Follow these steps to set up a repository cluster.
By default, all Enterprise servers connected to the same database will form a repository cluster.
Follow these steps for each server in the cluster:
-
Install and configure the repository server. See the install documentation for
deploying Content Services (alfresco.war). In addition, ensure
that:
- The content store is available to all members in the cluster.
- Each cluster member must be set up to access the same database, using the same database properties as in alfresco-global.properties.
- Deploy a Solr indexing server for use across the cluster and configure the properties of each cluster member to utilize this Solr server.
- Ensure that port number 5701 (the default clustering port) is accessible on each repository server by all the other repository servers in the cluster.
-
Specify a wildcard (for example, 10.50.*.*) or exact (for
example, 192.168.1.100) IP address of the network interface for
clustering to use.
The advantage of using a wildcard IP address is that the configuration can be used on multiple servers without local changes. The java property name to use is alfresco.cluster.interface (optional).
-
(Optional) Set the following java property to activate Hazelcast’s own JMX
reporting:
hazelcast.jmx=true
-
Open the alfresco-global.properties file.
-
Set the following repository
properties.
dir.root=<ALFRESCO_HOME>/alf_data dir.remote=/nfs/or/samba/share/common/for/all/nodes dir.contentstore=${dir.remote}/contentstore dir.contentstore.deleted=${dir.remote}/contentstore.deleted dir.cachedcontent=${dir.remote}/cachedcontent -
Set the following Search properties for mutual TLS (i.e.
https).
index.subsystem.name=solr6 dir.keystore=${dir.root}/keystore (Specifies the path to the keystore file) solr.secureComms=https solr.port.ssl=8983 (Specifies the Solr load balancer SSL port) solr.host=172.31.50.59 (Specifies the Solr load balancer IP address or hostname) -
Set the following Search properties if you’re not using mutual TLS
(i.e.
http)
index.subsystem.name=solr6 solr.port=8983 (Specifies the Solr load balancer port) solr.secureComms=none (For HTTP transport between Alfresco and Solr) solr.host=172.31.50.59 (Specifies the Solr load balancer IP address or hostname)
-
Set the following repository
properties.
