4 The recommended way of installing Icinga 2 is to use packages. The Icinga
5 project provides both release and development packages for a number
8 Please check the documentation in the doc/ directory for a current list
9 of available packages and detailed installation instructions.
11 There are a number of known caveats when installing from source such as
12 incorrect directory and file permissions. So even if you're planning to
13 not use the official packages it is advisable to build your own Debian
19 The following requirements need to be fulfilled in order to build the
20 application using a dist tarball (package names for RHEL and Debian in
25 * C++ compiler (gcc-c++ on RHEL, build-essential on Debian)
26 * OpenSSL library and header files (openssl-devel on RHEL, libssl-dev
28 * Boost library and header files (boost-devel on RHEL, libboost-all-dev
31 * GNU flex (flex) >= 2.5.35
32 * recommended: libexecinfo on FreeBSD
33 * optional: MySQL (mysql-devel on RHEL, libmysqlclient-dev on Debian)
34 * optional: Python (python-devel on RHEL, python-dev on Debian)
36 Note: RHEL5 ships an ancient flex version. Updated packages are available for
37 example from the repoforge buildtools repository.

44 By default Icinga will run as user 'icinga' and group 'icinga'. Additionally the
45 external command pipe and livestatus features require a dedicated command group
46 'icingacmd'. You can choose your own user/group names and pass them to the
47 configure script using the --with-icinga-user, --with-icinga-group,
48 --with-icingacmd-user and --with-icingacmd-group options.
52 # useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga
54 Add the web server user to the icingacmd group in order to grant it write
55 permissions to the external command pipe and livestatus socket:
57 # usermod -a -G icingacmd www-data
59 Make sure to replace "www-data" with the name of the user your web server
62 Building Release Tarballs
63 -------------------------
65 In order to build a release tarball you should first check out the Git repository
66 in a new directory. If you're using an existing check-out you should make sure
67 that there are no local modifications:
71 Here's a short check-list for releases:
73 * Bump the version in icinga2.spec.
74 * Update the ChangeLog and doc/1-about.md files.
75 * Commit these changes to the "next" branch and create a signed tag (tags/v<VERSION>).
76 * Merge the "next" branch into the "master" branch (using --ff-only).
77 * Bump the version to "v<NEXT-VERSION>-dev" and commit this change to the "next" branch.
79 Note: CMake determines the Icinga 2 version number using "git describe" if the
80 source directory is contained in a Git repository. Otherwise the version number
81 is extracted from the icinga2.spec file. This behavior can be overridden by
82 creating a file called "icinga-version.h.force" in the source directory.
83 Alternatively the -DICINGA2_GIT_VERSION_INFO=ON option for CMake can be used to
84 disable the usage of "git describe".
86 Use "git archive" to build the release tarball:
88 $ git archive --format=tgz --prefix=icinga2-<VERSION>/ tags/v<VERSION>
90 Finally you should verify that the tarball only contains the files it should contain:
92 $ tar ztf icinga2-<VERSION>.tar.gz | less
97 Once you have installed all the necessary build requirements you can build
98 Icinga 2 using the following commands:
100 $ mkdir build && cd build
105 You can specify an alternative installation prefix using -DCMAKE_INSTALL_PREFIX:
107 $ cmake .. -DCMAKE_INSTALL_PREFIX=/tmp/icinga2
109 In addition to CMAKE_INSTALL_PREFIX the following Icinga-specific cmake
110 variables are supported:
112 - ICINGA2_USER: The user Icinga 2 should run as; defaults to "icinga"
113 - ICINGA2_GROUP: The group Icinga 2 should run as; defaults to "icinga"
114 - ICINGA2_COMMAND_USER: The command user Icinga 2 should use; defaults to "icinga"
115 - ICINGA2_COMMAND_GROUP: The command group Icinga 2 should use; default to "icingacmd"
116 - CMAKE_INSTALL_SYSCONFDIR: The configuration directory; defaults to CMAKE_INSTALL_PREFIX/etc
117 - CMAKE_INSTALL_LOCALSTATEDIR: The state directory; defaults to CMAKE_INSTALL_PREFIX/var
122 Icinga 2 comes with a single binary that takes care of loading all the relevant
123 components (e.g. for check execution, notifications, etc.):
126 [2013-10-22 13:06:22 +0200] <Main Thread> information/icinga-app: Icinga application loader (version: 0.0.3, git branch master, commit 07d9a59f + changes)

130 [2013-10-22 13:06:22 +0200] <Main Thread> critical/icinga-app: You need to specify at least one config file (using the --config option).
132 Icinga 2 can be started as daemon using the provided init script:
134 # /etc/init.d/icinga2
135 Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
137 Icinga 2 reads a single configuration file which is used to specify all
138 configuration settings (global settings, hosts, services, etc.). The
139 configuration format is explained in detail in the doc/ directory.
141 By default "make install" installs example configuration files in
142 /usr/local/etc/icinga2 unless you have specified a different prefix or
