Question

我对myadminphp有疑问。我尝试进入管理区域但是当我使用网址时，页面是白色的。我在error.log上看过，我有这个错误

session_start（）：无法在第81行的/usr/share/phpmyadmin/libraries/session.inc.php中初始化存储模块：memcache（路径：/ var / lib / php5）

我不知道我能做什么！ Tx获取所有帮助

我的session.inc.php

Answer 1

通常意味着你在Apache config或php.ini

中的session.save_path参数中有一个错误的路径

尝试设置

ini_set("session.save_path", "/path/to/tmp");

在文件的开头。如果它有帮助，请编辑您的php.ini文件，否则尝试在某处找到它，可能在VirtualHost部分

Answer 2

请检查以下代码：

// optionally set session_save_path
$path = $GLOBALS['PMA_Config']->get('SessionSavePath');
if (!empty($path)) {
    session_save_path($path);
}

您可以尝试将其评论并再次测试（session_save_path（）的实现未在此处发布，我怀疑问题存在）。

Answer 3

好的，我找到了解决方案

 libraries/session.inc.php at line 79  // session.save_handler 
 ini_set('session.save_handler', 'files');

评论这一行，一切正常。

Answer 4

您只需要授予访问此目录的权限。

在Windows上，只需打开目录，系统就会要求您更改权限。
