Installing Icinga 2 =================== Please note that the current version of Icinga 2 isn't much more than a tech demo. Expect some rough edges when installing and running Icinga 2. For the "finished" version we're planning to release packages for the most common Linux distributions as well as for Windows - or at least co-operate with the package maintainers. Please check the documentation in the doc/ directory for a current list of available packages. Build Requirements ------------------ The following requirements need to be fulfilled in order to build the application using a dist tarball (package names for RHEL and Debian in parentheses): * cmake * GNU make (make) * C++ compiler (gcc-c++ on RHEL, build-essential on Debian) * OpenSSL library and header files (openssl-devel on RHEL, libssl-dev on Debian) * Boost library and header files (boost-devel on RHEL, libboost-all-dev on Debian) * GNU bison (bison) * GNU flex (flex) >= 2.5.35 * optional: Doxygen (doxygen) * optional: MySQL (mysql-devel on RHEL, libmysqlclient-dev on Debian) * optional: Python (python-devel on RHEL, python-dev on Debian) Note: RHEL5 ships an ancient flex version. Updated packages are available for example from the repoforge buildtools repository. http://mirror.hs-esslingen.de/repoforge/redhat/el5/en/{i386,x86_64}/buildtools/ User Requirements ----------------- By default Icinga will run as user 'icinga' and group 'icinga'. Additionally the external command pipe and livestatus features require a dedicated command group 'icingacmd'. You can choose your own user/group names and pass them to the configure script using the --with-icinga-user, --with-icinga-group, --with-icingacmd-user and --with-icingacmd-group options. # groupadd icinga # groupadd icingacmd # useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga Add the web server user to the icingacmd group in order to grant it write permissions to the external command pipe and livestatus socket: # usermod -a -G icingacmd www-data Make sure to replace "www-data" with the name of the user your web server is running as. Building Icinga 2 ----------------- Once you have installed all the necessary build requirements you can build Icinga 2 using the following commands: $ mkdir build && cd build $ cmake .. $ make $ make install You can specify an alternative installation prefix using -DCMAKE_INSTALL_PREFIX: $ cmake .. -DCMAKE_INSTALL_PREFIX=/tmp/icinga2 In addition to CMAKE_INSTALL_PREFIX the following Icinga-specific cmake variables are supported: - ICINGA2_USER: The user Icinga 2 should run as; defaults to "icinga" - ICINGA2_GROUP: The group Icinga 2 should run as; defaults to "icinga" - ICINGA2_COMMAND_USER: The command user Icinga 2 should use; defaults to "icinga" - ICINGA2_COMMAND_GROUP: The command group Icinga 2 should use; default to "icingacmd" - CMAKE_INSTALL_SYSCONFDIR: The configuration directory; defaults to CMAKE_INSTALL_PREFIX/etc - CMAKE_INSTALL_LOCALSTATEDIR: The state directory; defaults to CMAKE_INSTALL_PREFIX/var Running Icinga 2 ---------------- Icinga 2 comes with a single binary that takes care of loading all the relevant components (e.g. for check execution, notifications, etc.): # /usr/bin/icinga2 [2013-10-22 13:06:22 +0200]
information/icinga-app: Icinga application loader (version: 0.0.3, git branch master, commit 07d9a59f + changes) [2013-10-22 13:06:22 +0200]
information/base: Adding library search dir: /usr/lib/icinga2 [2013-10-22 13:06:22 +0200]
information/base: Loading library 'libicinga.la' [2013-10-22 13:06:22 +0200]
information/config: Adding include search dir: /usr/share/icinga2 [2013-10-22 13:06:22 +0200]
critical/icinga-app: You need to specify at least one config file (using the --config option). Icinga 2 can be started as daemon using the provided init script: # /etc/init.d/icinga2 Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status} Icinga 2 reads a single configuration file which is used to specify all configuration settings (global settings, hosts, services, etc.). The configuration format is explained in detail in the doc/ directory. By default "make install" installs example configuration files in /usr/local/etc/icinga2 unless you have specified a different prefix or sysconfdir.
