Alfredcl先说说需求。
针对于某个应用集群，集群中有3台机器，任一台上的服务端口死掉（这里拿zabbix服务作为示例）都要立即电话告警出来.
这里用到的电话告警媒介是国内的喵提醒。
#!/bin/sh
IP="10.161.11.x 10.161.11.xx 10.161.11.xxx"
LOCK_FILE="/root/lockfile.txt"
rm -f /root/zabbix_status.txt
for target in $IP
do
nmap -p 10050 $target|grep open|awk '{print $2}' >> zabbix_status.txt
done
if [ `cat zabbix_status.txt|grep open|wc -l` == 3 ]; then
echo "All zabbix_agent are ok!"
rm -f $LOCK_FILE
else
if [ -f "$LOCK_FILE" ]; then
echo "zabbix is still down,won't make call again"
exit 0
else
curl http://miaotixing.com/trigger?id=xxxxxxx
touch $LOCK_FILE
fi
fi
