Migration of DA Server

[boonchuan]

I need to migrate my DA server from one datacenter to another. This involves IP changes. I can change the IPs of the server, no issue, but my main question what do I do in the Directadmin? Which parts do I access to change the IPs?

Any other things i need to take note?

Run the swapip script; it's in the DirectAdmin scripts directory.

Does anybody have a full how-to on migrating a server fully?

Take this code, throw it in a bash script:


#!/bin/bash
#
if [ $# -ne "2" ] # make sure all args are there
then
echo "Usage: $0 <ip/prefix> <hostname>";
exit 1;
fi

IPADDR="$1"
HOST="$2"

eval `/bin/ipcalc -s -b -p -n -m ${IPADDR}`

set `IFS=".";echo ${NETWORK}`
OCT4="$(($4 + 1))"
GWAY="$1.$2.$3.${OCT4}"

set `IFS=".";echo ${HOST}`
if [ "$1" == "${HOST}" ]
then
HOST="${HOST}.hostpc.com";
fi

echo "IP: ${IPADDR}"
echo "NM: ${NETMASK}"
echo "NW: ${NETWORK}"
echo "BC: ${BROADCAST}"
echo "GW: ${GWAY}"

IPADDR=$(echo $IPADDR | sed "s/\/.*//")

cd /usr/local/.bocacom

/etc/init.d/network stop
sleep 2

# Setup the IP address
echo "DEVICE=eth0" >/etc/sysconfig/network-scripts/ifcfg-eth0
echo "IPADDR=${IPADDR}" >>/etc/sysconfig/network-scripts/ifcfg-eth0
echo "NETMASK=${NETMASK}" >>/etc/sysconfig/network-scripts/ifcfg-eth0
echo "NETWORK=${NETWORK}" >>/etc/sysconfig/network-scripts/ifcfg-eth0
echo "BROADCAST=${BROADCAST}" >>/etc/sysconfig/network-scripts/ifcfg-eth0
echo "ONBOOT=YES" >>/etc/sysconfig/network-scripts/ifcfg-eth0

echo "nameserver 4.2.2.2" >/etc/resolv.conf
echo "nameserver 4.2.2.1" >>/etc/resolv.conf
echo "search YOURDOMAIN.com" >>/etc/resolv.conf

echo "NETWORKING=yes" >/etc/sysconfig/network
echo "HOSTNAME=${HOST}" >>/etc/sysconfig/network
echo "GATEWAY=${GWAY}" >>/etc/sysconfig/network

echo "127.0.0.1 localhost.localdomain localhost" >/etc/hosts
echo "${IPADDR} ${HOST}" >>/etc/hosts

hostname ${HOST}

echo "Shutting down system..."
shutdown now

Items in bold are the only thing you should have to change.

Run the script as root when it's ready to shutdown, before it's brought up on the new network

Joe can you please make it a bit more clear to which post you're responding?

Thanks.

The script I posted will migrate the server, ip's and net configurations to the new location.
