How to Upgrade MySQL 5.6 to 5.7 in Linux | MySQL Version Upgrade in Linux

From this article you will know how to upgrade MySQL 5.6 to 5.7 in Linux. Please go through the recommendation once before starting the actual database upgrade.

  • If your MySQL installation contains a large amount of data that might take a long time to convert after an in-place upgrade, it may be useful to create a test instance for assessing the conversions that are required and the work involved to perform them. To create a test instance, make a copy of your MySQL instance that contains the MySQL database and other databases without the data. Run the upgrade procedure on the test instance to assess the work involved to perform the actual data conversion.
  • Rebuilding and reinstalling MySQL language interfaces is recommended when you install or upgrade to a new release of MySQL. This applies to MySQL interfaces such as PHP MySQL extensions and the Perl DBD::mysql module.

MySQL Software Download and Installation

To read more about this section please read my detailed MySQL Installation Document. Here I am describing these steps in short.
