Creating a standalone binary
We provide a script to prepare standalone binary of the unified agent. It uses several Perl dependencies :
- PAR::Packer
- XML::SAX::EXPAT
- Net::IP
- Digest::MD5
- Getopt::Long
We suggest you to use cpan to install it.
#cpan cpan shell -- CPAN exploration and modules installation (v1.7602) ReadLine support enabled cpan> install PAR::Packer cpan> intall XML::SAX::Expat cpan> install Net::IP cpan> install Digest::MD5 cpan> install Getopt::Long
Then you'll be able to use the script itself from the official archive:
gunzip Ocsinventory-Agent-XXXXXXX.tar.gz # Not needed with a recent GNU tar tar xf Ocsinventory-Agent-XXXXXXX.tar cd Ocsinventory-Agent-XXXXXXX/ $./tools/standalone.sh ocsinventory-agent.bin generated!
The binary is ocsinventory-agent.bin
Creating a 'truly' standalone binary
A way to create a truly standalone binary (but _not_ architecture indepent), truly in this case means that there's no need to install the perl libraries from the agent on the box that will be running the agent.
NOTE: The only thing remaining is telling PAR to also include the system libraries needed by Compress::Zlib, Net::SSLeay among others
Compiling the agent
Follow the above steps to create the binary (but don't install install it). Once it is build there's some editing to be done:
Logging
Modify the Ocsinventory-Agent-0.0.10beta2/lib/Ocsinventory/Logger.pm file to always include it's logging backends:
package Ocsinventory::Logger; # TODO use Log::Log4perl instead. ### Include all Logger Backends so PAR will know about them use Ocsinventory::LoggerBackend::Stderr; use Ocsinventory::LoggerBackend::Syslog; use Ocsinventory::LoggerBackend::File; use Carp;
Network
Modify the Ocsinventory-Agent-0.0.10beta2/lib/Ocsinventory/Agent/Network.pm file to always include modules needed
package Ocsinventory::Agent::Network; # TODO: # - set the correct deviceID and olddeviceID use strict; use warnings; use LWP::UserAgent; use Ocsinventory::Compress;
Backend
Modify the Ocsinventory-Agent-0.0.10beta2/lib/Ocsinventory/Agent/Backend.pm file to always include all backends
package Ocsinventory::Agent::Backend; use strict; no strict 'refs'; use warnings; use ExtUtils::Installed; ### Include required modules use Net::SSLeay; use XML::SAX::Expat; use Proc::Daemon; ### Include available XML Responses use Ocsinventory::Agent::XML::Response::Inventory; use Ocsinventory::Agent::XML::Response::Prolog; ### Include available backends use Ocsinventory::Agent::Backend::DeviceID; use Ocsinventory::Agent::Backend::OS::Linux; use Ocsinventory::Agent::Backend::OS::Generic::Screen; use Ocsinventory::Agent::Backend::OS::Generic::Dmidecode::Memory; use Ocsinventory::Agent::Backend::OS::Generic::Dmidecode::Ports; use Ocsinventory::Agent::Backend::OS::Generic::Dmidecode::Slots; use Ocsinventory::Agent::Backend::OS::Generic::Dmidecode::Bios; use Ocsinventory::Agent::Backend::OS::Generic::Dmidecode; use Ocsinventory::Agent::Backend::OS::Generic::Hostname; use Ocsinventory::Agent::Backend::OS::Generic::Lspci::Modems; use Ocsinventory::Agent::Backend::OS::Generic::Lspci::Sounds; use Ocsinventory::Agent::Backend::OS::Generic::Lspci::Controllers; use Ocsinventory::Agent::Backend::OS::Generic::Lspci::Videos; use Ocsinventory::Agent::Backend::OS::Generic::Users; use Ocsinventory::Agent::Backend::OS::Generic::Packaging; use Ocsinventory::Agent::Backend::OS::Generic::Ipmi; use Ocsinventory::Agent::Backend::OS::Generic::Lspci; use Ocsinventory::Agent::Backend::OS::Generic::Packaging::Deb; use Ocsinventory::Agent::Backend::OS::Generic::Packaging::Gentoo; use Ocsinventory::Agent::Backend::OS::Generic::Packaging::RPM; use Ocsinventory::Agent::Backend::OS::Linux::Domains; use Ocsinventory::Agent::Backend::OS::Linux::Archs::PowerPC; use Ocsinventory::Agent::Backend::OS::Linux::Storages; use Ocsinventory::Agent::Backend::OS::Linux::Uptime; use Ocsinventory::Agent::Backend::OS::Linux::Network::IPv4; use Ocsinventory::Agent::Backend::OS::Linux::Network::Networks; use Ocsinventory::Agent::Backend::OS::Linux::CPU; use Ocsinventory::Agent::Backend::OS::Linux::Storages::HP; use Ocsinventory::Agent::Backend::OS::Linux::Storages::3ware; use Ocsinventory::Agent::Backend::OS::Linux::Storages::Lsilogic; use Ocsinventory::Agent::Backend::OS::Linux::Storages::Adaptec; use Ocsinventory::Agent::Backend::OS::Linux::Sounds; use Ocsinventory::Agent::Backend::OS::Linux::Drives; use Ocsinventory::Agent::Backend::OS::Linux::Controllers; use Ocsinventory::Agent::Backend::OS::Linux::Mem; use Ocsinventory::Agent::Backend::OS::Linux::Sys; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Redhat; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Ubuntu; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Fedora; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Slackware; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Gentoo; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Debian; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Mandriva; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Mandrake; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Knoppix; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::Trustix; use Ocsinventory::Agent::Backend::OS::Linux::Distro::NonLSB::SuSE; use Ocsinventory::Agent::Backend::OS::Linux::Distro::LSB; use Ocsinventory::Agent::Backend::OS::Generic; use Ocsinventory::Agent::Backend::IpDiscover::Nmap; use Ocsinventory::Agent::Backend::IpDiscover::IpDiscover; use Ocsinventory::Agent::Backend::AccessLog; use Ocsinventory::Agent::Backend::IpDiscover; use Ocsinventory::Agent::Backend::OS::Linux;
Create standalone binary
Now you can compile the standalone binary again, only this time it has all the required modules included:
pp -B -c -o ocsinventory-agent.bin ocsinventory-agent
TODO
Include libraries (.so) required by some modules.
