Step 1: Install Odoo 18

1.Clone the Odoo Repository:

sudo git clone https://github.com/odoo/odoo --depth 1 --branch 18.0 /opt/odoo

2.Create a Python Virtual Environment:

 cd /opt/odoo
python3 -m venv odoo-venv
source odoo-venv/bin/activate

 

3.Install Python Packages:

 

     pip install wheel
     pip install -r /opt/odoo/requirements.txt

 

 

Step 2: Configure Odoo

    sudo nano /etc/odoo.conf

    Or 

  

  if you want to add odoo.conf in odoo folder itself and run through there 

    Add the following configuration:

 [options]
admin_passwd = your_admin_password
db_host = False
db_port = False
db_user = odoo
db_password = your_db_password
addons_path = /opt/odoo/addons
logfile = /var/log/odoo/odoo.log
 

Replace your_admin_password and your_db_password with secure passwords.

 

2.Set Permissions:

  sudo chown odoo:odoo /etc/odoo.conf

  sudo chmod 640 /etc/odoo.conf

3. Create Log Directory:

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

 

Step 3: Start and Stop Odoo Manually

 Starting Odoo

  1 Navigate to the Odoo Directory:

      cd /opt/odoo

 2 Activate the Virtual Environment:

       source odoo-venv/bin/activate

 3 Start Odoo:

         python3 odoo-bin -c /etc/odoo.conf
 

  Odoo will start, and you should see log messages in the terminal.

 

Stopping Odoo:

    To Stop Odoo, use CTRL+C in the terminal where Odoo is running. This will terminate the process.

 Step 4: Create Odoo Systemd Service

1. Create a systemd service file:

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

2. Add the following content to the service file:

         [Unit]

Description=Odoo
Documentation=http://www.odoo.com
After=network.target postgresql.service

[Service]
# Unix user that runs the Odoo service
User=odoo
# Working directory
WorkingDirectory=/opt/odoo
# Command to start Odoo (the virtual environment and configuration file are important)
ExecStart=/opt/odoo/odoo-venv/bin/python3 /opt/odoo/odoo-bin -c /etc/odoo.conf
# Restart Odoo service automatically if it crashes
Restart=always

[Install]
# Target for starting the service
WantedBy=multi-user.target

       

 3.Reload the systemd daemon to apply the new service:

    

      sudo systemctl daemon-reload
 

 4.Start the Odoo service:

    sudo systemctl start odoo 

5. Check the status of the Odoo service:

       If Odoo is running correctly, you should see output indicating that it is "active (running)."    

6.Enable Odoo to start automatically on system boot:

       sudo systemctl enable odoo

 

Step 5: Manage Odoo with Systemd

1. Start Odoo:

     sudo systemctl start odoo
 

2. Stop Odoo:

     sudo systemctl stop odoo
 

3. Restart Odoo:

    sudo systemctl restart odoo

4. Check Odoo status:

    sudo systemctl status odoo

5. Enable Odoo to start on boot:

     sudo systemctl enable odoo

6. Disable Odoo from starting on boot:

         sudo systemctl disable odoo

Step 6: Troubleshooting

1.Check Odoo logs: If Odoo is not running correctly, you can check the logs for any errors.

       tail -f /var/log/odoo/odoo.log
 

2. View system logs for Odoo service: You can also check the system logs related to the Odoo service using the journalctl command.

 

      sudo journalctl -u odoo

 

3. Ensure the PostgreSQL service is running: Odoo depends on PostgreSQL. Ensure it’s up and running:

 

       sudo systemctl status postgresql
 

Step 7: Access Odoo in a Browser

 Open your browser and access Odoo:

        Go to http://localhost:8069 or your ipaddress:8069 to access the Odoo web interface.

 

 Create a new database:

 

       Follow the instructions on the screen to create your Odoo database and log in
