+STEP 3: Compile and install Kea
-
-Kea requires a reasonably recent Boost version. Unfortunately, the
-version available in CentOS 7 is too old, so a newer Boost version is
-necessary. Furthermore, CentOS 7 has an old version of the g++ compiler
-that does not handle the latest Boost versions. Fortunately, Boost 1.65
-meets both requirements; it is both recent enough for Kea and can be
-compiled using the g++ 4.8 version in CentOS.
-
-To download and compile Boost 1.65, please use the following commands:
-
-.. code-block:: console
-
-   $ wget -nd https://boostorg.jfrog.io/artifactory/main/release/1.65.1/source/boost_1_65_1.tar.gz

-   $ cd boost_1_65_1/
-   $ ./bootstrap.sh
-   $ ./b2 --without-python
-   $ sudo ./b2 install
-
-Note that the ``b2`` script may optionally take extra parameters; one of
-them specifies the destination path where the sources are to be
-compiled.
-
-Alternatively, some systems provide newer Boost packages. For example,
-CentOS 7 provides ``boost169-devel``. If it is installed with
-``yum install boost169-devel``, Kea must be pointed to it with:
