目录：
- Influxdb安装 1
1.1. Influxdb下载 2
1.2. 解压tar包 2
1.3. 修改配置文件 2
1.4. 配置文件参数说明 3
1.5. 实际配置（主要是修改路径和端口） 10
1.6. 启动 33
1.7. 启动influxdb控制台，第一次启动会较慢，耐心等待 34 - 使用 34
2.1. 常用命令 34
2.2. Influx命令使用 36
2.3. Influx-sql使用举例 37
2.4. Influxdb的数据格式 37 - Influxdb客户端工具 38
1.Influxdb安装
https://blog.csdn.net/weixin_43786255/article/details/107133899
1.1.Influxdb下载
获取tar包
wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.0_linux_amd64.tar.gz
1.2.解压tar包
cd /root/software
tar -zxvf influxdb-1.8.0_linux_amd64.tar.gz -C /root/installed/cd /root/installed/
mv influxdb-1.8.0-1/ influxdb
1.3.修改配置文件
可执行文件路径为：{influxdb目录}/usr/bin
安装InfluxDB之后，在/usr/bin下会有如下几个文件：
influxd influxdb服务器
influx influxdb命令行客户端
influx_inspect 查看工具
influx_stress 压力测试工具
influx_tsm 数据库转换工具（将数据库从b1或bz1格式转换为tsm1格式）
默认配置文件所在路径：{influxdb目录}/etc/influxdb/influxdb.conf
mkdir -p /data/influxdb/conf
cp /root/installed/influxdb/etc/influxdb/influxdb.conf /data/influxdb/conf/
cd /data/influxdb
mkdir meta
mkdir data
mkdir wal
然后修改配置：

# 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

# usage data. No data from user databases is ever transmitted.

### [tls]
###
### Global configuration settings for TLS in InfluxDB.
###[tls]# Determines the available set of cipher suites. See https://golang.org/pkg/crypto/tls/#pkg-constants# for a list of available ciphers, which depends on the version of Go (use the query# SHOW DIAGNOSTICS to see the version of Go used to build InfluxDB). If not specified, uses# the default settings from Go's crypto/tls package.# ciphers = [# "TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305",# "TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305",# ]# Minimum version of the tls protocol that will be negotiated. If not specified, uses the# default settings from Go's crypto/tls package.# min-version = "tls1.2"# Maximum version of the tls protocol that will be negotiated. If not specified, uses the# default settings from Go's crypto/tls package.# max-version = "tls1.3"
其中，修改端口的是：
bind-address = "127.0.0.1:8085"
1.6.启动
cd /root/installed/influxdb/usr/bin
nohup ./influxd -config /data/influxdb/conf/influxdb.conf > influxdb.log 2>&1 &
启动日志如下：
[root@node1 bin]# pwd
/root/installed/influxdb/usr/bin
[root@node1 bin]# ls
influx influxd influxdb.log influx_inspect influx_stress influx_tsm
[root@node1 bin]# tail -f influxdb.log

1.7.启动influxdb控制台，第一次启动会较慢，耐心等待
[root@node1 bin]# ./influx -port 8085
Connected to http://localhost:8085 version 1.8.0
InfluxDB shell version: 1.8.0
> create user "tuzq" with password '123456' with all privileges
> show users
user admin
---- -----

2.使用
2.1.常用命令
[root@node1 bin]# ./influx -help
Usage of influx:-versionDisplay the version and exit.-path-prefix 'url path'Path that follows the host and port-host 'host name'Host to connect to.-port 'port #'Port to connect to.-socket 'unix domain socket'Unix socket to connect to.-database 'database name'Database to connect to the server.-password 'password'Password to connect to the server. Leaving blank will prompt for password (--password '').-username 'username'Username to connect to the server.-sslUse https for requests.-unsafeSslSet this when connecting to the cluster using https and not use SSL verification.-execute 'command'Execute command and quit.-type 'influxql|flux'Type specifies the query language for executing commands or when invoking the REPL.-format 'json|csv|column'Format specifies the format of the server responses: json, csv, or column.-precision 'rfc3339|h|m|s|ms|u|ns'Precision specifies the format of the timestamp: rfc3339, h, m, s, ms, u or ns.-consistency 'any|one|quorum|all'Set write consistency level: any, one, quorum, or all-prettyTurns on pretty print for the json format.-importImport a previous database export from file-ppsHow many points per second the import will allow. By default it is zero and will not throttle importing.-pathPath to file to import-compressedSet to true if the import file is compressedExamples:# Use influx in a non-interactive mode to query the database "metrics" and pretty print json:$ influx -database 'metrics' -execute 'select * from cpu' -format 'json' -pretty# Connect to a specific database on startup and set database context:$ influx -database 'metrics' -host 'localhost' -port '8086'
2.2.Influx命令使用
Influx是连接influxdb的一个CLI程序，在本地成功安装influxdb后，influxdb启动，influx命令就可以直接使用。Influxdb默认在8086端口运行。Influx cli默认使用localhost：8085连接。可以使用-host和-port选项，连接到其他机器或者端口。
[root@node1 bin]# ./influx -port 8085
Connected to http://localhost:8085 version 1.8.0
InfluxDB shell version: 1.8.0
>
2.3.Influx-sql使用举例
Influx命令连接数据库后，可以使用类sql语句查询数据
| 命令 | 解释 |
|---|---|
| CREATE DATABASE database_name | 建立数据库 |
| SHOW DATABASES | 查询所有数据库 |
| USE database_name | USE database_name |
| INSERT cpu,host=host_name,region=cn value=66 | 插数据入cpu measurement，标签host=host_name，region=cn, field是value=66 |
| SELECT “host”, “region”, “value” FROM “cpu” | 从cpu measurement查询数据 |
| SELECT * FROM “cpu” | 从cpu measurement查询所有数据 |
2.4.Influxdb的数据格式
Influxdb是一个时序数据库，其保存metric的在某一系列时间点的状态。这些点状态包含时间戳，一个所谓的“measurement”名称，至少一个称为filed的键值对，以及0到多个标签(如 host=bigdata01)。
在influxdb中可以把measurement看为关系数据库中的table，tag和field是其中的列。其中Tag都加了索引、field不加。和关系数据库不同的是，不用预先定义schema，没有value的点不会被保存。其格式如下：
<measurement>[,<tag-key>=<tag-value>...] <field-key>=<field-value>[,<field2-key>=<field2-value>...] [unix-nano-timestamp]
举例：
cpu,host=bigdata01,region=cn value=66payment,device=mobile,product=Notepad,method=credit billed=88,licenses=2i 1434067469156329323
3.Influxdb客户端工具
下载InfluxDBStudio-0.2.0，解压，然后点击：InfluxDBStudio.exe , 配置好参数配置：
