以centos为例

1. 创建一个tomcat文件，内容如下

   #!/bin/bash
   #
   # Startup script for the tomcat
   # chkconfig: 2345 90 60
   
   # source function library
   . /etc/rc.d/init.d/functions
   # 这里的tomcat地址修改成你的tomcat地址
   tomcat=/apache-tomcat-7.0.77
   startup=$tomcat/bin/startup.sh
   shutdown=$tomcat/bin/shutdown.sh
   
   start() {
     echo -n $"Starting Tomcat service: "
     sh $startup
     echo $?
   }
   
   stop() {
     echo -n $"Stopping Tomcat service: "
     sh $shutdown
     echo $?
   }
   
   restart() {
     stop
     start
   }
   
   status() {
     ps -aef | grep apache-tomcat | grep -v grep
   }
   
   # Handle the different input options
   case "$1" in
   start)
     start
     ;;
   stop)
     stop
     ;;
   status)
     status
     ;;
   restart)
     restart
     ;;
   *)
     echo $"Usage: $0 {start|stop|restart|status}"
     exit 1
   esac
   
   exit 0

2. 将tomcat文件复制到/etc/init.d目录下

3. 授权

   cd /etc/init.d
   chmod u+x tomcat

4. 设置tomcat为一个服务

   chkconfig --add tomcat

5. 设置tomcat自启动

   chkconfig tomcat on

6. 尝试如下命令吧

   service tomcat start
   service tomcat status
   service tomcat restart
   service tomcat stop
