Tomcat#

Setting up an administrative user#

File: conf/tomcat-users.xml

<tomcat-users>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="admin" password="xxxxx" roles="admin,manager"/>
</tomcat-users>

Applications#

Applications are stored under the webapps directory.


Tomcat on an Apple Mac#

Make sure you have Java 6 selected through Applications / Utils / Java Preferences

Add the following to bin/startup.sh

export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

Fixing a bad time zone#

File: bin/startup.sh

export TZ='US/Eastern'

Arahant specific parameters#

File: bin/startup.sh

export CATALINA_OPTS="-Xms256M -Xmx1424M -XX:MaxPermSize=256M"

You can also add the following to that line to monitor the Java GC:

-Xloggc:/home/arahant/tomcat/logs/gc.log

You can also add the following line to the same file in order to clear out old log files:

rm -f ../logs/*

On Windows servers:

Environment variables don't work. Use the Tomcat config utility (Start / Programs / ...). Define min & max memory in the text box. Define -XX parameter in the listbox.


To make shared libraries work#

File: conf/catalina.properties

shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar

Changing the default webapp#

This allows the user to type in the URL without having to add /webapp to the end.

cd webapps/ROOT mv index.html manage.html

Create an index.html page in that directory with the following:

<html>
<head>
<meta http-equiv="refresh" content="0;URL=http:myapp/">
</head>
<body>
</body>
</html>

Make sure to change "myapp" in the above XML.

You can still access tomcat manager with http://mydomain/manage.html

If you also switch to https you must use the whole URL. You can, however, auto-forward to the HTTP address and then have tomcat switch to HTTPS.


Auto-starting Tomcat on Linux servers#

Add the following line to /etc/rc.local to auto-start tomcat before the line with "exit 0".

/home/arahant/tomcat/bin/startup.sh

Making Tomcat forget about old apps#

rm -rf tomcat/conf/Catalina/localhost

Fixing the big where it can't create a GUID for localhost#

ifconfig
uname -n

Put that name and IP address in /etc/hosts
