How to start the daemon by nobody? Do I have to start as nobody?
I have only one box. So how many ports can I give to the daemon?
-u <username> assume identity of <username> (only when run as root)
So you can run
memcached -u nobody -d
the -d flag will launch it as a daemon in the background
memcached -h
That will list all the flags you can use
I just checked, by default on Debian it's launched as nobody. Just run:
/etc/init.d/memcached start
If you'r running CentOS or RedHat:
service memcached start
