检查 httpd 是否打开或关闭的脚本

#!/bin/bash    
service=service_name  
email=user@domain.com     
host=`hostname -f`  
if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 0 ))  
then  
echo "$service is running"  
else  
/etc/init.d/$service start  
if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 0 ))  
then  
subject="$service at $host has been started"  
echo "$service at $host wasn't running and has been started" | mail -s   "$subject" $email  
else  
subject="$service at $host is not running"  
echo "$service at $host is stopped and cannot be started!!!" | mail -s   "$subject" $email  
fi  
fi  

如何让这个脚本在后台运行，以便它不断检查 httpd 服务是否打开或关闭，并在关闭时通过电子邮件发送消息! (PS-:我不想将脚本制作为 CRONJOB)就像在后台运行的守护进程一样! 请帮忙

如果您使用 nohup 启动脚本，它将作为守护进程运行。

nohup script.sh &
