Can we add MySQL Indexes without the server and client?

I was given access to a cluster today along with a front-end. The person who gave me access tells me I cannot start anything开发者_JAVA百科 on the front-end and that I should submit everything as a job. Now I have no idea what that means but I'm thinking that I am not supposed to start MySQL on the front-end. If that is the case, how can I even use the database?

Is there a way I can add indexes without using the client-server? Or is it even possible to use a database in a cluster setup where I can only submit jobs?

I am guessing the person means that the client is actually executed as a "job". you might want to find out how they program the cluster.
