Odoo is currently one of the most popular tool for business purposes. It has a community edition, that allows managing ERP at very low cost. Odoo was previously known as OpenERP. Odoo requires to be installed on a dedicated server or VPS. Odoo 13 had come out on October, 2019. Odoo 14 hasn’t been released yet for production. I will have a straight forward how to on installing the latest Odoo 13 in CentOS 7. <\/p>\n\n\n\n
Log in to your system and update<\/strong><\/p>\n\n\n\n First step would be to login to your system and then update the system using yum.<\/p>\n\n\n\n You may check the CentOS version from the redhat release file using the following:<\/p>\n\n\n\n It should show you something like the following if you <\/p>\n\n\n\n Now, you may try updating the system with yum<\/p>\n\n\n\n Once done, now install the EPEL repository as we need it to satisfy a couple of dependecies:<\/p>\n\n\n\n Install Python 3.6 packages and Odoo dependencies<\/strong><\/p>\n\n\n\n We need Python 3.6 at least to run Odoo 13. Odoo 12 had support for Python 3.5, unfortunately, Odoo 13 doesn’t. We will use ‘Software Collection (scl)’ repository to install and use Python 3.6. To find the available Python versions in SCL, you may check the following:<\/p>\n\n\n\n SCL Repository for Python<\/a><\/p>\n\n\n\n Now, to install Python 3.6 using SCL, we first need to install the SCL repository for Centos:<\/p>\n\n\n\n Once the SCL is loaded, now, you may install the python 3.6 using the following command:<\/p>\n\n\n\n Once the Python is installed, now we will install several tools and packages for Odoo dependencies with the following command:<\/p>\n\n\n\n Create Odoo User<\/strong><\/p>\n\n\n\n We now need to create a system user and group for Odoo and define a home directory to \/opt\/odoo<\/p>\n\n\n\n You may use any username here, but remember to create the same username for the PostgreSQL as well. <\/p>\n\n\n\n Install PostgreSQL<\/strong><\/p>\n\n\n\n CentOS base repository unfortunately, comes with Postgresql 9.2. But we want to use PostgreSQL 9.6 for our Odoo installation. You may check the available PostgreSQL for CentOS 7 using the following command:<\/p>\n\n\n\n As by default CentOS 7 does not provide the PostgreSQL 9.6, we would use PostgreSQL official repository to download and install the 9.6 version. <\/p>\n\n\n\n First, we install the Postgres Yum Repository using the following command:<\/p>\n\n\n\n Now, you may install PostgreSQL 9.6 and related required packages using the following command:<\/p>\n\n\n\n Now, we need to initialize the postgres database and start it. You may do that using the following:<\/p>\n\n\n\n Now you may enable Postgres to start when booting up using the systemctl enable command:<\/p>\n\n\n\n Now, we need to create a database user for our Odoo installation. You may do that using the following:<\/p>\n\n\n\n Note: If you have created a different user for Odoo installation other than ‘odoo’ than you should change the username here as well.<\/p>\n\n\n\n Install Wkhtmltopdf<\/strong><\/p>\n\n\n\n Wkhtmltopdf is a open source tool to make html in pdf format so that you may print pdf reports. This tool is used by Odoo and requires to be installed as dependency. CentOS 7 repository does not provide the latest version of this tool, and Odoo requires you to use the latest version. Hence, we require to download the latest version from the Wkhtmltopdf website and install it. To do that, you may first visit the page:<\/p>\n\n\n\n The page gives you the direct rpm download link for each version of CentOS\/Ubuntu\/Mac etc. Download the stable version for CentOS 7. At the time of writing, the URL for CentOS 7 x86_64 bit is the following:<\/p>\n\n\n\n You may install this using the following:<\/p>\n\n\n\n Install and Configure Odoo 13<\/strong><\/p>\n\n\n\n If you have come all through here, that means you are done with the all dependency installations before starting to download Odoo 13 source code. We will download Odoo 13 from it’s Github repo and use virtualenv to create an isolated python environment to install this python software. <\/p>\n\n\n\n First, login as odoo from root:<\/p>\n\n\n\n Clone the Odoo source code from Github repository:<\/p>\n\n\n\n This will bring the Odoo 13 branch from the Odoo repository and put it inside the folder \/opt\/odoo\/odoo13<\/p>\n\n\n\n Now, we need to enable software collections in order to access python binaries:<\/p>\n\n\n\n Then we need to create a virtual environment to complete the installation:<\/p>\n\n\n\n Now, you may activate the virtual environment you have just created:<\/p>\n\n\n\n Now, we upgrade the pip and install the wheel library:<\/p>\n\n\n\n Once done, now we can using pip3 to install all the required Python modules from the requirements.txt file:<\/p>\n\n\n\n Once the installation is complete, now we can deactivate the virtual environment and get back to the root user<\/p>\n\n\n\n If you think, you will create custom modules, you may now create it and give odoo the permission accordingly:<\/p>\n\n\n\n Now, we can fill up the odoo configuration file. First open the odoo.conf file:<\/p>\n\n\n\n You may paste the following inside:<\/p>\n\n\n\n Please do not forget to change the password ‘set_the_password_to_create_odoo_database’ with a new strong password. This would be used to create Odoo databases from the login screen.<\/p>\n\n\n\n Create the systemd service file and start Odoo 13<\/strong><\/p>\n\n\n\n Now, we will create a service file, to be able to start, stop and restart Odoo daemon. To do that, first create a service file using the following:<\/p>\n\n\n\n and paste the following:<\/p>\n\n\n\n Now, save the file and exit.<\/p>\n\n\n\n Now, you need to reload the systemd daemon to be able to read the latest changes you have made to services. To do that, run:<\/p>\n\n\n\n Finally, now we can start Odoo 13 instance using the following command:<\/p>\n\n\n\n If you are interested to check the status of the instance, you may do this:<\/p>\n\n\n\n It show green active running, if everything worked out. If you see no error, you may now enable Odoo to start during the boot:<\/p>\n\n\n\n If you would like to see the logs, you may either use the journal tools like the following:<\/p>\n\n\n\n or uncomment the following line to log the debugs in \/etc\/odoo.conf<\/p>\n\n\n\n After making any change to \/etc\/odoo.conf, do not forget the restart the Odoo13 instance using systemctl.<\/p>\n\n\n\n Test the Installation<\/strong><\/p>\n\n\n\n You may now test the installation using http:\/\/your_server_ip:8069. If everything worked, it should come up. If it doesn’t, you may try stopping your ‘firewalld’ to see if firewall is blocking the port or not:<\/p>\n\n\n\n At Mellowhost, we provide Odoo installation and configuration assistance for absolute free of charge. If you are willing to try out any of our VPS for Odoo, you may do so and talk with us through the Live chat or the ticket for Odoo assistance.<\/p>\n\n\n\n Furthermore, Good luck. <\/p>\n","protected":false},"excerpt":{"rendered":" Odoo is currently one of the most popular tool for business purposes.
