codeigniter在nginx安装配置及URL重写

　　产品需要使用ci框架能有优雅的uri方式，希望产品的服务器中间件有强悍的性能选择，我把ci的项目放到nginx上并去除index.php;

步骤一

　　

//在application/config.config.php
$config['uri_protocol'] = "PATH_INFO";

　步骤二

　　修改nginx.conf

server {
        listen       80;
        listen [::]:80 ipv6only=on;
        server_name  www.example.com;
 
        root   /data/www/www.example.com;
        index index.php  index.html index.htm;
 
        location / {
                # 这里使用try_files进行url重写，不用rewrite了。
                try_files $uri $uri/ /index.php?$query_string;
        }
 
        location ~ \.php($|/) {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            fastcgi_param   PATH_INFO $fastcgi_path_info;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
 
        location ~ /\.ht {
                deny  all;
        }
}
