错误500安装Magento

我正在我的服务器上安装Magento 2.0.0版 . 我甚至没有配置就得到500错误 . 尝试各种解决方案得不到积极响应 . 应用检查和清理文件并接收以下消息：

检查：

Your server does not meet the following requirements in order to install Magento.
The following requirements failed, please contact your hosting provider in order to receive assistance with meeting the system requirements for Magento:

You need MySQL 4.1.20 (or greater)

The following requirements were successfully met:
You have PHP 5.2.0 (or greater)
Safe Mode is off
You have the curl extension
You have the dom extension
You have the gd extension
You have the hash extension
You have the iconv extension
You have the mcrypt extension
You have the pcre extension
You have the pdo extension

清理 ：

----------------------- CLEANUP START -------------------------

Setting all file permissions to 644

在检查文件中，它说我的服务器上没有该版本的MySQL . 添加以下代码以查看我的版本，这就是答案：

echo "<h2>Exact Version PHP & MySQL: </h2>";
printf("PHP version: %s\n", PHP_VERSION); 
$mysql = mysqli_connect('localhost', 'root', 'example'); 
#$mysql = mysqli_connect('localhost', 'root', ''); 
## Test the MySQL connection 
if (mysqli_connect_errno()) {
   printf("</br> Connection failed: %s\n", mysqli_connect_error());
   exit();
}
## Print the MySQL server version 
printf("</br> MySQL server version: %s\n",    mysqli_get_server_info($mysql)); 
##Close the MySQL connection 
mysqli_close($mysql);

结果：

Exact Version PHP & MySQL:

PHP version: 5.5.30-1~dotdeb+7.1 
MySQL server version: 5.6.15

EDIT
