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。
1 #!/bin/bash 2 # 3 # chkconfig: 2345 99 21 4 # description: tomcat multi instance init scripts 5 6 # 通过instance数组把你要启动的tomcat实例写在这里 7 instance=("tomcat8001" "tomcat8002") 8 9 # 该服务需要用到的执行程序 10 prog=/usr/local/bin/tomcat-multi 11 12 # 通过for循环遍历数组内的实例名称启动多个实例 13 case $1 in 14 start) 15 for i in ${instance[*]};do $prog --instance=$i start;done 16 ;; 17 18 stop) 19 for i in ${instance[*]};do $prog --instance=$i stop;done 20 ;; 21 22 restart) 23 for i in ${instance[*]};do $prog --instance=$i restart;done 24 ;; 25 26 configtest) 27 for i in ${instance[*]};do $prog --instance=$i configtest;done 28 ;; 29 30 status) 31 for i in ${instance[*]};do $prog --instance=$i status;done 32 ;; 33
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
