INSTALLAZIONE TOMCAT COMPLETATA
Se si vuole accedere agli appplicativi che girano su tomcat senza dover digitare il numero di porta (8080) allora è necessario configurare il jk connectors o il proxy_ajp.

Per il connector jk seguire i seguenti semplici passi:
1.Scaricare il connector da http://tomcat.apache.org/download-connectors.cgi (Binary Release và bene)
2.Rinominare il file scaricato in mod_jk.so e copiarlo nella cartella modules di apache
3.Creare il file jk_connectors.con in /etc/httpd/conf.d:
LoadModule jk_module modules/mod_jk.so
# Configuration for mod_jk.so.
JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile     /var/log/httpd/mod_jk.log
JkShmFile     /var/log/httpd/jk-runtime-status
JkLogLevel    info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /app/* ajp13
JkMount /app2/* ajp13
4.Creare il file workers.properties in /etc/httpd/conf:
workers.tomcat_home=/usr/share/tomcat6/
workers.java_home=/usr/java/jdk
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.default.lbfactor=1
5.Avviare apache.
