In this post, I am showing the installation process of MySQL Tuner in Ubuntu 16.04.
MySQL Tuner is a useful tool that will connect to a running MySQL instance and offer suggestions for how it can be configured for your workload.
You can use this tool for running production server as well, and it will give you different types of Performance Metrics and Server statistics like about the Storage, Security, Performance Parameters, Cache Parameters, InnoDB Settings, MyISAM Settings and more.
Install MySQL Tuner in Ubuntu 16.04:

sudo apt-get install mysqltuner |
Execute MySQL Tuner:

Here, I am also sharing the sample result of my test server on which I installed and executed MySQL Tuner.
