3 The recommended way of installing Icinga 2 is to use packages. The Icinga
4 project provides both release and development packages for a number
7 Please check the documentation in the [doc/](doc/) directory for a current list
8 of available packages and detailed installation instructions.
10 There are a number of known caveats when installing from source such as
11 incorrect directory and file permissions. So even if you're planning to
12 not use the official packages it is advisable to build your own Debian
17 The following requirements need to be fulfilled in order to build the
18 application using a dist tarball (package names for RHEL and Debian in
23 * C++ compiler (gcc-c++ >= 4.7 on RHEL/SUSE, build-essential on Debian, alternatively clang++)
24 * OpenSSL library and header files >= 0.9.8 (openssl-devel on RHEL, libopenssl1-devel on SLES11,
25 libopenssl-devel on SLES12, libssl-dev on Debian)
26 * Boost library and header files (boost-devel on RHEL, libboost-all-dev on Debian)
28 * GNU flex (flex) >= 2.5.35
29 * recommended: libexecinfo on FreeBSD (automatically used when Icinga 2 is
30 installed via port or package)
31 * optional: MySQL (mysql-devel on RHEL, libmysqlclient-devel on SUSE, libmysqlclient-dev on Debian);
32 set CMake variable `ICINGA2_WITH_MYSQL` to `OFF` to disable this module
33 * optional: PostgreSQL (postgresql-devel on RHEL, libpq-dev on Debian); set CMake
34 variable `ICINGA2_WITH_PGSQL` to `OFF` to disable this module
35 * optional: YAJL (yajl-devel on RHEL, libyajl-dev on Debian)
36 * optional: libedit (libedit-devel on CentOS (RHEL requires rhel-7-server-optional-rpms
37 repository for el7 e.g.), libedit-dev on Debian)
38 * optional: Termcap (libtermcap-devel on RHEL, not necessary on Debian) - only
39 required if libedit doesn't already link against termcap/ncurses
41 Note: RHEL5 ships an ancient flex version. Updated packages are available for
42 example from the repoforge buildtools repository.
44 * x86: http://mirror.hs-esslingen.de/repoforge/redhat/el5/en/i386/buildtools/
45 * x86\_64: http://mirror.hs-esslingen.de/repoforge/redhat/el5/en/x86_64/buildtools/
49 By default Icinga will run as user 'icinga' and group 'icinga'. Additionally the
50 external command pipe and livestatus features require a dedicated command group
51 'icingacmd'. You can choose your own user/group names and pass them to CMake
52 using the `ICINGA2_USER`, `ICINGA2_GROUP` and `ICINGA2_COMMAND_GROUP` variables.
56 # useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga
58 Add the web server user to the icingacmd group in order to grant it write
59 permissions to the external command pipe and livestatus socket:
61 # usermod -a -G icingacmd www-data
63 Make sure to replace "www-data" with the name of the user your web server
68 Once you have installed all the necessary build requirements you can build
69 Icinga 2 using the following commands:
71 $ mkdir build && cd build
76 You can specify an alternative installation prefix using `-DCMAKE_INSTALL_PREFIX`:
78 $ cmake .. -DCMAKE_INSTALL_PREFIX=/tmp/icinga2
80 In addition to `CMAKE_INSTALL_PREFIX` the following Icinga-specific cmake
81 variables are supported:
83 - `ICINGA2_USER`: The user Icinga 2 should run as; defaults to `icinga`
84 - `ICINGA2_GROUP`: The group Icinga 2 should run as; defaults to `icinga`
85 - `ICINGA2_GIT_VERSION_INFO`: Whether to use Git to determine the version number; defaults to `ON`
86 - `ICINGA2_COMMAND_GROUP`: The command group Icinga 2 should use; defaults to `icingacmd`
87 - `ICINGA2_UNITY_BUILD`: Whether to perform a unity build; defaults to `ON`
88 - `ICINGA2_LTO_BUILD`: Whether to use link time optimization (LTO); defaults to `OFF`
89 - `ICINGA2_PLUGINDIR`: The path for the Monitoring Plugins project binaries; defaults to `/usr/lib/nagios/plugins`
90 - `ICINGA2_RUNDIR`: The location of the "run" directory; defaults to `CMAKE_INSTALL_LOCALSTATEDIR/run`
91 - `CMAKE_INSTALL_SYSCONFDIR`: The configuration directory; defaults to `CMAKE_INSTALL_PREFIX/etc`
92 - `ICINGA2_SYSCONFIGFILE`: Where to put the config file the initscript/systemd pulls it's dirs from;
93 defaults to `CMAKE_INSTALL_PREFIX/etc/sysconfig/icinga2`
94 - `CMAKE_INSTALL_LOCALSTATEDIR`: The state directory; defaults to `CMAKE_INSTALL_PREFIX/var`
95 - `USE_SYSTEMD=ON|OFF`: Use systemd or a classic SysV initscript; defaults to `OFF`
96 - `INSTALL_SYSTEMD_SERVICE_AND_INITSCRIPT=ON|OFF` Force install both the systemd service definition file
97 and the SysV initscript in parallel, regardless of how `USE_SYSTEMD` is set.
