How do I see if memcached is already running on my chosen port?
I am having some problems with memcached and one idea I am having is that perhaps it is already running on the port I am trying to run it on, started by some other user on our network. Is there a way to tell what memcached ports are currently in use?
Answer
To see if it is running you could also try telnetting into the port:
telnet localhost 11211
If this works you will see the following (telling you that the given port is open):
Connected to localhost.
Escape character is '^]'.
Now if memcached IS running you can see some basic stats by issuing the given command:
stats
If this fails you will know that memcached is not running.
