Introduction

This page describes the general scheme how xrootd software an configuration files are installed and distributed at SLAC.

Taylor is used to distribute xrootd releases to the data servers and redirectors.

Distributing the xrootd tgz files.

Xrootd release are kept as tgz files in the distribution directory

/afs/slac/package/xrd/distrib/xrootd/releases/

The tgz files contain the compiled xrootd release and the file names use the structure
xrootd-<releaseDate>_<arch>_dbg.tgz where <releaseDate> is the xrootd version and the format of the date is YYYYMMDD-HHMM and <arch> is the architecture the release was build for.

When Taylor runs on an xrootd server it finds all release that matches the architecture of the local host and if will untar the release to the /opt/xrootd directory if the
release has not yet been installed. This means that all release that are available in the distribution directory are also available on an xrootd server.
