InnoDB Memcached Plugin in earlier version of MySQL 5.6

Question

Can we use InnoDB Memcached Plugin in an earlier version of MySQL 5.6, such as 5.1 or 5.5? I searched on the web but could not find anything about this.

I tried to do this, as follows. I downloaded MySQL-server-5.6.22-1.el7.x86_64.rpm and then run the following command to extract it:

rpm2cpio MySQL-server-5.6.22-1.el7.x86_64.rpm  | cpio -idmv

and then copied libmemcached.so from ~/usr/lib64/mysql/plugin to /usr/lib64/mysql/plugin ,and then from these instructions here ran the following command:

 mysql> install plugin daemon_memcached soname "libmemcached.so";

but I got the following error:

Can't open shared library 'libmemcached.so' (errno:8, API version for DAEMON plugin daemon_memcached not supported by this version of the server

My current version of MySQL is:

 mysql  Ver 15.1 Distrib 5.5.37-MariaDB, for Linux (x86_64) using readline 5.1

Any ideas to solve it?

我将发行版从MariaDB更改为MySQL，并在MySQL 5.1和5.5中测试了“ InnoDB Memcached插件”，但是此插件无法正常工作。
