I've installed centos a LOT of times, versions 5, 6, and 7, and never 
had any issues with the built in sshd service, and a variety of clients, 
including other linux ssh, putty and securecrt on windows, gui SCP/SFTP 
utilties(they use sshd too), freebsd ssh, solaris ssh, aix ssh.

the "key changed from known_hosts" error happens if your client had 
previously connected with  the same "user at hostname" on a previous 
installation of the server OS with a different ssh_host_key

you need to provide a lot more information if you expect a more specific 
answer from anyone, like what version of CentOS did you install, what 
client software you're using to connect to it, any pertinent background 
information like was this hostname previously used for a different OS 
install, etc etc.
