How-To install Tomcat 7 and Solr on Centos 5.5

In this how-to we are presenting the steps you have to follow in order to install Tomcat 7 and Solr on a Centos 5.5 machine.

Install Java JDK

yum install java-(version)-openjdk
yum install java-(version)-openjdk-devel

where (version) must be a valid version of the JDK.

Install Tomcat 7

cd /usr/shared/
wget http://apache.cc.uoc.gr/tomcat/tomcat-7/v7.0.22/bin/apache-tomcat-7.0.22.tar.gz
tar -zxvf apache-tomcat-7.0.22.tar.gz
rm apache-tomcat-7.0.22.tar.gz

You can find the version to download from the binary distribution HERE.

Next you must install tomcat native by downloading the source from here:

cd ~
mkdir installers && cd installers
wget http://apache.cc.uoc.gr//tomcat/tomcat-connectors/native/1.1.22/source/tomcat-native-1.1.22-src.tar.gz
tar -zxvf tomcat-native-1.1.22-src.tar.gz
rm tomcat-native-1.1.22-src.tar.gz
cd tomcat-native-1.1.22-src/jni/native
./configure --with-apr=/usr/bin/apr-1-config --with-java-home=****

**** must be the directory where the java jdk is e.g. /usr/lib/jvm/java-1.6.0-openjdk.x86_64.

make
make install

Next open up the catalina.sh (where it is probably located at /usr/share/apache-tomcat-7.0.22/bin/catalina.sh) and put export LD_LIBRARY_PATH="/usr/local/apr/lib" at the start of the file.
Finally change Tomcat default listening port by editing the /usr/share/apache-tomcat-7.0.22/conf/server.xml
and changing <Connector port="8989" to 8983 which is Solr's default port.

Install Solr

First download Solr by visiting HERE and choosing the closest mirror and finding solr. An example path is (note that Solr is in 3.1.0 version right now, please adjust version to fit your needs) http://apache.forthnet.gr//lucene/solr/3.1.0/apache-solr-3.1.0.tgz.

cd ~/installers
wget http://apache.forthnet.gr//lucene/solr/3.1.0/apache-solr-3.1.0.tgz
tar xzvf apache-solr-3.1.0.tgz
mv apache-solr-3.1.0/example/solr /opt/solr
mv apache-solr-3.1.0/dist/apache-solr-3.1.0.war /opt/solr/
cp apache-solr-3.1.0/client/ruby/solr-ruby/solr/conf/schema.xml /opt/solr/conf/

Next edit the /opt/solr/conf/solrconfig.xml and change the dataDir to ${solr.data.dir:/opt/solr/data}.
Next we are creating the solr.xml for Tomcat

cd /usr/share/apache-tomcat-7.0.22/conf/
mkdir Catalina
mkdir Catalina/solr
mkdir Catalina/solr/localhost
vim sorl.xml

and add the following to this file:

<?xml version="1.0" encoding="utf-8"?>
<Context docBase="/opt/solr/apache-solr-3.1.0.war" debug="0" crossContext="true">
  <Environment name="solr/home" type="java.lang.String" value="/opt/solr" override="true"/>
</Context>

Finally we want to make tomcat a service and make it boot on startup. For this we create an init.d script say /etc/init.d/tomcat and put the following script inside

#!/bin/bash
# description: Tomcat Start Stop Restart
# processname: tomcat
# chkconfig: 234 20 80
JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CATALINA_HOME=/usr/share/apache-tomcat-7.0.22

case $1 in
start)
sh $CATALINA_HOME/bin/startup.sh
;;
stop)
sh $CATALINA_HOME/bin/shutdown.sh
;;
restart)
sh $CATALINA_HOME/bin/shutdown.sh
sh $CATALINA_HOME/bin/startup.sh
;;
esac
exit 0

*Note* Edit the file if necessary and change JAVA_HOME and CATALINA_HOME. Now we make the service by /sbin/chkconfig tomcat on to start on boot and start the service by

/etc/init.d/tomcat start

or by

service tomcat start

One more TIP! If your queries contain unicode characters. Make sure you ‘ve set to the connector at conf/server.xml this:

<Connector port="8090" URIEncoding="UTF-8"/>

Now if you visit http://127.0.0.1:8983 you should see Tomcat’s index page and in http://127.0.0.1:8983/solr Solr’s index page (given no firewall blocking this port).
