Ubuntu 12.10下安裝icescrum需要首先安裝tomcat7還有jdk，直接在ubuntu下面安裝
apt-get install tomcat7
然後需要配置一下tomcat裡面的環境變量，指定icescrum的配置文件路徑，在文件/usr/share/tomcat7/bin/catalina.sh中開頭添加一個設置：
JAVA_OPTS="-Djava.awt.headless=true -XX:MaxPermSize=1024m -Xmx1024m -Dicescrum_config_location=/opt/config.groovy"
最後的一個參數就是設置icescrum的配置文件路徑。
當然該文件權限要設置一下，允許icescrum訪問。
下載R5#5.1 版本的war包，復制到/var/lib/tomcat7/webapps目錄後，tomcat7會自動解開war包。然後觀察日志/var/lib/tomcat7/logs/icescrum.log文件：

解決方法是到/usr/share/tomcat7目錄下創建icescrum目錄，然後設置權限：
chown tomcat7:tomcat7 -R ./icescrum/
