i always wanted to try this. was following this article: http://wiki.alfresco.com/wiki/Configuring_JGroups_and_Alfresco_Clustersthese are my steps:Installation of cluster and configuration of jgroups1. first step: synchronize time on both nodes. Difference must not be larger than ~5 second21 Aug 21:14:50 ntpdate[4806]: step time server 91.189.94.4 offset 10.524274 sec
… interesting2. Install alfresco on node1. 3. Configure contentstore. contentstore muste be shared. indices never be shared.- configure share drive (nfs) for contentstore
- Configure dir.root to shared folder
- alfresco-global.properties : dir.root=/mnt/alf_data (shared folder)
- separate indices from dir.root
- Configure dir.indexes to local folder (outside dir.root)
- alfresco-global.properties : dir.indexes=/export/indices/lucene-indexes
- configure cluster:
- alfresco-global.properties : alfresco.cluster.name=testcluster
4. configure remote access for mysql.5. Install alfresco on node2- repeat step 3
- configure db.url pointing to node1
6. configure indexing - alfresco-global.properties : index.recovery.mode=AUTO
- alfresco-global.properties : index.tracking.cronExpression=0/5 * * * * ?
- alfresco-global.properties : index.tracking.reindexLagMs=10000
7. enable ehcache configuration- cd /opt/alfresco-3.4.d/tomcat/shared/classes/alfresco/extension/
- cp ehcache-custom.xml.sample.cluster ehcache-custom.xml
8. change cacheManagerPeerProviderFactory in ehcache-custom.xml<cacheManagerPeerProviderFactory
class="org.alfresco.repo.cache.AlfrescoCacheManagerPeerProviderFactory"
properties="heartbeatInterval=5000,
peerDiscovery=automatic,
multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446" />
9. configure ehcache on both nodes:- alfresco-global.properties : alfresco.jgroups.defaultProtocol=TCP
- alfresco-global.properties : alfresco.jgroups.bind_address=node1
- alfresco-global.properties : alfresco.jgroups.bind_interface=eth0
- alfresco-global.properties : alfresco.tcp.start_port=7800
- alfresco-global.properties : alfresco.tcp.port_range=5
- alfresco-global.properties : alfresco.tcp.initial_hosts=node1[7800],node2[7800]
- alfresco-global.properties : alfresco.ehcache.rmi.hostname=nodeX
- alfresco-global.properties : alfresco.rmi.services.external.host=nodeX
- alfresco-global.properties : alfresco.ehcache.rmi.port=40001
- alfresco-global.properties : alfresco.ehcache.rmi.remoteObjectPort=45001
10. test content sharing - login to node1/alfresco
- create new space/folder
- upload document to space/folder
- login to node2/alfresco
- check if uploaded document and newly created space/folder is available
that works!11. test index synchronization - login to node1/alfresco
- change metadata of any file
- login to node2/alfresco
- check if metadata has been changed
that does not work.index is not being synchronized unless server is restarted. On restart the indexer will notice that content/metadata has been changed an will index it.when starting i receive a exception (see second post…) which i dont understand. also when i access nodes the exception is thrown.
