安装php7.2-mcrypt时出现的问题

39

我正在尝试从PHP 7.2.X版本加载mcrypt扩展模块。
因此，我尝试使用与当前PHP版本兼容的PECL库来安装，并遵循此链接：在安装期间安装mcrypt到PHP 7.2！

这些是在终端上执行某些命令后获得的结果。

YYY@YYY:/var/www/html/orocrm$ sudo pecl7.2-sp install --nodeps mcrypt-snapshot
sudo: pecl7.2-sp: command not found

由于出现了pecl7.2-sp: command not found的错误，根据文档部分所述，该命令已被弃用，并且从PHP 7.2.X版本开始不再提供支持，这是为了考虑安全性。

但是某些项目需要这些依赖项才能按照必要的方式执行所需的功能。我该如何解决上述问题？

更新：

简而言之：

我得到了很多来自答案投票的回应。答案需要根据操作系统架构级别进行分类。由于我正在使用共享服务器进行托管，因此有多个项目驻留在其中，并使用PHP 5.X.X版本编码，因此我决定降级到默认支持mcrypt扩展的PHP 7.1.X。

正如我在安装mcrypt扩展到PHP 7.2中所提到的，由Server Pilot社区提供。这些人告诉我们可以安装pecl-7.2的新版本以在PHP-7.2上安装mcrypt。不幸的是，尝试执行的命令以pecl7.2-sp: command not found结束，这与网站页面的更新不匹配，因此出现了这个问题。

最后，无论哪种解决方案适合您的操作系统架构级别，都可以尝试。

或者

如果以下方法未能解决根本原因。
或者，您可以选择支持mcrypt扩展的PHP 7.1.X版本

你应该考虑从现有应用程序中删除mcrypt使用，而不是在新服务器上安装它。 - Narf

尝试使用pecl而不是pecl7.2-sp。 - Praneeth Nidarshan

Mcrypt 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

当你看到提示时

 libmcrypt prefix? [autodetect] :

按 [回车] 键自动检测。

成功通过 pecl 安装 mcrypt 后，您应该将 mcrypt.so 扩展添加到 php.ini 中。

输出结果将会是这样：

...
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

获取安装路径并将其添加到cli和apache2 php.ini配置中。

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"

确认扩展程序已安装

运行命令：

php -i | grep "mcrypt"

输出结果将会像这样：

/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

在Windows中使用WAMP怎么样？PHP > 7.0。 - Pragnesh Karia

@pragnesh-karia 虽然在 Windows 上安装该库是可能的，但如果您使用 Linux Vagrant 虚拟机，将为您省去很多麻烦。 - Alberto

这个答案可以，但我还需要安装 php-dev 包。 - Tuxman

@PrafullaKumarSahu，你需要安装php-pear、php-dev和libmcrypt-dev软件包才能运行这些命令。 - Arda

@PragneshKaria，你找到任何解决方案了吗？ - Gem

安装 '/usr/lib/php/20170718/mcrypt.so'。我在我的机器上有多个PHP版本。我的当前PHP CLI版本是7.2，但当我安装mcrypt时，它被安装到了PHP 5.6。我该如何将其安装到7.2？ - Ejaz

@praneeth-nidarshan已经覆盖了大部分步骤，但还有一些：

检查是否安装了pear（或安装）：

$ sudo apt-get install php-pear

如未安装，安装php7.2-dev以避免错误：

sh：phpize：未找到

ERROR：`phpize'失败

$ sudo apt-get install php7.2-dev

使用pecl安装mcrypt：

$ sudo pecl install mcrypt-1.0.1

将扩展extension=mcrypt.so添加到php.ini配置文件中；如果您不知道它在哪里，请搜索：

$ sudo php -i | grep 'Configuration File'

- SimionZ

sudo apt-get install php-pear php7.x-dev

x是您的PHP版本，例如7.2，php7.2-dev

apt-get install libmcrypt-dev libreadline-dev
pecl install mcrypt-1.0.1

然后在"/etc/php/7.2/apache2/php.ini"中添加"extension=mcrypt.so"。

这里的php.ini取决于您的php安装和apache使用的php版本。

作为替代方案，您可以安装7.1版本的mcrypt并创建一个符号链接： 安装php7.1-mcrypt：

sudo apt install php7.1-mcrypt

创建符号链接：

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

在通过sudo phpenmod mcrypt启用mcrypt后，它就可以使用了。"Original Answer"翻译成"最初的回答"。

经过数小时的研究，我需要的那一部分是最后一段！在我的情况下，它是：sudo phpenmod -v 7.3 mcrypt。 - cdsaenz

sudo apt install php-dev libmcrypt-dev php-pear
sudo pecl channel-update pecl.php.net
sudo pecl install mcrypt-1.0.1

最后，运行以下命令打开PHP配置文件

sudo nano /etc/php/7.2/cli/php.ini 然后在文件中添加以下行，在[PHP]下方保存...

extension=mcrypt.so

对于Apache2

sudo nano /etc/php/7.2/apache2/php.ini

对于Nginx

sudo nano /etc/php/7.2/fpm/php.ini

你可以重新启动 PHP

sudo service php7.2-fpm restart

我按照以下步骤使用PECL安装了PHP7.2的mcrypt。

安装PECL

apt-get install php-pecl

在安装MCRYPT之前，必须先安装libmcrypt

apt-get install libmcrypt-dev libreadline-dev

使用PECL安装MCRYPT 1.0.1

pecl install mcrypt-1.0.1

安装成功后

您应该将 "extension=mcrypt.so" 添加到php.ini

如果需要任何帮助，请在下面发表评论。:-)

重要提示！

根据php.net参考，自PHP 7.1.0起，许多（所有）mcrypt函数已被弃用。不建议依赖此函数。
