Explanation:

Before installing an AppDynamics Controller on Linux, you need to perform some preparatory tasks to ensure the system meets the requirements and the installation runs smoothly.

Two of these tasks are:

Install libaio on the host machine if it does not already have it installed. This library facilitates asynchronous I/O operations on the system, which are required by the Controller. You can use the package manager of your Linux distribution to install libaio, such as yum or apt-get. For example, on CentOS, you can run yum install libaio1.

Verify that you have enough temporary (tmp) space available on the system, at least 1 GB. The Controller installation uses the tmp space to extract and install the software components. You can check the tmp space by running df -h /tmp2. If the tmp space is insufficient, you can either free up some space by deleting unnecessary files, or specify a different temporary directory for the installation by passing the -Djava.io.tmpdir parameter to the installer3.

Other preparatory tasks include verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the file descriptor limit2.
