Ansible can be used to do something on a collection of target computers. For example, you could query each computer to determine the operating system installed on each computer, or you could install software on the target computers.
Ansible Tower requires at least 2 GB of RAM, but recommends at least 4 GB. Use the free command to determine how much memory your system has. In this example, the system has less than 2 GB of memory, which will cause the install the fail. If your server does not have enought free memory, add memory to the server before installing Ansible Tower.
