I have 2 application servers and a memcached server..
the following has been implemented in my config file..
$CFG->session_handler_class = '\core\session\memcached'; **
$CFG->session_memcached_save_path = '***.**.**.***';
$CFG->session_memcached_prefix = 'memc.sess.key.';
$CFG->session_memcached_acquire_lock_timeout = 120;
$CFG->session_memcached_lock_expire = 7200; // Ignored if memcached extension <= 2.1.0
How can we confirm if Memcached is installed ?
Did you mean to use memcached for sessions (as opposed to the MUC)?
memcached has built in statistics that you can interrogate from the command line - Google 'memcached statistics'
Yes for session handling which is hopefully going to improve the performance in a multi-server environment.
On 2 off the app servers i have an application of moodle set up.. in both config files i have :
$CFG->session_handler_class = '\core\session\memcached'; **
$CFG->session_memcached_save_path = '***.**.**.***';
$CFG->session_memcached_prefix = 'memc.sess.key.';
$CFG->session_memcached_acquire_lock_timeout = 120;
$CFG->session_memcached_lock_expire = 7200; // Ignored if memcached extension <= 2.1.0
I have the $CFG->session_memcached_save_path= 'set to the memcached server' when i run tcpdump port 11211 - i can see some activity
$CFG->session_handler_class = '\core\session\memcached'; ** not quite sure what this is for ?
please advise...
So - have you set up the MUC with its own memcached as well? That will make a substantially bigger difference than configuring the session handling.
No i dont think so.. how do i go about doing that ?
We are currently using Moodle 2.7 and have been advised, to improve the performance of our multi-server environment memcached (which is supported) should be used.
We have taken steps to have our two app servers updated with Memcached and also a 3rd (stand alone server) also with memcached installed.
However i am not quite sure how to configure this altogether !
Any steps to proceed would be greatly appreciated !
Thanx
Thanks for your help with this.
