OpenLDAP init script

The init script slapd provide start, stop and other commands for OpenLDAP daemon. It requires:

• Logger, to forward messages to syslog
• Awk, for regular expression management
• BerkeleyDB, for recover and archive tools
• OpenLDAP, for save, index, … tools

Configuration of this script can be done in an external file, with the same name as the init script in /etc/default.

A backup feature allows to save all data or configuration in an LDIF file, compressed or not. The restore feature import the last backup in the directory.

Run the script like that:

# /etc/init.d/slapd action

With action in:

• start:
  • Test configuration
  • Start slurpd if needed
  • Start slapd with data recover if needed
• stop:
  • Stop slapd and save data if needed
  • Stop slurpd if needed
• forcestop:
  • If script can read PID, do a kill -KILL PID
  • Else killall -KILL on binaries name
• restart:
  • Launch stop
  • Launch start
• force-reload:
  • Force stop
  • Config test
  • Start
• configtest: test configuration
• db_recover: data recover (slapd must be stopped)
• reindex: data index (slapd must be stopped)
• removelogs: archive old BerkeleyDB logs (slapd must be stopped)
• backup: LDIF export of all data
• restore: Remove current data and restore last backup
• backupconfig: LDIF export of configuration or copy of slapd.conf
• restoreconfig: Remove current configuration and restore last backup
• status: Display running status and naming contexts
• debug: Stop OpenLDAP and restart it in debug mode (level can be configured), with output on the console

Copy script in /etc/init.d:

# mv slapd /etc/init.d
# chmod +x /etc/init.d/slapd

Configure the service in init levels:

# ln -s /etc/init.d/slapd /etc/rc3.d/S90slapd
# ln -s /etc/init.d/slapd /etc/rc4.d/S90slapd
# ln -s /etc/init.d/slapd /etc/rc5.d/S90slapd
# ln -s /etc/init.d/slapd /etc/rc0.d/K10slapd
# ln -s /etc/init.d/slapd /etc/rc6.d/K10slapd

For RedHat based systems:

# chkconfig --add slapd

For Debian base systems:

# update-rc.d slapd defaults

Configuration file must be installed in /etc/default:

# mkdir -p /etc/default
# mv slapd.default /etc/default/slapd
# chmod 600 /etc/default/slapd

You can run several OpenLDAP daemons on the same server, and use different init scripts. For example to have a “slapd2” init script:

# ln -s /etc/init.d/slapd /etc/init.d/slapd2
# cp /etc/default/slapd /etc/default/slapd2

Use the external file in /etc/default rather than editing directly the script.
