In this post, we will show you how to install Odoo 18 in Rocky Linux 10. ## Step 1 – Install Python packages and Odoo Dependencies Before starting, install the EPEL repository using the following command: ``` dnf install epel-release -y ``` Once EPEL is installed, run the following command to install Python and Odoo dependencies: ``` dnf install python3 python3-devel git gcc git redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel -y ``` Next, install the **wkhtmltox** to render HTML into a PDF using the following command: ``` dnf install https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos8.x86_64.rpm ``` Next, enable CRB repo. ``` dnf config-manager --set-enabled crb ``` Next, install required Perl extension. ``` dnf install -y perl-IPC-Run ``` ## Step 2 – Install PostgreSQL Odoo uses PostgreSQL as a database backend. First, add PostgreSQL repo. ``` dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm ``` Next, install PostgreSQL with the following command. ``` dnf install postgresql18 postgresql18-server postgresql18-devel -y ``` After installing PostgreSQL, initialize the PostgreSQL database with the following command: ``` /usr/pgsql-18/bin/postgresql-18-setup initdb ``` Sample output: ``` WARNING: using obsoleted argument syntax, try --help WARNING: arguments transformed to: postgresql-setup --initdb --unit postgresql * Initializing database in '/var/lib/pgsql/data' * Initialized, logs are in /var/lib/pgsql/initdb_postgresql.log ``` Next, start the PostgreSQL service and enable it to start at system reboot: ``` systemctl enable --now postgresql-18 ``` Next, create a user for Odoo with the following command: ``` su - postgres -c "createuser -s odoo18" ``` ## Step 3 – Install Odoo 18 First, add an odoo user to run the Odoo service: ``` useradd -m -U -r -d /opt/odoo18 -s /bin/bash odoo18 ``` Next, log in with the odoo user and download Odoo version 18 using the following command: ``` su - odoo18 git clone https://www.github.com/odoo/odoo --depth 1 --branch 18.0 /opt/odoo18/odoo ``` Next, change the directory to /opt/odoo18 and create a Python virtual environment: ``` cd /opt/odoo18 python3 -m venv odooenv ``` Next, activate the virtual environment: ``` source odooenv/bin/activate ``` Next, install the required dependencies using the following command: ``` pip3 install -r odoo/requirements.txt ``` Next, deactivate the virtual environment with the following command: ``` deactivate ``` Next, create an addons directory and exit from the odoo user with the following command: ``` mkdir /opt/odoo18/odoo-custom-addons exit ``` Next, create an Odoo configuration file using the following command: ``` nano /etc/odoo18.conf ``` Add the following lines: ``` [options] admin_passwd = secure-password db_host = False db_port = False db_user = odoo18 db_password = False addons_path = /opt/odoo18/odoo/addons, /opt/odoo18/odoo-custom-addons ``` Save and close the file. ## Step 4 – Create an Odoo Service File Next, you will need to create a service file to manage the Odoo service. You can create it using the following command: ``` nano /etc/systemd/system/odoo.service ``` Add the following lines: ``` [Unit] Description=Odoo18 Requires=postgresql-18.service After=network.target postgresql-18.service [Service] Type=simple SyslogIdentifier=odoo18 PermissionsStartOnly=true User=odoo18 Group=odoo18 ExecStart=/opt/odoo18/odooenv/bin/python3 /opt/odoo18/odoo/odoo-bin -c /etc/odoo18.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target ``` Save the file, then reload the systemd daemon with the following command: ``` systemctl daemon-reload ``` Next, start the enable the Odoo service using the following command: ``` systemctl enable --now odoo ``` You can check the status of the Odoo service using the following command: ``` systemctl status odoo ``` Sample output: ``` ● odoo.service - Odoo18 Loaded: loaded (/etc/systemd/system/odoo.service; disabled; preset: disabled) Active: active (running) since Tue 2025-10-21 02:43:04 EDT; 4s ago Invocation: a2fd6721e8bd483eaf7b9806f5de2a54 Main PID: 3127 (python3) Tasks: 4 (limit: 24809) Memory: 89.3M (peak: 91.3M) CPU: 1.507s CGroup: /system.slice/odoo.service └─3127 /opt/odoo18/odooenv/bin/python3 /opt/odoo18/odoo/odoo-bin -c /etc/odoo18.conf ``` ## Step 5 – Configure Firewall If you are using firewalls, then you will need to allow Odoo port 8069 through the firewall. You can allow it using the following command: ``` firewall-cmd --permanent --add-port=8069 ``` Next, reload the firewalld to apply the changes: ``` firewall-cmd --reload ``` ## Step 6 – Access Odoo 18 Web UI At this point, Odoo 18 is started and listening on port 8069. You can check it using the following command: ``` ss -antpl | grep 8069 ``` Sample output: ``` LISTEN 0 128 0.0.0.0:8069 0.0.0.0:* users:(("python3",pid=37537,fd=3)) ``` You can now access it using the URL **http://your-server-ip:8069**.
