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.

|

|
|
|
|
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] <Main Thread> information/icinga-app: Icinga application loader (version: 0.0.3, git branch master, commit 07d9a59f + changes)
|
|
[2013-10-22 13:06:22 +0200] <Main Thread> information/base: Adding library search dir: /usr/lib/icinga2
|
|
[2013-10-22 13:06:22 +0200] <Main Thread> information/base: Loading library 'libicinga.la'
|
|
[2013-10-22 13:06:22 +0200] <Main Thread> information/config: Adding include search dir: /usr/share/icinga2
|
|
[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).
|
|
|
|
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.
