  7 # notice: 
  8 #        1.如果tomcat实例是在同一个目录下，那么只需要修改此脚本中 "export CATALINA_BASE=(path)/$instance_name" 
  9 #          中的path为你所有实例的父目录即可,--instance= 选项就可以使用相对路径
 10 #       2.如果tomcat实例不在同一个目录下，那么只需要修改此脚本中 "export CATALINA_BASE=$instance_name"
 11 #          --instance= 选项后面就得跟实例的绝对路径
 12 #       3.把此脚本放到/usr/local/bin/ 并重名命为tomcat-multi,注意修改其他用户有执行权限
