Has this only started happening whilst working previously? Or are you trying something new?

Take a look at what is already installed

yum list ¦grep php

yum list ¦grep mysql

note the ¦grep is the broken pipe character and word grep

If php and mysql were installed via yum packages then they should be listed there. But it could be the case they were compiled manually.
