installing cups 2.2.5 on centos 7

Hello everyone

I have a fresh centos 7 installation which I would like to setup as a print server. I downloaded latest cups version 2.2.5, extracted the file and then simply followed the
instructions on the INSTALL.md file. All did was

./configure
make
make install

There were no errors during the installation. I have 2 questions:

1. Why I can not see cups version 2.2.5 installed when I do

Code:

rpm -qa cups

? Is that because it wasn't an rpm pacakge?
2. Inside /etc/cups I can see the following files:

Code:

-rw-------. 1 root lp 0 Aug 3 19:41 classes.conf -rw-r--r--. 1 root lp 0 Aug 3 19:41 client.conf -rw-r--r--. 1 root root 1029 Oct 5 11:04 cups-browsed.conf -rw-r-----. 1 root lp 4552 Oct 18 16:24 cupsd.conf -rw-r-----. 1 root lp 6273 Oct 19 11:06 cupsd.conf.default -rw-r-----. 1 root lp 6273 Oct 19 11:06 cupsd.conf.N -rw-r-----. 1 root lp 3091 Oct 5 11:04 cups-files.conf -rw-r-----. 1 root lp 2944 Oct 19 11:06 cups-files.conf.default -rw-r-----. 1 root lp 2944 Oct 19 11:06 cups-files.conf.N drwxr-xr-x. 2 root root 6 Aug 3 19:40 interfaces -rw-r--r--. 1 root lp 0 Aug 3 19:41 lpoptions -rw-r--r--. 1 root root 319 Jun 22 2015 paps.convs drwxr-xr-x. 2 root lp 6 Aug 3 19:40 ppd -rw-------. 1 root lp 0 Aug 3 19:41 printers.conf -rw-r--r--. 1 root lp 186 Aug 3 19:40 snmp.conf -rw-r-----. 1 root lp 142 Oct 19 11:06 snmp.conf.default -rw-r-----. 1 root lp 142 Oct 19 11:06 snmp.conf.N drwx------. 2 root lp 6 Aug 3 19:40 ssl -rw-r-----. 1 root lp 408 Oct 18 15:34 subscriptions.conf -rw-r-----. 1 root lp 408 Oct 18 14:35 subscriptions.conf.O

The files with dated 19th October were created after the installation of cups 2.2.5. To start using cups2.2.5. I presume all I have to do is rename:

cupsd.conf.N --> cupsd.conf
cups-files.conf.N --> cups-files.conf
snmp.conf.N--> snmp.conf

Would that be the right procedure? Is there anything else I should consider?

Many thanks
