Oneself to learn to do a kind of forum website to be actually put into operation and maintenance, should learn some what skill?

Before it was yourself and another front-end development of a similar forum site, did not use discuz that framework, written in the framework of PHP. Now the teacher is going to put it into operation and to provide me with complete maintenance and documentation. But I did not join the security guard before, and I am not quite sure how the server should be managed.
I would like to ask you what books I should read, to learn what aspects of the book. I have read some books, but still too theory, for the actual site to manage the server, Linux user responsibilities should be specific how to manage, the database management did not say. I hope you will provide some guidance and advice.

As far as I know, I hope other people can provide a better answer.

1 environment
Operating environment, including system, configuration, database version used, PHP version, and possibly some other dependencies
2 deployment
Specific deployment steps, documentation, common problem solving methods during deployment, and more.
It is best to be able to provide startup scripts, configure self-booting
3 operation and Maintenance
Includes server security, monitoring (CPU, memory, bandwidth, disk capacity, etc.)
Multi-node configuration
4 Data security
Data backup, recovery plan, etc. if necessary
5 optimization
It's about what's wrong and what's being solved.
