Using Odoo to Build an ERP System (Historical Version)

Scenarios

Odoo is an open-source ERP/CRM software that integrates a comprehensive suite of applications for managing all aspects of your business, including procurement, inventory, finance and accounting, marketing, manufacturing, human resources management, service support, e-commerce, and website building, achieving fully automated service processes. FlexusL provides an Odoo application image running on Ubuntu 24.04 and deployed with Docker. The image comes pre-installed with Nginx, pgAdmin, and Docker. This section describes how to use Odoo to build an ERP system.

This practice applies to FlexusL instances with an Odoo application image purchased before August 28, 2026. For best practices of the new image version, see Using Odoo to Build an ERP System.

To update the image version, change the OS. This operation will clear the data on the original system disk. Back up the data in advance.

Prerequisites

You have purchased a FlexusL instance with a legacy Odoo application image.

Step 1: Configure Security Groups

Add inbound security group rules to ensure that the application preinstalled in the image can be accessed.

1. Log in to the FlexusL console and click the target resource card or instance name to go to the instance details page.
2. In the navigation pane on the left, choose Cloud Servers and click the target server name to view its details.

   

3. On the Security Groups tab, click Add Rule to add the rules listed in the following table.

   The following only lists common rules. You can add more rules as needed.

   Table 1 Security group rules

   Priority	Action	Type	Protocol & Port	Source	Description
   1	Allow	IPv4	TCP: 80	0.0.0.0/0	Specifies the internal forwarding port of application images
   1	Allow	IPv4	TCP: 9001	0.0.0.0/0	Allows external access to the application dashboard.

Step 2: Reset the Password and Log In to the FlexusL Instance

This section describes how to log in to a FlexusL instance. A FlexusL instance does not have an initial password. After creating a FlexusL instance, set a password for the FlexusL instance before logging in to it.

1. In the Image area on the Overview page of the FlexusL console, click Access to go to the application dashboard and check whether the application has been up and running. If yes, go to the next step.
   

   Wait for several minutes until the application is up and running. Then, you can perform operations such as restarting or stopping the instance, or resetting the password. Otherwise, the initial password may become invalid and you cannot log in to the application dashboard.

   After the application is started, the initialization wizard page of the dashboard is displayed.

   If the dashboard is not properly displayed, check the following causes:

   • The port for accessing the dashboard is not enabled. Enable it as needed.
   • The dashboard is being started. Try again later.
2. Locate the resource card and choose > Reset Password. Alternatively, in the list view, click Reset Password in the Operation column to reset the password for the FlexusL instance.

   A FlexusL instance does not have an initial password. Set a password for the FlexusL instance before logging in to it. For details, see Resetting the Password for a FlexusL Instance.

3. Locate the resource card and click Remote Login. Alternatively, in the list view, click Remote Login in the Operation column. In the displayed dialog box, click VNC Login and enter the username and password as prompted to log in to the FlexusL instance. For more login methods, see Login Modes.

   The username is root, and the password is the one you set in the previous step.

   

Step 3: Initialize Odoo

Application images use code-based Ubuntu. They provide graphical user interfaces to make your operations easier. You need to initialize the application dashboard upon the first login. Then you can directly log in to the dashboard from the FlexusL console afterwards.

1. On the Overview page, click Access in the Dashboard field in the Image area.

   

   

   If the dashboard is not properly displayed, check the following causes:

   • The port for accessing the dashboard is not enabled. Enable it as needed.
   • The dashboard is being started. Try again later.
2. Configure the parameters and click Create database.

   If you have had a backup database on your local device, click or restore a database.
