不废话，直接上干货,本配置试用于InfluxDB version 1.6
vim /etc/influxdb/influxdb.conf
### Welcome to the InfluxDB configuration file.
# The values in this file override the default values used by the system if
# a config option is not specified. The commented out lines are the configuration
# field and the default value used. Uncommenting a line and changing the value
# will change the value used at runtime when the process is restarted.
# Once every 24 hours InfluxDB will report usage data to usage.influxdata.com
# The data includes a random ID, os, arch, version, the number of series and other
# usage data. No data from user databases is ever transmitted.
# Change this option to true to disable reporting.
# reporting-disabled = false
# Bind address to use for the RPC service for backup and restore.

# max-concurrent-compactions = 0
# The threshold, in bytes, when an index write-ahead log file will compact
