mcrypt安装问题 [英] problem with mcrypt installation

问题描述

我已要求系统管理员在服务器上安装 mcrypt ，他们说一切正常。但是当我运行我的简单脚本，我得到这个。

I've asked the system admins to install mcrypt on the server, and they say everything is OK. But when I run my simple script I get this.

警告：mcrypt_get_iv_size（）[function.mcrypt-get-iv-size]模块初始化失败

Warning: mcrypt_get_iv_size() [function.mcrypt-get-iv-size]: Module initialization failed

来自此行：

$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,MCRYPT_MODE_ECB);

现在，从这段代码：

$algorithms = mcrypt_list_algorithms("/usr/local/bin/mcrypt");

foreach ($algorithms as $cipher) {
    echo "$cipher<br />\n";
} 

我得到：

警告：mcrypt_list_algorithms（）[function.mcrypt-list-algorithms]：在模块dir中找不到算法

Warning: mcrypt_list_algorithms() [function.mcrypt-list-algorithms]: No algorithms found in module dir

当我运行时：

$modes = mcrypt_list_modes("/usr/local/bin/mcrypt");

foreach ($modes as $mode) {
    echo "$mode <br />\n";
}

我得到：

警告：mcrypt_list_modes（）[function.mcrypt-list-modes]：在模块dir中找不到任何模式

Warning: mcrypt_list_modes() [function.mcrypt-list-modes]: No modes found in module dir

但是，运行此命令此命令

However, running this command this command

which mcrypt; mcrypt -v

产生：

/usr/local/bin/mcrypt

mcrypt 安装/配置是否正确？

Is mcrypt installed/configured correctly?

UPDATE：

我这样做：

whereis libmcrypt

。得到结果：

libmcrypt: /usr/local/lib/libmcrypt /usr/local/lib/libmcrypt.so /usr/local/lib/libmcrypt.la

我也改变了：

$modes = mcrypt_list_modes("/usr/local/bin/mcrypt");

到...

$modes = mcrypt_list_modes("/usr/local/lib/libmcrypt");
$algorithms = mcrypt_list_algorithms("/usr/local/lib/libmcrypt");

按照建议，但仍会收到错误：

As recommended, but still get the error:

警告：mcrypt_list_modes（）[function.mcrypt-list-modes]：

Warning: mcrypt_list_modes() [function.mcrypt-list-modes]: No modes found in module dir in

然后我进入我的CPanel中的文件管理器 / usr / local / lib / libmcrypt 。该目录存在，但其中没有文件...

Then I went into the file manager in my CPanel to /usr/local/lib/libmcrypt. The directory exists but it has no files in it...

这是文件管理器的打印屏幕。

Here is the print screen of the file manager.

谢谢。

推荐答案

尝试这样做，为您的mcrypt问题：

Try this for your mcrypt problem:

mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
sudo php5enmod mcrypt
sudo service apache2 restart

这是一个与mcrypt.ini文件位置有关的错误。

It's a bug with the location of the mcrypt.ini file.

我有同样的错误，我做了一个cp而不是一个mv

I had the same bug, I did a cp instead of a mv to be sure but it solved the problem.

对于PHP不工作，如果你得到phpmyadmin工作（即使有mcrypt错误），这意味着PHP正在工作（因为phpmyadmin使用PHP）。但在你的例子中

For PHP not working, if you get phpmyadmin working (even with the mcrypt error), it means PHP is working (because phpmyadmin uses PHP). But in your example

<? echo $row['details']; ?>

更改<？到<？php ，然后重试？
