InfluxDB 报错 connection refused service=subscriber 解决思路

InfluxDB 的日志中有大量如下报错：

Post http://localhost:9092/write?consistency=&db=_internal&precision=ns&rp=monitor: dial tcp 127.0.0.1:9092: getsockopt: connection refused service=subscriber

解决思路

取消 kapacitor 订阅：

/home/s/server/influxdb/bin/influx
Connected to http://localhost:8086 version 1.2.4
InfluxDB shell version: 1.2.4
> show subscriptions
