Ubuntu12.10 icescrum 设置

安装icescrum需要首先安装tomcat7还有jdk，直接在ubuntu下面安装

apt-get install tomcat7

然后需要配置一下tomcat里面的环境变量，指定icescrum的配置文件路径，在文件/usr/share/tomcat7/bin/catalina.sh中开头添加一个设置：

JAVA_OPTS="-Djava.awt.headless=true -XX:MaxPermSize=1024m -Xmx1024m -Dicescrum_config_location=/opt/config.groovy"

最后的一个参数就是设置icescrum的配置文件路径。


当然该文件权限要设置一下，允许icescrum访问。

下载R5#5.1 版本的war包，复制到/var/lib/tomcat7/webapps目录后，tomcat7会自动解开war包。然后观察日志/var/lib/tomcat7/logs/icescrum.log文件：

解决方法是到/usr/share/tomcat7目录下创建icescrum目录，然后设置权限：

chown tomcat7:tomcat7 -R ./icescrum/

再次重新启动tomcat7,观察日志,错误变成了：

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

到这里下载mysql jdbc driver，见鬼，IceScrum产品也也太牛了，难道不能将依赖自动带进来么？
将jar包复制到/usr/share/tomcat7/lib目录下。
删除不需要的hsqldb 的jar包。

root@scrum:/var/lib/tomcat7/webapps/icescrum/WEB-INF/lib# rm hsqldb-1.8.0.10.jar

现在看一下关键的/opt/config.groovy文件内容：

// Data Source
dataSource.driverClassName = "com.mysql.jdbc.Driver"
dataSource.dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
dataSource.url = "jdbc:mysql://10.112.18.182:3306/icescrum?useUnicode=true&characterEncoding=utf8&autoReconnect=true"
dataSource.username = "scrum"
dataSource.password = "youpwd"

// Use pool connection
dataSource.pooled=true
dataSource.properties.maxActive=50
dataSource.properties.maxIdle=25
dataSource.properties.minIdle=1
dataSource.properties.initialSize=1
dataSource.properties.minEvictableIdleTimeMillis=1800000
dataSource.properties.timeBetweenEvictionRunsMillis=1800000
dataSource.properties.numTestsPerEvictionRun=3
dataSource.properties.maxWait=10000
dataSource.properties.testOnBorrow=true
dataSource.properties.testWhileIdle=true
dataSource.properties.testOnReturn=false
dataSource.properties.validationQuery="SELECT 1"

icescrum部署的确比较麻烦，建议不要依赖什么tomcat，自己做一个standalone server的解决方案。

顺便说一下tomcat7的几个目录：
/usr/share/tomcat7/下面是tomcat7的程序，一些环境变量配置也在这个目录下。
/var/lib/tomcat7目录是tomcat7的用户目录，应用程序和日志都在这个下面。
