CI 在nginx中出现404错误的解决方式

 if (!-e $request_filename) {
      rewrite ^.*$ /index.php last;
    }
//出现的问题 用这个解决了，

NGINX 默认不支持 PATH_INFO 模式，需要修改NGINX配置 让NGINX 来解析 index.php/controller/f 这种模式 具体配置：

#CI
server {
        listen      80;
        server_name www.ci.com;
        index       index.php index.html index.htm;
        root        "/servers/apps/CI";
      location ~ \.php{
       fastcgi_pass 127.0.0.1:9000;
           fastcgi_index index.php;
            ##########################################pathinfo 模式
            set $path_info "";
            set $real_script_name $fastcgi_script_name;
            if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$"){
                 set $real_script_name $1;
                 set $path_info $2;
            }
            include fastcgi.conf;
            fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
            fastcgi_param SCRIPT_NAME $real_script_name;
            fastcgi_param PATH_INFO $path_info;
