As you can see above, operation and maintenance is a job that combines multiple IT skills. You need to know something about system-> network-> storage-> protocol-> requirements-> development-> test-> security and other links.

But you need to be familiar with or even proficient in some aspects, such as systems (familiar with the use of basic operating systems, * nix,windows.), protocols, system development (automatic operation and maintenance related development, large-scale cluster tool development, management), general applications (such as lvs, ha, web server, db, middleware, storage, etc.), network, IDC topology architecture. Linux operation and maintenance learning route, what knowledge does linux operation and maintenance need to master? A good Linux operation and maintenance needs to master a lot of knowledge.
