I am moving an existing Percona instance to a new server running RHEL 7.2. The existing server is Centos 6.5 and there are no warning there. The install ran without any problems.
I used the yum repo install described here: https://www.percona.com/doc/percona-server/5.7/installation/yum_repo.html
I used the Webtatic repo to install PHP 5.6 as described here: https://webtatic.com/packages/php56
So the problem is fairly minor, but one I don’t like to see on a production server. When ever a db connection is made I get this warning:
I do not get the warning when using PDO.
I never like turning off warnings and I don’t like seeing them, so I’d like to fix this. Any ideas?
