!! 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}}}
