Memcached has to start by nobody? How to start it?

Question

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?

Answer 1

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

Answer 2

-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
