📝 How to Install Chef Server on Ubuntu

Before we get started, there are a few prerequisites you need to have in place:

• A clean installation of Ubuntu 18.04 or later
• Superuser access (you can use the sudo command)
• A stable internet connection
• The ability to follow instructions and troubleshoot errors

Step 1: Add Chef’s Repository

The first step is to add Chef’s repository to your system. Open the terminal and enter the following commands:

Note: Make sure to replace VERSION with the latest version number of Chef Server.

Step 2: Configure Chef Server

Once the package is installed, you need to configure Chef Server. Run the following command:

sudo chef-server-ctl reconfigure

This command will take a few minutes to complete, and it will configure all the necessary components of Chef Server, including PostgreSQL, RabbitMQ, and Nginx.

Step 3: Create Admin User

Now that Chef Server is configured, you need to create an admin user. Run the following command:

sudo chef-server-ctl user-create USERNAME FIRST_NAME LAST_NAME EMAIL PASSWORD --filename FILENAME

Make sure to replace the capitalized words with your own information. This command will create an admin user and generate a private key file that you can use to authenticate with Chef Server.

Step 4: Create Organization

The last step is to create an organization. Run the following command:

sudo chef-server-ctl org-create SHORT_NAME 'FULL_NAME' --association_user USERNAME --filename ORG-validator.pem

Again, make sure to replace the capitalized words with your own information. This command will create an organization and generate a validation key file that you can use to authenticate nodes with Chef Server.
