Nginx主模塊

use

Syntax: use [ kqueue | rtsig | epoll | /dev/poll | select | poll | eventport ]

Default:

如果在./configure的時候指定了不止一種事件模型，那麼可以設置其中一個，以便告訴nginx使用哪種事件模型。默認情況下nginx會在./configure時找出最適合系統的事件模型。

你可以在 這裏 查看可用的事件模型以及如何在./configure時激活

 worker_connections

Syntax: worker_connections number

Default:

通過worker_connections和worker_proceses可以計算出maxclients：

max_clients = worker_processes * worker_connections

作爲反向代理，max_clients爲：

max_clients = worker_processes * worker_connections/4

debug_connection

Syntax: debug_connection [ip | CIDR]

Default: none

Since 0.3.54 this option support CIDR address format

This option gives you the ability to write debug log only for the clients of this IP/NET.

Several different directives are possible.

Example:

error_log /var/log/nginx/errors;
events {
  debug_connection   192.168.1.1;
}
