通过redis自带的info命令来监控redis的健康状态，通过redis-cli PING命令来监控redis的存活状态。
附件中有监控模板，将监控脚本放在redis服务器的自定义的/scripts/zabbix_redis/下:

zabbix参数key的设置：
# cat /etc/zabbix/zabbix_agentd.d/userparameter_redis.conf UserParameter=Redis.Status, redis-cli PING|grep -c "PONG" UserParameter=Redis.Info[*], /bin/sh /scripts/zabbix_redis/zabbix_redis.sh $1
模板见附件.其中对脚本传入两个参数的部分，对于不同的环境可能会不太兼容，可以对模板和脚本进行修改，或者直接在模板中禁用对应的item。
