Advanced Configuration - Multiple Tomcat 5.5 Instances on Linux



Create account tomuser as in [1] with .bash_profile following bellow.

Export new environment variable CATALINA_BASE pointing for example to ~tomuser.



# su - tomuser
$pwd
/home/tomuser
$cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export CATALINA_BASE=~tomuser
export CATALINA_HOME=/home/tomcat/apache-tomcat-5.5.16
export JAVA_HOME=/home/tomcat/jdk1.5.0_06
export ANT_HOME=/home/tomcat/apache-ant-1.6.5
PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH
export PATH
export CLASSPATH=.:..:../..:$CATALINA_HOME/common/lib/servlet-api.jar:$CATALINA_HOME/common/lib/jsp-api.jar:
$CATALINA_HOME/common/lib/naming-factory-dbcp.jar
export DISPLAY=:0.0
unset USERNAME



Then:-



$cp -R $CATALINA_HOME/conf .
$cp -R $CATALINA_HOME/webapps .
$cp -R $CATALINA_HOME/shared .
$cp -R $CATALINA_HOME/work .
$cp -R $CATALINA_HOME/temp .
$cp -R $CATALINA_HOME/logs .
$cd /home/tomuser/conf/Catalina/localhost



Modify 3 files admin.xml,host-manager.xml,manager.xml.

Context should contain new value for docBase.

In particular manager.xml should look like:- 



<Context docBase="/home/tomuser/server/webapps/manager"
         privileged="true" antiResourceLocking="false" antiJARLocking="false">

  <!-- Link to the user database we will get roles from -->
  <ResourceLink name="users" global="UserDatabase"
                type="org.apache.catalina.UserDatabase"/>
</Context>



Next:-



$cp -R $CATALINA_HOME/server .
$cd conf



Modify server.xml. Three ports values should be changed:-



<Server port="8015" shutdown="SHUTDOWN">

.......

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
    <Connector port="8090" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

.......

<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8019"
               enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />



To start new TomCat instance:- 



$ $CATALINA_HOME/bin/startup.sh -Dcatalina.base=$CATALINA_BASE



Screenshot of $CATALINA_BASE/logs/catalina.out:-





Screenshot of "admin" report:-




To perform deployment with "ant" to new instance of TomCat :-



$ cd apache-tomcat-5.5.16-deployer



Make one change to build.xml,replacing old port value for TomCat by new one.



<!-- Configure properties to access the Manager application -->
  <property name="url"      value="http://localhost:8090/manager"/>
  <property name="username" value="tomcat"/>
  <property name="password" value="tomcat"/>\>
