Odoo is an all-in-one management software that offers a range of business applications that form a complete suite of enterprise management applications targeting companies of all sizes. Odoo is an all-in-one business software including CRM, website/e-commerce, billing, accounting, manufacturing, warehouse and project management, and inventory.

Updating System Packages

sudo yum update

sudo yum install epel-release

Install the packages from the Software Collections (SCL) repository.

sudo yum install centos-release-scl

Proceed to install Python 3.5 packages with the command below:

sudo yum install rh-python35

Building Odoo requires some dependencies such as git and pip.

sudo yum install git gcc wget nodejs-less libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel postgresql-devel

Create new user,

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

Now install postgresql

sudo yum install postgresql-server
sudo postgresql-setup initdb

After initialization, enable and start the PostgreSQL service

sudo systemctl enable postgresql
sudo systemctl start postgresql

We need to create a PostgreSQL user; this username has to be the same name as the previously created system user, in our case odoo.

sudo su - postgres -c "createuser -s odoo"

Install Wkhtmltopdf

wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.1/wkhtmltox-0.12.1_linux-centos7-amd64.rpm
sudo yum localinstall wkhtmltox-0.12.1_linux-centos7-amd64.rpm

Install and Configure Odoo

Before starting with the installation process, we need to switch to the odoo user that was created earlier.

sudo su - odoo

Next, we are going to install Odoo from the GitHub repository so we can have more control over versions and updates.

git clone https://www.github.com/odoo/odoo --depth 1 --branch 11.0 /opt/odoo/odoo11

Enable software collections so we can access the python 3.5 binaries:

scl enable rh-python35 bash

Next, activate the environment created with the command below:

source odoo11-venv/bin/activate
sudo mkdir /opt/odoo/custom-addons-for-odoo11
sudo chown odoo: /opt/odoo/custom-addons-for-odoo11

Lastly in this section, we need to create a configuration file:

sudo nano /etc/odoo11.conf

[options]
; This is the password that allows database operations:
admin_passwd = admin_password
db_host = False
db_port = False
db_user = odoo
db_password = False
addons_path = /opt/odoo/odoo11/addons
; If you are using custom modules
; addons_path = /opt/odoo/odoo11/addons,/opt/odoo/custom-addons-for-odoo11

Note: Remember to change the admin password to a more secure password and modify the addons path if you are using custom modules.

Save and close the file.

We need to create a systemd unit file called odoo11.service in order to run odoo as a service unit file in the /etc/systemd/system/ directory with the following contents:

sudo nano /etc/systemd/system/odoo11.service

[Unit]
Description=Odoo11
Requires=postgresql.service
After=network.target postgresql.service

[Service]
Type=simple
SyslogIdentifier=odoo11
PermissionsStartOnly=true
User=odoo
Group=odoo
ExecStart=/usr/bin/scl enable rh-python35 -- 
/opt/odoo/odoo11-venv/bin/python3 
/opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

Save and close the file.

Next, we need to reload systemd since we just created a new unit file and start the Odoo service by executing:

sudo systemctl daemon-reload
sudo systemctl start odoo11

We can now check the service status with the command below:

sudo systemctl status odoo11

If there are no errors, you can enable the Odoo service to be automatically started at boot time with the command below:

sudo systemctl enable odoo11

Odoo, by default, uses the port 8069, therefore you are going to open the port on your firewall (CSF) using the command below:

nano /etc/csf/csf.conf

Navigate to the SECTION: IPv4 Port Settings and add 8069 to the list of ports. Open your browser and type: your _ domain _ or _ IP _ address:8069
