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.

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

Download the c4 binary from the Exasol Download Portal.
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), visit the Exasol Download Portal.

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

Updating c4

The c4 binary is automatically updated when you update the Exasol database. There is normally no need to manually update c4.

If you want to replace a currently installed version of c4, download the version that is compatible with your database version from the Exasol Download Portal and overwrite the existing binary.
