A Dockerfile can only have one CMD instruction. Only the last will run and others will be ignored.

What most people do is run one service per container. So you would have a httpd container and a mariadb container communicating with each other through a shared network.

If you insist on running both in the same container, you have to start both services using a single CMD instruction.
