[ckan-dev] Installing CKAN, can't reach solr instance

Tue Aug 19 10:49:37 UTC 2014

Hi Lothar,

Good suggestion, I checked out my tomcat logs and discovered a problem with
a solr configuration file provided here -
https://github.com/ckan/ckan/wiki/How-to-Install-CKAN-2.0-on-CentOS-6.3#create-apache-solr-xml-configuration-files

<Context docBase="/usr/share/solr/apache-solr-1.4.1.war" debug="0"
privileged="true" allowLinking="true" crossContext="true">
   <Environment name="solr/home" type="java.lang.String"
value="/usr/share/solr" override="true" />
 </context>

The lower case c of 'context' closing tag didn't match the opening tag
(<Context>) so it was throwing an error. Thanks for your help.
