Mysql basic packages will be installed by default when installing the RHEL, If you dont want the mysql, you can customize installation according to your requirement..
Some people will select the default installation, thereby this mysql packages also installed along with OS packages.
Thanks for your reply. Is it possible to remove the package installed by default if it is found that it is of no use?
There are few observations with the 2 links I posted, in the link,
it is difficult to figure out which update to apply as it is giving a whole lot of product versions and in the other link, it is giving reference mainly to one particular version of the product, MySQL Community Server 5.6.14 which may not be the version to apply.
I was wondering how to upgrade from these links if these links are not showing something specific.
Request you to please revert.
