no response after running the command # echo "extension=memcache.so" > /opt/plesk/php/5.6/etc/php.d/memcache.ini

It is correct.

can not find it also in my php info

Have you started
# plesk bin php_handler --reread
And checked that module is loaded in Tools&Settings->PHP Settings->PHP5.6 ?

-bash: yum: command not found

yum is package manager of CentOS. For Debian use apt-get package manager. Names of required packages also may be different for Debian.

As I wrote before, names of required packages can be another on Debian. But you tried to use names of CentOS packages on your Debian server.
You need to run

# apt-get install make plesk-php71-dev gcc libmemcached-dev git pkg-config zlib1g-dev

 

[Arsenii Mironov]

Here is the list of commands for Plesk Onyx and Ubuntu 16.04:
apt install plesk-php71-dev gcc make git pkg-config zlib1g-dev libmemcached11 libmemcached-dev
git clone https://github.com/php-memcached-dev/php-memcached.git
cd php-memcached/
git checkout php7
/opt/plesk/php/7.1/bin/phpize
./configure --disable-memcached-sasl --with-php-config=/opt/plesk/php/7.1/bin/php-config
make && make install
echo "extension=memcached.so" > /opt/plesk/php/7.1/etc/php.d/memcached.ini
plesk bin php_handler --reread

Hi,
Can we get commands to install memcached on Plesk 12.5 under Debian 8 please ?

Cheers !

Hi Pascal_Netenvie,

Can we get commands to install memcached on Plesk 12.5 under Debian 8 please ?

Ubuntu and Debian have mostly the very same package - names, so pls. at least TRY the suggested commands that @Arsenii Mironov suggested with:

Here is the list of commands for Plesk Onyx and Ubuntu 16.04:
apt install plesk-php71-dev gcc make git pkg-config zlib1g-dev libmemcached11 libmemcached-dev
git clone https://github.com/php-memcached-dev/php-memcached.git
cd php-memcached/
git checkout php7
/opt/plesk/php/7.1/bin/phpize
./configure --disable-memcached-sasl --with-php-config=/opt/plesk/php/7.1/bin/php-config
make && make install
echo "extension=memcached.so" > /opt/plesk/php/7.1/etc/php.d/memcached.ini
plesk bin php_handler --reread

... especially, because the Plesk - paths doesn't differ at all on the operating systems, that Plesk supports.


If you experience any issues/errors/problems/, pls. don't hesitate to open a new thread, as this one is solved and answered.

 

[Pascal_Netenvie]

Thanks for your answer.
I ask before trying (despite i know Ubuntu is very close to Debian) because i work on a production server and we only have PHP 7.0.x.
So i prefer ask first instead of doing bullshits

Regards.

Here is the list of commands for Plesk Onyx and Ubuntu 16.04:
apt install plesk-php71-dev gcc make git pkg-config zlib1g-dev libmemcached11 libmemcached-dev
git clone php-memcached-dev/php-memcached

echo "extension=memcached.so" > /opt/plesk/php/7.1/etc/php.d/memcached.ini
plesk bin php_handler --reread

and for uninstalling ?

 

[IgorG]

and for uninstalling ?

# rm -f /opt/plesk/php/7.1/etc/php.d/memcached.ini
# plesk bin php_handler --reread

 

[Alaa Mansour]

# rm -f /opt/plesk/php/7.1/etc/php.d/memcached.ini
# plesk bin php_handler --reread

after I did a migration from a server where it was installed memcached.so to a new server without installing the memcached, because I don't want it anymore
I keep getting this email every 30 min:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/memcached.so' - /usr/lib/php/20151012/memcached.so: cannot open shared object file: No such file or directory in Unknown on line 0

I tried the uninstall command on both servers then migrate again, but the problem still persist
Issue - nginx: [emerg] a duplicate default server

Find php config file where memcached.so is loaded with

# grep -R "memcached.so" /etc/php.d/*
# grep -R "memcached.so" /opt/plesk/php/*/etc/*

and remove this file. After that run

# plesk bin php_handler --reread

# grep -R "memcached.so" /etc/php.d/*
# grep -R "memcached.so" /opt/plesk/php/*/etc/*

and remove this file. After that run

# plesk bin php_handler --reread

the first command result:

grep: /etc/php.d/*: No such file or directory

the second command gives me nothing

on the old server I found the 4 files
iam deleting them then I will let you know if I keep getting the email
thanks

Location of system php configs depends on your OS. My sample was for CentOS7. Try to find correct location for your OS.
