Transfer and import files

The final pre-installation step for SaltStack Config is to download the installation files and send them to the Salt master node.

Before you start

This step is part of the pre-installation process. Before reading this page, ensure that you have first read:

• Installation overview
• Pre-installation planning
• Install or upgrade Salt

Download files

Download the installation files from Customer Connect. For assistance, contact your sales representative.

Transfer the files

Transfer the files to the Salt master node from which you are running the installation orchestration. Place the files in the root folder.

Verify the installation files

As a best practice, validate that the downloaded file was not altered after being created by VMware. You can validate the file by comparing the SHA-256 hash for your copy against the SHA-256 listed for that file.

To verify the installation files on RedHat or CentOS:

1. On the machine containing the files, open a terminal and navigate to the directory that contains the files.
2. If needed, use ls to list the exact file names.
3. Enter the following command, replacing the exact name of the file you want to verify:

   sha256sum file-name.zip

4. The previous command returns the SHA-256 for the file. Compare the output of this command to the SHA-256 listed for that file in Customer Connect.

Extract the files (optional)

Extracting the installation files is an optional step. It is only required if you downloaded the .zip version of the installer rather than the tarball.

Note:

If the machine doesn’t have this application or if it is air-gapped, download the tarball instead.

To extract the files on RedHat or CentOS:

1. In the terminal, install an application to extract the .zip file. For example:

   sudo yum install unzip

2. Once the unzip tool is installed, enter the following command, replacing the exact file name of the installation file:

   unzip SaltStack_Config-<version>_Installer.zip

Import the .asc keyfiles

You need to import the .asc keyfiles from the installer into the RPM packaging system. To import the keyfiles on the all the nodes involved in the installation:

1. Navigate to the ssc-installer directory.
2. To import the .asc keyfiles you extracted from the installer .zip file into the RPM packaging system, run the following command:

   sudo rpmkeys --import keys/*.asc

3. Repeat these steps for all nodes.

What to do next

Once you have downloaded, transferred, verified, and imported the installation files, you can begin the installation process.
