Install DHCP

Retrieve DHCP from http://isc.org/products/DHCP/ The latest release as of2012-06-26is DHCP-4.2.4.

Looks like they still can't write a good makefile dhcpd doesn't seem to listen to the -lf option.It wants to write its leases file in /var/db, so I have to set localstatedir in the config.Also, the -4 option doesn't work so I turn off ipv6 in configure.

Set a variable for the version to use

VERSION="4.2.4"

Compile

mkdir /tmp/root
cd /tmp/root
tar xfvz dhcp-${VERSION}.tar.gz
cd dhcp-${VERSION}
./configure --prefix=/opt/services/dhcp-${VERSION} --localstatedir=/opt/services/dhcp-${VERSION}/var --disable-dhcpv6
make
make install

Post installation

cd /opt/services
ln -s dhcp-${VERSION} dhcp
mkdir dhcp-${VERSION}/init.d
mkdir -p dhcp-${VERSION}/var/db
touch dhcp-${VERSION}/var/db/dhcpd.leases

Create start/stop script

Save the attached dhcp startup script as /opt/services/dhcp-${VERSION}/init.d/nrao-dhcpd

chmod 755 /opt/services/dhcp/init.d/nrao-dhcpd
ln -s /opt/services/dhcp/init.d/nrao-dhcpd /etc/init.d
chkconfig --add nrao-dhcpd
