influxdb 导入导出数据

本文主要是介绍influxdb 导入导出数据，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

导入导出命令

# 导出，两个dir目录在influxdb.conf中有配置
influx_inspect export -datadir "/var/lib/influxdb/data" -waldir "/var/lib/influxdb/wal" -out "/data/test123456" -database lcx

# 导入 
influx -import -path=/data/lcx123

导出数据结构

导入的数据结构

前面三行我本来以为可以删除的，因为看样子是一个注释，但测试后发现不加会出错

大致看一下，第一行表示下面的语句是DML   非 DDL

第二行用来指定database，我这里用的database是 lcx

# DML
# CONTEXT-DATABASE:lcx
# CONTEXT-RETENTION-POLICY:autogen
device,identity=station-998-625 B=23 1661305890000000000
device,identity=station-998-625 B=23 1661307160000000000
device,identity=station-998-625 B=23 1661307170000000000
device,identity=station-998-625 B=23 1661307180000000000
