Obtain and extract the WAR file:
wget http://www.atlassian.com/software/jira/downloads/binary/atlassian-jira-enterprise-3.10.2.tar.gz
gunzip atlassian-jira-enterprise-3.10.2.tar.gz
gtar -xf atlassian-jira-enterprise-3.10.2.tar.gz
Tomcat is installed through Blastwave. The path is /opt/csw/share/tomcat5. Follow the Tomcat installation instructions. The transaction factory in the WAR's edit-webapp/WEB-INF/classes/entitymanager.xml is set to Tomcat and does not need to be changed. There are only two settings to be changed for use with PostgreSQL. Build the distribution and copy from dist-tomcat/ to the web server.
Copy and edit the jira.xml file:
cp {WAR}/dist-tomcat/tomcat5.5/jira.xml /opt/csw/share/tomcat5/conf/Catalina/localhost
The resource should now have four lines:
username="jira_user"
password="{password}"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql:jiradb"
Obtain the JDBC driver for Tomcat and move it to common/lib:
wget http://jdbc.postgresql.org/download/postgresql-8.1-410.jdbc3.jar
Extract the jars to Tomcat's common/lib/ directory:
wget http://www.atlassian.com/software/jira/docs/servers/jars/v1/jira-jars-tomcat5.zip
Start Tomcat and go do the setup wizard. LDAP authentication is not tightly coupled therefore you must create JIRA users with the same name as the LDAP users for this to work. A bulk-import of LDAP users can be done if desired.
