Nginx 虚拟主机配置笔记

Nginx 虚拟主机在配置的时候，php需要配置cgi来做相应的解析，其中有个参数fastcgi_param，原先设置为

fastcgi_param  SCRIPT_FILENAME  /usr/local/Cellar/nginx/1.12.0_1/html$fastcgi_script_name; 

导致虚拟主机在解析php县骨干文件的时候都是去www的根目录去进行定位，导致出现404的问题，后来修改为：

fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;

解决了这个问题。

完整配置文件如下：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}

    #                  '"$http_user_agent" "$http_x_forwarded_for"';
