

Certbot will be used to install our first certificate and to renew it every months

apt install certbot -y

Generate a new set of 2048 bit DH parameters by typing the following command:

sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

Let's Encrypt Nginx Snippet

Let's Encrypt need to do its acme-challenge to validate our domain name and creating the certificate with certbot. If we plan to install multiple instances / different domain names pointing to this server, it is a good habit to isolate the let's encrypt acme-challenge location to its custom snippet.

mkdir -p /var/lib/letsencrypt/.well-known
chgrp www-data /var/lib/letsencrypt
chmod g+s /var/lib/letsencrypt

We create a Let's Encrypt snippet

vim /etc/nginx/snippets/letsencrypt.conf

With this content

location ^~ /.well-known/acme-challenge/ {
  allow all;
  root /var/lib/letsencrypt/;
  default_type "text/plain";
  try_files $uri =404;

SSL Conf Nginx Snippet

vim /etc/nginx/snippets/ssl.conf

Copy-paste that content

ssl_dhparam /etc/ssl/certs/dhparam.pem;

ssl_session_timeout 1d;
ssl_session_cache shared:SSL:10m;
ssl_session_tickets off;

ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;

ssl_stapling on;
ssl_stapling_verify on;
resolver valid=300s;
resolver_timeout 30s;

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;

Create A Record with your DNS Provider pointing to the Droplet IP

For the following parts, you must have a domain name that will point to your droplet or else the acme-challenge of Let's Encrypt will not pass and you will not have SSL so the final Nginx config file will not apply to you.

Adding a domain name
Adding a domain name

Here we created a subdomain of codingdodo.com with an A record pointing to our Droplet IP Value.

Our final address will be odoo-14.codingdodo.com

Installing the Let's Encrypt certificate

In case the Odoo service is still running.

service odoo-14 stop

Basic Nginx Conf file to pass the Certbot acme-challenge

cd /etc/nginx/sites-available
vim odoo-14.codingdodo.com

We will first create a basic Nginx conf file to pass certbot acme-challenge:

upstream odoo_14 {

upstream odoochat_14 {

server {
    listen      80;
    listen [::]:80;
    server_name odoo-14.codingdodo.com;
    include snippets/letsencrypt.conf;

Symlink your site declaration from site-available to site-enabled.

ln -s /etc/nginx/sites-available/odoo-14.codingdodo.com /etc/nginx/sites-enabled/odoo-14.codingdodo.com

Always test the config with nginx -t and if everything is okay we reload Nginx

service nginx reload

Certbot acme-challenge

It is now time to create our SSL certificate.

certbot certonly --agree-tos --email [email protected] --webroot -w /var/lib/letsencrypt/ -d odoo-14.codingdodo.com

You should see

 - Congratulations! Your certificate and chain have been saved at:

Managing Auto renew

Let's Encrypt already created a cron in the crontab but Nginx needs to reload to take into consideration the new certificate so we will edit this file

vim /etc/letsencrypt/cli.ini

And add the line at the end.

deploy-hook = systemctl reload nginx

To test if our renew will work we can use the --dry-run flag to test it

certbot renew --dry-run

Final Nginx site conf for proxy mode multi workers

Now edit the odoo-14.codingdodo.com file again:

vim /etc/nginx/sites-available/odoo-14.codingdodo.com
upstream odoo_14 {

upstream odoochat_14 {

server {
    listen      80;
    listen [::]:80;
    server_name odoo-14.codingdodo.com;
	include snippets/letsencrypt.conf;
    location / {
        return 301 https://odoo-14.codingdodo.com$request_uri;

server {
    listen      443 ssl http2 default_server;
    listen [::]:443;
    server_name odoo-14.codingdodo.com ;

    ssl_certificate     /etc/letsencrypt/live/odoo-14.codingdodo.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/odoo-14.codingdodo.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/odoo-14.codingdodo.com/chain.pem;
	include snippets/ssl.conf;
	include snippets/letsencrypt.conf;

    proxy_buffers 16 64k;
    proxy_buffer_size 128k;

    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;
    proxy_set_header    X-Odoo-dbfilter   "codingdodo_demo";
    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;

    location / {
        proxy_pass  http://odoo_14;

    location /longpolling {
        proxy_pass http://odoochat_14;

    location ~* /web/static/ {
        proxy_cache_valid 200 60m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odoo_14;

    location ~* /website/image/ir.attachment/ {
        proxy_cache_valid 200 60m;
        proxy_buffering on;

        proxy_pass http://odoo_14;

    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
    gzip on;

Use nginx -t to test the new config, you should see:

root@ubuntu-s-4vcpu-8gb-amd-blr1-01:/etc/nginx/sites-available# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Now you can reload nginx.

service nginx reload

Updating the Odoo config file

vim /home/odoo/.odoorc_codingdodo_demo

Now that we have our reverse proxy we need to modify/add these lines

proxy_mode = True
workers = 4
max_cron_threads = 1
limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_request = 8192
limit_time_cpu = 600
limit_time_real = 1200

The number of workers depends on the RAM and CPU you choose during the creation of your droplet. Refer to this official documentation to calculate the appropriate number of workers.

  • Server with 2 CPU, 4 Thread
  • 30 concurrent users
  • 30 users / 6 = 5 <- theorical number of worker needed
  • (2 * 2) + 1 = 5 <- theorical maximal number of worker
  • We’ll use 4 workers + 1 for cron.
  • RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo

Restart Odoo and see logs

service odoo-14 restart

Go to https://odoo-14.codingdodo.com and in the meantime on the server check the logs

tail -f /var/log/odoo/odoo-14.log | ccze

In your browser access your domain name, you should see the login screen :

We now have a working odoo on DigitalOcean!
Hurray !

Setting the Firewall

Let's add some security!

ufw app list

If you followed this guide it should show you :

Available applications:
  Nginx Full
  Nginx HTTP
  Nginx HTTPS

First, we secure ssh connection

ufw allow OpenSSH

Now if you have installed Nginx with an SSL certificate

ufw allow 'Nginx Full'
ufw enable

The last line will ask you to confirm, enter y

Command may disrupt existing ssh connections. Proceed with operation (y|n)? y
Firewall is active and enabled on system startup

Create a sudo user for day to day actions

adduser codingdodo

Answer the prompt questions:

Changing the user information for codingdodo
Enter the new value, or press ENTER for the default
	Full Name []: CodingDodo
	Room Number []:
	Work Phone []:
	Home Phone []:
	Other []:
Is the information correct? [Y/n] Y

Now we update the rights for that user.

usermod -aG sudo codingdodo
rsync --archive --chown=codingdodo:codingdodo ~/.ssh /home/codingdodo

With DigitalOcean we already uploaded our ssh-key to the authorized_keys of the root so we are using Rsync to copy the folder with a new owner.

Wrapping up

This is the final Odoo config file

addons_path = /home/odoo/odoo-14/addons,/home/odoo/odoo-14-custom-addons
admin_passwd = $pbkdf2-sha512$25000$TwkBoDRGqBUi5LyXMiaE8A$SUyyCVfU1jk0YqiuTbHqVNmT31jw33fyh6tLMkA6t6lLSKpbnutYuQ.dVwQ2wIgWs2hf1OQmhNcHR9ofqGtSFg

And that's it for today. We will still need to do daily backups for our database and our filestore (located at

I don't have a simple strong solution to handle backups that I could quickly share into this already very long article, so I may come back and update it later.
