CI框架在NGINX下的伪静态规则修改：

1、location

location / {
if (!-e $request_filename) {
rewrite ^/(.*)$ /index.php/$1 last;
break;
}
}

或

location / {

       try_files $uri $uri/ /index.php?$uri&$args;

}

2、location ~ [^/]\.php(/|$)

location ~ [^/]\.php(/|$) {
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;

#增加以下两行
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;

include fastcgi.conf;
}

Apache配置方法：

1、修改httpd.conf,开启rewrite模块

LoadModule rewrite_module modules/mod_rewrite.so

2、将站点配置文件中

AllowOverride None 修改为 AllowOverride All 

3、在站点根目录添加.htaccess文件，内容如下：

RewriteEngine on
RewriteCond $1 !^(index\.php|images|public|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
