SOLR Installation Type 2
These instructions have been deprecated and should not be implemented. Updated instructions will be available soon.
Since CLAIMS Direct SOLR is a pre-configured, bundled distribution of Apache SOLR, it can be deployed on any number of
nodes (individual instances). This documentation describes installation and configuration on a single node without the use of SolrCloud.
There are many scenarios for a CLAIMS Direct deployment that range from indexing the entire content of CLAIMS Direct XML to the sparse indexing of certain fields and ranges of publication dates for application-specific usage. There could also be specific QoS requirements: minimum supported queries per second, average response time, etc. All of these factors play a role in planning for a CLAIMS Direct SOLR deployment. Generally speaking, a stand-alone full index with the entire content of CLAIMS Direct XML requires, at a minimum, the following:
Basic: 6TB (SSD)
The minimum required storage allows for a full index and approximately 1-2 years of growth. It doesn't allow space for SOLR optimization (see "Commit and Optimize Operations" in Uploading Data with Index Handlers) unless carefully planned. Please contact firstname.lastname@example.org for more information about optimization with minimum requirements.
Currently, the delivery of a fully populated CLAIMS Direct index requires the above SOLR hardware requirements. A customized deployment with select data to index is currently not offered fully populated. With a custom configuration, hardware requirements are dependent on use case and complete indexing will need to be done at the installation site.
The CLAIMS Direct SOLR installation is a self-contained package suitable for deployment on any Linux server running Java 8. The simple prerequisite tool list follows:
|java||ZooKeeper, SOLR and various support tools|
|wget||Configuration tools (bootstrap-*.sh)|
|lsof||Start/stop scripts (solrctl/zookeeperctl)|
Create User asolr
It is recommended to create the user asolr.
Configuring Standalone SOLR
CLAIMS Direct SOLR uses the Apache SOLR distribution for indexing. The fully-populated delivery of the index is a single-node collection as described above. The collection name is
alexandria and although it is configurable, we recommended not changing this setting.
Your IP address allocation may be different. These are configurable in
The following variables should be configured in
|8080||The port SOLR (Jetty) should listen on and accept requests.|
|10.234.1.91||The URL to configure collections. The IP address should be the local address of the server.|
|96g||This is the java heap setting. Generally speaking, you should allocate at least 64g. The exact amount should be approximately 80% of total memory.|
The following variables need to be confirmed or set:
