#tomcat 定时重启步骤：
#1. 编写linux 脚本文件（已给，需要改变jdk，tomcat路径）
#2. 添加定时任务：
#   >  crontab -e
#   >  */1 * * * * /xxx/restart-tomcat.sh
#	   ||
#	   || ==》 每分钟执行一次	   
#	   建议每周六凌晨2点执行一次 ==》 0 2 * * 6    
#   保存
#   > :wq
#   查看crontab服务状态
#   > service crond status/start/stop/reload/restart
#   加入开机启动
#   chkconfig --level 345 crond on
#   查看开机启动是否成功
#   chkconfig --list | grep 'crond'
