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.
Using packages¶
Centreon provides RPM for its products through Centreon Open Sources (ex CES). Open source products are freely available from our repository. These packages are available for CentOS 6 or 7 architeture x86_64, which is the sole platform officially supported by Centreon.
Prerequisites¶
In order to use RPM from the COS repository, you have to install the appropriate repo file. Run the following command as privileged user
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.el6.noarch.rpm
$ yum clean all
Install¶
Run the following commands as privileged user
$ yum install centreon-clib centreon-clib-devel
All dependencies are automatically installed from Centreon repositories.
Using sources¶
To build Centreon Clib, you will need the following external dependencies:
- a C++ compilation environment
- CMake (>= 2.8), a cross-platform build system
This program is compatible only with Unix-like platforms (Linux, FreeBSD, Solaris, ...).
Prerequisites¶
CentOS¶
Either use the Package Manager or the yum tool to install them. You should check package versions when necessary.
Required packages:
| Software | Package Name | Description |
|---|---|---|
| C++ compilation environment | gcc gcc-c++ make | Mandatory tools to compile |
| CMake (>= 2.8) | cmake | Read the build script and prepare sources for compilation |
Install basic compilation tools:
$ yum install gcc gcc-c++ make cmake
Debian/Ubuntu¶
In recent Debian/Ubuntu versions, necessary software is available as binary packages from distribution repositories. Either use the Package Manager or the apt-get tool to install them. You should check packages version when necessary.
Required packages:
| Software | Package Name | Description |
|---|---|---|
| C++ compilation environment | build-essential | Mandatory tools to compile. |
| CMake (>= 2.8) | cmake | Read the build script and prepare sources for compilation. |
Install compilation tools:
$ apt-get install build-essential cmake
OpenSUSE¶
In recent OpenSUSE versions, necessary software is available as binary packages from OpenSUSE repositories. Either use the Package Manager or the zypper tool to install them. You should check packages version when necessary.
Package required to build:
| Software | Package Name | Description |
|---|---|---|
| C++ compilation environment | gcc gcc-c++ make | Mandatory tools to compile. |
| CMake (>= 2.8) | cmake | Read the build script and prepare sources for compilation. |
Install compilation tools
$ zypper install gcc gcc-c++ make cmake
Build¶
Get sources¶
Centreon Clib can be checked out from GitHub at https://github.com/centreon/centreon-clib. Currently, only the 1.4 branch works with Centreon components. On a Linux box with git installed this is just a matter of
$ git clone -b 1.4 https://github.com/centreon/centreon-clib
Or You can get the latest Centreon Clib’s sources from its download website Once downloaded, extract it
$ tar xzf centreon-clib.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_clib/build
Your Centreon Clib 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_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 Clib installation. If other prefixes are expressed as relative paths, they are relative to this path. | /usr/local |
| 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_SHARED_LIB | Create or not a shared library. | ON |
| WITH_STATIC_LIB | Create or not a static library. | OFF |
| WITH_TESTING | Build unit test. | OFF |
Example
$ cmake \
-DWITH_TESTING=0 \
-DWITH_PREFIX=/usr \
-DWITH_PREFIX_LIB=/usr/lib \
-DWITH_PREFIX_INC=/usr/include/centreon-clib \
-DWITH_SHARED_LIB=1 \
-DWITH_STATIC_LIB=0 \
-DWITH_PKGCONFIG_DIR=/usr/lib/pkgconfig .
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.
