一、准备工作

1. 已经安装了tengine

二、conf文件的默认配置

conf文件的默认配置

　　1、worker_processes设置

　　

 

 　　一般和CPU内核数相绑定，这样一个CPU对应一个进程，不需要分片消耗性能。

　　详细的参数配置可参考nginx worker_processes 配置 - aaron_agu - 博客园 (cnblogs.com)

　　2、worker_connections配置

　　

　　表示1个worker建立2048个线程，也就是目前能承受4*2048个并发量。

　　worker_connections与网络I/O和磁盘I/O有关。

　　与服务器内核每个进程能够打开多少个文件有关。

　　

 

 　　这个指的是，这台服务器允许打开的文件句柄个数。

　　也就是worker_processes * worker_connections < file-max
