Installation

Centreon provides RPM packages for its products through the Centreon open source version available free of charge in our repository.

These packages have been successfully tested in version 7.x CentOS and Red Hat environments.

Alternatively, you can build and install your own version of this software by following the Using sources.

Before installing the software, please make sure that your platform is up to date, especially when using virtualization tools (VMware drivers notably).

Using packages

To install Centreon software from the repository, you should first install the centreon-release package, which will provide the repository file.

Install the Centreon repository using this command:

# yum install -y http://yum.centreon.com/standard/19.04/el7/stable/noarch/RPMS/centreon-release-19.04-1.el7.centos.noarch.rpm

The repository is now installed.

Install

Run the following commands as privileged user

$ yum install centreon-engine

All dependencies are automatically installed from Centreon repositories.

Using sources

To build Centreon Engine, you will need the following external dependencies:

  • a C++ compilation environment.
  • CMake (>= 2.8), a cross-platform build system.
  • Centreon Clib (>= 1.4), The centreon core library.

This program is compatible only with Unix-like platforms (Linux, FreeBSD, Solaris, ...).

Prerequisites

If you decide to build Centreon Engine from sources, we heavily recommand that you create dedicated system user and group for security purposes.

On all systems the commands to create a user and a group both named centreon-engine are as follow (need to run these as root)

$ groupadd centreon-engine
$ useradd -g centreon-engine -m -r -d /var/lib/centreon-engine centreon-engine

Please note that these user and group will be used in the next steps. If you decide to change user and/or group name here, please do so in further steps too.

Build

Get sources

Centreon Engine can be checked out from GitHub at https://github.com/centreon/centreon-engine. On a Linux box with git installed this is just a matter of

$ git clone https://github.com/centreon/centreon-engine

Or You can get the latest Centreon Engine’s sources from its download website Once downloaded, extract it

$ tar xzf centreon-engine.tar.gz

Configuration

At the root of the project directory you’ll find a build directory which holds build scripts. Generate the Makefile by running the following command

$ cd /path_to_centreon_engine/build

Your Centreon Engine can be tweaked to your particular needs using CMake’s variable system. Variables can be set like this

$ cmake -D<variable1>=<value1> [-D<variable2>=<value2>] .

Here’s the list of variables available and their description:

Variable Description Default value
WITH_BENCH Build benchmarking tools. OFF
WITH_CENTREON_CLIB_INCLUDE_DIR Set the directory path of centreon-clib include. auto detection
WITH_CENTREON_CLIB_LIBRARIES Set the centreon-clib library to use. auto detection
WITH_CENTREON_CLIB_LIBRARY_DIR Set the centreon-clib library directory (don’t use it if you use WITH_CENTREON_CLIB_LIBRARIES). auto detection
WITH_GROUP Set the group for Centreon Engine installation. root
WITH_LOCK_FILE Used by the startup script. /var/lock/subsys/centengine.lock
WITH_LOG_ARCHIVE_DIR Use to archive log files that have been rotated. ${WITH_VAR_DIR}/archives
WITH_LOGROTATE_DIR Use to install logrotate files. /etc/logrorate.d/
WITH_LOGROTATE_SCRIPT Enable or disable install logrotate files. OFF
WITH_PID_FILE This file contains the process id (PID) number of the running Centreon Engine process. /var/run/centengine.pid
WITH_PKGCONFIG_DIR Use to install pkg-config files. ${WITH_PREFIX_LIB}/pkgconfig
WITH_PKGCONFIG_SCRIPT Enable or disable install pkg-config files. ON
WITH_PREFIX Base directory for Centreon Engine installation. If other prefixes are expressed as relative paths, they are relative to this path. /usr/local
WITH_PREFIX_BIN Define specific directory for Centreon Engine binary. ${WITH_PREFIX}/bin
WITH_PREFIX_CONF Define specific directory for Centreon Engine configuration. ${WITH_PREFIX}/etc
WITH_PREFIX_INC Define specific directory for Centreon Engine headers. ${WITH_PREFIX}/include/centreon-engine
WITH_PREFIX_LIB Define specific directory for Centreon Engine modules. ${WITH_PREFIX}/lib/centreon-engine
WITH_RW_DIR Use for files to need read/write access. ${WITH_VAR_DIR}/rw
WITH_SAMPLE_CONFIG Install sample configuration files. ON
WITH_SHARED_LIB Build shared library for the core library. OFF
WITH_STARTUP_DIR Define the startup directory. Generaly in /etc/init.d or /etc/init
WITH_STARTUP_SCRIPT Generate and install startup script. Choices are ‘auto’, ‘sysv’ and ‘upstart’. auto
WITH_TESTING Build unit test. OFF
WITH_USER Set the user for Centreon Engine installation. root
WITH_VAR_DIR Define specific directory for temporary Centreon Engine files. ${WITH_PREFIX}/var

Example

$ cmake \
   -DWITH_PREFIX=/usr \
   -DWITH_PREFIX_BIN=/usr/sbin \
   -DWITH_PREFIX_CONF=/etc/centreon-engine \
   -DWITH_PREFIX_LIB=/usr/lib/centreon-engine \
   -DWITH_USER=centreon-engine \
   -DWITH_GROUP=centreon-engine \
   -DWITH_LOGROTATE_SCRIPT=1 \
   -DWITH_VAR_DIR=/var/log/centreon-engine \
   -DWITH_RW_DIR=/var/lib/centreon-engine/rw \
   -DWITH_STARTUP_DIR=/etc/init.d \
   -DWITH_PKGCONFIG_SCRIPT=1 \
   -DWITH_PKGCONFIG_DIR=/usr/lib/pkgconfig \
   -DWITH_TESTING=0

At this step, the software will check for existence and usability of the rerequisites. If one cannot be found, an appropriate error message will be printed. Otherwise an installation summary will be printed.

Note

If you need to change the options you used to compile your software, you might want to remove the CMakeCache.txt file that is in the build directory. This will remove cache entries that might have been computed during the last configuration step.

Compilation

Once properly configured, the compilation process is really simple

$ make

And wait until compilation completes.

Install

Once compiled, the following command must be run as privileged user to finish installation

$ make install

And wait for its completion.

Check-Up

After a successful installation, you should check for the existence of some of the following files.

File Description
${WITH_PREFIX_BIN}/centengine Centreon Engine daemon.
${WITH_PREFIX_BIN}/centenginestats Centreon Engine statistic.
${WITH_PREFIX_CONF}/ Centreon Engine sample configuration.
