3 year Linux Sysadmin, here my 2c: Buy ASAP both "UNIX and Linux System Administration Handbook" and "Practice of System and Network Administration". UNIX and Linux System Administration Handbook -> Will give you the necessary tech skills and concepts. This is a sysadmin bootcamp. Practice of System and Network Administration -> Will show you how to the job right. This is more like 'how to manage' an operations team. Each book is massive and will take you 1 month to read. I suggest you start with UNIX and Linux System Administration Handbook.
