The events module contains all the settings for handling connections in nginx.

The common configuration items are as follows

Events {

Use epoll

Worker_connections 20000

}

detailed description

Use epoll

# use epoll's Iamp O model (it's worth noting that if you don't know which polling method Nginx should use, it will choose the one that works best for your operating system)

Supplementary note:

Similar to apache, nginx has different event models for different operating systems.

A) Standard event model

Select and poll belong to the standard event model. If there is no more effective method in the current system, nginx will choose select or poll.

B) efficient event model

Kqueue: used in FreeBSD 4.1, OpenBSD 2.9, NetBSD 2.0 and MacOS X. Using kqueue on MacOS X systems with dual processors may cause the kernel to crash.

Epoll: used in Linux kernel version 2.6 and later.

/ dev/poll: used for Solaris 7 11 Universe 99, HP/UX 11.22 + (eventport), IRIX 6.5.15 + and Tru64 UNIX 5.1A +.

Eventport: used in Solaris 10. To prevent kernel crashes, it is necessary to install security patches

To check the linux version number, you can use the cat / proc/version command

Cat / proc/version

The output is as follows

Linux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)) # 1 SMP Fri Nov 22 03:15:09 UTC 2013

Worker_connections 2000

# maximum number of connections to worker processes theoretically the maximum number of connections per nginx server is the number of processes started by worker_processes*worker_connections worker_processes for us in main
