The judge threw the book at Chidi -- who went after Seacrest outside of an Orange County hospital back in September ... armed with a knife.

Chidi then showed up the E! building where Seacrest shoots his daily TV show a month later in violation of a restraining order ... also armed with a knife.

In addition to the sentence, the judge ordered Chidi to stay clear of Ryan for 10 years.  By then, Ryan will own L.A. and can keep anyone out himself.
