Centos Multimaster replicating

on
Bismillah,
its supposed to post this article a few months ago
here I will explain about centos multimaster replicating. first the scenario, you have two server as a High Availability for LDAP server. before we do a replication make sure both server can connect each other.
please setup you hostname.
1st server:
hostname = kura1.com
ip-addr = 10.10.10.202

2nd server:
hostname = kura2.com
ip-addr = 10.10.10.16

make sure at /etc/hosts have this. or at your DNS server.
install the package at 1st server:

I'm using Centos 5.8 as a server. 
yum install centos-ds* --enablerepo=extras
build the directory server. 
setup-ds.pl
my database name is slapd-kura1
my Directory Manager password is secret
fill the Directory Manager password,
1. create replication manager, copy this and named as 1_replicating_manager.ldif put in /tmp/ 
dn: cn=replication manager,cn=config
objectclass: inetorgperson
objectclass: person
objectclass: top
objectclass: organizationalPerson
cn: replication manager
sn: replication manager
userpassword: password
nsIdleTimeout: 0
next import that file. 
cd /usr/lib64/slapd/slapd-kura1/
sh ldif2ldap -D "Directory Manager" secret /tmp/1_replicating_manager.ldif
2. create changelog dir, save as 2_change_log.ldif 
dn: cn=changelog5,cn=config
objectclass: top
objectclass: extensibleObject
cn: changelog5
nsslapd-changelogdir: /var/lib/dirsrv/slapd-kura1/changelogdb
nsslapd-changelogmaxage: 10d
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/2_change_log.ldif
3. create replica task, save as /tmp/3_replica_task.ldif 
dn: cn=replica,cn=dc\3Dkura1\, dc\3Dcom,cn=mapping tree,cn=config
nsDS5ReplicaType: 3
cn: replica
nsDS5ReplicaBindDN: cn=replication manager,cn=config
nsds5ReplicaPurgeDelay: 604800
nsDS5ReplicaRoot: dc=kura1, dc=com
nsDS5ReplicaId: 8
objectClass: extensibleObject
objectClass: top
objectClass: nsDS5Replica
nsds5ReplicaChangeCount: 1
nsDS5Flags: 1
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/3_replica_task.ldif
4. create replica agreement from 202 to 16, save as /tmp/4_replica_agreement.ldif 
dn: cn=XX202-XX202toXX016,cn=replica,cn=dc\3Dkura1\, dc\3Dcom,cn=mapping tree,cn=config
cn: XX202-XX202toXX016
nsDS5ReplicaBindDN: cn=replication manager,cn=config
description: from XX202 to XX016
nsDS5ReplicaRoot: dc=kura1, dc=com
nsDS5ReplicaHost: kura2.com
nsDS5ReplicaPort: 389
nsDS5ReplicaBindMethod: SIMPLE
objectClass: top
objectClass: nsDS5ReplicationAgreement
nsDS5ReplicaCredentials: password
nsDS5ReplicaTransportInfo: LDAP
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/4_replica_agreement.ldif
5. run the replication, save as /tmp/5_replica_run.ldif 
dn: cn=XX202-XX202toXX016, cn=replica,cn="dc=kura1, dc=com", cn=mapping tree,cn=config
changetype: modify
add: nsds5BeginReplicaRefresh
nsds5BeginReplicaRefresh: start
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/5_replica_run.ldif
For second server do same step, the differences only at step 2,3,4,5 like this. 2. create changelog dir, save as 2_2_change_log.ldif 
dn: cn=changelog5,cn=config
objectclass: top
objectclass: extensibleObject
cn: changelog5
nsslapd-changelogdir: /var/lib/dirsrv/slapd-kura2/changelogdb
nsslapd-changelogmaxage: 10d
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/2_2_change_log.ldif
3. create replica task, save as /tmp/3_2_replica_task.ldif 
dn: cn=replica,cn=dc\3Dkura2\, dc\3Dcom,cn=mapping tree,cn=config
nsDS5ReplicaType: 3
cn: replica
nsDS5ReplicaBindDN: cn=replication manager,cn=config
nsds5ReplicaPurgeDelay: 604800
nsDS5ReplicaRoot: dc=kura2, dc=com
nsDS5ReplicaId: 8
objectClass: extensibleObject
objectClass: top
objectClass: nsDS5Replica
nsds5ReplicaChangeCount: 1
nsDS5Flags: 1
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/3_2_replica_task.ldif
4. create replica agreement from 16 to 202, save as /tmp/4_2_replica_agreement.ldif 
dn: cn=XX016-XX016toXX202,cn=replica,cn=dc\3Dkura2\, dc\3Dcom,cn=mapping tree,cn=config
cn: XX016-XX016toXX202
nsDS5ReplicaBindDN: cn=replication manager,cn=config
description: from XX016 to XX202
nsDS5ReplicaRoot: dc=kura2, dc=com
nsDS5ReplicaHost: kura1.com
nsDS5ReplicaPort: 389
nsDS5ReplicaBindMethod: SIMPLE
objectClass: top
objectClass: nsDS5ReplicationAgreement
nsDS5ReplicaCredentials: password
nsDS5ReplicaTransportInfo: LDAP
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/4_2_replica_agreement.ldif
5. run the replication, save as /tmp/5_2_replica_run.ldif 
dn: cn=XX016-XX016toXX202, cn=replica,cn="dc=kura2, dc=com", cn=mapping tree,cn=config
changetype: modify
add: nsds5BeginReplicaRefresh
nsds5BeginReplicaRefresh: start
import: 
sh ldif2ldap -D "Directory Manager" secret /tmp/5_2_replica_run.ldif
