Server Admin Newbie Book Recommendation?

Hey guys, recently at my job I’ve had to deal with a lot more server admin stuff than i typically do, can anybody recommend some good books that cover webserver administration? Ideally it would cover topics like Plesk, DNS zone files, Apache, creating new user accounts and installing new software through shell, that sort of thing. I am mildly experienced in this stuff but a really good resource book would help a lot. thanks all in advance for your recommendations.
