Installation¶
Centreon recommends using its official packages from the Centreon Entreprise Server (CES) repository. 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 Entreprise Server (CES). Open source products are freely available from our repository.
These packages have been successfully tested with CentOS 5 and RedHat 5.
Prerequisites¶
In order to use RPM from the CES repository, you have to install the appropriate repo file. Run the following command as privileged user
$ wget http://yum.centreon.com/standard/2.2/ces-standard.repo -O /etc/yum.repos.d/ces-standard.repo
The repo file is now installed. Don’t forget to cleanup
$ yum clean all
Install¶
Run the following commands as privileged user
$ yum install centreon-connector-perl
All dependencies are automatically installed from Centreon repositories.
Using sources¶
To build Centreon Perl Connector, you will need the following external dependencies:
- a C++ compilation environment.
- CMake (>= 2.8), a cross-platform build system.
- Centreon Clib, The centreon Core library.
- Perl, the perl library to use embedded perl.
This program is compatible only with Unix-like platforms (Linux, FreeBSD, Solaris, ...).
Prerequisites¶
CentOS¶
In CentOS you need to add manually cmake. After that you can install binary packages. Either use the Package Manager or the yum 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. |
| Centreon Clib (>= 1.0) | centreon-clib-devel | Core library used by Centreon Connector. |
| Perl | perl perl-devel (CentOS 6) perl-ExtUtils-Embed | Scripting language. Header perl (only for CentOS 6). Embedded perl (only for CentOS 6). |
Install basic compilation tools
$ yum install gcc gcc-c++ make perl $ yum install perl-devel perl-ExtUtils-Embed # Only for CentOS 6
Install Centreon repository
You need to install Centreon Entreprise Server (CES) repos file as explained Prerequisites to use some specific package version.
Install cmake
$ yum install cmake
Install Centreon Clib
See the Centreon Clib documentation.
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.
Package required to build:
| 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. |
| Centreon Clib | centreon-clib-dev | Core library used by Centreon Connector. |
| Perl | libperl-dev | Scripting language. |
Install compilation tools
$ apt-get install build-essential cmake libperl-dev
Install Centreon Clib
See the Centreon Clib documentation.
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. |
| Centreon Clib | centreon-clib-devel | Core library used by Centreon Connector. |
| Perl | perl | Scripting language. |
Install compilation tools
$ zypper install gcc gcc-c++ make cmake perl
Install Centreon Clib
See the Centreon Clib documentation.
Build¶
Get sources¶
Centreon Perl Connector can be checked out from GitHub at https://github.com/centreon/centreon-connectors . The Perl connector sources reside in the perl subdirectory. On a Linux box with git installed this is just a matter of
$ git clone https://github.com/centreon/centreon-connectors
Or You can get the latest Centreon Connector’s sources from its download website. Once downloaded, extract it
$ tar xzf centreon-connector.tar.gz
Configuration¶
At the root of the project directory you’ll find a perl/build directory which holds build scripts. Generate the Makefile by running the following command
$ cd /path_to_centreon_connector/perl/build
Your Centreon Perl Connector 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_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_PREFIX | Base directory for Centreon Perl Connector installation. If other prefixes are expressed as relative paths, they are relative to this path. | /usr/local |
| WITH_PREFIX_BINARY | Define specific directory for Centreon Connector Perl binary. | ${WITH_PREFIX}/bin |
| WITH_TESTING | Enable generation of unit tests. They can later OFF be run by typing make test. | |
Example
$ cmake \
-DWITH_PREFIX=/usr \
-DWITH_PREFIX_BINARY=/usr/lib/centreon-connector \
-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.
