What we want to get?

• Index and search all the content from Liferay• No single point of failure• Simple to manage: simple to add new machines, stop one and add

one to the cluster• As cheap as possible: No Expensive HW or software to control the

cluster.• Manage index and configuration with the same system

Configuring Zookeeper and SOLR

1. Configure the zookeeper cluster: http://zookeeper.apache.org/

2. Adapt solrconfig.xml to the new replication scenario

3. Adapt schema.xml to support Liferay

4. Configure Tomcat to connect to the zookeeper cluster

5. Start the zookeeper cluster

6. Start the SOLR Cluster

Configuring Liferay

1. Choose the right solr-web plugin, yes the one that supports zookeeper

Where we can get it?

• At the writing of this presentation, the plugin to work with zookeeper is not integrated yet with the liferay plugins head maybe in the future will end there but know you have to use this fork: https://github.com/iolalla/liferay-plugins/tree/master/webs/solr-web

• If you want to find more instructions to compile/modify the code or just the final war, please read this post: http://israelolalla.blogspot.com.es/2012/11/liferay-61-solr-4-zookeeper-massive.html

Summary

Pros:• Architecture is 100% active, all machines are

candidates for Master, in the index or search process.• 100% shared nothing architecture, no need for

network shares, NFS, etc..• We can manage the configuration files centrally.• Architecture that is self Multi Master, ie if the Master

fall, cluster itself choose the new Master.• Very efficient replication copies files and indices.

Cons:• There is a bit more RAM and CPU consumption by the

new process.
