这篇文章主要向大家介绍ElasticStack的入门学习,主要内容包括基础应用、实用技巧、原理机制等方面,希望对大家有所帮助。

Beats,Logstash负责数据收集与处理。至关于ETL(Extract Transform Load)。
Elasticsearch负责数据存储、查询、分析。
Kibana负责数据探索与可视化分析。

一、Elasticsearch 6.x版本的安装,我这里使用Elasticsearch 6.7.0版本的。java

备注:以前安装过5.4.3版本的,https://www.cnblogs.com/biehongli/p/11643482.htmlnode

二、将下载好的安装包上传到服务器上面,或者你在线下载也能够的哦。mysql

注意:记得先安装好jdk1.8版本及其以上的哦。因为以前安装出现了错误,有了一点经验,这里先建立用户和所属组。linux

 1 [root@slaver4 package]# groupadd elsearch
 2 [root@slaver4 package]# useradd elsearch -g elsearch 
 3 [root@slaver4 package]# passwd elsearch
 4 更改用户 elsearch 的密码 。
 5 新的 密码:
 6 无效的密码: 密码少于 8 个字符
 7 从新输入新的 密码:
 8 passwd:全部的身份验证令牌已经成功更新。
 9 [root@slaver4 package]# tar -zxvf elasticsearch-6.7.0.tar.gz -C /home/hadoop/soft/
10 [root@slaver4 soft]# chown -R elsearch:elsearch elasticsearch-6.7.0/
11 [root@slaver4 soft]# ls

此次竟然很顺利,可是在浏览器使用http://192.168.110.133:9200/访问是不行的,这里修改一下配置文件,使用浏览器也能够进行访问。nginx

在配置文件elasticsearch.yml中添加以下所示配置:sql

network.host: 192.168.110.133express

1 [elsearch@slaver4 soft]$ cd elasticsearch-6.7.0/
2 [elsearch@slaver4 elasticsearch-6.7.0]$ ls
3 bin  config  data  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
4 [elsearch@slaver4 elasticsearch-6.7.0]$ cd config/

6 elasticsearch.keystore  elasticsearch.yml  jvm.options  log4j2.properties  role_mapping.yml  roles.yml  users  users_roles
7 [elsearch@slaver4 config]$ vim elasticsearch.yml

好吧,这个配置文件一修改就报错了,错误和第一次基本一致,这里也贴一下吧。apache

55 [elsearch@slaver4 bin]$

错误1、[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535],解决方法以下所示:

错误缘由,每一个进程最大同时打开文件数过小,可经过下面2个命令查看当前数量。

注意,切记,若是按照此方法修改,必须重启你的虚拟机,并且是root用户修改的配置文件,否则你解决完报的这两个错误,再次启动elasticsearch仍是会报错误一,可是不会报错误二,因此重启虚拟机之后解决这两个错误。

1 [root@slaver4 ~]# vim /etc/security/limits.conf

添加以下所示内容:

注意:解释如是,*是表明任何用户,此配置的意思是任何用户均可以打开文件的数量。

1 *               soft    nofile          65536
2 *               hard    nofile          65536

操做以下所示:

错误2、[2]: max number of threads [3756] for user [elsearch] is too low, increase to at least [4096]

错误缘由,最大线程个数过低。修改配置文件/etc/security/limits.conf(和问题1是一个文件),增长配置。

*               soft    nproc           4096
*               hard    nproc           4096

错误3、[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

错误缘由,应该是虚拟内存不足致使的错误。修改/etc/sysctl.conf文件,增长配置vm.max_map_count=262144。执行命令sysctl -p生效。

1 [root@slaver4 ~]# vim /etc/sysctl.conf
2 [root@slaver4 ~]# sysctl -p
3 vm.max_map_count = 262144 4 [root@slaver4 ~]# 

添加内容以下所示:

1 vm.max_map_count=262144

操做以下所示:

解决完上述两个错误之后,最好停机虚拟机,再次启动便可,使用浏览器访问也出现了正常,以下所示:

使用curl  192.168.110.133:9200能够看到访问成功了。也说明你的ElasticSearch启动成功了。

三、elasticsearch.yml的关键配置说明。

cluster.name是集群的名称,以此做为是否同一集群的判断条件。
node.name节点名称,以此做为集群中不一样节点的区分条件。
network.host/http.port是网络地址和端口,用于http和tranport服务使用。
path.data是数据存储地址。
path.log是日志存储地址。

elasticsearch两种模式,一种是开发者模式,一种是生产模式。
Development与Production模式说明。
以transport的地址是否绑定在localhost为判断标准network.host。若是不是localhost或者127.0.0.1都认为是生产模式。
Development模式下在启动时候会以warning的方式提示配置检查异常。
Production模式下在启动时候会以error的方式提示配置检查异常并退出。

