nginx连接处理方式说明

连接处理方式

nginx支持多种连接处理方式，具体使用哪一种由当前平台决定。如果当前平台支持多种方式，nginx会自动选择最佳的方式。然而，在有需要的情况下，可以通过use命令来指定连接处理方式。

以下为所支持的连接处理方式：

• select

  standard method. The supporting module is built automatically on platforms that lack more efficient methods. The –with-select_module and –without-select_module configuration parameters can be used to forcibly enable or disable the build of this module.

• poll

  standard method. The supporting module is built automatically on platforms that lack more efficient methods. The –with-poll_module and –without-poll_module configuration parameters can be used to forcibly enable or disable the build of this module.

• kqueue

  efficient method used on FreeBSD 4.1+, OpenBSD 2.9+, NetBSD 2.0, and Mac OS X.

• epoll

  efficient method used on Linux 2.6+.
  Some older distributions like SuSE 8.2 provide patches that add epoll support to 2.4 kernels.

• /dev/poll

  efficient method used on Solaris 7 11/99+, HP/UX 11.22+ (eventport), IRIX 6.5.15+, and Tru64 UNIX 5.1A+.

• eventport

  event ports, efficient method used on Solaris 10.
