部署INFLUDB

提供者：MappleZF

版本：1.0.0

一、部署INFLUXDB

1 .1下载并解压

wget -c https://dl.influxdata.com/influxdb/releases/influxdb-1.8.3_linux_amd64.tar.gz
tar -xf influxdb-1.8.3_linux_amd64.tar.gz -C /opt/

1.2 修改配置文件

1.2.1修改influxdb.conf

[[email protected]:/opt/influxdb/etc/influxdb]# vim 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.
# 绑定地址以用于RPC服务以进行备份和还原，默认配置是127.0.0.1:8088
# bind-address = "127.0.0.1:8088"

### 控制存储有关InfluxDB群集的元数据的Raft共识组的参数
### [meta]
###
### Controls the parameters for the Raft consensus group that stores metadata
### about the InfluxDB cluster.
###

[meta]
  # Where the metadata/raft database is stored
  # 存储元数据/ raft数据库的目录，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
  #  为元服务打印日志消息，默认值：true
  # logging-enabled = true

### 控制InfluxDB的实际分片数据的生存位置以及它从WAL中刷新的方式。 “dir”可能需要更改为适合您系统的位置，但WAL设置是高级配置。 默认值应适用于大多数系统。
### [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 = "/mnt/cephfs/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.
  # 写入在fsyncing之前等待的时间.持续时间大于0可用于批量处理多个fsync调用.这对于较慢的磁盘或看到WAL写入争用时很有用.每次写入WAL时值为0s fsyncs.对于非SSD磁盘,建议使用0-100ms范围内的值
  # 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.

  # The maximum number of concurrent full and level compactions that can run at one time.  A
  # value of 0 results in 50% of runtime.GOMAXPROCS(0) used at runtime.  Any number greater
  # than 0 limits compactions to that value.  This setting does not apply
  # to cache snapshotting.
  # 可以一次运行的最大并发完全和级别压缩数。 值为0会导致运行时使用50％运行时.GOMAXPROCS（0）。 任何大于0的数字都会限制对该值的压缩。 此设置不适用于缓存快照，默认值：0
  # max-concurrent-compactions = 0

  # CompactThroughput is the rate limit in bytes per second that we
  # will allow TSM compactions to write to disk. Note that short bursts are allowed
  # to happen at a possibly larger value, set by CompactThroughputBurst

  max-values-per-tag = 1000000

  # 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.
  # 索引预写日志文件压缩到索引文件中时的阈值（以字节为单位）。 较小的大小将导致日志文件更快地压缩，并导致较低的堆使用量，但代价是写入吞吐量。
  # 更高的大小将更少压缩，在内存中存储更多系列，并提供更高的写入吞吐量。有效大小的后缀为k，m或g（不区分大小写，1024 = 1k）。没有大小后缀的值以字节为单位，默认值：1m
  # 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.
  series-id-set-cache-size = 100

  # These next lines control how batching works. You should have this enabled
  # otherwise you could get dropped metrics or poor performance. Only points
  # metrics received over the telnet protocol undergo batching.
  
  # Flush if this many points get buffered
  # 这些下一行控制批处理的工作方式。 您应该已启用此功能，否则您可能会丢失指标或性能不佳。

  # precision = ""

  # These next lines control how batching works. You should have this enabled
  # otherwise you could get dropped metrics or poor performance. Batching
  # will buffer points in memory if you have many coming in.

  # Flush if this many points get buffered
  # 接下来的行控制批处理的工作原理。 您应该已启用此功能，否则您可能会丢失指标或性能不佳。

  # interval for how often continuous queries will be checked if they need to run
  # 检查连续查询是否需要运行的时间间隔，默认值：“1s”
  # run-interval = "1s"

### InfluxDB中TLS的全局配置设置
### [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.
  # 确定可用的密码套件集。 有关可用密码的列表，请参阅https://golang.org/pkg/crypto/tls/#pkg-constants，这取决于Go的版本（使用查询SHOW DIAGNOSTICS查看用于构建InfluxDB的Go版本）。
  # 如果未指定，则使用Go的crypto / tls包中的默认设置，默认值：ciphers =[“TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305”,“TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256”,]
  # 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.
  # 将协商的tls协议的最低版本。 如果未指定，则使用Go的crypto / tls包中的默认设置，默认值：“tls1.2”
  # 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.
  # 将协商的tls协议的最大版本。 如果未指定，则使用Go的crypto / tls包中的默认设置，默认值：“tls1.2”
  # max-version = "tls1.3"

