1.Influxdb安裝

https://blog.csdn.net/weixin_43786255/article/details/107133899

1.1.Influxdb下載

獲取tar包

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.0_linux_amd64.tar.gz

1.2.解壓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

可執(zhí)行文件路徑為：{influxdb目錄}/usr/bin
安裝InfluxDB之后，在/usr/bin下會有如下幾個文件：

influxd influxdb服務(wù)器 influx influxdb命令行客戶端 influx_inspect 查看工具 influx_stress 壓力測試工具 influx_tsm 數(shù)據(jù)庫轉(zhuǎn)換工具（將數(shù)據(jù)庫從b1或bz1格式轉(zhuǎn)換為tsm1格式）

默認(rèn)配置文件所在路徑：{influxdb目錄}/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：

其中，修改端口的是：

1.6.啟動

cd /root/installed/influxdb/usr/bin nohup ./influxd -config /data/influxdb/conf/influxdb.conf > influxdb.log 2>&1 &

啟動日志如下：

[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 ts=2021-08-10T09:40:34.625789Z lvl=info msg="Starting precreation service" log_id=0Vsro8Hl000 service=shard-precreation check_interval=10m advance_period=30m ts=2021-08-10T09:40:34.626089Z lvl=info msg="Starting snapshot service" log_id=0Vsro8Hl000 service=snapshot ts=2021-08-10T09:40:34.627613Z lvl=info msg="Starting continuous query service" log_id=0Vsro8Hl000 service=continuous_querier ts=2021-08-10T09:40:34.626355Z lvl=info msg="Storing statistics" log_id=0Vsro8Hl000 service=monitor db_instance=_internal db_rp=monitor interval=10s ts=2021-08-10T09:40:34.627886Z lvl=info msg="Starting HTTP service" log_id=0Vsro8Hl000 service=httpd authentication=false ts=2021-08-10T09:40:34.628627Z lvl=info msg="opened HTTP access log" log_id=0Vsro8Hl000 service=httpd path=stderr ts=2021-08-10T09:40:34.628868Z lvl=info msg="Listening on HTTP" log_id=0Vsro8Hl000 service=httpd addr=[::]:8086 https=false ts=2021-08-10T09:40:34.629726Z lvl=info msg="Starting retention policy enforcement service" log_id=0Vsro8Hl000 service=retention check_interval=30m ts=2021-08-10T09:40:34.629991Z lvl=info msg="Listening for signals" log_id=0Vsro8Hl000 ts=2021-08-10T09:40:34.630847Z lvl=info msg="Sending usage statistics to usage.influxdata.com" log_id=0Vsro8Hl000

1.7.啟動influxdb控制臺，第一次啟動會較慢，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 ---- ----- tuzq true >

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是連接influxdb的一個CLI程序，在本地成功安裝influxdb后，influxdb啟動，influx命令就可以直接使用。Influxdb默認(rèn)在8086端口運(yùn)行。Influx cli默認(rèn)使用localhost：8085連接。可以使用-host和-port選項(xiàng)，連接到其他機(jī)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使用舉例

Influx命令連接數(shù)據(jù)庫后，可以使用類sql語句查詢數(shù)據(jù)

命令解釋

CREATE DATABASE database_name	建立數(shù)據(jù)庫
SHOW DATABASES	查詢所有數(shù)據(jù)庫
USE database_name	USE database_name
INSERT cpu,host=host_name,region=cn value=66	插數(shù)據(jù)入cpu measurement，標(biāo)簽host=host_name，region=cn, field是value=66
SELECT “host”, “region”, “value” FROM “cpu”	從cpu measurement查詢數(shù)據(jù)
SELECT * FROM “cpu”	從cpu measurement查詢所有數(shù)據(jù)

2.4.Influxdb的數(shù)據(jù)格式

Influxdb是一個時序數(shù)據(jù)庫，其保存metric的在某一系列時間點(diǎn)的狀態(tài)。這些點(diǎn)狀態(tài)包含時間戳，一個所謂的“measurement”名稱，至少一個稱為filed的鍵值對，以及0到多個標(biāo)簽(如 host=bigdata01)。

在influxdb中可以把measurement看為關(guān)系數(shù)據(jù)庫中的table，tag和field是其中的列。其中Tag都加了索引、field不加。和關(guān)系數(shù)據(jù)庫不同的是，不用預(yù)先定義schema，沒有value的點(diǎn)不會被保存。其格式如下：

<measurement>[,<tag-key>=<tag-value>...] <field-key>=<field-value>[,<field2-key>=<field2-value>...] [unix-nano-timestamp]

舉例：

cpu,host=bigdata01,region=cn value=66payment,device=mobile,product=Notepad,method=credit billed=88,licenses=2i 1434067469156329323

3.Influxdb客戶端工具

下載InfluxDBStudio-0.2.0，解壓，然后點(diǎn)擊：InfluxDBStudio.exe , 配置好參數(shù)配置：

示例：
