"Network error: Connection refused" on Fedora

I have just installed Fedora. When I tried to putty(ssh) in, a PuTTY fatal Error was displayed, "Network error: Connection refused".

When I check the ssh status, it said not found.

[root@F20-64 ~]# service sshd status

Redirecting to /bin/systemctl status  sshd.service

sshd.service

   Loaded: not-found (Reason: No such file or directory)

   Active: inactive (dead)

The openssh server was not installed on fresh Fedora.
So I install the server.

[root@F20-64 ~]# yum install openssh-server

Checking the status again:

[root@F20-64 ~]# service sshd status

Redirecting to /bin/systemctl status  sshd.service

sshd.service - OpenSSH server daemon

   Loaded: loaded (/usr/lib/systemd/system/sshd.service; disabled)

   Active: inactive (dead)

Enable ssh server upon restart.

[root@F20-64 ~]# chkconfig sshd on

Note: Forwarding request to 'systemctl enable sshd.service'.

ln -s '/usr/lib/systemd/system/sshd.service' '/etc/systemd/system/multi-user.target.wants/sshd.service'

Start the ssh server service.

[root@F20-64 ~]# service sshd start

Redirecting to /bin/systemctl start  sshd.service
