Knot DNS has several dependencies:
* libtool
* autoconf > 2.65
* gnutls >= 3.0
* jansson >= 2.3
* lmdb (system library is preferred)
* libcap-ng >= 0.6.4 (for POSIX 1003.1e capabilities(7))
* libidn (for IDNA2003 support in Knot utilities)
* libsystemd (for systemd init system support)
Dependencies for building documentation:
* python-sphinx
Knot DNS may already be included in your operating system distribution and
therefore can be installed from packages (Linux), ports (BSD) or via
Homebrew (Mac). This is always preferred unless you want to test the latest
features, contribute to Knot development, or you just know what you are doing.
Following sections describe how to build Knot DNS from the source code.
Debian based distributions
--------------------------
Update the system:
libtool autoconf make pkg-config liburcu-dev libgnutls28-dev libjansson-dev libedit-dev
Install optional packages to override embedded libraries:
$ sudo apt-get install liblmdb-dev
Install optional packages:
$ sudo apt-get install libcap-ng-dev libsystemd-dev libidn11-dev protobuf-c-compiler libfstrm-dev
Fedora like distributions
-------------------------
Install basic development tools:
# dnf install \
libtool autoconf pkgconfig automake userspace-rcu-devel gnutls-devel jansson-devel libedit-devel
Install optional packages to override embedded libraries:
# dnf install libcap-ng-devel systemd-devel libidn-devel protobuf-c-devel fstrm-devel
When compiling on RHEL based system, the Fedora EPEL repository has to be
enabled. Also for RHEL 6, forward compatibility package gnutls30-devel
with newer GnuTLS is required instead of gnutls-devel.
2) Install Knot DNS
Knot DNS requires compiler to support atomic intrinsics.
GCC version at least 4.1 supports legacy atomic builtins, however 4.7
or newer is preferred. Clang supports atomics since version 2.9.
Get the source code:
$ git clone git://git.nic.cz/knot-dns.git
Or extract source package to knot-dns directory
Compile Knot
$ cd knot-dns
$ autoreconf -if
$ ./configure
$ make
Install Knot DNS into system:
$ sudo make install
$ sudo ldconfig
NOTE: If you want to reduce zscanner compile time, use configure option --disable-fastparser.
Running
=======
1) Each server needs configuration file. Please see samples/knot.sample.conf,
project documentation, or man 5 knot.conf for more details.
- storage for PID files, journal files etc.
- network interfaces
- served zones
E.g. use the default config file:
$ cd /etc/knot
$ mv knot.sample.conf knot.conf
Modify the config:
2) Prepare working directory
$ mv example.com.zone /var/lib/knot/
3) Start the server. This can be done by running the 'knotd' command.
Alternatively, your distribution should have an init script available, if you've
installed Knot using a binary package.
Start Knot in the foreground to see if it runs:
For more information, refer to the user manual or:
$ knotc -h
$ knotd -h
