安装php7.2-mcrypt时出现的问题

Question

当我试图从PHP7.2.X版本加载mcrypt扩展模块时。
因此我尝试使用与当前PHP版本兼容的PECL库，以便安装并遵循以下链接：在安装期间在PHP7.2上安装mcrypt！

以下是在终端上执行某些命令后获得的结果。

因为我得到的错误类型是pecl7.2-sp:command not found

从留档部分可以清楚地看到，它已经被弃用了，从安全的角度来看，它将不再可用——从那以后，从PHP 7.2的发布版本来看。X向前的。

但是项目的一些成员需要这些依赖项，以便在必要时执行所需的功能。我需要如何解决上述问题？

TL； DR：

我从投票中得到了很多对发布答案的回应。答案需要根据操作系统架构级别进行分类。由于我使用共享服务器托管有多个项目驻留在它

正如我在链接中已经提到的，在PHP 7.2上安装mcrypt扩展，由服务器试点社区。这些人告诉我们，一个更新版本的pcl-7.2可以在PHP-7.2上安装mcrypt。不幸的是，它以pepl7.2-sp：命令未从已执行的命令中找到结束。后来网站页面得到了更新，所以那里的命令与执行时尝试的命令不匹配。

最后，无论哪种解决方案适合您的操作系统架构级别，只管去做吧！。

如果以下方法无法解决根本原因。
或者，您可以选择默认支持mcrypt扩展的PHP7.1.X版本

Answer 1

@praneth-nidarsan已经覆盖了大部分台阶，除了一些：

• 检查是否已安装（或安装）梨：

apt-get安装php-pear

• 如果尚未安装，请安装php7.2-dev，以避免出现错误：

sh： phpize：未找到

错误：`phpize'失败

$sudo apt get安装php7.2-dev

• 使用pecl安装mcrypt：

$sudo pecl安装mcrypt-1.0.1

• 在php.ini的配置文件中添加extence扩展名=mcrypt.so；如果你不知道它在哪里，请使用：

$sudo php-i|grep'配置文件'

Answer 2

加密PECL扩展

 sudo apt-get -y install gcc make autoconf libc-dev pkg-config
 sudo apt-get -y install libmcrypt-dev
 sudo pecl install mcrypt-1.0.1

当显示提示时

 libmcrypt prefix? [autodetect] :

按[Enter]自动检测。

在成功安装mcrypt-trought-pecl之后，应该将mcrypt.so扩展添加到php.ini。

输出将如下所示：

...
Build process completed successfully
Installing '/usr/lib/php/20170718/mcrypt.so'    ---->   this is our path to mcrypt extension lib
install ok: channel://pecl.php.net/mcrypt-1.0.1
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

抓取安装路径并添加到cli和apache2 php.ini配置。

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/cli/conf.d/mcrypt.ini"
sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

验证是否已安装扩展

运行命令：

php -i | grep "mcrypt"

输出将如下所示：

/etc/php/7.2/cli/conf.d/mcrypt.ini
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

Answer 3

我按照以下步骤使用PECL安装了用于PHP7.2的mcrypt。

1. 安装PECL

apt-get-install-php-pecl

apt get安装libmcrypt dev libreadline dev

pcl安装mcrypt-1.0.1

您应该在php.ini中添加“extension=mcrypt.so”

如果您需要任何帮助，请在下面发表评论。：-）

重要的

根据php.net参考资料，从PHP7.1.0开始，许多（所有）mcrypt函数已被弃用。非常不鼓励依赖此功能。
