How can I find out the version of the currently running solr

Question

Please tell me how to determine the version number of the currently running solr?

Answer 1

On the Solr Admin page, press [INFO] . The next screen will have a version.

(For me, here is the Solr administration page: http: // {host-name-or-ip}: {port} / solr / admin, I found myself dealing with an old version. Solr specification version: 1.4.0 Solr Version implementation: 1.4.0 833479)

Answer 2

With an HTTP GET request:

yoursolrhost:8983/solr/admin/info/system 

you will get the structure in many different views (xml, json, php, python, ...).

The lucene key of the structure contains version numbers.

For example, using json output:

 http://yoursolrhost:8983/solr/admin/info/system?wt=json 

The lucene key is as follows:

 "lucene": { "solr-spec-version": "4.6.0", "solr-impl-version": "4.6.0 1543363 - simon - 2013-11-19 11:16:33", "lucene-spec-version": "4.6.0", "lucene-impl-version": "4.6.0 1543363 - simon - 2013-11-19 11:05:50" }, 

Answer 3

link solr admin "infos" links to "admin / registry.jsp"

so that you can get the version with:

wget -O- " http: //solr_ip_adress.lan: 8080 / solr / admin / registry.jsp " | grep 'solr-spec-version'

Answer 4

You need to request Solr using SystemInfoHandler:

http://lucene.apache.org/solr/api/org/apache/solr/handler/admin/SystemInfoHandler.html

Answer 5

You can simply go to your Solr account page as shown in the URL

 http://localhost:8983/solr 

Answer 6

Suppose you are using version 3.6, port 8080. Go to http: // localhost: 8080 / solr / default / admin / registry.jsp

You will see the result:

 Solr Implementation Version: 3.6.0 1310449 - rmuir - 2012-04-06 11:34:07
