# NAME

indexer - Indexing daemon for EPrints

# SYNOPSIS

indexer start [options]

indexer stop

indexer status

indexer --help

# DESCRIPTION

This daemon runs in the background and creates index files for all eprints repositories.

Messages and errors are logged to /opt/eprints2/var/indexer.log unless you change the log options. If it appears to be having problems try raising the log level and examining the log.

Once every 24 hours, the indexer rolls the logs (up to logfile.5) and then starts again. See --rollcount for ways to customise this.

# OPTIONS

--help

  Print a brief help message and exit.

--man

  Print the full manual page and then exit.

--quiet

  Be vewwy vewwy quiet. This option will supress all output unless an error occurs.

--force

  Start up, even if the PID file exists (implying another copy is running). This is useful for starting after a crash, but be carefully not to run to copies at once as BAD THINGS will happen.

--verbose

  Explain in detail what is going on. May be repeated for greater effect.

--logfile filename

  Log to filename rather than default indexer log.

--loglevel level

  Set the level of detail to log. Level may be 0-5.

--rollcount number

  Set the number of once-through logs that should be kept. If set to zero then indexer will never roll the logs but rather just keep writing to the main log.

--notdaemon

  Do not become a daemon, remain attached to the current terminal.

  Log goes to STDERR instead of the log file.

  Does not create a .pid file.

--once

  Only clear the current queue of things needing indexing then exit.

--version

  Output version information and exit.

# Making into a service

This has only been tested under redhat linux. It make work on other OS's, but not promise.

To make the indexer into a service which starts and stops on reboots etc. like httpd and mysqld do the following (as root):

     ln -s /opt/eprints2/bin/epindexer /etc/init.d/epindexer
     chkconfig --add epindexer
     chkconfig epindexer on

The epindexer script runs as root, changes user to ``eprints'' (or whatever uid your eprints install runs as) and then calls indexer.
