如何在系统重启时自动重启Tomcat7？

我已经在运行于Amzon EC2实例的Ubuntu 12.04 LTS上安装了Tomcat 7。现在，我希望tomcat应该在系统重新启动时自动重新启动。

我读了这个博客，建议在下面添加以下脚本/etc/init.d/tomcat7：

# Tomcat auto-start
#
# description: Auto-starts tomcat
# processname: tomcat
# pidfile: /var/run/tomcat.pid

case $1 in
start)
sh /usr/share/tomcat7/bin/startup.sh
;;
stop) 
sh /usr/share/tomcat7/bin/shutdown.sh
;;
restart)
sh /usr/share/tomcat7/bin/shutdown.sh
sh /usr/share/tomcat7/bin/startup.sh
;;
esac 
exit 0

并发出以下命令：

sudo chmod 755 /etc/init.d/tomcat7

sudo ln -s /etc/init.d/tomcat7 /etc/rc1.d/K99tomcat

sudo ln -s /etc/init.d/tomcat7 /etc/rc2.d/S99tomcat

sudo /etc/init.d/tomcat7 restart

我的问题

1. 该tomcat7已经在它的脚本，在这里我们必须粘贴提示脚本？
2. 建议的程序是否正确？

在/etc/init.d/tomcat7中创建初始化脚本，其内容如下所示（您的脚本也应该工作，但我认为该脚本更符合标准）。

这样，Tomcat仅在配置了网络接口后才能启动。

初始化脚本内容：

#!/bin/bash

### BEGIN INIT INFO
# Provides:        tomcat7
# Required-Start:  $network
# Required-Stop:   $network
# Default-Start:   2 3 4 5
# Default-Stop:    0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO

PATH=/sbin:/bin:/usr/sbin:/usr/bin

start() {
 sh /usr/share/tomcat7/bin/startup.sh
}

stop() {
 sh /usr/share/tomcat7/bin/shutdown.sh
}

case $1 in
  start|stop) $1;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac

更改其权限并自动添加正确的符号链接：

chmod 755 /etc/init.d/tomcat7
update-rc.d tomcat7 defaults

从现在开始，它将在输入适当的运行级别时自动启动和关闭。您也可以使用service tomcat7 <stop|start|restart>

#!/bin/bash
#
# Author : subz
# Copyright (c) 2k15
#
# Make kill the tomcat process
#
TOMCAT_HOME=/media/subin/works/Applications/apache-tomcat-7.0.57
SHUTDOWN_WAIT=5

tomcat_pid() {
  echo `ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'`
}

start() {
  pid=$(tomcat_pid)
  if [ -n "$pid" ] 
  then
    echo "Tomcat is already running (pid: $pid)"
  else
    # Start tomcat
    echo "Starting tomcat"
    /bin/sh $TOMCAT_HOME/bin/startup.sh
  fi


  return 0
}

stop() {
  pid=$(tomcat_pid)
  if [ -n "$pid" ]
  then
    echo "Stoping Tomcat"
    /bin/sh $TOMCAT_HOME/bin/shutdown.sh

    let kwait=$SHUTDOWN_WAIT
    count=0;
    until [ `ps -p $pid | grep -c $pid` = '0' ] || [ $count -gt $kwait ]
    do
      echo -n -e "\nwaiting for processes to exit";
      sleep 1
      let count=$count+1;
    done

    if [ $count -gt $kwait ]; then
      echo -n -e "\nkilling processes which didn't stop after $SHUTDOWN_WAIT seconds"
      kill -9 $pid
      echo  " \nprocess killed manually"
    fi
  else
    echo "Tomcat is not running"
  fi

  return 0
}
pid=$(tomcat_pid)

 if [ -n "$pid" ]
  then
    echo "Tomcat is running with pid: $pid"
    stop
  else
    echo "Tomcat is not running"
    start
  fi
exit 0

不能将此添加到 /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

sleep 10
/usr/share/tomcat7/bin/startup.sh

Digital Ocean提供了有关使用Tomcat 8.x和Ubuntu 16.04 LTS和systemd脚本的非常方便的指南。

apache tomcat不附带任何初始化脚本。

1. 从Ubuntu软件包管理器安装由Ubuntu维护的预打包版本，该版本附带了自己的初始化脚本。

2. 请按照您所引用的博客中为您提供kickstart初始化脚本的步骤进行操作。
