要目录下的.htaccess

config/database.php也是看了又看肯定是没错的了,oncache也关了。
文件名和class名也统统是小写的了,今天上去一看提示无法连接数据库
麻烦帮我看看,谢谢!

建议 hostname 使用 localhost。

另外服务器上数据库是否安装成功?是否启动?
你可以在 cmd / termanal (进你的网站直接出来phpinfo,是Linux系统) 里面输入:

<code class="lang-bash">mysql -uroot -pabc136268
</code>
Copy after login

测试用这个用户名和密码能不能连接上。

您倒是贴个配置文件,再贴个 model 连接数据库的代码呀……

姑且一猜:

在你的 database.php 里,是不是类似这样的?

<code class="lang-php">$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
...
</code>
Copy after login

然后在你的 model 文件里是不是这样的?

<code class="lang-php">class Some_model extends CI_Model {

function __construct() {

    parent::__construct();

    $this->load->database();    // 注意这里
}
</code>
Copy after login

看上面的注释,默认的 database group 叫做 default,所以 $this->load->database() 不传递参数就会读取默认值。如果你显式指明了组名称,比如 $this->load->database('groupname'),那么你就要对比一下看看 database.php 里组名写的是否正确了。

这是在没有代码的前提下猜的,比较常见的错误,具体如何还是要看你代码的。
