I tried both port 11210 and 11212 with the above code, but I still get the same exception fail on openBucket:
Uncaught exception ‘Fuel\Core\PhpErrorException’ with message ‘file([CouchbaseNative]/CouchbaseBucket.class.php): failed to open stream: No such file or directory’ in /home/ec2-user/webapps/rest_api/fuel/core/classes/debug.php:324
By the way, I just notice I could connect to the defined memcached bucket ‘My-Bucket’ with port 8091 instead of either 11210 and 11212. Even though the memcached bucket port is configured as 11212.
Bucket Type: Memcached
Access Control: Dedicated port (supports ASCII portocol and is auth-less) Protocol port: 11212
But I guess I am not connecting to the memcached bucket in the right way you mentioned.
