在Joomla上出现错误：无法读取会话数据和应用程序实例化错误

Question

我正在尝试在本地主机上运行Joomla网站，但出现以下错误：

警告：session_start（）：无法读取会话数据：第258行上的C：\\ xampp \\ htdocs \\ Joomla_3 \\ libraries \\ joomla \\ session \\ handler \\ native.php中的用户（路径：C：\\ xampp \\ tmp）错误页面：应用程序实例化错误：无法启动会话

我试图通过Internet找到解决方案，并对“ configuration.php”文件进行了一些更改，但是仍然一次又一次出现相同的错误：这是我的配置。 文件：

这是index.php文件：

<?php
    define('JOOMLA_MINIMUM_PHP', '5.3.10');

if (version_compare(PHP_VERSION, JOOMLA_MINIMUM_PHP, '<'))
{
    die('Your host needs to use PHP ' . JOOMLA_MINIMUM_PHP . ' or higher to run this version of Joomla!');
}

// Saves the start time and memory usage.
$startTime = microtime(1);
$startMem  = memory_get_usage();

/**
 * Constant that is checked in included files to prevent direct access.
 * define() is used in the installation folder rather than "const" to not error for PHP 5.2 and lower
 */
define('_JEXEC', 1);

if (file_exists(__DIR__ . '/defines.php'))
{
    include_once __DIR__ . '/defines.php';
}

if (!defined('_JDEFINES'))
{
    define('JPATH_BASE', __DIR__);
    require_once JPATH_BASE . '/includes/defines.php';
}

require_once JPATH_BASE . '/includes/framework.php';

// Set profiler start time and memory usage and mark afterLoad in the profiler.
JDEBUG ? $_PROFILER->setStart($startTime, $startMem)->mark('afterLoad') : null;

// Instantiate the application.
$app = JFactory::getApplication('site');

// Execute the application.
$app->execute();

我想知道我的网站不在本地主机上运行的原因吗？ 感谢帮助。

Answer 1

如我所见，配置$ host是正确的，因此可能是不同的原因。 但是对我来说解决方案是删除$host变量中configuration.php中的:符号。

Answer 2

将mysql文件夹移动到另一个挂载后，我遇到了相同的错误，我不得不将configuration.php中的$ host从“ localhost”更改为“ 127.0.0.1”，从而解决了该问题。
