Contents
General
- HTTP and reverse proxy server, mail proxy server
- Employs event-based model and OS-dependent mechanisms to efficiently distribute requests among worker processes
- docs
- Beginner's Guide
- Alphabetical List of Directives
- Master process - read and evaluate configuration, and maintain worker processes
- Worker processes - do actual processing of requests; # is defined in the configuration file
Configuration File
- Comments start with hash #
Structure
- nginx modules controlled by directives
- two types of directives: simple and block directives
- simple directive - directive name, followed by params, ends with a semicolon
- block directives ("context") - same as simple, but instead of semicolon ends with curly braces
Contexts
events
- top-level "main" context, cannot be within another
http
- top-level "main" context, cannot be within another
server
- Within http context only
- Can have multiple server names
- Once nginx decides which server will process the request, it tests the URI specified in the request's header against the location directives defined in the server block.
- Order of precedence is longest to shortest prefix, so location '/' will match last.
location
- Within server context only
- Performs mapping of URL to route to static files on server, or proxy, etc.
location URIPREFIXARG { root /path/to/static/files;}
