Common configuration methods for Nginx configuration file nginx.conf

Nginx use 两3 years, now often encounter a new user 1 some very basic question, I don't have time to reply, this afternoon take a little time, combined with the use of their experience, share the main configuration parameters that Nginx 1, and the content of the reference 1 some network, this article is by far the most complete Nginx Chinese illustrates the configuration parameters. More detailed module parameters please barometer: http: / / wiki nginx. org/Main

The theoretical value should be the maximum number of open files (the value of the system) ulimit -n ) and nginx Processes divide, but nginx Requests are not evenly distributed, so it is recommended that the ulimit -n The value of the keep 1 Cause.
