简介
Elasticsearch
Elasticsearch是一个实时的分布式搜索分析引擎， 它能让你以一个之前从未有过的速度和规模，去探索你的数据。它被用作全文检索、结构化搜索、分析以及这三个功能的组合。支持集群配置。
Logstash/Filebeats
Logstash是一款强大的数据处理工具，它可以实现数据传输，格式处理，格式化输出，还有强大的插件功能，常用于日志处理。。
Kibana
kibana是一个开源和免费的工具，它可以为Logstash和ElasticSearch提供的日志分析友好的Web界面，可以帮助您汇总、分析和搜索重要数据日志。

brew info your-software
# 管理服务，没怎么用它，ELK都有自己的启动脚本在安装目录的bin/下面，且基本上都会携带参数启动
brew services start/stop your-service

#mac安装elasticsearch
brew install elasticsearch
elasticsearch的相关安装位置
安装目录：/usr/local/Cellar/elasticsearch/{elasticsearch-version}/
日志目录：/usr/local/var/log/elasticsearch/
插件目录：/usr/local/var/elasticsearch/plugins/
配置目录：/usr/local/etc/elasticsearch/
启动
brew services start elasticsearch
首次启动，默认的端口号是9200，用户名是elastic，密码我也不知道（资料上查到的都是6.0以前的版本，密码是changeme，6.0以后不清楚），通过调用_xpack接口修改默认密码：
版本
elasticsearch --version
Version: 6.6.1, Build: oss/tar/1fd8f69/2019-02-13T17:10:04.160291Z, JVM: 1.8.0_131
Kibana
mac安装kibana
brew install kibana
安装位置
安装目录：/usr/local/Cellar/kibana/{kibana-version}/
配置目录：/usr/local/etc/kibana/
备注
启动kibana之前，需要先修改一下配置文件/usr/local/etc/kibana/kibana.yml，取消elasticsearch.name和elasticsearch.password的注释，并将值改为上面修改过的用户名密码username: elastic, password: 123456，请参考下面的kibana.yml片段
# kibana.yml
# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana
# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
# is proxied through the Kibana server.
elasticsearch.username: "elastic"
elasticsearch.password: "changeme"
启动
brew services start kibana
首次启动，默认端口号是5601，打开浏览器访问http://localhost:5601访问kibana管理页面，会弹框要求输入用户名密码，输入elastic和123456即可。
注：这里的kibana.yml中配置的用户名密码是kibana访问elasticsearch需要用到的，而web页面手动输入的用户名密码是我们登录kibana管理页面的密码，它们为什么能共用一个密码，不太清楚。
版本
kibana --version
6.6.1
Logstash
mac安装logstash
brew install logstash
logstash的相关安装位置
安装目录：/usr/local/Cellar/logstash/{logstash-version}/
配置目录：/usr/local/etc/logstash
配置
vim ./first-pipeline.conf
- 支持Filebeat作为输入源
# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.
input {
beats {
host =>"127.0.0.1"
port => "5044"
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
#user => "elastic"
#password => "changeme"
}
}
- logstash 配置文件输入支持文件输入，例如：
[root@access-1 logstash-7.2.1]# cat logstash_809.conf
input {
file{
path => ['/opt/access-server-1.0.5/log/akka-gb809.log'] #读取日志文件路径
type => "akka-gb809" #一个标签
stat_interval => "2" #每隔几秒读取日志文件，默认为1秒
}
file{
path => ['/opt/access-server-1.0.5/log/akka-gb808.log']
type => "akka-gb808"
stat_interval => "2"
}
file{
path => ['/opt/access-server-1.0.5/log/akka.log']
type => "akka"
stat_interval => "2"
}
file{
path => ['/opt/access-server-1.0.5/log/all_error.log']
type => "all_error"
stat_interval => "2"
codec => multiline { #将换行的日志打印出来
pattern => "(^d{2}:d{2}:d{2}.d{3})UTC" #匹配的正则
negate => true
what => "previous"
}
}
}
filter {
date {
match => [ "timestamp" , "yyyy-MM-dd HH:mm:ss.SSS" ]
}
}
output {
if [type] == "akka-gb809" { #要匹配的日志文件标签
elasticsearch {
hosts => "192.168.108.151:9200" #es节点地址
index => "access-1-akka-gb809" #生成的索引，用于kibana展示
}
}
if [type] == "akka-gb808" {
elasticsearch {
hosts => "192.168.108.151:9200"
index => "access-1-akka-gb808"
}
}
if [type] == "akka" {
elasticsearch {
hosts => "192.168.108.151:9200"
index => "access-1-akka"
}
}
if [type] == "all_error" {
elasticsearch {
hosts => "192.168.108.151:9200"
index => "access-1-all_error"
}
}
}
启动
logstash -e 'input { stdin { } } output { stdout {} }'
或
logstash -f config/first-pipeline.conf --config.test_and_exit
此条命令检验配置文件是否正确
logstash -f config/first-pipeline.conf --config.reload.automatic
此条命令是启动logstash，并且在first-pipeline.conf文件变更时自动重启。
后台启动
nohup logstash -f config/first-pipeline.conf --config.reload.automatic & > /dev/null
版本
logstash 6.6.1

