01-初识InfluxDB

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。

2. 安装方法

2.1 linux版本

软件包：influxdb-1.7.7.x86_64.rpm

安装命令：yum localinstall influxdb-1.7.7.x86_64.rpm

2.2 常用命令

/usr/bin/influxd influxdb服务器

/usr/bin/influx influxdb命令行客户端

/usr/bin/influx_inspect 查看工具

/usr/bin/influx_stress 压力测试工具

/usr/bin/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）

2.3 常用目录

/var/lib/influxdb/data 存放最终存储的数据，文件以.tsm结尾

/var/lib/influxdb/meta 存放数据库元数据

/var/lib/influxdb/wal 存放预写日志文件

2.4 配置文件

路径 /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.
 # 该选项用于上报influxdb的使用信息给InfluxData公司，默认值为false
 # reporting-disabled = false

 # Bind address to use for the RPC service for backup and restore.
 # 备份恢复时使用，默认值为8088
 # bind-address = "127.0.0.1:8088"

 ###
 ### [meta]
 ###
 ### Controls the parameters for the Raft consensus group that stores metadata
 ### about the InfluxDB cluster.
 ###

 [meta]
   # Where the metadata/raft database is stored
   # meta数据存放目录，默认值：/var/lib/influxdb/meta
   dir = "/var/lib/influxdb/meta"

   # Automatically create a default retention policy when creating a database.
   # 用于控制默认存储策略，数据库创建时，会自动生成autogen的存储策略，默认值：true
   # retention-autocreate = true

   # If log messages are printed for the meta service
   # 是否开启日志，默认值：true
   # logging-enabled = true

 ###
 ### [data]
 ###
 ### Controls where the actual shard data for InfluxDB lives and how it is
 ### flushed from the WAL. "dir" may need to be changed to a suitable place
 ### for your system, but the WAL settings are an advanced configuration. The
 ### defaults should work for most systems.
 ###

 [data]
   # The directory where the TSM storage engine stores TSM files.
   # 最终数据（TSM文件）存储目录，默认值：/var/lib/influxdb/data
   dir = "/var/lib/influxdb/data"

   # 预写日志存储目录，默认值：/var/lib/influxdb/wal
   wal-dir = "/var/lib/influxdb/wal"

   # The amount of time that a write will wait before fsyncing.  A duration
   # greater than 0 can be used to batch up multiple fsync calls.  This is useful for slower
   # disks or when WAL write contention is seen.  A value of 0s fsyncs every write to the WAL.
   # Values in the range of 0-100ms are recommended for non-SSD disks.
   # wal-fsync-delay = "0s"

   # The type of shard index to use for new shards.  The default is an in-memory index that is
   # recreated at startup.  A value of "tsi1" will use a disk based index that supports higher
   # cardinality datasets.
   # index-version = "inmem"

   # snapshot the cache and write it to a TSM file, freeing up memory
   # Valid size suffixes are k, m, or g (case insensitive, 1024 = 1k).
   # Values without a size suffix are in bytes.
   # 用于设置快照大小，大于该值时数据会刷新到tsm文件，默认值：
   # DefaultCacheSnapshotMemorySize = 25 * 1024 * 1024 // 25MB
   # cache-snapshot-memory-size = "25m"

   # CacheSnapshotWriteColdDuration is the length of time at

   # will allow TSM compactions to write to disk.
   # compact-throughput-burst = "48m"

   # If true, then the mmap advise value MADV_WILLNEED will be provided to the kernel with respect to
   # TSM files. This setting has been found to be problematic on some kernels, and defaults to off.
   # It might help users who have slow disks in some cases.
   # tsm-use-madv-willneed = false

   # Settings for the inmem index

   # The maximum series allowed per database before writes are dropped.  This limit can prevent

   # max-values-per-tag = 100000

   # Settings for the tsi1 index

   # The threshold, in bytes, when an index write-ahead log file will compact
   # into an index file. Lower sizes will cause log files to be compacted more
   # quickly and result in lower heap usage at the expense of write throughput.
   # Higher sizes will be compacted less frequently, store more series in-memory,
   # and provide higher write throughput.
   # Valid size suffixes are k, m, or g (case insensitive, 1024 = 1k).
   # Values without a size suffix are in bytes.
   # max-index-log-file-size = "1m"

   # The size of the internal cache used in the TSI index to store previously
   # calculated series results. Cached results will be returned quickly from the cache rather
   # than needing to be recalculated when a subsequent query with a matching tag key/value
   # predicate is executed. Setting this value to 0 will disable the cache, which may
   # lead to query performance issues.
   # This value should only be increased if it is known that the set of regularly used
   # tag key/value predicates across all measurements for a database is larger than 100. An
   # increase in cache size may lead to an increase in heap usage.

范例：

# 连接本机的IfluxDB
influx

# 连接指定主机的InfluxDB
influx -host localhost

# 连接指定主机指定端口的InfluxDB
influx -host localhost -port 8086

# 连接指定主机指定端口的InfluxDB的指定数据库
influx -host localhost -port 8086 -database testdb

# 使用指定用户连接指定主机指定端口的InfluxDB的指定数据库
influx -host localhost -port 8086 -database testdb -username root

# 使用指定用户密码连接指定主机指定端口的InfluxDB的指定数据库
influx -host localhost -port 8086 -database testdb -username root -password root

# 远程执行命令
influx -execute 'show databases;'

# 使用指定用户密码连接指定主机指定端口的InfluxDB的指定数据库执行命令，返回结果为json格式
influx -host localhost -port 8086 -database testdb -username root -password root -execute 'select * from win' -format 'json'

# 使用指定用户密码连接指定主机指定端口的InfluxDB的指定数据库执行命令，返回结果为json格式，并进行格式优化
