Setting up Private Nameservers in Cpanel
This guide will show you the ropes in how to setup cpanel nameservers and configure them properly so you can run ns1 and ns2.yoursite.com. Once your nameservers are setup clients can then use your own private nameservers for their domains.
1. Regiser your domain
Register the domain name you would like to use, you can register a domain here if you need one.This domain will be used as your nameservers - eg ns1.yourdomain.com and ns2.yourdomain.com
2. Additional IPs
Have 2 available IP addresses for your server that aren't in use.You will need to contact you provider to obtain these IP addreses.
3. Registering the Nameservers
Now login to your domain management page for the domain you registered and register ns1.newdomain.com and ns2.newdomain.com as nameservers (registries normally have a special facility for doing that). The registry may also have a facility to propogate these nameservers around the foreign registries - if so, you should use this facility.
These registrations may take a few days to propagate (often as many as 3 days).
4. Reverse DNS
You may also need to get your data centre to enter a reverse DNS pointer for your nameservers. You'll need to let them know each nameserver and its IP address. Sometimes you can suffer non-delivery of mail if you don't so this. Reverse DNS pointers can take a while to propagate.
Setup a reverse on the IP address for your domain
5. Broken NDC/BIND
My version of WHM/CPanel came with a broken NDC. To fix this:
SSH into your box as root.
(a) Type: cd /scripts
(b) Type: ./updatenow
(c) Type: ./fixndc
Go back into WHM, go to the Restart Services section in the left menu and click DNS/Nameserver (BIND).
You will need to do this if you start getting 'ndc' errors when you are doing anything DNS related in WHM.
6. Setup Nameservers In WHM
Go into WHM (Web Host Manager) and select Edit Setup from the Server Setup menu on the left. Enter ns1.newdomain.com in the Primary Nameserver field. Hit 'Assign IP Address', then hit 'Add an A Entry for this nameserver'.
Repeat this process for the Secondary Nameserver field.
7. Tidy Up Junk Nameservers
Go into WHM (Web Host Manager) and select Manage Nameserver IPs from the Server Setup menu on the left. Remove any nameservers you don't recognise. This is just a tidy up exercise in case anyone's set anything up on the box before you.
8. Initial Nameserver Setup
Go into WHM (Web Host Manager) and select Initial NameServer Setup from the Server Setup menu on the left. Run this.
9. Restart BIND
Restart BIND (step 7 restarts BIND, but we've known it to need a proper stop and start for it to work) from SSH with:
service named stop
service named start
10. Manual Checks
I don't know what it is about this process, but it doesn't always work, so there are some things you can check manually via SSH.
/etc/wwwacct.conf
Check that the nameservers are correctly specified on NS, NS2 etc.
EG: scroll to the name servers section.....
NS ns1.yournameserver.com
NS2 ns2.yournameserver.com
/etc/resolv.conf
Check that there are nameserver entries for each IP. There may also be one for 127.0.0.1 - this is okay. I'm led to believe (by the 'man' entry for resolv.conf) that this isn't a particularly important file, but I changed mine to read:
domain mybox.com
search mybox.com
nameserver 127.0.0.1
nameserver 111.111.111.111
nameserver 222.222.222.222
Where 'mybox.com' is the main domain of my server, and '111.111.111.111' and '222.222.222.222' are the IP addresses of my primary and secondary nameservers.
resolv.conf is used to lookup names that are not in FQDN format.
/etc/nameserverips
Check that there are entries for each IP acting as a nameserver.
EG:
IPHERE=ns1.yournameserver.com
IPHERE=ns2.yournameserver.com
Upgrade Guide From Red Hat 7.3 to 9.0
If you want to keep your server available for updates for another year then we suggest upgrading to Red Hat 9 through this tutorial.
Since no one has yet posted a how-to upgrade an old 7.3 redhat to the latest redhat 9.0, here is how you can do it. Commands you issue on shell are in GREEN as usual.
WARNING: WebhostGear and the author claim no responsibility for this HOWTO. If your computer doesn't function afterwards, blows up, or turns into a pile of ash, it wasn't my fault. I only list how to do the upgrade, it is up to you to decide if it is worth trying or not.
Lets Begin!
Log into your box using SSH and su to root.
# First get apt....
wget http://ftp.freshrpms.net/pub/freshrpms/redhat/7.3/apt/apt-0.5.5cnc5-fr0.rh73.2.i386.rpm
# Now install it.
rpm -i apt-0.5.5cnc5-fr0.rh73.2.i386.rpm
# If you have dependancy issues, fix them. I had one machine
# that did, another that didn't. It just depends on what rpm's
# you've installed before, and your control panel.
# You don't have to do this part, but I did it just to make sure
# everything is already up to date, this upgrades your system
# packages, pretty much same as up2date -uv:
apt-get update
apt-get dist-upgrade
# You can't go from 7.3 to 9.0, so first we upgrade to 8.0.
# To do that, you must:
pico /etc/apt/sources.list
# Within sources.list, you'll see that the 7.3 lines are
# uncommented. Comment them out with # symbols. Then go
# to the 8.0 section and uncomment them.
# Now you can update your server to 8.0:
apt-get update
apt-get dist-upgrade
# That will take about an hour on a dual xeon.
# Fetched 224MB in 7m42s (484kB/s)
# Once done, edit your sources file again:
pico /etc/apt/sources.list
# Like last time, comment out the 8.0, and uncomment 9.0.
# Now upgrade to 9.0:
apt-get update
apt-get dist-upgrade
# Fetched 238MB in 7m24s (537kB/s)
# Now you are at redhat 9.0. I did a up2date just for sake
# of mind. This will proceed to upgrade your kernel ... on my
# dual xeons, I ended up with kernel-smp-2.4.20-19.9.i686
up2date -uv
# Now some misc stuff I did to make sure everything was okay:
lilo -v -v
sync
# If you have problems with lilo and it being unable to find
# /boot/messages, just create the file and enter random
# text in there.
# You are done. Reboot.
shutdown -r now
