will restarting apache clear my memcache contents?

Question

I just wanted to know if memcache is linked to apache or it runs as a separate process. So, will restarting apache clear my memcache contents or not?

Answer 1

No. Memcache is not linked to the apache process. Memcached is a separate process.

HOWEVER, your application framework if you are using one, may flush memcache if you restart apache.

You can also empty memcached without restarting it:

telnet localhost 11211

11211 it the default port for memcached (if nothing responds on this port check your init script)

And within telnet:

flush_all

This will flush all stored data.
