Resolved Memcache and memcached on Plesk Onyx

New Pleskian
Hello, I am a fairly beginner and need help with step by step instruction on how can I install Memcache and Memcached on my server and PHP 7.1.1.

Have desperately searched the forum and googled around, but can not find the right answer

Thanks to all who respond and help

OS:‪Debian 7.11‬
Product Plesk Onyx Version 17.0.17 Update #16, last updated on Feb 15, 2017
 
Hi Igor, yes I have problem. So I need more help about this problem, and step by step instruction

Start module compilation now with

# /opt/plesk/php/7.1/bin/pecl install memcached

Then install module with

# echo "extension=memcached.so" > /opt/plesk/php/7.1/etc/php.d/memcached.ini

and reread php handlers with

# plesk bin php_handlers --reread

That's all.

I have just memcache activated on my PHP:

But not memcached

Looks like you have already installed memcached.so module but it is not loaded due to problems with libmemcached.so.11 loading. So, you do not need to compile it again. It is necessary to deal with the problem of loading libmemcached.so.11.

For example, on my Debian Jessie I see following:

# ls -la /usr/lib/x86_64-linux-gnu/libmemcached.so.11
lrwxrwxrwx 1 root root 22 Nov 13 2014 /usr/lib/x86_64-linux-gnu/libmemcached.so.11 -> libmemcached.so.11.0.0

The file belongs to libmemcached11 package:

# dpkg -S /usr/lib/x86_64-linux-gnu/libmemcached.so.11
libmemcached11:amd64: /usr/lib/x86_64-linux-gnu/libmemcached.so.11

Make sure that this package is installed.
 
Unfortunately, I can not figure out this.


#ls -la /usr/lib/x86_64-linux-gnu/libmemcached.so.10
lrwxrwxrwx 1 root root 22 Jun 5 2012 /usr/lib/x86_64-linux-gnu/libmemcached.so.10 -> libmemcached.so.10.0.0

#dpkg -S /usr/lib/x86_64-linux-gnu/libmemcached.so.10
libmemcached10:amd64: /usr/lib/x86_64-linux-gnu/libmemcached.so.10


# ls -la /usr/lib/x86_64-linux-gnu/libmemcached.so.11
ls: cannot access /usr/lib/x86_64-linux-gnu/libmemcached.so.11: No such file or directory

# dpkg -S /usr/lib/x86_64-linux-gnu/libmemcached.so.11
dpkg-query: no path found matching pattern /usr/lib/x86_64-linux-gnu/libmemcached.so.11


This driving me crazy ...

Thank you Igor
