1. Log in as root to your server via SSH
If you want to check the version of CentOS installed on your machine you can run the following command:
the output we receive is:
CentOS Linux release 7.5.1804 (Core)
2. Update the system
By running the command below, you can update your server:
Once this is done, enable the EPEL repository by typing:
yum install epel-release
3. Install Python 3.5 packages and Odoo dependencies
With the next command, you can enable the Software Collections (SCL) repository so you can install Python 3.5 packages.
yum install centos-release-scl
Execute the following command to install Python 3.5:
yum install rh-python35
With the next command, you should install all the tools and dependencies that you need to build the latest Odoo 12.
yum install git gcc wget nodejs-less libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel
4. Create Odoo user
Create a new system user and group that you need to run the Odoo service. In this case, we will define /opt/odoo as a home directory.
useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
Feel free to name the user whatever you like, just don’t forget to create a PostgreSQL user with the same name.
5. Install and configure PostgreSQL
You can first list the available packages:
yum list postgresql*
We will use PostgreSQL version 9.6 in this tutorial. If you do not have this version of the list, you can manually add from the Postgres Yum repository using the command below:
yum install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-redhat96-9.6-3.noarch.rpm -y
Install PostgreSQL 9.6 by executing:
yum install postgresql96 postgresql96-server postgresql96-contrib postgresql96-libs -y
Initialize your database:
Start the PostgreSQL:
systemctl start postgresql-9.6.service
Optional: You can configure PostgreSQL to start on boot by enabling it:
systemctl enable postgresql-9.6.service
Next, you need to create a PostgreSQL user who uses the same name as the user you are creating already for Odoo.
su - postgres -c "createuser -s odoo"
6. Install Wkhtmltopdf
The wkhtmltopdf package is an open source tool that Odoo uses to make HTML in PDF formats so that it can print PDF reports. We will install version 0.12.5 which is not available in the official CentOS 7 repositories. In order to download and install this version you need to run the following commands:
cd /opt/ wget https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox-0.12.5-1.centos7.x86_64.rpm yum localinstall wkhtmltox-0.12.5-1.centos7.x86_64.rpm
7. Install and configure Odoo 12
We are going to install Odoo 12 from GitHub repository and use virtualenv so can create an isolated Python environment. The first step you need to do is switch to the odoo user:
su - odoo
Clone the Odoo from the GitHub repository:
git clone https://www.github.com/odoo/odoo --depth 1 --branch 12.0 /opt/odoo/odoo12
In the next step we should enable the software collections in order to access the python 3.5 binaries:
scl enable rh-python35 bash
Then create a new virtual environment with the commands below:
cd /opt/odoo python3 -m venv odoo12-venv
activate the virtual environment:
Upgrade pip with the command and install the Wheel library:
pip install --upgrade pip pip3 install wheel
Run the following command to install all the required Python modules:
pip3 install -r odoo12/requirements.txt
When the installation is complete, you can deactivate the virtual environment and return to the root user with the commands:
deactivate && exit exit
If you consider that you will use custom modules for your Odoo instance you should install them in a separate directory. Create a new directory and change the owner to odoo with the following commands:
mkdir /opt/odoo/odoo12-custom-addons chown odoo: /opt/odoo/odoo12-custom-addons
Next step is to create a configuration file for the Odoo.
paste the following lines in the configuration file:
[options] ; This is the password that allows database operations: admin_passwd = master_password db_host = False db_port = False db_user = odoo db_password = False addons_path = /opt/odoo/odoo12/addons ; You can enable log file with uncommenting the next line ; logfile = /var/log/odoo12/odoo.log ; If you are using custom modules ; addons_path = /opt/odoo/odoo12/addons,/opt/odoo/odoo12-custom-addons
Please do not forget to change the master_password with a new strong password. You can generate one through the command line. Save and close the file.
8. Create a systemd unit file
In the next step, we will create a service unit file so we can run Odoo as a service.
Open your text editor :
and paste the configuration below:
[Unit] Description=Odoo12 Requires=postgresql-9.6.service After=network.target postgresql-9.6.service [Service] Type=simple SyslogIdentifier=odoo12 PermissionsStartOnly=true User=odoo Group=odoo ExecStart=/usr/bin/scl enable rh-python35 -- /opt/odoo/odoo12-venv/bin/python3 /opt/odoo/odoo12/odoo-bin -c /etc/odoo.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target
You need to reload the daemon so he can take the new unit that we created in systemd.
Finally, we can start the Odoo instances with the command:
systemctl start odoo12
To check the status for the Odoo service you can execute the following command:
systemctl status odoo12
● odoo12.service - Odoo12 Loaded: loaded (/etc/systemd/system/odoo12.service; disabled; vendor preset: disabled) Active: active (running) since Thu 2018-10-18 07:28:28 CDT; 6s ago Main PID: 24592 (scl) CGroup: /system.slice/odoo12.service ├─24592 /usr/bin/scl enable rh-python35 -- /opt/odoo/odoo12-venv/bin/python3 /opt/odoo/odoo12/odoo-bin -c /etc/odoo.conf ├─24593 /bin/bash /var/tmp/scly7P6bo └─24596 /opt/odoo/odoo12-venv/bin/python3 /opt/odoo/odoo12/odoo-bin -c /etc/odoo.conf
If there are no errors you can enable the Odoo service to start on boot with the command:
systemctl enable odoo12
For more information about the messages logged by the Odoo service you can check:
journalctl -u odoo12
9. Test the installation
Now when you have Odoo running on your server it is time to open your favorite browser and navigate to http://<your_server_IP_address>:8069
If that the installation has been successfully completed, you should be able to see the Odoo screen so you can create your first database.
Congratulations, if you follow carefully our instructions in this tutorial, you have installed the latest Odoo 12 on your CentOS 7 VPS. You can create your first database and start using the lastest Odoo 12.
