The following steps are required to install Apache Tomcat under Ubuntu 10.10:
- install Sun Java JRE/SDK
For guidelines see for instance http://www.mkyong.com/java/how-to-install-java-jdk-on-ubuntu-linux/.
- set PATH, CLASSPATH and JAVA_HOME (Ubuntu should set it automatically when installing Java:
export PATH=$PATH:/usr/lib/jvm/java-6-sun/bin export JAVA_HOME="/usr/lib/jvm/java-6-sun" export CLASSPATH="/usr/lib/jvm/java-6-sun"
Hint: In case you want to make this changes permanent and system-wide you could edit /etc/environment accordingly.
- download and unpack Apache Tomcat to for instance /opt/tomcat/
- start Apache Tomcat using:
Tomcat should start with the following settings:
Using CATALINA_BASE: /opt/tomcat Using CATALINA_HOME: /opt/tomcat Using CATALINA_TMPDIR: /opt/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar
- sometimes it is useful to change CATALINA_HOME to your local (NetBeans, Eclipse, etc.) workspace:
- activate Tomcat’s manager by creating a manager-user in tomcat-users.xml:
<?xml version='1.0' encoding='utf-8'?> <tomcat-users> <role rolename="manager"/> <user username="admin" password="secret" roles="admin,manager"/> </tomcat-users>
Hint: When deploying using for instance NetBeans be sure that the current user has enough rights for the corresponding Tomcat working directory, e.g. /opt/tomcat/work/. This can be achieved with chown or chmod from within the shell.
