hello. I've already installed my cwp but I'm trying to learn as much as I can to use it good, so I'm reinstalling it and trying to give a better configuration. I've been reading a lot of articles about every single command of the installation and the configuration, but while I was following the main cwp guide I had a couple of doubts.
1) the first step of the guide says I gotta set an hostname. Which one is best to use? I mean, I would probably just leave it "centos" or "cwp". Would that be good? What is the best practice?
2) the second step says to setup the server ip addresses. Here I'm a bit lost. When I get my vps, my ip is already setup... what should I setup exactly? can someone tell me more about this? The guide literally says 'Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information.' But when I get my vps, aren't those values already set?
3) is a swappiness value of 20 too little?
thanks

1. Use FQDN ex. edinburgh.mydomain.com
2. Ignore if you only have one IP address for your VPS, which you likely do. If you've used your povider's CentOS 7 template to install the server then the IP/mask/gateway will already be setup. It will probably be dynamic however and you should change to a static IP - Google it.
3. Set to either 1 or 5

if you've ssd and ram 3 gbs and up then disable the swap for better performance

After a 10 seconds extended search, one example:

Don't agree with this and goes against *nix memory handling. There are however, numerous arguments for/against swappiness. (I have a 128Mb swap on this SSD laptop, with vmswappiness=1 and there is some debate on whether 0 actually completely disables it.)

I'm following the guide... but I have doubt about it... when it says to edit the file ifcfg-interfacename and add network data such as ip, gateway and so on... ipaddr, gateway, network mask, dns... how can I know what to add? I'm sure its a noob question. I know my external ip, but how can I know the rest?

Blimey!
Suggest leaving it as is. :o

under ssd swap is not recommended.

normally I know how to handle those parameters in a network, but in a vps I never changed those things.
I guess it's needed when you have multiple vps or they must be part of a vpn, isn't it? are there other reason to change them?
Where can I read more about this?
So should I just change to static the ip without adding those @ejsolutions thanks a lot for your patience and help :)

cwp's first requirement is static ip

and you should ask local system admin if you're lost.
