Beats，Logstash負責數據收集與處理。至關於ETL（Extract Transform Load）。
Elasticsearch負責數據存儲、查詢、分析。
Kibana負責數據探索與可視化分析。html

一、Elasticsearch 6.x版本的安裝，我這裏使用Elasticsearch 6.7.0版本的。java

備註：以前安裝過5.4.3版本的，http://www.javashuo.com/article/p-ojobhgzk-bk.htmlnode

二、將下載好的安裝包上傳到服務器上面，或者你在線下載也能夠的哦。mysql

注意：記得先安裝好jdk1.8版本及其以上的哦。因爲以前安裝出現了錯誤，有了一點經驗，這裏先建立用戶和所屬組。linux

此次竟然很順利，可是在瀏覽器使用http://192.168.110.133:9200/訪問是不行的，這裏修改一下配置文件，使用瀏覽器也能夠進行訪問。nginx

使用命令curl http://127.0.0.1:9200/是正常的。正則表達式

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/
5 [elsearch@slaver4 config]$ ls 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，這個配置文件一修改就報錯了，錯誤和第一次基本一致，這裏也貼一下吧。apache

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

錯誤緣由，每一個進程最大同時打開文件數過小，可經過下面2個命令查看當前數量。

注意，切記，若是按照此方法修改，必須重啓你的虛擬機，並且是root用戶修改的配置文件，否則你解決完報的這兩個錯誤，再次啓動elasticsearch仍是會報錯誤一，可是不會報錯誤二，因此重啓虛擬機之後解決這兩個錯誤。

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

添加以下所示內容：

注意：解釋如是，*是表明任何用戶，此配置的意思是任何用戶均可以打開文件的數量。

1 * soft nofile 65536 2 * hard nofile 65536

操做以下所示：

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

錯誤緣由，最大線程個數過低。修改配置文件/etc/security/limits.conf（和問題1是一個文件），增長配置。

*               soft    nproc           4096
*               hard    nproc           4096

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

錯誤緣由，應該是虛擬內存不足致使的錯誤。修改/etc/sysctl.conf文件，增長配置vm.max_map_count=262144。執行命令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 ~]#

添加內容以下所示：

1 vm.max_map_count=262144

操做以下所示：

解決完上述兩個錯誤之後，最好停機虛擬機，再次啓動便可，使用瀏覽器訪問也出現了正常，以下所示：

使用curl 192.168.110.133:9200能夠看到訪問成功了。也說明你的ElasticSearch啓動成功了。

三、elasticsearch.yml的關鍵配置說明。

cluster.name是集羣的名稱，以此做爲是否同一集羣的判斷條件。 node.name節點名稱，以此做爲集羣中不一樣節點的區分條件。 network.host/http.port是網絡地址和端口，用於http和tranport服務使用。 path.data是數據存儲地址。 path.log是日誌存儲地址。

elasticsearch兩種模式，一種是開發者模式，一種是生產模式。
Development與Production模式說明。
以transport的地址是否綁定在localhost爲判斷標準network.host。若是不是localhost或者127.0.0.1都認爲是生產模式。
Development模式下在啓動時候會以warning的方式提示配置檢查異常。
Production模式下在啓動時候會以error的方式提示配置檢查異常並退出。

參數修改的第二種方式:bin/elasticsearch -Ehttp.port=19200

四、Elasticsearch集羣的搭建：http://www.javashuo.com/article/p-rplnnwlu-e.html

elasticsearch本地快速啓動集羣的方式，自行練習便可： 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能夠查看集羣是否組成集羣。
http://192.168.110.133:9200/_cluster/stats能夠查看集羣的狀態。

五、Kibane的安裝與運行。

Kibane的安裝下載，解壓縮操做以下所示：

 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 正在解析主機 artifacts.elastic.co (artifacts.elastic.co)... 151.101.110.222, 2a04:4e42:1a::734
 6 正在鏈接 artifacts.elastic.co (artifacts.elastic.co)|151.101.110.222|:443... 已鏈接。  7 已發出 HTTP 請求，正在等待迴應... 200 OK  8 長度：186406262 (178M) [application/x-gzip]  9 正在保存至: 「kibana-6.7.0-linux-x86_64.tar.gz」 10 
11 100%[======================================================================================================================================================================================>] 186,406,262 5.31MB/s 用時 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/

