Hi cookkoo,

did you probably forget to install "apt-get install plesk-php56-dev" ? If the package doesn't exist, please post the output of "apt-cache search plesk-php | grep dev".


As well, please post the output of the following command:

/opt/plesk/php/5.6/bin/pecl config-show

and

/opt/plesk/php/5.6/bin/php -v​

Hi cookkoo,

in addition, you could experience issues, because your local PECL configuration at "/root/.pearrc" could already be stored for your the vendor's configuration for your "PHP CLI/CGI binary" and your "php.ini location". In such cases, the command "/opt/plesk/php/N.N/bin/pecl config-show" ( where N.N is the placeholder for your Plesk PHP version 5.2/5.3/5.4/5.5 or 5.6 ) will show as output your ( vendors ) system PHP paths. To correct this issue, you have to perform the commands:

For Plesk PHP version 5.6 :​

/opt/plesk/php/5.6/bin/pecl config-set php_bin /opt/plesk/php/5.6/bin​

and​

/opt/plesk/php/5.6/bin/pecl config-set php_ini /opt/plesk/php/5.6/etc/php.ini
​

Afterwards, please retry your previous PECL installation and report again possible issues:

/opt/plesk/php/5.6/bin/pecl install memcached
​


Please note, that you should re-change your local PECL configuration to your previous state, after you finished the module installation for a Plesk PHP version, to avoid possible issues/problems with your server PHP version:

pecl config-set php_ini /etc/php5/cli/php.ini​
 
Hello UFHH01,

Thank you so much for your kindness and trying to help. Now on putty it display few error. as i am a civil & construction engineer not a programmer.

Hello UFHH01,

OK. I understand your answer. I will start the point from the top of this page, and the issue as below:

For this error you might use:

aptitude reinstall pkg-config

Could you explain, why you continue with the PECL installation, even that you see, that "pkg-config" os not installed yet? Sorry, but you really have to read the output from your command line, if you would like to solve the issue!


In case that you see a message like this "PACKAGENAME is not currently installed, so it will not be reinstalled", it states, that you have to INSTALL the version, because it isn't yet installed.

Please use

apt-get install pkg-config

... and again continue afterwards with your PECL installation:

/opt/plesk/php/5.6/bin/pecl install memcached​
 
Hello UFHH01,

Now my issue got FIX. And work very fine, I am not a programmer and so silly :)
But from a BIG help of you, my site can go ahead. I need to say THANK YOU AND THANK YOU AGAIN.
If i got some money from my site, i will take you to travelling around the world :)

Best Regards,
 
Why would any sane sysadmin want to run memcache in the default, single instance model, on a shared server? Unless things dramatically recently, memcache provides no authentication or other types of privilege separation which means users can easily read (or worse, write) other users keys.
 
Hello burnley, I thought Performance + Security should go together. from your information above, Please suggestion for How to protect that security issue ?
 
The only possible way to avoid the security issue is to run per-vhost memcached instances, which afaict isn't something Plesk configures out of the box.

As you can see, your repos are missing the actual "plesk-phpXX-devel" - packages, depending to your installed PHP - version. Pls. see as resolution: => #26
