Version 3.0.0 of the QCG-Computing service introduced some major changes in files and configuration layout, namely:
- the layout of the directories adheres now general packages guidances, i.e. service is not installed anymore in /opt/plgrid but in standard paths (whit a few minor exceptions):
- configuration is now stored in /etc/qcg/qcg-comp/,
- logs can be found in /var/log/qcg/qcg-comp/,
- the service and client binaries can be found in /usr/sbin/ and /usr/bin respectively.
- the 5.X Globus packages from EPEL/IGE repository are used (instead of providing it qcg-dep packaged),
- the service can use the host certificate and key from standard location (i.e. /etc/grid-security),
- the service can listen on standard 443 (HTTPs port),
- optional integration with VOMS infrastructure.
This guide aims to help with migration from 2.X version.
