Ok I installed Ubuntu server edition on my laptop. I installed all the componants for LAMP. So PHP, MySQL and Apache. And I also added SSH. So now what?
Open up your firewall to allow access and set your port forwarding.
Then get a domain name and get that side of it sorted. If you use BindDNS or a free DNS place like no-ip.
Add whatever you want to control it like webmin, cpanel or directadmin and then add content!!
I recommend webmin. That way you will have full control over your server.
I actually setup a new home server for myself just last night out of boredom lol. Although using Mandriva not Ubuntu but principal is identical.
One question. You have in your thread title. HELP!. What help do you require specifically?
It appears you have it largely sorted out??
@OP, what sort of specific questions do you have?
