Shell实现判断进程是否存在并重新启动脚本

详细版：

#!/bin/bash
    #
    #调用关闭jboss进程脚本
    stopMethodServer.sh
    #打印出当前的jboss进程：grep jboss查询的jboss进程，grep -v "grep" 去掉grep进程
    jmsThread=`ps -ef | grep gdms | grep jboss | grep -v "grep"`
    echo $jmsThread
    #查询jboss进程个数：wc -l 返回行数
    count=`ps -ef | grep gdms | grep jboss | grep -v "grep" | wc -l`
    echo $count
    sec=7
    #开始一个循环，以判断进程是否关闭
    for var in 1 2
    do
     if [ $count -gt 0 ]; then
      #若进程还未关闭，则脚本sleep几秒
      echo sleep $sec second the $var time, the JMS thread is still alive
      sleep $sec
     else
      #若进程已经关闭，则跳出循环
      echo "break"
      break
     fi
    done
    #if [ $count -eq 0 ]; then
    # echo "nohup startMethodServer.sh &"
    # nohup startMethodServer.sh &
    #else
    # echo "It's better to check the thread!!!"
    #fi
    #调用启动脚本
    nohup startMethodServer.sh &

详细zabbix版本：
