2K

Odoo is a business software that comes packed with CRM, e-commerce, billing, accounting, project management, manufacturing, warehouse, and inventory apps. The Community version is an open-source version, while the Enterprise version adds proprietary features and services to the Community edition.

At FOSS Linux, we are focused on open-source apps, so in this tutorial, we are going to install and configure the Oddo community version on CentOS.

Installing Odoo 12 on CentOS

We shall execute commands using the root user.

1. Update System

yum update

The server will ask to update or no. Type “y” and hit enter. It will get some time to update the system.

2. Configure Needed Repositories

Enable Epel repository:

yum install epel-release

Enable the Software Collections (SCL) repository:

yum install centos-release-scl

Enable SCL Repository

3. Install Python 3.6 and Dependencies

yum install rh-python36

Install needed dependencies.

yum install bzip2-devel freetype-devel nodejs-less libxslt-devel openldap-devel libjpeg-devel gcc

4. Create Odoo User

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

5. Install and configure PostgreSQL

Check repositories from the official site and install the Postgres repository for Centos 7 64bit.

rpm -Uvh https://yum.postgresql.org/11/redhat/rhel-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Now Install PostgreSQL 11 server.

yum install postgresql11-server

Initialize PGDATA

Initialize the database using the below command. It should create a data directory and other configuration files on the system.

/usr/pgsql-11/bin/postgresql-11-setup initdb

Now, check PostgreSQL Service Status.

systemctl status postgresql-11.service

If service is not started. Run the following command to start service:

systemctl start postgresql-11.service

Enable service on the system boot.

systemctl enable postgresql-11.service

Need to Check and Verify PostgreSQL Installation.

su - postgres -c "psql"

If you want, you can create a password too.

 \password postgres

Create a PostgreSQL user.

su - postgres -c "createuser -s odoousr"

6. Install Wkhtmltopdf

It is an open-source tool that Odoo uses to make HTML in PDF formats so that it can print PDF reports.

wget https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox-0.12.5-1.centos7.x86_64.rpm

“wget” is not available. need to install it first

yum install wget -y

Install the downloaded package using below command:

yum localinstall wkhtmltox-0.12.5-1.centos7.x86_64.rpm

7. Install and configure Odoo 12

Git is not installed on your system Install git first.

 yum install git -y

Change user to odoo user:

su - odoousr

Now we are going to clone odoo 12 from its repository. We are going to download it to the “/opt/odoo/odoo12” directory.

git clone https://www.github.com/odoo/odoo --depth 1 --branch 12.0 /opt/odoo/odoo12

To enable python36, run the following command:

scl enable rh-python36 bash

8. Create a new virtual environment

Go to odoo directory:

cd /opt/odoo

Run the below command to create an environment.

python3 -m venv odoo12-venv

Activate the environment:

source odoo12-venv/bin/activate

Upgrade pip:

pip install --upgrade pip

Install the Wheel library, followed by all the required Python modules.

pip3 install wheel

pip3 install -r odoo12/requirements.txt

After installation is complete, Deactivate the virtual environment and return to the root user.

9. Other configurations for Odoo12

Create a directory for custom modules.

 mkdir /opt/odoo/odoo12-custom-addons

chown odoousr: /opt/odoo/odoo12-custom-addons

Create a configuration file for the Odoo12.

vim /etc/odoo12.conf

If vim is not available, you should install it first, or you can use any editor of your choice.

yum install vim

Add the following lines to file:

 [options]
; This is the password that allows database operations:
admin_passwd = Foss@343fd<?Linux
db_host = False
db_port = False
db_user = odoousr
db_password = False
addons_path = /opt/odoo/odoo12/addons,/opt/odoo/odoo12-custom-addons
logfile = /var/log/odoo12/odoo.log

Save, and exit. Then create a log folder and grant permission to it.

mkdir -p /var/log/odoo12

chown -R odoousr: /var/log/odoo12

10. Manually start odoo12

Now start service and check whether it is working correctly. Change the user and then start command.

su - odoousr

/usr/bin/scl enable rh-python36 -- /opt/odoo/odoo12-venv/bin/python3 /opt/odoo/odoo12/odoo-bin -c /etc/odoo12.conf

Check Odoo12 port is up and running. Then open another terminal and run below command:

netstat -tunlp | grep 8069

Odoo12 Port

11. Configure firewall

Check firewall status.

systemctl status firewalld

If the service has not started, start it using the following command:

systemctl start firewalld

Add firewall rules and reload firewall:

firewall-cmd --zone=public --permanent --add-service=http

firewall-cmd --zone=public --permanent --add-port=8069/tcp

systemctl reload firewalld

12. Browse Application

http://Ip or domain name:8069

You will get the Start page.

If you get a “Service Unavailable” message, temporary change Selinux mode.

setenforce 0

13. Configure Odoo12 run as a Service

Create a systemd file and add the following content to the file:

vim /etc/systemd/system/odoo12.service

[Unit]
Description=Odoo12
Requires=postgresql-11.service
After=network.target postgresql-11.service

[Service]
Type=simple
SyslogIdentifier=odoo12
PermissionsStartOnly=true
User=odoousr
Group=odoousr
ExecStart=/usr/bin/scl enable rh-python36 -- /opt/odoo/odoo12-venv/bin/python3 /opt/odoo/odoo12/odoo-bin -c /etc/odoo12.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

Save, and exit.

Reload systemctl daemon.

systemctl daemon-reload

14. Now stop previously started odoo12

Check process.

ps -aux | grep odoo

Odoo ProcessKill process.

kill -9 28416 28417 28420

Make sure to replace process IDs with yours.

15. Now start odoo12  service

systemctl start odoo12

Check status.

systemctl status odoo12

Monitor the log file using the following command:

tail -f /var/log/odoo12/odoo.log

Check status and enable Odoo service on system boot.

systemctl enable odoo12

16. Browse the web site and continue

http://Ip Or Domain name:8069

Add a Master password, database name, and other details.

Then click “create database” (Here I added demo data too). You should be redirected to the welcome page.

After sign out from the above page, you should go to the login page.

That’s all about the installation of the latest Odoo 12 on Centos 7. I hope you enjoyed the tutorial.
