My versions:
CentOS 6.5 x86_64 kvm
Java 1.7.0_65
Solr 4.9.0
Tomcat6.0.24
I'm still learning on how to install Solr for my Drupal installation. Been following a few tutorials on getting this set up. Java and Tomcat work right now. I opened up the port 8080 on my iptables so :8080 loads the Tomcat page.
My current setup goes:
I grabbed what was in the /example/solr folder when I download Solr and unzipped this into a new folder called solr located here:
/var/lib/tomcat6/webapps/solr/WEB-INF
I installed right here since a tutorial had me skip the step for placing the solr.xml file here to point to another location, like /opt/solr/ or whatnot:
So to further clarify, my file structure in here goes.
/solr/
|--/bin/
|--/collection1/
|--/drupalsolr/ (this is my core/instace)
|--/conf/
|--solr.xml
|--zoo.cfg
/solr.war
/weblogic.xml (was in here originally)
When I visit :8080 and then click to the Tomcat Manager, I see /solr is 'running'. Yet when I click /solr on here. It gives me a 404 error.
HTTP Status 404 - /solr/
type Status report
message /solr/
description The requested resource (/solr/) is not available.
Apache Tomcat/6.0.24
Where do I begin with fixing this? Is there any sort of errors I can find besides a 404 not found error?
Ok, I am following this tutorial with how they used a Context Path file and have the Solr installation outside the Tomcat folder. I moved it to /opt/solr instead and edited the generated context path web.xml file that is located here: /var/lib/tomcat6/webapps/solr/WEB-INF/web.xml
Here is what I edited in the web.xml file now:
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/opt/solr</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
I now get the error 'FAIL: Application at context path /solr could not be started'. So I guess this means my actual Solr core isn't set up properly. I googled around and it might be my .jar files. It's hard to tell without a proper error.
I also made sure my $JAVA_HOME is set to /urs/local/jdk
Here are the errors form the log:

The default solr port is 8983 or is set in solr configuration and then as noted here the URL structure is
http://localhost:8983/solr/{{solrCoreName}}
If this does not work it may be worth checking that solr service actually runs (for ubuntu / debian -> service solr 8983 status or similar for your distro or by checking process list).
