 # notice:
 #        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)/$instance_name"
 #          中的path为你所有实例的父目录即可,--instance= 选项就可以使用相对路径
 #       2.如果tomcat实例不在同一个目录下，那么只需要修改此脚本中 "export CATALINA_BASE=$instance_name"
 #          --instance= 选项后面就得跟实例的绝对路径
 #       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 

 # 定义java的相关变量
 export JAVA_HOME=/usr/java/latest

实例操作：

　1.查看一个实例的状态

2.查看帮助信息，没有使用-h选项，不过你可以故意给错选项来查看 ，提供了比较简单地几个选项。

3.多实例操作，需要以下的脚本，你可以把它保存并重名命为tomcatd，然后把它扔到/etc/init.d/tomcatd ,确保其有执行权限。

 #!/bin/bash
 #
 # chkconfig:
 # description: tomcat multi instance init scripts

 # 通过instance数组把你要启动的tomcat实例写在这里
 instance=("tomcat8001" "tomcat8002")

 # 该服务需要用到的执行程序
 prog=/usr/local/bin/tomcat-multi

 # 通过for循环遍历数组内的实例名称启动多个实例
 case $ in
 start)
     for i in ${instance[*]};do $prog  --instance=$i start;done
     ;;

 stop)
     for i in ${instance[*]};do $prog  --instance=$i stop;done
     ;;

 restart)
     for i in ${instance[*]};do $prog  --instance=$i restart;done
     ;;

 configtest)
     for i in ${instance[*]};do $prog  --instance=$i configtest;done
     ;;

 status)
     for i in ${instance[*]};do $prog  --instance=$i status;done
     ;;
                                                                        

  4. 启动并打印日志

　

总结：

     @解决tomcat多实例在部署应用程序后每个手动重启。

     @通过status 选项查看tomcat实例在线情况

     @实现tomcat多实例集中管理，当然通过tomcat-multi 可以实现单实例管理

     @脚本有不合适地方，还请大家给予指出，这里只是给大家一个模板
