Installing Solr on Ubuntu Jaunty 9.04
Posted on August 20th, 2009 13 comments
Solr install success on Ubuntu Jaunty 9.04
I just installed Apache Solr on Ubuntu Jaunty 9.04. I am not a Java or Tomcat person, so it was all rather new and a confusing, there was no good install guide and I hit a few walls, so here are some pointers that should get you to a working install.
I am using the command-line install method, so it’s works for desktop and server editions. You can skip the apt-gets and use Synaptics Package Manager to install the packages if you prefer.
1) Install Java
sudo apt-get install sun-java6-bin sun-java6-demo sun-java6-jdk sun-java6-jreI believe the default install of Jaunty installs openjdk java, so you will want to make sure that Sun Java is chosen:
sudo update-alternatives --config javaYou will prompted to pick a version as the default:
Select the Sun Java version
Edit /etc/profile to sent the JAVA_HOME environment variable:
JAVA_HOME=/usr/lib/jvm/java-6-sun
export JAVA_HOME2) Install Tomcat
sudo apt-get install tomcat5.5 libtomcat5.5-java tomcat5.5-admin tomcat5.5-webappsCheck that Tomcat is running:
sudo service tomcat5.5 statusGrant yourself Tomcat Manager and Admin permissions; edit /usr/share/tomcat5.5/conf/tomcat-users.xml and include the following:
<user username="myname" password="mypassword" roles="admin,manager"/>3 Install Solr
sudo apt-get install solr-common solr-tomcat5.5 libxpp3-java(I kept getting “java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException at java.lang.Class.forName0(Native Method)” in the Solr admin page; a little searching led me to find that the problems was that libxpp3-java was not installed. Why it’s not a required package, I don’t know!)
4) Restart Tomcat and Test Solr
sudo service tomcat5.5 restartNow you can go to the Tomcat web admin page at http://localhost:8180/ and login with the credentials you supplied above.
Go to http://localhost:8180/solr/ and do a test query to confirm it’s working.
Of course you will get zero results, you have no content indexed yet.
That should be enough to get started!

Nice – I’ll add a link to these instructions from the ApacheSolr Drupal documentation. Are you going to demo Drupal and Solr at BarCamp?
-
I still have a lot of learning to do on Solr. Maybe I have enough time to figure it out to show it off at the next Barcamp-unless we have another DrupalCamp and I show it off there.
-
Hi! Thanks a lot! That was not so easy to find, as solr-tomcat5.5 has had other problems.
-
Awesome! I had the same error relating to libxpp3-java. Thanks for figuring that out and posting it. Works perfectly now.
-
Glad somebody else is finding it useful! Thanks for the feedback.

Just a note for you. If you set the JAVA_HOME by creating a file in /etc/profile.d/ then it woun’t get trashed by some ubuntu update in the future:
echo “export JAVA_HOME=/usr/lib/jvm/java-6-sun”>/etc/profile.d/java-home.sh
-
We’re trying out Solr in conjunction with Django + Haystack. This tutorial really helped me (I dislike the Java/Tomcat world).
-
Thank for your kindness! It is awesome!!
-
thank for sharing but I wanna update that solr version to the newest. Do you know how?
-
for solr on Debian without tomcat. How could i configure solr to start automatically on restart? anyone know?
-
Thank for sharing your experience, It has saved much time for me.

Seems better to place env. variables in /etc/environment
