security/easy-rsa is very close to this.

# easyrsa init-pki

# easyrsa build-ca

# easyrsa build-server-full <your_server>

# easyrsa build-client-full <client_name1>

# easyrsa build-client-full <client_name2>

# easyrsa build-client-full <client_nameN>

or

# easyrsa build-client-full <client_nameN> nopass

And usually

# easyrsa gen-dh

With "build-ca" you will create key and certificate for you private CA
With "build-server-full" you will create key and certificate for your server
With "build-client-full" you will create key and certificate for clients

It also supports "revoke" and "gen-crl" to revoke compromised 
certificate and update CRL.

Yes, it could be made a bit simpler and run init-pki in the background 
if build-ca is run for the first time so you can save one step.
I don't say easy-rsa is the best choice. I am able to use full openssl 
commands or write my own tools / scripts around it  I choose easy-rsa on 
machines where somebody else needs to work with certs.
