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。html

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，http://www.javashuo.com/article/p-ojobhgzk-bk.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

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/

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

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：http://www.javashuo.com/article/p-rplnnwlu-e.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

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。

kibana访问界面以下所示：

Kibana配置说明，配置位于config文件夹中。kibana.yml关键配置说明。

server.host/server.port 访问kibana的地址和端口号。 elasticsearh.host（以前是elasticsearh.url）待访问elasticsearh的地址。

Kibana经常使用功能说明。
　　Discover数据搜索查看。Visualize图标制做。Dashboard仪表盘制做。Timelion时序数据的高级可视化分析。DevTools开发者工具。Management配置。

六、Elasticsearch与Kibana入门。Elasticsearch术语介绍与CRUD实际操做。

Elasticsearch经常使用术语。 Document文档数据。 Index索引。 Type索引中的数据类型。6.x版本以及之后版本慢慢废除此说法。 Field字段，文档的属性。 Query DESL查询语法。

Create建立文档。Read读取文档。Update更新文档。Delete删除文档。

 1 GET _search  2 {  3   "query": {  4     "match_all": {}  5  }  6 }  7 
 8 # 插入  9 PUT /account/person/1
10 { 11   "name": "zhangsan", 12   "age": 22
13 } 14 
15 PUT /account/person/2
16 { 17   "name": "zhangsan", 18   "age": 22
19 } 20 
21 # 查询 22 GET /account/person/2
23 
24 # 修改 25 POST /account/person/1/_update 26 { 27   "doc":{ 28     "name": "lisi", 29     "age": 25
30  } 31 } 32 
33 # 删除 34 DELETE /account/person/1
35 
36 DELETE /account 37 
38  
39 
40 GET /account/_mapping 41 
42 
43 # Query String 44 GET /account/person/_search?q=zhangsan 45 
46 # Query DSL 47 GET /account/person/_search 48 { 49     "query":{ 50         "match":{ 51             "name": "lisi"
52  } 53  } 54 }

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。

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。

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  4 [root@slaver4 soft]# chown -R elsearch:elsearch filebeat-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。
