mcrypt php phpmyadmin load exist Open hint method hour solve question

今天在打开phpmyadmin时提示:phpMyAdmin出现无法载入 mcrypt 扩展,请检查PHP配置,下面我来给大家一起来看看无法载入 mcrypt问题解决办法。


你打开phpmyadmin就会提示 :无法载入 mcrypt 扩展,请检查 PHP 配置错误

出现以下几种情况后可能会造成运行phpmyadmin程序 提示“无法载入 mcrypt 扩展,
请检查 PHP 配置”的 错误提示


windows解决办法

1、没有正确安装Mysql数据库,在系统服务中Mysql相关的服务没有启动   (请查看正确安装Mysql的方法)

2、在系统的 system32(C:windowssystem32) 目录下缺少 libmcrypt.dll文件,解决方法是找到php目录下的libmcrypt.dll,并将libmcrypt.dll复制到C:windows system32目录中,然后重新启动Web服务。

3、在C:windows目录下的php.ini文件中,没有将“;extension=php_mcrypt.dll”中的前面一个“;”去 掉,所以不能使用相应功能,解决方法是打开php.ini文件

 代码如下 复制代码

找到

;extension=php_mcrypt.dll

改成

extension=php_mcrypt.dll    //去掉前面的;使之生效


linux系统下解决办法

一:无法加载 mcrypt扩展,请检查您的 PHP 配置

 

 代码如下 复制代码

 
sudo  apt-get install libmcrypt4 php5-mcrypt    //安装libmcrypt

  
sudo /etc/init.d/apache2  restart     //重启apache

二:配置文件现在需要一个短语密码


1、用编辑器打开目录phpmyadmin/libraries中的config.default.php文件

2、查找下面这行:$cfg['blowfish_secret'] = ‘这里就是需要的短语密码’;(短语密码请随意填写)

会出现这个问题,是在配置phpmyadmin填写认证方法时,即下面这行:

$cfg['Servers'][$i]['auth_type'] = ‘cookie’;

在此有四种模式可供选择,cookie,http,HTTP,config

config方式即输入phpmyadmin的访问网址即可直接进入,无需输入用户名和密码,是不安全的,不推荐使用。

当该项设置为cookie,http或HTTP时,登录phpmyadmin需要数据用户名和密码进行验证,,具体如下:

PHP安装模式为Apache,可以使用http和cookie;

PHP安装模式为CGI,可以使用cookie
