Installation¶

Centreon recommends using its official packages from the Centreon Open Sources version available free of charge on our repository (ex CES). Most of Centreon endorsed software are available as RPM packages.

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¶

Centreon provides RPM for its products through Centreon Open Sources (COS) version available free of charge on our repository, Open source products are freely available from our repository.

These packages are available for CentOS 6 and 7 version.

Prerequisites¶

In order to use RPM from the COS repository, you have to install the appropriate repository.

CentOS 6¶

Run the following commands as privileged user

$ wget http://yum.centreon.com/standard/3.4/el6/stable/noarch/RPMS/centreon-release-3.4-4.el6.noarch.rpm
$ yum install --nogpgcheck -y centreon-release-3.4-4.el6.noarch.rpm
$ rm -f centreon-release-3.4-4.el6.noarch.rpm
$ yum clean all

CentOS 7¶

Run the following commands as privileged user

$ wget http://yum.centreon.com/standard/3.4/el7/stable/noarch/RPMS/centreon-release-3.4-4.el7.centos.noarch.rpm
$ yum install --nogpgcheck -y centreon-release-3.4-4.el7.centos.noarch.rpm
$ rm -f centreon-release-3.4-4.el7.centos.noarch.rpm
$ yum clean all

Install¶

Run the following commands as privileged user

$ yum install centreon-broker centreon-broker-core centreon-broker-cbd centreon-broker-cbmod centreon-broker-storage

All dependencies are automatically installed from Centreon repositories.

Using sources¶

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

a C++ compilation environment.
CMake (>= 2.8), a cross-platform build system.
the Qt (>= 4.7.4) framework with QtCore, QtSql and QtXml modules.
RRDTool development files (for the RRD module).
GnuTLS (>= 2.8), a secure communications library.

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

Prerequisites¶

If you decide to build Centreon Broker 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-broker are as follow (need to run these as root)

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

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 Broker can be checked out from GitHub at https://github.com/centreon/centreon-broker. On a Linux box with git installed run this

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

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

$ tar xzf centreon-broker.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 commands

$ cd /path_to_centreon_broker/build
$ cmake .

Note

If you are using Debian Stretch or Ubuntu Xenial, you need set some flags to build source compatible with the new compile tools. For this, set the variable CXXFLAGS and compile as show bellow

$ cd /path_to_centreon_broker/build
$ export CXXFLAGS="-std=c++98 -Wno-long-long"
$ cmake .

Your Centreon Broker 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_DAEMONS	Set a list of Centreon Broker sysv start up script.	OFF
WITH_GROUP	Set the group for Centreon Broker installation.	root

WITH_USER	Set the user for Centreon Broker installation.	root

Example

$ cmake \
    -DWITH_DAEMONS='central-broker;central-rrd' \
    -DWITH_GROUP=centreon-broker \
    -DWITH_PREFIX=/usr \
    -DWITH_PREFIX_BIN=/usr/sbin \
    -DWITH_PREFIX_CONF=/etc/centreon-broker \
    -DWITH_PREFIX_INC=/usr/include/centreon-broker \
    -DWITH_PREFIX_LIB=/usr/lib/nagios \
    -DWITH_PREFIX_MODULES=/usr/share/centreon/lib/centreon-broker \
    -DWITH_PREFIX_VAR=/var/lib/centreon-broker \
    -DWITH_STARTUP_DIR=/etc/init.d \
    -DWITH_STARTUP_SCRIPT=auto \
    -DWITH_TESTING=0 \
    -DWITH_USER=centreon-broker .

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.