解壓縮完畢，修改配置文件，我將kibana的目錄賦給本身建立的用戶及其用戶組，以下所示：

server.port: 5601　　　　　　　　　　　# 默認是5601，不改也能夠。
server.host: "192.168.110.133"      # 修改此參數，能夠在瀏覽器訪問的。
elasticsearch.hosts: ["http://192.168.110.133:9200"]

修改完畢，能夠啓動kibana，更多參數修改你能夠本身嘗試。當出現Server running at http://localhost:5601就已經啓動成功了。

a、Filebeat Input配置簡介，使用的是yaml語法。input_type目前有兩個類型，分別是log日誌文件、stdin標準輸入。 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配置簡介，支持的Output對象包含，Console標準輸出、Elasticsearch、Logstash、Kafka、Redis、File。 案例以下所示： output.elasticsearch: hosts:["http://localhost:9200"] # elasticsearch的鏈接地址 username:"admin" # 用戶權限認證，須要配置帳號密碼 password:"123456" output.console: # 輸出到控制檯，方便調試。 pretty:true # 輸出作json的格式化。 c、Filebeat Filter配置簡介。 Input 時處理 Include_lines : 達到某些條件的時候，讀入這一行。 exclude_lines ：達到某些條件的時候，不讀入這一行。 exclude_files：當文件名符合某些條件的時候，不讀取這個文件。 output 前處理 --Processor drop_event ：讀取到某一條，知足了某個條件，不輸出。 drop_fields ：讀取到某一條，知足了某個條件，不輸出這個字段。 Decode_json_fields ：把這條數據裏面符合json格式的字段，去作json的解析。 Include_fields ：加入一些字段，或者是隻想取數據裏面的某一些字段。 案例以下所示: processors: -drop_event: when: regexp: # 正則表達式，當匹配到message字段以DBG開頭的進行丟棄。 message:"^DBG:" processors: -decode_json_fields: # 將結果處理成正常的json格式的。 fields:["inner"] d、Filebeat高級使用簡介： Filebeat + Elasticsearch Ingest Node組合使用。 緣由：Filebeat 缺少數據轉換的能力。 Elasticsearch Ingest Node介紹以下所示： 新增的node類型。 在數據寫入es前對數據進行處理轉換。 使用的api是pipeline api。

八、Filebeat的下載，安裝部署。Filebeat是go開發的，因此分操做系統的。根據本身需求下載哦。

你能夠下載好，上傳到服務器，我是使用wget命令直接下載了。

因爲使用的是root進行解壓縮操做的，將文件擁有者賦予給elsearch本身新建的用戶和用戶組。

filebeat-6.7.0-linux-x86_64的文件解釋以下所示：

data存儲的是filebeat解析過程當中會去存日誌讀到的位置。
filebeat是可執行文件。
module是filebeat支持的模塊的功能。

 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，經過一個簡單案例，使用Filebeat收集nginx log日誌，經過stdin收集日誌。經過console輸出結果。

首先修改一下filebeat的配置，修改配置如謝謝所示：

 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

啓動你的filebeat就能夠看到日誌信息。

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

九、Logstash入門，下載安裝部署，以下所示。

　　簡介data shipper （不是輕量級的，會比beats佔用更多的資源，可是功能強大）。

　　ETL的概念：Extract 對數據進行提取、Transform 轉換、Load 對外的輸出。

　　Logstash 是一個開源的，服務端的數據處理流，能夠同時從多個數據源提取數據、轉換數據、最後把數據放到你要存儲的地方。

十、Logstash處理流程，以下所示：

　　input：能夠從file 、Redis 、beats、kafka等讀取數據。

　　filter ：gork(表達式，簡單理解爲基於正則的，能夠將非格式化數據轉化成格式化數據的語法)、mutate（能夠對結構化的數據的字段進行增刪改查）、drop、date。

　　output ：能夠向stdout 、elasticsearch 、Redis、kafka等中輸出。

處理流程，Input和Output的配置，因爲Logstash不是yaml語法。 input{file{path => "/tmp/abc.log"}} output{stdout{codec => rubydebug}} 處理流程，Filter配置。 Grok，基於正則表達式提供了豐富可重用的模式（pattern）。基於此能夠將非結構化數據作結構化處理。 Date，將字符串類型的時間字段轉換爲時間戳類型，方便後續數據處理。 Mutate，進行增長，修改，刪除，替換等字段相關的處理。

十一、Logstash的下載，安裝，Logstash是Ruby開發的哦。以下所示：

Logstash也是基於JVM的應用，我這裏直接下載tar包，方便操做，壓縮包略大，百十兆哈。
