Testing memcached with telnet
Start up a server on the localhost listening to some arbitrary port:
memcached -l 127.0.0.1 -p 12345 -m 64 -vv
-m 64 switch is really just there for explicitness, seeing as memcached defaults to using 64MB of memory by default anyway.
-vv turns on verbose logging so that we can see what's happening.
-p switch is omitted memcached will use the default port of 11211.
Now from another console login via telnet:
telnet localhost 12345
We can issue
get greeting END
So nothing was found. Now let's store something:
set greeting 1 0 11 Hello world STORED
That means, "use key
1 as flag (arbitrary metadata), use
0 as the expiry (ie. never expire), and expect the value to be 11 bytes long".
Now we can get the value back out:
get greeting VALUE greeting 1 11 Hello world END
And we're done:
