nginx配置文件

前面一篇，我们介绍nginx的安装，这篇介绍下nginx配置文件

 

功能介绍，可以参考这篇博文 http://www.cnblogs.com/skynet/p/4146083.html

可以简单理解：

nginx可以用于stream模块 (tcp)，或是http模块反向代理。

当使用http代理的时候，就会有server 节点（可以有多个server），配置不同域名。

在server下，我们常常基于不同的功能模块划分url， 那么就有location节点（也可以有多个），配置不同的匹配规则

当请求到达location后，这里我们一般会区分两种情况，

一种如果是静态资源的话直接访问本地文件，

另外一种就是转接到相应的解析器上，比如http代理就是 proxy_pass  upstream_name, 常用php代理则是 proxy_fastcgi upstream_name

 

这里我贴出了一个实例配置文件，其中每一项设置都是基于理由的

user  www;
worker_processes  auto;  　　＃worker数应该等于cpu核数
worker_cpu_affinity auto;　　＃每个worker绑定到一个cpu核上

worker_rlimit_nofile 102400;　　＃worker最大可以打开文件数

error_log  /var/log/nginx/error.log error;　　＃nginx错误日志路径
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    use epoll;　　＃使用epoll组件处理文件句柄
    accept_mutex off;
    worker_connections  102400;　　＃worker最大连接数
}
