votes

I have run a memcache server in aws. Installed memcache extension in modx server.

Then I update the settings in modx.

cache_handler -> cache.xPDOMemCache add a new key "resource_memcached_server" and value = xxx.com:11211

But I tail the log, there are some errors

Do you have a memcached server running? You need to provide the IP:PORT number for MODx.

As a very basic:

  • Ensure the memcache module for php is installed and working, php_info will check this
  • Set the cache_handler = cache.xPDOMemCache
  • Set memcached_server = myip:port

  • In you are going to use memcache for your system settings, you need to add these you your config.inc.php

    $config_options = array ( 'memcached_server' => 'server:port', 'system_settings_memcached_server' => 'server:port' );
