I found on the forum that you cannot use domain as hostname and its recommended to use svr1.domain.com
I am using this setup but i like to add svr1.domain.com to the admin users as domain so i can custom config to httpd (mod rewrite proxy etc.)
Voor tools that run on the server webside. I can ofc make them manually in the custom dir but having directadmin setup the basic templates is quite usefull.
Besides I like to know the reason.

So is this a no no (i gues) but why ?
What is the prefered way to access monitors custome interfaces run on the server in this example shellinabox.
 
I Guess the why is:
That changes for that domain / virtualhost then also could have influence on other services needed by the server/hostname.

For simple example to explain if you you for that domainname admin user in DA GUI a letsencyrypt cert then all other parts as in the hostname letsencrypt script are failing. ( then problems a lot )
 
I may not follow you totally. "srv1" is not a sub domain its a Hostname. Although you could be thinking of something else.
Your server should have a FDQN. Which is made up of host name and domain name.

All server need names like cats and dogs...

brent.cooldomain.com

Host name = brent
Domain name = cooldomain.com
FQQN = brent.cooldomain.com

Code: 
hostnamectl status
gives
Static hostname: brent.cooldomain.com

Code: 
hostnamectl -h
hostnamectl [OPTIONS...] COMMAND ...

Query or change system hostname.

  -h --help              Show this help
     --version           Show package version
     --no-ask-password   Do not prompt for password
  -H --host=[USER@]HOST  Operate on remote host
  -M --machine=CONTAINER Operate on local container
     --transient         Only set transient hostname
     --static            Only set static hostname
     --pretty            Only set pretty hostname

Commands:
  status                 Show current hostname settings
  set-hostname NAME      Set system hostname
  set-icon-name NAME     Set icon name for host
  set-chassis NAME       Set chassis type for host
  set-deployment NAME    Set deployment environment for host
  set-location NAME      Set location for host

Code: 
cat /etc/hosts
gives
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost localhost.localdomain
Your IP here brent.cooldomain.com brent
 
Ok so in my case it would be:

Host name = vps
Domain name = cooldomain.nl
FQQN = vps.cooldomain.nl

I have set hostname to vps.cooldomain.nl
So hostname is not that its actualy only vps.

[root@vps /]# hostnamectl status
Static hostname: vps.cooldomain.nl
Icon name: computer-vm
Chassis: vm
Machine ID: 353563dtshgrfth6545746453t5erge
Boot ID: 4235435tjjytjt35653ywrehhu57u5
Virtualization: kvm
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-1062.4.1.el7.x86_64
Architecture: x86-64

Zo mij host name is wrong then?

But still why would you not use vps.cooldomain.nl as a website in DA ?
 
Ok so currently your FDQN is vps.cooldomain.nl
This is your server. You should have this listed in you servers hosts file
Code: 
cat /etc/hosts

like:
Your IP here vps.cooldomain.nl vps

Your website is usually www.cooldomain.nl
Right?

If you want a subdomain use the subdomain management tool to create.
Something meaningful like "mycoolsubdomainname" as long as it's not "vps".

Click to expand...

"vps" is your servers name it's not a subdomain. Is this helping?

Kind of like your name is "spacecabbie". If we created another user here on the forum called "spacecabbie" . We would all be confused wondering who to speak too.
