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 in an LDIF file, compressed or not.

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-realod:
  • 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
• status: Display running status and naming contexts

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:

# cp /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.