安装
#mac安装Filebeats'
brew install filebeat
位置
安装目录：/usr/local/Cellar/filebeat/{filebeat-version}/
配置目录：/usr/local/etc/filebeat/
缓存目录：/usr/local/var/lib/filebeat/
配置
vim /usr/local/etc/filebeat//filebeat.yml
###################### Filebeat Configuration Example #########################
# This file is an example configuration file highlighting only the most common
# options. The filebeat.reference.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html
# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
- type: log
# Change to true to enable this prospector configuration.
enabled: true
# Paths that should be crawled and fetched. Glob based paths.
paths:
- /apps/intelligent-family-console/intelligentFamilyConsole/*.log
#- c:programdataelasticsearchlogs*
# Exclude lines. A list of regular expressions to match. It drops the lines that are
# matching any regular expression from the list.
#exclude_lines: ['^DBG']
# Include lines. A list of regular expressions to match. It exports the lines that are
# matching any regular expression from the list.
#include_lines: ['^ERR', '^WARN']
# Exclude files. A list of regular expressions to match. Filebeat drops the files that
# are matching any regular expression from the list. By default, no files are dropped.
#exclude_files: ['.gz$']
# Optional additional fields. These fields can be freely picked
# to add additional information to the crawled log files for filtering
#fields:
# level: debug
# review: 1
### Multiline options
# Mutiline can be used for log messages spanning multiple lines. This is common
# for Java Stack Traces or C-Line Continuation
# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#multiline.pattern: ^[
# Defines if the pattern set under pattern should be negated or not. Default is false.
#multiline.negate: false
# Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
# that was (not) matched before or after or as long as a pattern is not matched based on negate.
# Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
#multiline.match: after
#============================= Filebeat modules ===============================
filebeat.config.modules:
# Glob pattern for configuration loading
path: ${path.config}/modules.d/*.yml
# Set to true to enable config reloading
reload.enabled: false
# Period on which files under path should be checked for changes
#reload.period: 10s
#==================== Elasticsearch template setting ==========================
setup.template.settings:
index.number_of_shards: 3
#index.codec: best_compression
#_source.enabled: false
#================================ General =====================================
# The name of the shipper that publishes the network data. It can be used to group
# all the transactions sent by a single shipper in the web interface.
#name:
# The tags of the shipper are included in their own field with each
# transaction published.
#tags: ["service-X", "web-tier"]
# Optional fields that you can specify to add additional information to the
# output.
#fields:
# env: staging
#============================== Dashboards =====================================
# These settings control loading the sample dashboards to the Kibana index. Loading
# the dashboards is disabled by default and can be enabled either by setting the
# options here, or by using the `-setup` CLI flag or the `setup` command.
#setup.dashboards.enabled: false
# The URL from where to download the dashboards archive. By default this URL
# has a value which is computed based on the Beat name and version. For released
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.
#setup.dashboards.url:
#============================== Kibana =====================================
# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:
# Kibana Host
# Scheme and port can be left out and will be set to the default (http and 5601)
# In case you specify and additional path, the scheme is required: http://localhost:5601/path
# IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
#host: "localhost:5601"
#============================= Elastic Cloud ==================================
# These settings simplify using filebeat with the Elastic Cloud (https://cloud.elastic.co/).
# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:
# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.
#cloud.auth:
#================================ Outputs =====================================
# Configure what output to use when sending the data collected by the beat.
#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:
# Array of hosts to connect to.
#hosts: ["localhost:9200"]
# Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
# The Logstash hosts
hosts: ["localhost:5044"]
# Optional SSL. By default is off.
# List of root certificates for HTTPS server verifications
#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]
# Certificate for SSL client authentication
#ssl.certificate: "/etc/pki/client/cert.pem"
# Client Certificate Key
#ssl.key: "/etc/pki/client/cert.key"
#================================ Logging =====================================
# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
logging.level: debug
# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publish", "service".
#logging.selectors: ["*"]
#============================== Xpack Monitoring ===============================
# filebeat can export internal metrics to a central Elasticsearch monitoring
# cluster. This requires xpack monitoring to be enabled in Elasticsearch. The
# reporting is disabled by default.
# Set to true to enable the monitoring reporter.
#xpack.monitoring.enabled: false
# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well. Any setting that is not set is
# automatically inherited from the Elasticsearch output configuration, so if you
# have the Elasticsearch output configured, you can simply uncomment the
# following line.
#xpack.monitoring.elasticsearch:
主要是配置filebeat.inputs，采集哪些日志；关闭output.elasticsearch，打开output.logstash，将收集到的信息推送到logstash。
