解决Linux下使用h5ss间歇性失败问题

#!/bin/bash

step=10 #10秒检查一次，间隔不能大于60

	echo "正在检测端口。。。"
	curl -s -m 3 http://192.168.1.118:8080/api/v1/GetSystemInfo

		DATE_N=`date "+%Y-%m-%d %H:%M:%S"`

# Edit this file to introduce tasks to be run by cron.
# 
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
# 
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').# 
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
# 
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
# 
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
# 
# For more information see the manual pages of crontab(5) and cron(8)
# 
# m h  dom mon dow   command
* * * * * /root/checkUrl.sh #这里是上面那个脚本的路径
