PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20100525

These options need to match

not sure how to resolve it

Try to re-compile it according to https://talk.plesk.com/threads/error-installing-mencached-plesk-12-5-centos-6-7.335075/#post-802651

I think that you need to remove module file and the corresponding entry in php.ini file first.

Hi Madness,

first of all, pls. get rid of your first error:

PHP Warning: PHP Startup: Unable to load dynamic library '/opt/plesk/php/5.6/li b64/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
PHP Warning: PHP Startup: memcache: Unable to initialize module

Command to use over the command line: /opt/plesk/php/5.6/bin/pecl uninstall memcache

... and don't forget to delete the depending *.ini - file, which automatically loads, when you placed it inside the folder "/opt/plesk/php/5.6/etc/php.d/"

Command to use over the command line: rm /opt/plesk/php/5.6/etc/php.d/memcache.ini

IMPORTANT:
If you placed the call of a module directly inside your "php.ini" , as for example with an entry like "extension=memcache.so" , pls. don't forget to delete such a manual entry from the "php.ini" !​

Second, to clean up your installation - mess, pls. consider to uninstall as well your previously ( unsuccessfully ) installed memcached - package:

Command to use over the command line: /opt/plesk/php/5.6/bin/pecl uninstall memcached

... and don't forget to delete the depending *.ini - file, which automatically loads, when you placed it inside the folder "/opt/plesk/php/5.6/etc/php.d/"

Command to use over the command line: rm /opt/plesk/php/5.6/etc/php.d/memcached.ini​

IMPORTANT:
If you placed the call of a module directly inside your "php.ini" , as for example with an entry like "extension=memcached.so" , pls. don't forget to delete such a manual entry from the "php.ini" !​

Third, pls. keep an eye on your typing, because memcache and memcached are different packages.



Fourth, pls. be informed, that you don't necessarily have to compile an existent pecl - package manually, if the latest release might not suit your environment or needs. You are always able to DOWNGRADE an installed pecl - package with for example:

/opt/plesk/php/5.6/bin/pecl install memcached-2.2.0RC1
( With this command, a previously installed "memcached" - package will be DOWNGRADED to the version "2.20RC1". The version can be choosen with the additional string marked in RED )​

If you are unsure, which PECL - extensions ( and different versions ) are available, pls. consider to visit: => https://pecl.php.net/package-search.php​

Additional notes:
PECL has as well additional install options, as for example the "-f" string, which forces an installation ( in case the requirements are not met, which are defined by the package maintainer ). Example: /opt/plesk/php/5.6/bin/pecl install -f memcached-2.2.0RC1

Another good idea is to use the install "-a" - string, which installs "all required and optional dependencies". Example: /opt/plesk/php/5.6/bin/pecl install -a memcached-2.2.0RC1
or
if you just desire to install only the "all required dependencies", you could use the install "-o" - string. Example: /opt/plesk/php/5.6/bin/pecl install -o memcached-2.2.0RC1


Pls. use the command "pecl help", or "pecl help COMMAND-NAME", to inform yourself about additional options, when you use PECL. Example: /opt/plesk/php/5.6/bin/pecl help install

Thank you for replying. I have followed the steps and tried to install again and im getting this:

libmemcached directory [no] : echo "extension=memcached.so" > /opt/plesk/php/5.6 /etc/php.d/memcached.ini

???

Pls. READ => https://devblog.plesk.com/2015/08/adding-custom-php-modules-in-plesk/

...
(when prompted for the libmemcached directory, leave it blank and hit the Enter key)
...

This means: WHEN you see on your command line: libmemcached directory [no] :
... then just leave it as it is and hit/press your keyboard key Enter/Return ( or what ever your key is labeled with ). The process will continue and the process will finish as expected without any issues/failures/problems.

AFTERWARDS ( when the whole process of compilitation and installation is finished!!! ), pls. use the command:

echo "extension=memcached.so" > /opt/plesk/php/5.6 /etc/php.d/memcached.ini

... which will create a file called "memcached.ini" in your directory "/opt/plesk/php/5.6 /etc/php.d", with the content: "extension=memcached.so"



Pls. just follow such instructions, as from the Plesk Developer Blog , step by step... they are really easy to understand and to follow, just like all suggestions and resolutions from KB - articles at the Plesk knowledge base !!!

Ive done everything you you said and i can see memcached in tools/php settings, but it still not showing in phpinfo.php

 

[UFHH01]

Hi Madness,

if you use PHP-FPM with the Plesk PHP - version X.X on your domain, where you tried to inspect the "phpinfo.php" at, did you as well RESTART the service, so that changes you made for the corresponding PHP - version are visible?

Ye I even restarted the server.

 

[UFHH01]

Hi Madness,

well, you now should see "memcached.ini" at the "Additional .ini files parsed" from your "phpinfo.php".

Additional settings are now done over your memcached server and it's configuration files ( for example: "/etc/sysconfig/memcached" ) , which you have to install with "yum install memcached" for CentOS 6.8 .

If you need further help "How to use memcached", pls. consider a Google search for example: => http://lmgtfy.com/?q="CentOS+6.8"+"memcached"

Hi Madness,

PHP Warning: PHP Startup: memcache: Unable to initialize module

... pls. note again the difference between "memcache" and "memcached" and pls. read again the suggestions, how to get rid of the "memcache" module : => #6

Hi Madness,



... pls. note again the difference between "memcache" and "memcached" and pls. read again the suggestions, how to get rid of the "memcache" module : => #6

Yes i did that its not installed.

soon as i add memchached to plesk and its visible in php settings this error starts

/etc/httpd/logs/error_log

PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20100525
PHP compiled with module API=20131226
These options need to match
in Unknown on line 0

Again ive not installed anything more than has been advised above and i have uninstalled as instructed #6

 

[UFHH01]

Hi Madness,

you could consider to use a serverwide search, as for example with:

find / -type f -name "*.*" -exec grep --color -Hni "memcache.so"  {} \;

... to find out, where the module "memcache.so" is loaded from and where the binary file is located on your server.