1.3 创建Data目录

mkdir -p /mnt/cephfs/influxdb/data

1.4 添加环境变量

vim /etc/profile
export PATH=/opt/influxdb/usr/bin:$PATH
source /etc/profile

1.5设置启动文件

cp -p /opt/influxdb/usr/lib/influxdb/scripts/influxdb.service /usr/lib/systemd/system/

systemctl enable influxdb.service
systemctl start influxdb.service
systemctl status influxdb.service

netstat -ntlp | grep 8086
ps -ef | grep influxdb

1.6 基本命令

登录命令   influx
显示所有数据库   show databases
使用数据库       use 
显示该数据库中所有的表   show measurements
查询语句 -- 查询10条数据  select * from  limit 10;
select * from  where .... limit 10;
删库drop database  
删表 drop measurement 

precision rfc3339; -- 之后再查询，时间就是rfc3339标准格式
-- 或可以在连接数据库的时候，直接带该参数
influx -precision rfc3339

-- 查看一个measurement中所有的tag key 
show tag keys
-- 查看一个measurement中所有的field key 
show field keys
-- 查看一个measurement中所有的保存策略(可以有多个，一个标识为default)
show retention policies;

二、部署telegraf

2.1 下载并解压

wget -c https://dl.influxdata.com/telegraf/releases/telegraf-1.15.3_linux_amd64.tar.gz
tar -xf telegraf-1.15.3_linux_amd64.tar.gz -C /opt/
mv telegraf-1.15.3 telegraf

2.2 修改配置文件

[[email protected]:/opt/telegraf/etc/telegraf]# vim telegraf.conf
###############################################################################
#                            OUTPUT PLUGINS                                   #
###############################################################################


# Configuration for sending metrics to InfluxDB
[[outputs.influxdb]]
  ## The full HTTP or UDP URL for your InfluxDB instance.
  ##
  ## Multiple URLs can be specified for a single cluster, only ONE of the
  ## urls will be written to each interval.
  # urls = ["unix:///var/run/influxdb.sock"]
  # urls = ["udp://127.0.0.1:8089"]
  ## influxdb http地址，由于是宿主机直接安装，直接访问本地8086端口即可。
  urls = ["http://192.168.13.101:8086"]

  ## The target database for metrics; will be created as needed.
  ## For UDP url endpoint database needs to be configured on server side.
  # 数据库名，不存在会自动创建，默认"telegraf"
  database = "telegraf"

  ## The value of this tag will be used to determine the database.  If this
  ## tag is not set the 'database' option is used as the default.
  # database_tag = ""

  ## If true, the 'database_tag' will not be included in the written metric.
  # exclude_database_tag = false

  ## If true, no CREATE DATABASE queries will be sent.  Set to true when using
  ## Telegraf with a user without permissions to create databases or when the
  ## database already exists.
  # 跳过创建数据库
  skip_database_creation = false

  ## Name of existing retention policy to write to.  Empty string writes to
  ## the default retention policy.  Only takes effect when using HTTP.
  # retention_policy = ""

  ## The value of this tag will be used to determine the retention policy.  If this
  ## tag is not set the 'retention_policy' option is used as the default.
  # retention_policy_tag = ""

  ## If true, the 'retention_policy_tag' will not be included in the written metric.
  # exclude_retention_policy_tag = false
  ## Write consistency (clusters only), can be: "any", "one", "quorum", "all".
  ## Only takes effect when using HTTP.
  # write_consistency = "any"

  ## Timeout for HTTP messages.
  # 超时时间
  timeout = "5s"

  ## HTTP Basic Auth
  # username = "telegraf"
  # password = "metricsmetricsmetricsmetrics"

2.3 添加环境变量

vim /etc/profile
export PATH=/opt/telegraf/usr/bin:$PATH
source /etc/profile

2.4 设置启动文件

[[email protected]:/opt/telegraf/usr/lib/telegraf/scripts]# vim telegraf.service

:x 保存退出


cp -p /opt/telegraf/usr/lib/telegraf/scripts/telegraf.service  /usr/lib/systemd/system/

systemctl enable telegraf
systemctl start telegraf
systemctl status telegraf

三、配置Grafana

注：此处我们使用lb的集群外的grafana来配置，不使用k8s集群内的grafana

3.1 添加数据源

点击添加数据源，按照下图配置选择influxdb添加一个influxdb数据源；InfluxDB Details需填写数据名（默认telegraf）；填写完成后，点击Save&Test按钮，若访问正常，会出现Data source is working提示，否则请检查配置内容以及网络。

四、部署chronograf

4.1 下载并解压

wget https://dl.influxdata.com/chronograf/releases/chronograf-1.8.7_linux_amd64.tar.gz
tar -xf chronograf-1.8.7_linux_amd64.tar.gz -C /opt
mv chronograf-1.8.7-1 chronograf

4.2 添加环境变量

vim /etc/profile
