我们正在努力让新的 Ubuntu Plesk 服务器运行 memcached，但在为 PHP 设置它时不断遇到错误。
使用来自 Plesk 的说明我们成功运行了以下操作：
apt install memcached autoconf automake gcc libmemcached-dev libhashkit-dev pkg-config plesk-php*-dev zlib1g-dev make
但是，当我们尝试安装 PHP 扩展时（在我们的例子中是 PHP 8.1），我们遇到了一个问题
/opt/plesk/php/8.1/bin/pecl install memcached
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
pecl/memcached can optionally use PHP extension "igbinary" (version >= 2.0)
pecl/memcached can optionally use PHP extension "msgpack" (version >= 2.0)

我注意到它在开始时引用了 pecl 通道的一个错误，因此我运行了：
pecl channel-update pecl.php.net
但之后的结果还是一样。

您可以尝试先运行“apt-get install libmemcached-tools”
