再扔个:tomcat多站点配置+MYSQL JDBC+非ROOT启动
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="你的网站目录" debug="0"
reloadable="true" crossC/>
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="localhost_log." suffix=".txt"
timestamp="true"/>
</Host>

--------------------------------------------------------
mysql jdbc
下载 mysql jdbc驱动后解包
cp mysql-connector-java-3.1.13-bin.jar /usr/local/tomcat/common/lib

重启TOMCAT生效
其它的驱动也是一样,我没试了,大家有兴趣可以试试
