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 bug where it can't create a GUID for localhost#
ifconfig uname -n
Put that name and IP address in /etc/hosts
