用的版本仍旧是tomcat6.0
原有的为：tomcat6.0，新增加的为tomcat6.0-2
1 在/etc/profile中添加以下粗体的配置
#原有的tocmat配置
TOMCAT_HOME=/usr/local/tomcat6.0
CATALINA_HOME=/usr/local/tomcat6.0
CATALINA_BASE=/usr/local/tomcat6.0
export TOMCAT_HOME CATALINA_HOME CATALINA_BASE
#添加的tocmat配置，可照此样添加多个tomcat
TOMCAT_2_HOME=/usr/local/tomcat6.0-2
CATALINA_2_HOME=/usr/local/tomcat6.0-2
CATALINA_2_BASE=/usr/local/tomcat6.0-2
export TOMCAT_2_HOME CATALINA_2_HOME CATALINA_2_BASE
2 修改tomcat6.0-2的bin/shutdown.sh，在exec "$PRGDIR"/"$EXECUTABLE" stop "$@"这行前边添加如下配置：
export JAVA_HOME=/usr/local/jdk1.6
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=$JAVA_HOME/lib
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
3 修改tomcat6.0.-2的bin/startup.sh，在exec "$PRGDIR"/"$EXECUTABLE" stop "$@"这行前边添加如下配置：
export JAVA_HOME=/usr/local/jdk1.6
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=$JAVA_HOME/lib
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
4 修改tocmat6.0-2的conf/server.xml，更改端口
-----------------------------tocmat6.0-2的server.xml配置如下----------------

配置两个两个以上都是如此，不过在优化装apr时，没有成功，具体原因还木有空去找 = = 有空再说吧
对多个tomcat优化apr时己经成功了，写在那个优化贴子里
