Prerequisites to Install Odoo 11 on CentOS 7

Before we begin:

Log in as a sudo user on your CentOS machine and upgrade the system to the latest packages:

sudo yum update

Use the following command to enable the EPEL repository:

yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

We will use the Software Collections (SCL) repository to install Python 3.5 packages.

You can access newer versions of programming languages and services that are not included in the core repository by activating SCL. With the following command, the SCL repository can be enabled:

yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/centos-release-scl-rh-2-3.el7.centos.noarch.rpm

Use the following command to install Python 3.5 packages:

sudo yum install python3
sudo yum install python3-devel

Lastly, install git, pip, and all the tools needed to create Odoo dependencies:

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

Create Odoo User

Create a new system user and group with the home directory /opt/odoo in order to execute the Odoo service:

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

Install and Configure PostgreSQL

Install the PostgreSQL server and build a new PostgreSQL database cluster:

sudo yum install postgresql-server
sudo postgresql-setup initdb

After installation is finished, activate and launch the PostgreSQL service:

sudo systemctl enable postgresql
sudo systemctl start postgresql

Set up a PostgreSQL user with the same name as the system user you previously built, in this case odoo:

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

Install Wkhtmltopdf

A set of free command-line tools that can convert HTML to PDF and other image formats are offered by the wkhtmltox package. You require the wkhtmltopdf tool in order to print PDF reports. Odoo 0.12.1 is the preferred version, although it is not included in the official CentOS 7 repositories.

Run the following commands to download and install the recommended version:

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 11

In order to have more control over the versions and updates, we will install Odoo from the GitHub repository. We will also make use of virtualenv, a tool for building isolated Python environments.

Make sure you [switch to the user] “odoo” before you begin the installation process:

sudo su - odoo

You can use the following command to verify that you are logged in as an odoo user:

whoami

Now that the installation process is ready to begin, clone the odoo from the GitHub repository as follows:

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

Next, create a new virtual environment for our Odoo installation by issuing the following command:

cd /opt/odoo
python3 -m venv odoo11-venv

Enable the environment:

source odoo11-venv/bin/activate

and install all essential Python modules:

pip3 install -r odoo11/requirements.txt

Use the following commands to deactivate the environment when installation is finished and switch back to your sudo user:

deactivate

exit

It is advisable to install custom modules in a separate directory if you intend to do so. Run the following command to make a new directory for the custom modules:

sudo mkdir /opt/odoo/odoo11-custom-addons
sudo chown odoo: /opt/odoo/odoo11-custom-addons

Making a configuration file is the next step:

sudo nano /etc/odoo11.conf

[options]
; This is the password that allows database operations:
admin_passwd = superadmin_passwd
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/odoo11-custom-addons

Create a Systemd Unit File

We will make an odoo11.service unit file in the /etc/systemd/system/ directory with the following statements to run Odoo as a service:

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=/opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf
StandardOutput=journal+console
[Install]
WantedBy=multi-user.target

You should notify systemd that a new unit file has been created and launch the Odoo service by running:

sudo systemctl daemon-reload
sudo systemctl start odoo11

The following command can be used to verify service status:

sudo systemctl status odoo11

Output

● odoo11.service - Odoo11
   Loaded: loaded (/etc/systemd/system/odoo11.service; disabled; vendor preset: disabled)
   Active: active (running) since Wed 2018-03-28 20:13:30 UTC; 6s ago

           ├─16174 /usr/bin/scl enable rh-python35 -- /opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf

           └─16178 /opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf

Also, you can let the Odoo service start automatically when the system boots up if there are no errors:

sudo systemctl enable odoo11

Use the command listed below to view the messages that the Odoo service has logged:

sudo journalctl -u odoo11
