Step - 1 : Update Server

    sudo apt-get update 
    sudo apt-get upgrade

Step - 2 : Create Odoo User

    sudo adduser -system -home=/opt/odoo -group odoo

Step - 3 : Install PostgreSQL Server

    sudo apt-get install postgresql -y 
    sudo su postgres createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo15

Step - 4 : Install Python Dependencies

Install pip3

    sudo apt-get install -y python3-pip

Install package and dependencies 

    sudo apt-get install python-dev python3-dev
    libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential
    libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libpq-dev libjpeg8-dev
    liblcms2-dev libblas-dev libatlas-base-dev

    sudo apt-get install -y npm
    sudo apt-get install -y node-less
    sudo apt-get install xfonts-75dpi

Step - 5: Clone Odoo from git repository

Install git

    sudo apt-get install git

Clone Project Odoo 15

    cd /opt
    git clone ​https://www.github.com/odoo/odoo --depth 1 --branch 15.0 --single-branch

Change ownership of odoo folder:

sudo chown -R odoo:odoo /opt/odoo/*

Step - 6: Install Required Python Packages

All packages required packages is listed on requirement.txt file, to install run this following command:

    sudo pip3 install -r /opt/odoo/requirements.txt
    sudo cp /opt/odoo/debian/odoo.conf
    /etc/odoo.conf

Step - 7: Install Wkhtmltopdf

Odoo use Wkhtmltopdf to make pdf report from HTML data format, to install Wkhtmltopdf you need to download it by used this command:

    wget ​https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.focal_amd64.deb

Then install the .deb file:

    sudo apt install ./wkhtmltox_0.12.6-1.focal_amd64.deb

Step - 8: Settup Conf File

The configuration of Odoo like addon path, database connection, port etc is store in odoo.conf file. There are sample conf file that we can use to our installation, wen need to put the conf file into /etc folder: 

    sudo cp /opt/odoo/debian/odoo.conf /etc/odoo.conf

Here is my conf file for you example:

   [options]

    ; This is the password that allows database operations:
    admin_passwd = adminPassWzOrd

    db_host = localhost
    db_maxconn = 64

    db_name = False
    db_password = odooPassword

    db_port = 5432

    db_sslmode = prefer
    db_template = template0

    db_user = odoo15
    dbfilter =

    addons_path = /opt/odoo/addons
    logfile = /var/log/odoo/odoo.log

Settup Log file:

    sudo mkdir /var/log/odoo
    sudo chown odoo:odoo /var/log/odoo

Step - 9: Settup Odoo Service

Create a service file ‘odoo.service’ in /etc/systemd/system:

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

Add the following content to the newly created service file:

   [Unit]

   Description=Odoo
   Documentation=http://www.odoo.com

   [Service]

   # Ubuntu/Debian convention:
   Type=simple

   User=odoo
   ExecStart=/opt/odoo/odoo-bin -c /etc/odoo.conf

   [Install]
   WantedBy=default.target

Set the permissions for the root user to this service file:

    sudo chmod 755 /etc/systemd/system/odoo.service
    sudo chown root: /etc/systemd/system/odoo.service

Step - 10: Test Odoo

Set the permissions for the root user to this service file:

    sudo systemctl start odoo.service

Then check the status of the service using the following command. And if it depicts as active, the installation of Odoo was successful:

    sudo systemctl status odoo.service

Now you can access Odoo from your favorite browser, type the following URL:

    “http://localhost:8069”

This will redirect you to the database creation page if everything is set up correctly.

Create Database Odoo Ubuntu

*Note: Master Password is admin_passwd that we have set in odoo.conf in previous step.

Nginx as Reverse Proxy Odoo 15

Nginx is a popular webserver that commonly use in production server, we use Nginx as reverse proxy in order to simplify your user to acces Odoo without the Port number in ther URL.

Follow this step to install and configure Nginx as reverse proxy:

Install Nginx:

    sudo apt install nginx

Start the Nginx service with the use of the following command:

    sudo service nginx start

Then remove the default virtual host’s symlink since we won’t be using it any more:

    sudo rm /etc/nginx/sites-enabled/default

 Create new Virtual Host configuration:

    sudo nano /etc/nginx/sites-available/localhost-proxy

Copy paste this following configuration:

    server {
       server_name localhost​; //replace server name with your domain or ip address
       listen 80;    
       access_log /var/log/nginx/testing-access.log;
       error_log /var/log/nginx/testing-error.log;
 
 ​   location / {
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_pass http://localhost:8069/pembukuan/;
            }
    }

    server {
        listen      80;
        listen      [::]:80;
        server_name ​localhost;
        return      301 ​https://localhost$request_uri;
    }

Enable both sites by creating symbolic links to the sites-enabled directory:

    sudo ln -s /etc/nginx/sites-available/localhost-proxy /etc/nginx/sites-enabled/localhost-proxy

Test the configuration to ensure there are no errors:

    sudo nginx -t

If there are no errors, then restart Nginx:

    sudo service nginx restart

Test the reverse proxy by accessing localhost from your browser, you will have Odoo page. You can modified the configuration above with your real domain or IP address in production server.
