Tutorial for setting up SolrCloud on Amazon EC2

Posted on by

UPDATE: This tutorial is based on Solr 4. If you want to use Solr 8, we strongly recommend to use our recent blog entry to set up Solrcloud 8 on Amazon EC2

NOTE: There is French version to this tutorial, which you’ll find on the second half of this blog entry.

In this tutorial, we’ll be installing a SolrCloud cluster on Amazon EC2.
We’ll be using Solr 4.9, Tomcat 7 and Zookeeper 3.4.6 on Debian 7 instances.
This tutorial will explain how to achieve this result.
We’ll be installing a set of 3 machines with 3 shards and 2 replicas per shard, thus creating a set of 9 shards.
We’ll also be installing a Zookeeper ensemble of 3 machines.

Binary version of SolrMeter for Solr 4

Posted on by

NOTE: English version on top, French version below.

We have noticed that in Solr 4, there is problem with the UI related to cache hit ratio evaluation of SolrMeter. Digging a bit, the problem is due to a type change between Solr 3 and Solr 4. SolrMeter expects a string, whereas Solr4 sends back a float. More precisely, Solr 4 does that within its request handler mbean, in the cache sub category.

We’re now using a patch available for this bug, created by Javier Mendez, see his contribution on this google group.

Still, there is no binary version of SolrMeter, hence this blog. Continue reading →

Integrating Solr with SPIP

Posted on by

Note: French version available at the second half of this blog entry.

Note Note: don’t hesitate to test our new open source package solution Datafari, which combines Apache ManifoldCF, Apache Solr and AjaxFranceLabs 🙂

SPIP is a well known open source platform. We wanted to share with you how to integrate graphically a Solr server with a SPIP server. The scenario is the following: you already have SPIP based web site, and you want to have a nice search functionnality based on the lastet Solr, to benefit from all its cool functionalities. You have set up a Solr, you have crawled your SPIP content, but now you want to have your Solr search in your SPIP website. This is what we present in this tutorial.

Tutorial on Authorizations for Manifold CF and Solr

Posted on by

NOTE: If you are interested in using ManifoldCF with Solr, you may want to look at our Datafari software , which combines Apache ManifoldCF with Solr, so it eases this kind of integration. The code is available on google code: https://github.com/francelabs/datafari

Manifold CF (MCF) provides a early-binding authorization mechanism for file searchs. The aim of this entry is to will describe this mechanism, and then to show you the different steps needed to configure MCF and Solr to use this fonctionnality.

MCF extracts ACLs from files at crawling-time, and injects them into Solr as specific fields for the Solr document. Continue reading →

Tutorial for combining ManifoldCF and Solr for files search

Posted on by

NOTE: If you are interested in using ManifoldCF with Solr, you may want to look at our Datafari software, which combines Apache ManifoldCF with Solr, so it eases this kind of integration. The code is available on google code: https://github.com/francelabs/datafari

With the arrival of Manifold CF 1.0 (now already in v2.5), the open source community is looking for tutorials to combine it with Solr 4. That’s the intent of this tutorial, which will drive you through the different steps required to make it work.

First, we’ll recap the installation process of Manifold CF (we’ll call it MCF later on), and of Solr. Second, we’ll configure both tools so that they can interact with each other. Third, we’ll configure MCF so that it crawls a windows file share. In this tutorial, when I specify installation directory such as solr-4.1.0, you have to complete with the absolute path of the installation directory. Continue reading →
