    Good morning,

    Is it possible to install memcached for the php 7.0.22 OS vendor?

    This article is fine, but it does not say how to install the module for your PHP 7.0.22 and I would need it.

    I have reviewed information and it is possible to compile it manually but I do not know if this will cause problems with your PLESK system.

    Can you confirm these points? Thank you very much.

    tried to follow the instruction for PHP 7.1 with Plesk 17.5.3 Update #38 on Ubuntu 14.04.5 but it stops with

    configure: error: no, libmemcached sasl support is not enabled. Run configure with --disable-memcached-sasl to disable this check.

    Tried with this flag but doesn't help. Any ideas?

    Hello!
    The libmemcached package for Ubuntu 14.04 does not support SASL authentication.
    Which error is displayed with the option -disable-memcached-sasl?

    the same error, it seems like the option is not detected. Tried it with -disable-memcached-sasl and --disable-memcached-sasl

    Hello!

    The issue requires mo detailed investigation, consider contacting Plesk Support.

    Also, consider contacting Ubuntu Support, as they are professionals in their product.

    Have installed it (on php 5.4 for centos) but can't start the server. Can't find the folder where it's installed. Where is it?

    The article is about installing php extension for memcached,  it is supposed that memcached server already installed. I think you just need to install memcached daemon.

     

    # yum install memcached

    or

    # apt-get install memcached

    You may also look at the blog post:

    After regular updates of php 5.6 I noticed that memcached stop working. I got error:

    PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/plesk/php/5.6/lib64/php/modules/memcache.so' - /opt/plesk/php/5.6/lib64/php/modules/memcache.so: cannot open shared object file: No such file or directory in Unknown on line 0

    It looks like update of package remove my memcached :)

    Has anyone experienced similarly problem?

    @Miha, there is a possibility that package update removed the whole PHP folder taking the memcached. Please vote for adding it to Plesk packages https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/6594919-memcached-support
