Two memcached servers for sessions - MichalSkoula - 03-13-2021
Hello,
Im using latest CI3.
I have started two memcached instances - 127.0.0.1:12345 and 127.0.0.1:12346
Now in my config.php I have:
PHP Code:
$config['sess_driver'] = 'memcached';
$config['sess_save_path'] = '127.0.0.1:12345,127.0.0.1:12346';
my php.ini:
Code:
memcached.sess_number_of_replicas = 2
memcached.sess_consistent_hash = on
memcached.sess_remove_failed_servers = on
memcached.sess_server_failure_limit = 3
memcached.store_retry_count = 2Now when both of the memcached instances are on, it works.
When I turn off the first and keep the second on, it works.
But when I turn off the second and keep the first on, it does not work - it tries for 12 seconds and then I have this error:
Message: session_start(): Failed to read session data: user (path: c:/wamp64/tmp)

PHP Code:
array (size=2)
0 =>
array (size=3)
'host' => string '127.0.0.1' (length=9)
'port' => int 12345
'type' => string 'TCP' (length=3)
1 =>
array (size=3)
'host' => string '127.0.0.1' (length=9)
'port' => int 12346
'type' => string 'TCP' (length=3)
this is dump from:
PHP Code:
var_dump($this->_memcached->getServerList ( ));

I see, memcached does not support replication. I should go with redis.
