Resolved memcached PHP extension for PHP support instruction error

[pegasx]

Server operating system version

Centos 7.9

Plesk version and microupdate number

Plesk Obsidian v18.0.57

Hello,

I have tried to follow these instructions but ended with an error. ( https://support.plesk.com/hc/en-us/articles/12377651968023-How-to-install-uninstall-memcached-PHP-extension-for-Plesk-PHP-handlers )

These instruction will be failed if you want to change "igbinary => yes" on Centos 7.9. Could you please check it again?

igbinary is an optional component. If it is not installed on your server and you try to use it, the installation of the PHP memcached extension will fail. That is an expected behavior. If you want to use igbinary, you first need to install it.

I guess igbinary is installed and I see this error.

#rpm -qa|grep igbinary
php-pecl-igbinary-1.2.1-1.el7.x86_64

Please see one possible solution here: Installing php redis with igbinary, header file is not found

By copying needed .h files I have managed to install php memcached extension. But it did not run properly so I have decided to uninstall from console and plesk, it gives the same error.

# /opt/plesk/php/7.4/bin/pecl uninstall memcached
PHP Fatal error: Uncaught Error: Cannot use object of type PEAR_Error as array in /opt/plesk/php/7.4/share/pear/PEAR/Dependency2.php:1036

And unfortunately this is not resolved.

 

[Peter Debik]

Please check again. The error message that you quote is incomplete. The most important line is missing:



As the extension has not been installed properly or partly removed before, the automatic removal fails, because expected files are missing.

 

[pegasx]

I can not install or uninstall memcached extension.

# /opt/plesk/php/7.4/bin/pecl install memcached
pecl/memcached is already installed and is the same as the released version 3.2.0
install failed

You install igbinay in default php version and try use it in php 7.4

/opt/plesk/php/7.4/bin/pecl install igbinary

 

[pegasx]

I have run this:

/opt/plesk/php/7.4/bin/pecl install igbinary

But still I can not install or uninstall memcached extension.

What do you suggest?

I can remove php 7.4 and dependicies (webmail apps), and install back. Will it be a problem? Or any basic solution?

Regards.

There is no issue with the installation of igbinary. You only need to adapt the path to it as described in the previously provided link:

Please see one possible solution here: Installing php redis with igbinary, header file is not found

There is also no issue with deinstallation when you have a correct installation. But in your case it seems you have a messed up installation with missing files, so deinstall won't work either.

I have alreasdy copied to .h files to correct place, but that did not work even install or uninstall.

Reinstallion php7.4 did not work either.

I suggest to open a ticket with Plesk support so that they can check it on your server.
