Troubleshoot MySQL configuration with a MySQLTuner script
MySQLTuner is an original Perl® script written by Rackspace that executes a series of Structured Query Language (SQL®) queries to identify some common configuration issues with MySQL®. By using the results, you can make adjustments to increase performance and stability.
Always back up your configuration files before testing the optimizations. You should not perform optimizations unless you fully understand (or have researched) the implication of changing the settings.
Use the following steps to run MySQLTuner:
Ensure that your ~/.my.cnf file is properly configured. By using this file, you can configure MySQLTuner to automatically connect to the remote database (client). Enter the following values:
user=<userName> password=<password> host=<cloudDBHostname>
Download the mysqltuner.pl script from https://github.com/major/MySQLTuner-perl.
Run the script by using Perl.
