Populating Slaves
One of the most difficult tasks of establishing a replicant is ensuring that it
starts with an identical database to it's master. Possibly the simplest way to
establish replica slaves is as follows:
1. Ensure there is a dn with which one can bind the the master and view all attributes
and objects in the Dit.
2. Temporarily modify the query result size limit* of the master to permit the entire
database to be downloaded (the sizelimit parameter in slapd.conf) and restart the
master slapd.
3. Set the default base, updatedn, etc... on the slave
4. Ensure schema files on master and slave are identical.
Tip: slave:/etc/openldap/schema $ scp root@master:/etc/openldap/schema/* .
5. Define the slave replicant on the master and re-apply size-limit, but do not restart the
master slapd (yet). Ensure that the replication log file exists with correct permissions.
6. Copy the database to the slave:
ldapsearch -LLL -D”bind dn” -w “bind password” “objectclass=*” | slapadd -n 1
7. Start the slave slapd.
8. Restart the master slapd.
*This procedure may not be appropriate for very large databases.
