2017-11-22: Kea 1.3.0 Source installation (with hooks) on Debian 9.2 with PostgreSQL support.

Introduction and System Description

Overview of installing and compiling Kea 1.3.0 from source tarball and git on Debian 9.2, with added PostgreSQL support.

$ prompt implies non-privileged user commands

# prompt implies privileged user commands (ie: run with sudo, or run as root)

Debian 9.2 Installation Notes

The Debian installation in this example was performed as a network install using the minimal install image.

See this how-to on a [https://www.howtoforge.com/tutorial/debian-minimal-server/ Debian minimal install]. The how-to linked is for Debian 9.1, but it should be the same for 9.2.

When the install gets to the {{{Software selection}}} screen, I chose only SSH server, and omitted all other options.

Setup of Packaged Prerequisites

The following list of packages is believed to be the complete list required for this use case.

# apt-get install automake libtool pkg-config libboost-dev libboost-system-dev liblog4cplus-dev build-essential libssl-dev ccache

Note on Postgres

If you want to compile Kea with PostgreSQL, support also install the following packages:

# apt-get install postgresql-server-dev-all libpq-dev 

Make sure you use --with-dhcp-pgsql (Kea 1.3) or --with-pgsql (Kea 1.4 or later) when running configure.

Note on development environment

If you want to compile Kea with unit-tests (not needed for users, only useful if you want to change Kea code and possibly contribute patches), you will need the following:

# apt-get install googletest libgtest-dev

Make sure you extend your configure script with --with-gtest-source=/usr/src/googletest as this is where Debian puts the Google test sources.

Note on git

If you are compiling from git source, clone the git repository and reconfigure

# apt-get install git
$ git clone https://github.com/isc-projects/kea.git

$ cd kea
$ autoreconf --install

Note on hooks library

If using hooks, copy the tarball into the root of the Kea source tree, and extract in place.

$ cp kea-subscription-1.3.0.tar.gz kea-1.3.0/
$ tar -zxvf kea-subscription-1.3.0.tar.gz

Building and Installing

The following environment variables attempt to speed up compilation, and recompilation.

$ export CC="ccache gcc" CXX="ccache g++"

Configure the installation. This example enables PostgreSQL and the Kea hooks library. Note that a Kea support is required to obtain the Kea hooks source tarball. If you don't know what this means, chances are the option will do nothing.

$ ./configure --with-dhcp-pgsql --with-tier2=yes

Starting with 1.4, the command line option for PostgreSQL will be --with-pgsql.

Compile and install the configured source tree. Assuming your Kea server has 2 CPU cores, substitute -jX with -j2

$ make -jX
# make install

Add the Kea libraries to ldconfig

# touch /etc/ld.so.conf.d/kea.conf
# echo "/usr/local/lib/hooks" > /etc/ld.so.conf.d/kea.conf
# ldconfig

Notes on Running

There is no startup script provided. Once Kea is correctly installed and configured for your environment, you will likely want to start it on boot. You can do so by simply adding the following to /etc/rc.local and enabling rc.local compatibility on your system.

# /etc/rc.local
#!/bin/bash
keactrl start
exit 0

See [https://lists.debian.org/debian-user/2014/08/msg01349.html This Link] for details in enabling rc.local compatibility.

Note: Debian's default systemd handles startup in more modern ways. rc.local compatibility is considered the old way.
