#The maximum number of file descriptors opened by an nginx process. The theoretical value should be the maximum number of open files (system value ulimit -n) divided by the number of nginx processes. However, nginx allocation requests are not uniform, so it is recommended to use ulimit - The value of n remains consistent.

The above introduces the Chinese detailed explanation of the Nginx configuration file nginxconf, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
