Apache SOLR Access Control

To add SOLR access permissions in tomcat6, follow these steps:

Edit tomcat6/Catalina/localhost/SOLR. xml

 <  Context  Docbase  = "/Var/SOLR. War"  Debug  = "0"  Privileged  = "True"  Allowlinking  = "True"  Crosscontext  = "True"  > 

 < Environment  Name  = "SOLR/home"  Type  = "Java. Lang. String"  Value  = "/Var/SOLR"  Override  = "True"  /> 

 <  Valve  Classname  = "Org. Apache. Catalina. Valves. remoteaddrvalve"  Allow = "192.168.1.100, localhost, 192.168.1.103, 127.0.0.1"  /> 

 <  Valve  Classname  = "Org. Apache. Catalina. Valves. remoteaddrvalve"  Deny  = "192.168.1.105"  /> 

 </  Context  > 

Refer to Tomcat configuration document: http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Remote_Address_Filter

To make the preceding configuration take effect, you need to re-enable the tomcat security mechanism.

Edit sudo VI/etc/default/tomcat6

Comment out the last sentenceTomcat6_security = No
