2.13.10.1.2. Setting up Memcache in DLE

DLE can work with Memcache, but there is a flaw in its scripts that does not allow specifying the Memcache address as a unix socket.

To enable support Memcache in DLE:

1. Open the file engine/modules/functions.php and find the following code block in it:

   $mcache = false;
   if ($config['cache_type']) {
       if (function_exists('memcache_connect')) {
           $memcache_server = explode(":", $config['memcache_server']);
           $mcache = @memcache_connect($memcache_server[0], $memcache_server[1]);
           if ($mcache AND function_exists('memcache_set_compress_threshold')) {
               memcache_set_compress_threshold($mcache, 20000, 0.2);
           }
       }
   }

2. Replace the found block of code with this one:

   $mcache = false;
   if ($config['cache_type']) {
       if (function_exists('memcache_connect')) {
           $memcache_server = explode(":", $config['memcache_server']);
           if ($memcache_server[0] == 'unix') {
               $memcache_server = array($config['memcache_server'], 0);
           }
           $mcache = @memcache_connect($memcache_server[0], $memcache_server[1]);
           if ($mcache AND function_exists('memcache_set_compress_threshold')) {
               memcache_set_compress_threshold($mcache, 20000, 0.2);
           }
       }
   }

3. Open the site admin panel.
4. Go to the section "System Setup → Optimization».
5. In field "Data for connecting to the Memcache server»Specify unix:///home/example/.system/memcache/socketsubstituting instead example hosting account namein which the site is hosted.
6. Save your changes.
7. Check the site is working.
