This article will show you how to install Odoo 15 on CentOS 9 / AlmaLinux 9
previous requirements
- Operating system: CentOS 9 or AlmaLinux 9
- Access: Possibility to connect to the server via SSH.
- permissions : a user with root privileges (ie, able to use the ‘sudo’ command).
- Minimum version of Python recommended 3.7.0 (or higher) This will be required to install the Python dependency “Pillow 9.5.0” or higher.
Note: Although you can run all of the commands below from the root user, it is highly recommended that you use a separate user with ‘sudo’ privileges.
If you have a version of AlmaLinux 8 we recommend: Upgrade from AlmaLinux 8 to AlmaLinux 9
Step 1 – Login to the AlmaLinux 9 server via SSH as root user:
ssh root@IP_Address -p Port_number
Replace ‘IP_Address’ and ‘Port_number’ with the respective IP address and SSH port number of your server.
Step 2 – Update the system
Once you are connected to your server, refresh the list of available packages using the following command.
sudo dnf update -y
Step 3: Install Python and other dependencies
Now, you need to install Python and other required dependencies on your server.
sudo dnf install python3 python3-devel git gcc git redhat-rpm-config libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel -y
Verifique que la versión de python es al menos 3.7.0
python3 --version
Step 4: Install the wkhtmltopdf package
Wkhtmltopdf is the package that allows Odoo 15 to print PDF reports. It converts HTML (web page markup) to PDF, but it is not present in the official package list or in the EPEL repository.
sudo dnf install Once all the packages are installed, it’s time to install PostgreSQL and Odoo. Below are the steps for its installation.
Next, you will need to install the PostgreSQL package on your server.
Step 5 – Create a dedicated Linux user for Odoo
You need to create a dedicated Linux user to keep Odoo’s permissions strict and predefined.
The following command will create a user named odoo and a group of users with the same name. The user’s home directory will be /opt/odoo and Bash will be the default shell.
sudo useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
Note: You can choose any name for the user, but be sure to use that same name in the next step when you go to create a database user.
Step 6: Install PostgreSQL
You can install PostgreSQL with the following command:
sudo yum -y install postgresql.x86_64 postgresql-server.x86_64 postgresql-contrib.x86_64
Step 7: Initialize the PostgreSQL database
sudo /usr/bin/postgresql-setup initdb
Step 8 – Start the PostgreSQL process and make sure the database process is always running
sudo systemctl start postgresql sudo systemctl enable postgresql
Step 9: Create a new PostgreSQL user (remember to use the username from the previous step)
Now the user will have the correct place to create a new PostgreSQL user configured for Odoo with the following command:
sudo su - postgres -c "createuser -s odoo"
Step 10: Installation of Odoo
Secondly, for Odoo installation, login to Odoo user and download Odoo 15.
sudo su - odoo git clone --depth 1 --branch 15.0 /opt/odoo/odoo15 cd /opt/odoo
Step 11: Set up the new Python virtual environment and its activation
The virtual environment is necessary to separate the Odoo Python modules from the system Python modules so that the two do not interfere with each other.
python3 -m venv odoo15-venvsource odoo15-venv/bin/activate
Step 12: Install the required dependencies
Install the required dependencies or the python module
pip3 install -r odoo15/requirements.txt
Step 13: Disable dependencies
Deactivate the virtual environment and revert to the previous system user (you no longer have to do anything with the odoo user)
deactivate
Step 14: Prepare for Odoo Custom Plugins
Create a separate directory for odoo custom plugins and change its owner to odoo user
sudo mkdir /opt/odoo/odoo15-custom-addonsexit
sudo mkdir /var/log/odoo15 && touch /var/log/odoo15/odoo.log
chown odoo:odoo /var/log/odoo15 ; chown odoo:odoo /var/log/odoo15/odoo.log
Step 15 – Create a configuration file for your Odoo instance
Now, it’s time to configure Odoo using several commands:
sudo nano /etc/odoo15.conf
Add the following lines:
[options] admin_passwd = odoo_master_password db_host = False db_port = False db_user = odoo db_password = False xmlrpc_port = 8069 logfile = /var/log/odoo15/odoo.log logrotate = True addons_path = /opt/odoo/odoo15/addons,/opt/odoo/odoo15-custom-addons
Close the after Odoo configuration, but don’t forget to save it.
Step 16: Create a system service file for Odoo
A system service file for Odoo can be obtained with the following command:
sudo nano /etc/systemd/system/odoo.service
Add the following lines:
[Unit] Description=Odoo15 #Requires=postgresql-10.6.service #After=network.target postgresql-10.6.service [Service] Type=simple SyslogIdentifier=odoo15 PermissionsStartOnly=true User=odoo Group=odoo ExecStart=/opt/odoo/odoo15-venv/bin/python3 /opt/odoo/odoo15/odoo-bin -c /etc/odoo15.conf StandardOutput=journal+console [Install] WantedBy=multi-user.target
Save and close the file, then reload the systemd daemon to apply the changes:
sudo systemctl daemon-reload
Next, start the Odoo service and enable it to start on system reboot:
sudo systemctl start odoo sudo systemctl enable odoo
Now check the status of the Odoo service with the following command:
sudo systemctl status odoo
You should get the following output:
odoo.service - Odoo15 Loaded: loaded (/etc/systemd/system/odoo.service; disabled; vendor preset: disabled) Active: active (running) since Sun 2021-06-06 09:41:59 EDT; 4s ago Main PID: 23729 (python3) Tasks: 4 (limit: 25014) Memory: 55.6M CGroup: /system.slice/odoo.service └─23729 /opt/odoo/odoo15-venv/bin/python3 /opt/odoo/odoo15/odoo-bin -c /etc/odoo.conf Nov 25 21:41:59 AlmaLinux systemd[1]: Started Odoo15.
At this point, Odoo starts up and listens on port 9069. You can verify this with the following command:
ss -antpl | grep 8069
You should get the following output:
LISTEN 0 129 0.0.0.0:8069 0.0.0.0:* users:(("python3",pid=23729,fd=4))
Step 17 – Configuring the Firewall
The firewall will allow you port 9069. But here, you can also use the following command:
sudo firewall-cmd --permanent --zone=public --add-port=8069/tcp
Now just apply the changes:
sudo firewall-cmd --reload
Step 19: Access the odoo web user interface
Insert your Odoo master password, database, admin username, password, email and click the button Create database . You should see the Odoo dashboard on the following page:
odoo-0
Congratulations! You have successfully installed Odoo 15 on AlmaLinux 9.
