Install c4

This article explains how to install Exasol Deployment Tool (c4) and AWS CLI.

Exasol Deployment Tool (c4) is a command line tool that is used to create, configure, and manage Exasol deployments on all supported platforms. You can also access the ConfD and EXAsupport administration interfaces through c4.

For information about the latest release of Exasol Deployment Tool (c4), see c4 Release Notes.

AWS Command Line Interface v2 (AWS CLI) provides a tool to manage your AWS services directly from the command line. AWS CLI must be installed on the computer that is used for creating an Exasol deployment on AWS.

Prerequisites

There are no prerequisites for this procedure.

Download and install AWS CLI

For information about how to install AWS CLI on Linux, refer to Installing or updating the latest version of the AWS CLI on the AWS documentation website.

Download and install c4

Download c4 using a browser

  1. Download the c4 binary from the Exasol Download Portal.

  2. In the directory where you downloaded c4, run the following command to make c4 executable for all users:

    chmod +x c4

Download c4 using Linux command line

To download the latest version of c4 using the Linux command line, you can use wget. The following command will download the c4 binary and set the necessary permissions in a single operation. The -O option will overwrite any existing version of the c4 executable in the same directory. 

wget https://x-up.s3.amazonaws.com/releases/c4/linux/x86_64/<version>/c4 -O c4 && chmod +x c4

Replace <version> with the latest c4 version, for example, 4.16.0.

For information about the latest release of Exasol Deployment Tool (c4), see c4 Release Notes.

You must use chmod +x c4 to make c4 executable for all users, otherwise the application will not be able to run the installation.

How to update c4

To update c4, download the latest version and replace the existing binary. If you are using the command line to download c4, make sure that you include the -O option (overwrite) in the command.

Replacing the c4 binary will not affect any existing configuration files.

Next steps

Once you have installed c4 and AWS CLI on your system, the next step is to create a configuration file for c4 and set up authentication for deploying Exasol on AWS.
