Linux监听FTP

监听FTP是否开启

1.编写如下脚本，判断字符串是否包含时根据实际情况

不需要多次判断的去掉循环

#!/bin/bash
var1="/usr/sbin/vsftpd"
count=4
seconds=2
echo $(date '+%Y-%m-%d %H:%M:%S')" Test Start"
for i in $(seq $count)
do
	ftps=$(ps -ef | grep /usr/sbin/vsftpd|awk '{print $8}')
	echo "$ftps" | grep -q "$var1"
	if [ $? -eq 0 ]
	then
		echo $(date '+%Y-%m-%d %H:%M:%S')" Test success"
		break;
	else
		echo $(date '+%Y-%m-%d %H:%M:%S')" Test failed "$i
		if [ $i -eq $count ]
		then
			echo $(/sbin/service vsftpd restart)
		else
			sleep $[$i*$seconds]s		
		fi
	fi
done
echo $(date '+%Y-%m-%d %H:%M:%S')" Test End"
echo ""

2.crontab -e添加定时任务
