How To Install Odoo 11 In CentOS7.In this tutorial, we’ll walk you through how to install Odoo 11 using Git source and Python virtual environment on a CentOS 7 machine. Before you beginLog in to you CentOS machine as a sudo user and update the system to the latest packages:sudo yum updateEnable the EPEL repository by typing:sudo yum install epel-releaseWe will install Python 3.5 packages from the Software Collections (SCL) repository.By enabling SCL you will gain access to the newer versions of programming languages and services which are not available in the core repositories. Enable the SCL repository with the following command:sudo yum install centos-release-sclInstall Python 3.5 packages, with the following command:sudo yum install rh-python35Finally install git, pip and all the tools required to build Odoo dependencies:sudo yum install git gcc wget nodejs-less libxslt-devel bzip2-devel openldap-devel Create Odoo userCreate a new system user and group with home directory /opt/odoo that will run the Odoo service:sudo useradd -m -U -r -d /opt/odoo -s /bin/bash odoo Install and configure PostgreSQLInstall the PostgreSQL server and create a new PostgreSQL database cluster:sudo yum install postgresql-server sudo postgresql-setup initdbOnce the installation is completed, enable and start the PostgreSQL service:sudo systemctl enable postgresql sudo systemctl start postgresqlCreate a PostgreSQL user with the same name as the previously created system user, in our case odoo:sudo su - postgres -c "createuser -s odoo" Install WkhtmltopdfThe wkhtmltox package provides a set of open-source command line tools which can render HTML into PDF and various image formats. In order to print PDF reports, you will need the wkhtmltopdf tool. The recommended version for Odoo is 0.12.1 which is not available in the official CentOS 7 repositories.To download and install the recommended version run the following commands:wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.1/wkhtmltox-0.12.1_linux-centos7-amd64.rpmsudo yum localinstall wkhtmltox-0.12.1_linux-centos7-amd64.rpm Install and configure Odoo 11We will install Odoo from the GitHub repository so we can have more control over versions and updates. We will also use virtualenv which is a tool to create isolated Python environments.Before starting with the installation process, make sure you “odoo”:sudo su - odooTo confirm that you are logged-in as odoo user you can use the following command:whoamiNow we can start with the installation process, first clone the odoo from the GitHub repository:git clone https://www.github.com/odoo/odoo --depth 1 --branch 11.0 /opt/odoo/odoo11Enable software collections so we can access the python 3.5 binaries:scl enable rh-python35 bashCreate a new virtual environment for our Odoo installation with:cd /opt/odoopython3 -m venv odoo11-venvactivate the environment:source odoo11-venv/bin/activateand install all required Python modules:pip3 install -r odoo11/requirements.txtIf you encounter any compilation errors during the installation, make sure that you installed all of the required dependencies listed in the Before you begin section.Once the installation is completed deactivate the environment and switch back to your sudo user using the following commands:deactivateexitIf you plan to install custom modules it is best to install those modules in a separate directory. To create a new directory for the custom modules run:sudo mkdir /opt/odoo/odoo11-custom-addons sudo chown odoo: /opt/odoo/odoo11-custom-addonsNext, we need to create a configuration file: ; 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-addonsDo not forget to change the superadmin_passwd to something more secure and adjust the addons_path if you’re using custom modules. Create a systemd unit fileTo run odoo as a service we will create a odoo11.service unit file in the /etc/systemd/system/ directory with the following contents: DescriptionOdoo11 Requirespostgresql.service Afternetwork.target postgresql.service Typesimple SyslogIdentifierodoo11 PermissionsStartOnlytrue Userodoo Groupodoo ExecStart/usr/bin/scl enable rh-python35 -- /opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf StandardOutputjournal+console WantedBymulti-user.targetNotify systemd that we have created a new unit file and start the Odoo service by executing:sudo systemctl daemon-reload sudo systemctl start odoo11You can check the service status with the following command:sudo systemctl status odoo11● 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 Main PID: 16174 (scl) CGroup: /system.slice/odoo11.service ├─16174 /usr/bin/scl enable rh-python35 -- /opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.conf ├─16175 /bin/bash /var/tmp/sclihoNjg └─16178 /opt/odoo/odoo11-venv/bin/python3 /opt/odoo/odoo11/odoo-bin -c /etc/odoo11.confand if there are no errors you can enable the Odoo service to be automatically started at boot time:sudo systemctl enable odoo11If you want to see the messages logged by the Odoo service you can use the command below:sudo journalctl -u odoo11 Test the InstallationOpen your browser and type: http:// :8069 ConclusionThis tutorial walked you through the installation of Odoo 11 on CentOS 7 in a Python virtual environment.
