Dependencies ============ Knot DNS has several dependencies: * libtool * autoconf > 2.65 * pkg-config * liburcu >= 0.5.4 * gnutls >= 3.0 * jansson >= 2.3 * libedit Embedded libraries: * lmdb (system library is preferred) Optional packages: * 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 Installation ============ 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. 1) Install prerequisites Debian based distributions -------------------------- Update the system: $ sudo apt-get update $ sudo apt-get upgrade Install prerequisites: $ sudo apt-get install \ 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 ------------------------- Update the system: # dnf upgrade Install basic development tools: # dnf install @buildsys-build Install prerequisites: # dnf install \ libtool autoconf pkgconfig automake userspace-rcu-devel gnutls-devel jansson-devel libedit-devel Install optional packages to override embedded libraries: # dnf install lmdb-devel Install optional packages: # 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. Configuration file has to specify: - 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: $ editor knot.conf 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: $ knotd -c myserver.conf For more information, refer to the user manual or: $ knotc -h $ knotd -h Join the chat at https://gitter.im/CZ-NIC/knot
Knot DNS is a high-performance authoritative-only DNS server which supports all key features of the domain name system including zone transfers and DNSSEC.
