When compiling on RHEL based system, the Fedora EPEL repository has to be enabled.

2. Install Knot DNS

Get the source code:

git clone https://gitlab.nic.cz/knot/knot-dns.git

Or extract source package to knot-dns directory.

Compile the source code:

cd knot-dns
autoreconf -if
./configure
make

Note that ./configure accepts various parameters (see ./configure --help). The following examples assume --sysconfdir=/etc and --localstatedir=/var/lib.

Install Knot DNS into system:

sudo make install
sudo ldconfig

Running

1. Ensure some configuration

doc/configuration.rst

Please see samples/knot.sample.conf, project documentation, or man 5 knot.conf for more details. Basically the configuration should specify:

• network interfaces
• served zones

E.g. use the default configuration file:

cd /etc/knot
mv knot.sample.conf knot.conf

Modify the configuration file:

editor knot.conf

2. Prepare working directory

mv example.com.zone /var/lib/knot/

3. Start the server

doc/operation.rst

This can be done by running the knotd command. Alternatively, your distribution should have an init script available, if you installed Knot DNS from a binary package.

Start the server in foreground to see if it runs:

knotd -c /etc/knot/knot.conf
