openldap备份与还原

备份

/usr/sbin/slapcat > ldapbackupfast$curday.ldif

还原（还原之前需要关闭slapd服务）

slapadd -l /data/ldapbackupfast.ldif

还原使用的是openldap底层的Berkeley DB机制，需要修改dbconfig

# Example DB_CONFIG file for use with slapd(8) BDB/HDB databases.
#
# See the Oracle Berkeley DB documentation
#   <http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/db_config.html>
# for detail description of DB_CONFIG syntax and semantics.

# Hints can also be found in the OpenLDAP Software FAQ
#    <http://www.openldap.org/faq/index.cgi?file=2>
# in particular:

# Note: most DB_CONFIG settings will take effect only upon rebuilding
# the DB environment.
