Step 3: Install PostgreSQL and Create User


sudo apt install -y postgresql
sudo -u postgres createuser -s odoo18

Step 4: Get Odoo Source Code


#Switch to odoo18 user:

sudo -i -u odoo18

#Clone Odoo 18 source code:

cd /opt/odoo18
wget https://github.com/odoo/odoo/archive/refs/heads/18.0.zip -O odoo18.zip

#Unzip & remove extra content:

unzip odoo18.zip
mv odoo-18.0/* odoo-18.0/.[!.]* .
rm -rf odoo-18.0 odoo18.zip

Step 5: Create Python Virtual Environment


#Inside /opt/odoo18:
cd /opt/odoo18
python3 -m venv venv
source venv/bin/activate

#Upgrade pip:
pip install --upgrade pip wheel setuptools

#Install Python dependencies:
pip install -r requirements.txt

#Deactivate venv & exit from odoo18 user:
deactivate
exit

Step 6: Create Odoo Configuration File

Create & edit a file witn name 'odoo18.conf' inside etc:


sudo nano /etc/odoo18.conf

Add the following content in 'odoo18.conf':


[options]
; Database
admin_passwd = 12345
db_host = False
db_port = False
db_user = odoo18
db_password = False
xmlrpc_port = 8069

addons_path = /opt/odoo18/addons

Grant access to user odoo18 to the file:


sudo chown odoo18:odoo18 /etc/odoo18.conf
sudo chmod 640 /etc/odoo18.conf

Step 7: Verify Installation

Run the odoo server by command:


sudo -i -u odoo18
cd /opt/odoo18
source venv/bin/activate 
python3 odoo-bin -c /etc/odoo18.conf

Odoo should be running at:


http://localhost:8069

If you face an error:


- Try to read the error text
- If it is some dependancey issue than install it by using "pip install dependancy_name
- If it is port related issue, than try to kill the servic which is using the same port
- If it is permission like issue than try to grant access to 'odoo18' user
- If it is database related issue than fix it by edit postgres config file

Step 8: Access Odoo 18

Open your browser and navigate to http://localhost:8069.
If you are using a remote server, replace localhost with your server's IP address.

Optional: Nginx as a Reverse Proxy

If you want to serve Odoo behind a domain name, you can install and configure Nginx as a reverse proxy.
