Replication 如何配置ldap一从多主复制

我刚刚成功地复制了Openldap，使用Ubuntu10.04作为主提供者，12.04作为从使用者

我正在使用syncrepl方法进行此复制

下面是provider.ldif和consumer.ldif的配置

### provider ###
# Add indexes to the frontend db.
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryCSN eq
-
add: olcDbIndex
olcDbIndex: entryUUID eq

#Load the syncprov and accesslog modules.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov
-
add: olcModuleLoad
olcModuleLoad: accesslog

# Accesslog database definitions
dn: olcDatabase={2}hdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcHdbConfig
olcDatabase: {2}hdb
olcDbDirectory: /var/lib/ldap/accesslog
olcSuffix: cn=accesslog
olcRootDN: cn=admin,dc=teleneos,dc=org
olcDbIndex: default eq
olcDbIndex: entryCSN,objectClass,reqEnd,reqResult,reqStart

# Accesslog db syncprov.
dn: olcOverlay=syncprov,olcDatabase={2}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE
olcSpReloadHint: TRUE

# syncrepl Provider for primary db
dn: olcOverlay=syncprov,olcDatabase={1}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE

# accesslog overlay definitions for primary db
dn: olcOverlay=accesslog,olcDatabase={1}hdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcAccessLogConfig
olcOverlay: accesslog
olcAccessLogDB: cn=accesslog
olcAccessLogOps: writes
olcAccessLogSuccess: TRUE
# scan the accesslog DB every day, and purge entries older than 7 days
olcAccessLogPurge: 07+00:00 01+00:00

### consumer ###
#Load the syncprov module.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov

# syncrepl specific indices
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryUUID eq
-
add: olcSyncRepl
olcSyncRepl: rid=0 provider=ldap://192.168.2.29 bindmethod=simple binddn="cn=admin,dc=teleneos,dc=org" 
 credentials=teleneos searchbase="dc=teleneos,dc=org" logbase="cn=accesslog" 
 logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on 
 type=refreshAndPersist retry="60 +" syncdata=accesslog
-
add: olcUpdateRef
olcUpdateRef: ldap://192.168.2.29

然后低于consumer.ldif

### provider ###
# Add indexes to the frontend db.
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryCSN eq
-
add: olcDbIndex
olcDbIndex: entryUUID eq

#Load the syncprov and accesslog modules.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov
-
add: olcModuleLoad
olcModuleLoad: accesslog

# Accesslog database definitions
dn: olcDatabase={2}hdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcHdbConfig
olcDatabase: {2}hdb
olcDbDirectory: /var/lib/ldap/accesslog
olcSuffix: cn=accesslog
olcRootDN: cn=admin,dc=teleneos,dc=org
olcDbIndex: default eq
olcDbIndex: entryCSN,objectClass,reqEnd,reqResult,reqStart

# Accesslog db syncprov.
dn: olcOverlay=syncprov,olcDatabase={2}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE
olcSpReloadHint: TRUE

# syncrepl Provider for primary db
dn: olcOverlay=syncprov,olcDatabase={1}hdb,cn=config
changetype: add
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: syncprov
olcSpNoPresent: TRUE

# accesslog overlay definitions for primary db
dn: olcOverlay=accesslog,olcDatabase={1}hdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcAccessLogConfig
olcOverlay: accesslog
olcAccessLogDB: cn=accesslog
olcAccessLogOps: writes
olcAccessLogSuccess: TRUE
# scan the accesslog DB every day, and purge entries older than 7 days
olcAccessLogPurge: 07+00:00 01+00:00

### consumer ###
#Load the syncprov module.
dn: cn=module{0},cn=config
changetype: modify
add: olcModuleLoad
olcModuleLoad: syncprov

# syncrepl specific indices
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
olcDbIndex: entryUUID eq
-
add: olcSyncRepl
olcSyncRepl: rid=0 provider=ldap://192.168.2.29 bindmethod=simple binddn="cn=admin,dc=teleneos,dc=org" 
 credentials=teleneos searchbase="dc=teleneos,dc=org" logbase="cn=accesslog" 
 logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on 
 type=refreshAndPersist retry="60 +" syncdata=accesslog
-
add: olcUpdateRef
olcUpdateRef: ldap://192.168.2.29

这是成功复制的，当我在提供者上添加值时，将在使用者从属服务器上复制。但这只连接了2台计算机。如果我有10台以上的计算机作为providermaster，该如何处理。是否应在customer.ldif上添加olcUpdateRef:ldap://url_ldap 一个接一个

 add: olcUpdateRef
olcUpdateRef: ldap://192.168.2.29
olcUpdateRef: ldap://192.168.2.30
olcUpdateRef: ldap://192.168.2.31
...
...

olcUpdateRef: ldap://192.168.2.39

这种情况下还有其他配置吗？我认为，如果我添加一个接一个的ldap主url，我将不会有效

帮我解决这个问题

谢谢

我不清楚这是一个受支持的配置还是可以工作，但如果是这样的话，您所需要的只是消费者中的多个syncrepl指令

注意：您不应该在使用者中加载syncprov模块。

但是，我的模式可能吗？有关于这方面的配置示例或参考吗？
