[Koha] Changed IP, Can't connect to mysql server

[Robert Linebaugh]

I had to change the IP scheme of my network.  I have changed the interfaces, hosts and koha.conf files to reflect the new IP.  When I try to access Koha by typing http://koha.domain.com:8050 I get a 500 internal server error.  My opac-error_log file says:

Thu May 08 21:24:58 2008] [error] [client 72.227.31.7] DBI connect('Koha:10.0.250.4','kohaadmin',...) failed: Can't connect to MySQL server on '10.0.250.4' (111) at /usr/local/koha/intranet/modules/C4/Context.pm line 411

[Thu May 08 21:24:58 2008] [error] [client 72.227.31.7] Premature end of script headers: opac-main.pl

The Koha database is located on a different server that also received a new IP address.  Can anyone help me determine what configuration step I have missed.  I should also mention I am fairly new to Linux and Koha.

Thanks for the help