参数修改的第二种方式:bin/elasticsearch -Ehttp.port=19200

 四、Elasticsearch集群的搭建:https://www.cnblogs.com/biehongli/p/11650045.html

elasticsearch本地快速启动集群的方式,自行练习便可:
bin/elasticsearch
bin/elasticsearch -Ehttp.port=8200 -Epath.data=node2
bin/elasticsearch -Ehttp.port=7200 -Epath.data=node3


http://192.168.110.133:9200/_cat/nodes能够查看集群是否组成集群。
http://192.168.110.133:9200/_cluster/stats能够查看集群的状态。

 五、Kibane的安装与运行。

Kibane的安装下载,解压缩操做以下所示:

 1 [root@slaver4 package]# ls
 2 elasticsearch-6.7.0.tar.gz
 3 [root@slaver4 package]# wget https://artifacts.elastic.co/downloads/kibana/kibana-6.7.0-linux-x86_64.tar.gz
 4 --2019-10-25 16:12:36--  https://artifacts.elastic.co/downloads/kibana/kibana-6.7.0-linux-x86_64.tar.gz
 5 正在解析主机 artifacts.elastic.co (artifacts.elastic.co)... 151.101.110.222, 2a04:4e42:1a::734
 6 正在链接 artifacts.elastic.co (artifacts.elastic.co)|151.101.110.222|:443... 已链接。
 7 已发出 HTTP 请求,正在等待回应... 200 OK

 9 正在保存至: “kibana-6.7.0-linux-x86_64.tar.gz”
10 
11 100%[======================================================================================================================================================================================>] 186,406,262 5.31MB/s 用时 40s    
12 
13 2019-10-25 16:13:17 (4.41 MB/s) - 已保存 “kibana-6.7.0-linux-x86_64.tar.gz” [186406262/186406262])
14 
15 [root@slaver4 package]# ls
16 elasticsearch-6.7.0.tar.gz  kibana-6.7.0-linux-x86_64.tar.gz
17 [root@slaver4 package]# tar -zxvf kibana-6.7.0-linux-x86_64.tar.gz -C /home/hadoop/soft/

解压缩完毕,修改配置文件,我将kibana的目录赋给本身建立的用户及其用户组,以下所示:

server.port: 5601           # 默认是5601,不改也能够。
server.host: "192.168.110.133" # 修改此参数,能够在浏览器访问的。
elasticsearch.hosts: ["http://192.168.110.133:9200"]

修改完毕,能够启动kibana,更多参数修改你能够本身尝试。当出现Server running at http://localhost:5601就已经启动成功了。

操做以下所示:

七、Beats入门学习。Lightweight Data Shipper,轻量级的数据传送者。

Filebeat日志文件。
  处理流程:输入Input、处理Filter、输出Output。 Metricbeat度量数据。
  主要用来搜集cpu数据,内存数据,磁盘数据,nginx,mysql。 Packetbeat网络数据。 Winlogbeat,Windows数据。 Auditbeat Heartbeat建康检查。 Functionbeat

Filebeat的配置简介:

a、Filebeat Input配置简介,使用的是yaml语法。input_type目前有两个类型,分别是log日志文件、stdin标准输入。
    案例以下所示:
    filebeat.properties:
        -input_type:log
            paths:
                -/var/log/apache/httpd-*.log
        -input_type:log
            paths:
                -/var/log/messages
                -/var/log/*.log
                
b、Filebeat Output配置简介,支持的Output对象包含,Console标准输出、Elasticsearch、Logstash、Kafka、Redis、File。
    案例以下所示:
    output.elasticsearch:
        hosts:["http://localhost:9200"]      # elasticsearch的链接地址
        username:"admin"                    # 用户权限认证,须要配置帐号密码
        password:"123456"
            
    output.console:                         # 输出到控制台,方便调试。
        pretty:true                            # 输出作json的格式化。
        
c、Filebeat Filter配置简介。
    Input 时处理
        Include_lines : 达到某些条件的时候,读入这一行。
        exclude_lines :达到某些条件的时候,不读入这一行。
        exclude_files:当文件名符合某些条件的时候,不读取这个文件。

    output 前处理 --Processor
        drop_event :读取到某一条,知足了某个条件,不输出。
        drop_fields :读取到某一条,知足了某个条件,不输出这个字段。
        Decode_json_fields :把这条数据里面符合json格式的字段,去作json的解析。
        Include_fields :加入一些字段,或者是只想取数据里面的某一些字段。

