01-初识InfluxDB
1. InfluxDB介绍
时间序列数据库，简称时序数据库，Time Series Database，一个全新的领域，最大的特点就是每个条数据都带有Time列。
时序数据库到底能用到什么业务场景，答案是：监控系统。
InfluxDB是一个当下比较流行的时序数据库，InfluxDB使用 Go 语言编写，无需外部依赖，安装配置非常方便，适合构建大型分布式系统的监控系统。

路径 /etc/influxdb/influxdb.conf
1 ### Welcome to the InfluxDB configuration file.
2
3 # The values in this file override the default values used by the system if
4 # a config option is not specified. The commented out lines are the configuration
5 # field and the default value used. Uncommenting a line and changing the value
6 # will change the value used at runtime when the process is restarted.
7
8 # Once every 24 hours InfluxDB will report usage data to usage.influxdata.com
9 # The data includes a random ID, os, arch, version, the number of series and other
10 # usage data. No data from user databases is ever transmitted.
11 # Change this option to true to disable reporting.
12 # 该选项用于上报influxdb的使用信息给InfluxData公司，默认值为false
13 # reporting-disabled = false

1 Usage of influx: 2 -version 3 Display the version and exit. 4 -host 'host name' 5 Host to connect to. 6 -port 'port #' 7 Port to connect to. 8 -socket 'unix domain socket' 9 Unix socket to connect to. 10 -database 'database name' 11 Database to connect to the server. 12 -password 'password' 13 Password to connect to the server. Leaving blank will prompt for password (--password ''). 14 -username 'username' 15 Username to connect to the server. 16 -ssl 17 Use https for requests. 18 -unsafeSsl 19 Set this when connecting to the cluster using https and not use SSL verification. 20 -execute 'command' 21 Execute command and quit. 22 -type 'influxql|flux' 23 Type specifies the query language for executing commands or when invoking the REPL. 24 -format 'json|csv|column' 25 Format specifies the format of the server responses: json, csv, or column. 26 -precision 'rfc3339|h|m|s|ms|u|ns' 27 Precision specifies the format of the timestamp: rfc3339, h, m, s, ms, u or ns. 28 -consistency 'any|one|quorum|all' 29 Set write consistency level: any, one, quorum, or all 30 -pretty 31 Turns on pretty print for the json format. 32 -import 33 Import a previous database export from file 34 -pps 35 How many points per second the import will allow. By default it is zero and will not throttle importing. 36 -path 37 Path to file to import 38 -compressed 39 Set to true if the import file is compressed
