I have implemented cluster setup as depicted in </SPAN><A href="https://wiki.alfresco.com/wiki/File:Alfresco_LB_Diagram.png" rel="nofollow noopener noreferrer">https://wiki.alfresco.com/wiki/File:Alfresco_LB_Diagram.png</A><SPAN>. I have used alfresco+tomcat bundle here for this setup but hope this works for any application server.</SPAN><BR /><BR /><SPAN>Target environment/components:</SPAN><BR /><SPAN>1. Alfresco 3.4.6 Enterprise.</SPAN><BR /><SPAN>2. Red Hat Enterprise Linux ver. 5.5</SPAN><BR /><SPAN>3. JDK 1.6</SPAN><BR /><SPAN>5. MySQL 5.1</SPAN><BR /><SPAN>6. Apache 2.2 (Load Balancer)</SPAN><BR /><SPAN>7. Tomcat 6.0</SPAN><BR /><BR /><SPAN>Cluster components:</SPAN><BR /><SPAN>1. Common Database (too clustered)</SPAN><BR /><SPAN>2. Common Content Store (On SAN)</SPAN><BR /><SPAN>3. Individual indices &amp; cache</SPAN><BR /><BR /><SPAN>I have followed below steps to achieve the same. </SPAN><BR /><BR /><SPAN>NOTE: Apache is used as load balancer.</SPAN><BR /><BR /><SPAN>1. Installed alfresco 3.4.6 on server1.</SPAN><BR /><SPAN>2. After installation updated /tomcat/shared/classes/alfresco-global.properties for setting up cluster for server1.</SPAN><BR /><SPAN>3. Now for server1, i have indexes created locally under alf_data for server1; content store for server1 is mounted on a SAN @ /mysan/alfresco/my_content_store. </SPAN><BR /><SPAN>4. DB for server1 is configured at other server @ jdbc:mysql://&lt;DB IP&gt;:3306/alfresco.</SPAN><BR /><SPAN>5. Updated index.recovery.mode=AUTO for cluster setup. Sample properties are</SPAN><BR /><BLOCKQUOTE class="jive-quote">index.recovery.mode=AUTO<BR /><BR />dir.root=/mysan/alfresco/my_content_store<BR />dir.contentstore=${dir.root}/contentstore<BR />dir.contentstore.deleted=${dir.root}/contentstore.deleted<BR />dir.auditcontentstore=${dir.root}/audit.contentstore<BR /><BR />dir.indexes=/usr/local/softwares/alfresco/alf_data/lucene-indexes<BR />dir.indexes.backup=/usr/local/softwares/alfresco/alf_data/backup-lucene-indexes<BR />dir.indexes.lock=/usr/local/softwares/alfresco/alf_data/locks<BR /><BR />alfresco.cluster.name=my-cluster<BR />alfresco.tcp.initial_hosts=&lt;IP 1&gt;[7800],&lt;IP 2&gt;[7800]<BR />alfresco.jgroups.defaultProtocol=TCP<BR /><BR />db.driver=org.gjt.mm.mysql.Driver<BR />db.username=admin<BR />db.password=admin<BR />db.name=alfresco<BR />db.url=jdbc:mysql://&lt;DB IP&gt;:3306/alfresco<BR />hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect</BLOCKQUOTE><SPAN>6.

After installation updated /tomcat/shared/classes/alfresco-global.properties for setting up cluster for server2 as below.</SPAN><BR /><SPAN>10. Now for server2, i have indexes created locally under alf_data for server2;content store is mounted on a SAN @ /mysan/alfresco/my_content_store and db for server2 @ jdbc:mysql://&lt;DB IP&gt;:3306/alfresco. </SPAN><BR /><SPAN>11. Updated index.recovery.mode=AUTO. Below are sample properties for server2 in cluster.</SPAN><BR /><BLOCKQUOTE class="jive-quote">index.recovery.mode=AUTO<BR /><BR />dir.root=/mysan/alfresco/alf_dat_auth<BR />dir.contentstore=${dir.root}/contentstore<BR />dir.contentstore.deleted=${dir.root}/contentstore.deleted<BR />dir.auditcontentstore=${dir.root}/audit.contentstore<BR /><BR />dir.indexes=/usr/local/softwares/alfresco/alf_data/lucene-indexes<BR />dir.indexes.backup=/usr/local/softwares/alfresco/alf_data/backup-lucene-indexes<BR />dir.indexes.lock=/usr/local/softwares/alfresco/alf_data/locks<BR /><BR />alfresco.cluster.name=my-cluster<BR />alfresco.tcp.initial_hosts=&lt;IP 1&gt;[7800],&lt;IP 2&gt;[7800]<BR />alfresco.jgroups.defaultProtocol=TCP<BR /><BR />db.driver=org.gjt.mm.mysql.Driver<BR />db.username=admin<BR />db.password=admin<BR />db.name=alfresco<BR />db.url=jdbc:mysql://&lt;DB IP&gt;:3306/alfresco<BR />hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect</BLOCKQUOTE><SPAN>12. Started server2 &amp; logged into explorer/share, its working fine. It may take some time due to index updates for cluster.</SPAN><BR /><SPAN>13. Restarted server1. I can access both servers simultaneously.</SPAN><BR /><SPAN>14. No error till now so assuming both server1 &amp; server2 are fine and a cluster has been setup.</SPAN><BR /><SPAN>15. Tested setup as per </SPAN><A href="http://wiki.alfresco.com/wiki/Cluster_Configuration_V2.1.3_and_Later#Testing_the_cluster" rel="nofollow noopener noreferrer">http://wiki.alfresco.com/wiki/Cluster_Configuration_V2.1.3_and_Later#Testing_the_cluster</A><SPAN>.</SPAN><BR /><SPAN>16. Tested Cache clustering, Index clustering &amp; Content replication/sharing. Working fine as i can see content updated on one server is reflected on other server.</SPAN><BR /><SPAN>17. High Availability is maintained by load balancer which takes care of incoming requests &amp; forwards them to current active node at any time.</SPAN><BR /><BR /><SPAN>All set for this cluster. More servers can be added as per need. Its working perfectly.</SPAN></BODY></HTML> Tue, 28 Feb 2012 10:40:32 GMT dynamolalit 2012-02-28T10:40:32Z Alfresco cluster configuration on RHEL. https://connect.hyland.com/t5/alfresco-archive/alfresco-cluster-configuration-on-rhel/m-p/268691#M221821 Hi All,I am sharing my experience in clustering here which i have earned during one of my implementations.
