As follow up post to setting up solr i show you how to integrate tomcat into Apache as main web server:

The setup was made under ubuntu 11.10 with the following prerequisites:

• CATALINA_HOME is /usr/share/tomcat7
• JAVA_HOME is /usr/lib/jvm/default-java
• HOSTNAME in my case is ubuntu-vm.localdomain

1. apt-get install libapache2-mod-jk
2. nano /etc/apache2/workers.properties with the following contents

workers.tomcat_home=/usr/share/tomcat7
workers.java_home=/usr/lib/jvm/default-java
ps=/
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1

1. nano /etc/apache2/mods-available/jk.conf with the following contents

        # Where to find workers.properties
        JkWorkersFile /etc/apache2/workers.properties
        # Where to put jk shared memory
        JkShmFile     /var/log/apache2/mod_jk.shm
        # Where to put jk logs
        JkLogFile     /var/log/apache2/mod_jk.log
        # Set the jk log level [debug/error/info]
        JkLogLevel    info
        # Select the timestamp log format
        JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
        # solr redirect
        JkMount /solr* ajp13

1. less /etc/apache2/mods-available/jk.load to see the following contents
1. LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
2. run a2enmod jk to see if mod_jk is enabled
1. Module jk already enabled
3. less /usr/share/tomcat7/conf/server.xml to see a line like this
1. <Connector port=”8009″ protocol=”AJP/1.3″ redirectPort=”8443″ />
4. nano /etc/apache2/sites-available/default and insert a line into the virtualHost:80 section
1. JKMountCopy On
5. restart apache2 with service apach2 restart
6. Open a browser on your client to open http://ubuntu-vm.localdomain/solr/admin/
