Which two preparatory tasks are required prior to installing an AppDynamics Controller on Linux? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: D, E

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 runyum 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 runningdf -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.tmpdirparameter 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.Reference:Prepare Linux for the Controller,Install the Controller on Linux, and [Controller System Requirements] in the AppDynamics documentation.

Yeah, installing JRE and making sure there's enough temporary space makes sense.

E is definitely important too. You don't want your installation to fail because you didn't have enough temporary space.

Haha, they're really trying to trick us with that MySQL port option. Nice try, but I'm not falling for that one!

Yes, that's correct. We also need to verify that we have enough temporary space available.

I'm a bit confused about the MySQL port requirement. Isn't the AppDynamics Controller its own separate application? Why would we need to open that port?

Opening MySQL port is for communication between Controller and MySQL database.

A and D seem like the obvious choices here. You need to have the JRE installed and the libaio library to run the AppDynamics Controller on Linux.
