Userland APCU cache and i-MSCP customer' sites

@raln

Helo ;

Depending on the i-MSCP httpd server implementation in use on your server, you must add the needed APC directives, either:

• in the pool configuration files located at /etc/php5/fpm/pool.d if you're using PHP5-FPM
• in the php.ini files located under /var/www/fcgi if you're using FCGID
• in the php.ini file located at /etc/php5/apache2/php.ini if you're using ITK

If you want those changes persistent for all your customers, you could instead edit the related templates which can be found under the /etc/imscp directory (just search a bit), and once done, you should rerun the imscp-setup script to regenerate all configuration files.

Hello;

Tell us what you have done exactly to enable APCU.

Give me some minutes. I'll give a try with ITK.

BTW: Where did you downloaded that APCU interface?

Ok, give me some minutes to test.

It works for me.

Howto (tested under Ubuntu Trusty)

• I've installed the php5-apcu package:
  
  
  Shell-Script

  1. # aptitude install php5-apcu
• I've run the following command to be sure that APCU is enabled:
  
  
  PHP

  1. # php5enmod apcu

  Note: It is useless to add the extension = apcu.so in the php.ini file since there is already an /etc/php5/mods-available/apcu.ini file.
  

• I've edited the /etc/php5/apache2/php.ini file and changed the folllowing configuration snippet:
  
  
  PHP

  1. [apc]apc.enabled = 0

  by

  PHP

  1. [apc]apc.enabled = 1
• I've restarted Apache2
  
  
  Shell-Script

  1. # service apache2 restart
• I've copied the apc.php file in my htdocs folder:
  
  
  Shell-Script

  1. root@trusty:/var/www/virtual/test.tld/htdocs# cp /usr/share/doc/php5-apcu/apc.php .root@trusty:/var/www/virtual/test.tld/htdocs# chown vu2003.vu2003 apc.php
• I've created an index.php file with the following content:
  
  
  PHP

  1. <?php// Add num variable to data storeapc_add('num', 1); // Print initial valueecho "Initial value: ", apc_fetch('num'), [b]"<br />"[/b]; // Update old value with a new valueapc_cas('num', 1, 10); // Print just updated valueecho "Updated value: ", apc_fetch('num'), "<br />"; // Decrease a stored numberecho "Decrease 1: ", apc_dec('num'), "<br />";echo "Decrease 3: ", apc_dec('num', 3), "<br />"; // Increase a stored numberecho "Increase 2: ", apc_inc('num', 2), "<br />";echo "Increase 1: ", apc_inc('num'), "<br />";
• I've loaded the index.php file. Result was:
  
  
  Code

  1. Initial value: 1
  2. Updated value: 10
  3. Decrease 1: 9
  4. Decrease 3: 6
  5. Increase 2: 8
  6. Increase 1: 9
• I've loaded the apc.php file. Result was:
