Beats，Logstash负责数据收集与处理。相当于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。
1、Elasticsearch 6.x版本的安装，我这里使用Elasticsearch 6.7.0版本的。
备注：之前安装过5.4.3版本的，https://www.cnblogs.com/biehongli/p/11643482.html
2、将下载好的安装包上传到服务器上面，或者你在线下载也可以的哦。
注意：记得先安装好jdk1.8版本及其以上的哦。由于之前安装出现了错误，有了一点经验，这里先创建用户和所属组。

这次居然很顺利，但是在浏览器使用http://192.168.110.133:9200/访问是不行的，这里修改一下配置文件，使用浏览器也可以进行访问。

使用命令curl http://127.0.0.1:9200/是正常的。

在配置文件elasticsearch.yml中添加如下所示配置：
network.host: 192.168.110.133

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。

错误一、[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]，解决方法如下所示：
错误原因，每个进程最大同时打开文件数太小，可通过下面2个命令查看当前数量。
注意，切记，如果按照此方法修改，必须重启你的虚拟机，而且是root用户修改的配置文件，不然你解决完报的这两个错误，再次启动elasticsearch还是会报错误一，但是不会报错误二，所以重启虚拟机以后解决这两个错误。
1 [root@slaver4 ~]# vim /etc/security/limits.conf
添加如下所示内容：
注意：解释如是，*是代表任何用户，此配置的意思是任何用户都可以打开文件的数量。
1 * soft nofile 65536
2 * hard nofile 65536
操作如下所示：
错误二、[2]: max number of threads [3756] for user [elsearch] is too low, increase to at least [4096]
错误原因，最大线程个数太低。修改配置文件/etc/security/limits.conf（和问题1是一个文件），增加配置。
* soft nproc 4096 * hard nproc 4096
错误三、[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
错误原因，应该是虚拟内存不足导致的错误。修改/etc/sysctl.conf文件，增加配置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 ~]#
添加内容如下所示：
1 vm.max_map_count=262144
操作如下所示：
解决完上述两个错误以后，最好停机虚拟机，再次启动即可，使用浏览器访问也出现了正常，如下所示：
使用curl 192.168.110.133:9200可以看到访问成功了。也说明你的ElasticSearch启动成功了。
3、elasticsearch.yml的关键配置说明。
cluster.name是集群的名称，以此作为是否同一集群的判断条件。 node.name节点名称，以此作为集群中不同节点的区分条件。 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。如果不是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
4、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，自行练习即可： 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可以查看集群是否组成集群。 http://192.168.110.133:9200/_cluster/stats可以查看集群的状态。
5、Kibane的安装与运行。
Kibane的安装下载，解压缩操作如下所示：
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 正在连接 artifacts.elastic.co (artifacts.elastic.co)|151.101.110.222|:443... 已连接。 7 已发出 HTTP 请求，正在等待回应... 200 OK 8 长度：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的目录赋给自己创建的用户及其用户组，如下所示：
server.port: 5601 # 默认是5601，不改也可以。
server.host: "192.168.110.133" # 修改此参数，可以在浏览器访问的。
elasticsearch.hosts: ["http://192.168.110.133:9200"]
修改完毕，可以启动kibana，更多参数修改你可以自己尝试。当出现Server running at http://localhost:5601就已经启动成功了。

6、Elasticsearch与Kibana入门。Elasticsearch术语介绍与CRUD实际操作。
Elasticsearch常用术语。
Document文档数据。
Index索引。
Type索引中的数据类型。6.x版本以及以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创建文档。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 }
操作如下所示：
7、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。 案例如下所示： 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。 案例如下所示： output.elasticsearch: hosts:["http://localhost:9200"] # elasticsearch的连接地址 username:"admin" # 用户权限认证，需要配置账号密码 password:"123456" output.console: # 输出到控制台，方便调试。 pretty:true # 输出做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，满足了某个条件，不输出。 drop_fields ：读取到某一条，满足了某个条件，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，去做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。 案例如下所示: 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。 原因：Filebeat 缺乏数据转换的能力。 Elasticsearch Ingest Node介绍如下所示： 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。
8、Filebeat的下载，安装部署。Filebeat是go开发的，所以分操作系统的。根据自己需求下载哦。
你可以下载好，上传到服务器，我是使用wget命令直接下载了。

由于使用的是root进行解压缩操作的，将文件拥有者赋予给elsearch自己新建的用户和用户组。
filebeat-6.7.0-linux-x86_64的文件解释如下所示：
data存储的是filebeat解析过程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/ 5 [root@slaver4 soft]# su elsearch 6 [elsearch@slaver4 soft]$ ls 7 elasticsearch-6.7.0 filebeat-6.7.0-linux-x86_64 kibana-6.7.0-linux-x86_64 8 [elsearch@slaver4 soft]$ ll 9 总用量 0 10 drwxr-xr-x. 9 elsearch elsearch 155 10月 25 15:09 elasticsearch-6.7.0 11 drwxr-xr-x. 5 elsearch elsearch 212 10月 26 10:35 filebeat-6.7.0-linux-x86_64 12 drwxr-xr-x. 13 elsearch elsearch 246 10月 25 16:13 kibana-6.7.0-linux-x86_64 13 [elsearch@slaver4 soft]$
下面，通过一个简单案例，使用Filebeat收集nginx log日志，通过stdin收集日志。通过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就可以看到日志信息。
[elsearch@slaver4 filebeat-6.7.0-linux-x86_64]$ ./filebeat -e -c filebeat.yml -d "publish"
9、Logstash入门，下载安装部署，如下所示。
简介data shipper （不是轻量级的，会比beats占用更多的资源，但是功能强大）。
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，可以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。
10、Logstash处理流程，如下所示：
input：可以从file 、Redis 、beats、kafka等读取数据。
filter ：gork(表达式，简单理解为基于正则的，可以将非格式化数据转化成格式化数据的语法)、mutate（可以对结构化的数据的字段进行增删改查）、drop、date。
output ：可以向stdout 、elasticsearch 、Redis、kafka等中输出。
处理流程，Input和Output的配置，由于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）。基于此可以将非结构化数据做结构化处理。 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，进行增加，修改，删除，替换等字段相关的处理。
11、Logstash的下载，安装，Logstash是Ruby开发的哦。如下所示：
Logstash也是基于JVM的应用，我这里直接下载tar包，方便操作，压缩包略大，百十兆哈。