98 Only use this for special packaging purposes and if you know what you are doing.
100 - `ICINGA2_WITH_MYSQL`: Determines whether the MySQL IDO module is built; defaults to `ON`
101 - `ICINGA2_WITH_PGSQL`: Determines whether the PostgreSQL IDO module is built; defaults to `ON`
102 - `ICINGA2_WITH_CHECKER`: Determines whether the checker module is built; defaults to `ON`
103 - `ICINGA2_WITH_COMPAT`: Determines whether the compat module is built; defaults to `ON`
104 - `ICINGA2_WITH_DEMO`: Determines whether the demo module is built; defaults to `OFF`
105 - `ICINGA2_WITH_HELLO`: Determines whether the hello module is built; defaults to `OFF`
106 - `ICINGA2_WITH_LIVESTATUS`: Determines whether the Livestatus module is built; defaults to `ON`
107 - `ICINGA2_WITH_NOTIFICATION`: Determines whether the notification module is built; defaults to `ON`
108 - `ICINGA2_WITH_PERFDATA`: Determines whether the perfdata module is built; defaults to `ON`
110 CMake determines the Icinga 2 version number using `git describe` if the
111 source directory is contained in a Git repository. Otherwise the version number
112 is extracted from the [icinga2.spec](icinga2.spec) file. This behavior can be
113 overridden by creating a file called `icinga-version.h.force` in the source
114 directory. Alternatively the `-DICINGA2_GIT_VERSION_INFO=OFF` option for CMake
115 can be used to disable the usage of `git describe`.
117 ### Building Icinga 2 RPMs
119 Setup your build environment on RHEL/SUSE and copy the generated tarball from your git
120 repository to `rpmbuild/SOURCES`.
122 Copy the icinga2.spec file to `rpmbuild/SPEC` and then run this command:
124 $ rpmbuild -ba SPEC/icinga2.spec
126 ### Building Icinga 2 Debs
128 Setup your build environment on Debian/Ubuntu, copy the 'debian' directory from
129 the Debian packaging Git repository (https://anonscm.debian.org/cgit/pkg-nagios/pkg-icinga2.git)
130 into your source tree and run the following command:
132 $ dpkg-buildpackage -uc -us
134 ### Building Post Install Tasks
136 After building Icinga 2 yourself, your package build system should at least run the following post
137 install requirements:
139 * enable the `checker`, `notification` and `mainlog` feature by default
140 * run 'icinga2 api setup' in order to enable the `api` feature and generate SSL certificates for the node
145 Icinga 2 comes with a single binary that takes care of loading all the relevant
146 components (e.g. for check execution, notifications, etc.):
148 # /usr/sbin/icinga2 daemon
149 [2015-03-12 13:25:56 +0100] information/cli: Icinga application loader (version: v2.3.0-20-ga4d3713; debug)
150 [2015-03-12 13:25:56 +0100] information/cli: Loading application type: icinga/IcingaApplication
151 [2015-03-12 13:25:56 +0100] information/Utility: Loading library 'libicinga.dylib'
152 [2015-03-12 13:25:56 +0100] information/ConfigCompiler: Compiling config file: /Users/gunnar/i2/etc/icinga2/icinga2.conf
153 [2015-03-12 13:25:56 +0100] information/ConfigCompiler: Compiling config file: /Users/gunnar/i2/etc/icinga2/constants.conf
156 Icinga 2 can be started as a daemon using the provided init script:
158 # /etc/init.d/icinga2
159 Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
161 Or if your distribution uses systemd:
163 # systemctl {start|stop|reload|status|enable|disable} icinga2
165 Icinga 2 reads a single configuration file which is used to specify all
166 configuration settings (global settings, hosts, services, etc.). The
167 configuration format is explained in detail in the [doc/](doc/) directory.
169 By default `make install` installs example configuration files in
170 `/usr/local/etc/icinga2` unless you have specified a different prefix or