    案例以下所示:
    processors:
        -drop_event:
            when:
                regexp: # 正则表达式,当匹配到message字段以DBG开头的进行丢弃。
                    message:"^DBG:"
                
    processors:
        -decode_json_fields: # 将结果处理成正常的json格式的。
            fields:["inner"]
                
d、Filebeat高级使用简介:        
    Filebeat + Elasticsearch Ingest Node组合使用。
        缘由:Filebeat 缺少数据转换的能力。
    Elasticsearch Ingest Node介绍以下所示:
        新增的node类型。
        在数据写入es前对数据进行处理转换。
        使用的api是pipeline api。

八、Filebeat的下载,安装部署。Filebeat是go开发的,因此分操做系统的。根据本身需求下载哦。

你能够下载好,上传到服务器,我是使用wget命令直接下载了。

 1 [root@slaver4 package]# ls
 2 elasticsearch-6.7.0.tar.gz  kibana-6.7.0-linux-x86_64.tar.gz

17 [root@slaver4 package]# tar -zxvf filebeat-6.7.0-linux-x86_64.tar.gz -C /home/hadoop/soft/

因为使用的是root进行解压缩操做的,将文件拥有者赋予给elsearch本身新建的用户和用户组。

filebeat-6.7.0-linux-x86_64的文件解释以下所示:

data存储的是filebeat解析过程当中会去存日志读到的位置。
filebeat是可执行文件。
module是filebeat支持的模块的功能。

 1 [root@slaver4 package]# cd ../soft/
 2 [root@slaver4 soft]# ls
 3 elasticsearch-6.7.0  filebeat-6.7.0-linux-x86_64  kibana-6.7.0-linux-x86_64

下面,经过一个简单案例,使用Filebeat收集nginx log日志,经过stdin收集日志。经过console输出结果。

首先修改一下filebeat的配置,修改配置如谢谢所示:

 1 #=========================== Filebeat inputs =============================
 2 
 3 filebeat.inputs:
 4 
 5 # Each - is an input. Most options can be set at the input level, so
 6 # you can use different inputs for various configurations.
 7 # Below are the input specific configurations.
 8 
 9 - type: log
10 
11   # Change to true to enable this input configuration.
12   enabled: false
13 
14   # Paths that should be crawled and fetched. Glob based paths.
15   paths:
16     # - /var/log/*.log
17     - /home/hadoop/soft/elasticsearch-6.7.0/logs
18     #- c:\programdata\elasticsearch\logs\*
19     
20     
21 
22 #-------------------------- Elasticsearch output ------------------------------
23 output.elasticsearch:
24   # Array of hosts to connect to.
25   # hosts: ["localhost:9200"]
26   hosts: ["192.168.110.133:9200"]  
27 
28   # Enabled ilm (beta) to use index lifecycle management instead daily indices.
29   #ilm.enabled: false
30 
31   # Optional protocol and basic auth credentials.
32   #protocol: "https"
33   #username: "elastic"
34   #password: "changeme"
35     
36

启动你的filebeat就能够看到日志信息。

[elsearch@slaver4 filebeat-6.7.0-linux-x86_64]$ ./filebeat -e -c filebeat.yml -d "publish"

九、Logstash入门,下载安装部署,以下所示。

  简介data shipper (不是轻量级的,会比beats占用更多的资源,可是功能强大)。

  ETL的概念:Extract 对数据进行提取、Transform 转换、Load 对外的输出。

  Logstash 是一个开源的,服务端的数据处理流,能够同时从多个数据源提取数据、转换数据、最后把数据放到你要存储的地方。

十、Logstash处理流程,以下所示:

  input:能够从file 、Redis 、beats、kafka等读取数据。

  filter :gork(表达式,简单理解为基于正则的,能够将非格式化数据转化成格式化数据的语法)、mutate(能够对结构化的数据的字段进行增删改查)、drop、date。

  output :能够向stdout 、elasticsearch 、Redis、kafka等中输出。

处理流程,Input和Output的配置,因为Logstash不是yaml语法。
    input{file{path => "/tmp/abc.log"}}
    output{stdout{codec => rubydebug}}

处理流程,Filter配置。
    Grok,基于正则表达式提供了丰富可重用的模式(pattern)。基于此能够将非结构化数据作结构化处理。
    Date,将字符串类型的时间字段转换为时间戳类型,方便后续数据处理。
    Mutate,进行增长,修改,删除,替换等字段相关的处理。

十一、Logstash的下载,安装,Logstash是Ruby开发的哦。以下所示:

Logstash也是基于JVM的应用,我这里直接下载tar包,方便操做,压缩包略大,百十兆哈。

 1 [root@slaver4 package]# wget https://artifacts.elastic.co/downloads/logstash/logstash-6.7.0.tar.gz
