Install c4

This section explains how to install Exasol Deployment Tool (c4) on AWS.

Prerequisites

AMI running Ubuntu 20.04 LTS or 22.04 LTS with jq JSON processor installed

Download and Install c4

Download 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

    If you download c4 from the 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.

Download using Linux command line

To download the latest version of c4 using the command line, run the following command in a Linux terminal. This command will download the 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/latest/c4 -O c4 && chmod +x c4

Update c4

To update c4, perform the installation procedure again as described above, overwriting the existing version. There is no separate update procedure. Configuration files will be left unaltered.

Verify Installation

To verify that c4 has been correctly installed and is accessible, use c4 --version or c4 -v. 

$ c4 --version
c4 version 0.4.12

Next Steps

Once c4 has been installed you must create a configuration file and set the necessary permissions. For more information, see Configure c4 for AWS.
