Manually running /scripts/rebuildhttpdconf required?

[tombarnsley]

Hi guys,

Recently we moved our server to a different external IP address as we changed datacentres.
The server is on CentOS6.

I didnt move the server so I couldnt really comment on what was done at the time.

The issue I have is that new sites dont appear to bind to the IP address even though they claim to be when you try to reapply the IP address. What I have to do is add a generic IP address to the server move the site to that IP address and then move it back. After this I rebuild httpd conf and it all works fine.

We never had to do this before and Google seems to draw a blank.

I thing the issue may be that the server is using 1:1 NAT and somewhere in the IP address change something has been missed.

Has anyone else had this issue?

Hello,

With NAT mode, try using "WHM >> IP Migration Wizard" to migrate to the new local IP address. Also, check to ensure the correct IP addresses are configured in the /var/cpanel/cpnat file.

Thank you.

Hi Michael,

The migration was many months ago and I believe that was what was done.

The cpnat file is correct and can be modified from WHM

[email protected] [/scripts]# cat /var/cpanel/cpnat
192.168.151.54 <external public IP>

Interestingly I have to add a dummy IP address change the IP address of the site to that address and change it back. That in fact is what solves the issue.

Here is the output of that procedure.

Changing ip for user.co.uk (user) to 192.168.0.1
Setting up for ip change..... Done
The remote dns zone is not consistent with the httpd.conf.
The current ip in httpd.conf is: 192.168.151.54.
The current ip in the dns zone is: <external IP address>!
<external IP address> will be switched to the new ip as well!
Changed all instances of <external IP address> -> [192.168.0.1] in user.co.uk
Updating httpd.conf....Done
System has 1 free ip.
