Which order in the setup process?

Hi! I´ve checked out different guides but Im not 100% sure in which order to do what?

• Disable SE LINUX (permanent or temporarily?)
• Vultr startup scripts
• Optional pre-installs

What does these do?
( I´ve read other tutorials but none of them does these steps)

• 1. Setup The Default Server Main Hostname Nginx Vhost
• 3. Setup Domain Name Newdomain.Com's DNS Settings

 

Hi again! So I got a swedish VPS and they dont have many of the admin panel functions that other VPS providers have so I think I will have to understand step 1 and 3 a little bit. ( Im using cloudflare)

1. Setup the default server main hostname Nginx vhost.
What do I do with this? ( Sorry for the noob question, but I dont understand what this does)

Code:

[root@localhost ~]# uname -n
localhost.localdomain

2. Add your first domain name's Nginx vhost configuration.
I can skip this step if im only going to create wordpress sites via option #22 right?

3. Setup domain name newdomain.com's DNS settings.
My VPS provider doenst have DNS management in their panel, but do I need to add it if Im going to use cloudflare? Isnt it enough to just point my nameregistrar to cloudflare and cloudflares A and AAAA records to my server IP?

5. Proxies and visitor's real IP address.
If I use the latest beta with cloudflare, I only need to add this line right?

Code:

23 */168 * * * /usr/local/src/centminmod/tools/csfcf.sh auto >/dev/null 2>&1
