数据库访问 失败 没有日志

shopping

我用3.0的版本  在我本地机器上用xampp的环境能否正常访问， 上传到服务器  服务器是centos  单独安装的apache mysql  php  一涉及到数据库访问的时候就是失败了
$sql = "SELECT customer_id, name, zjm FROM customer";
$this->load->database();
$query = $this->db->query($sql);

load是正常的，执行query就停止了   日志信息里面是

请问是怎么回事呢？

把$this->load->database();注释掉试试

注释掉之后 就报的db没有找到的错误

这个日志记录没有错误信息，你看一下MySQL的日志

报什么错？
