1、ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java语言开发的，并作为Apache许可条款下的开放源码发布，是一种流行的企业级搜索引擎。ElasticSearch用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。官方客户端在Java、.NET（C#）、PHP、Python、Apache Groovy、Ruby和许多其他语言中都是可用的。根据DB-Engines的排名显示，Elasticsearch是最受欢迎的企业搜索引擎，其次是Apache Solr，也是基于Lucene。
2、Elastic Stack生态（简称ELK Stack，包括 Elasticsearch、Kibana、Beats 和 Logstash）。Elasticsearch是与名为Logstash的数据收集和日志解析引擎以及名为Kibana的分析和可视化平台一起开发的。
a、Elasticsearch 是一个分布式的 RESTful 搜索和分析引擎，可用来集中存储您的数据，以便您对形形色色、规模不一的数据进行搜索、索引和分析。Elasticsearch 是一个基于 JSON 的分布式搜索和分析引擎。
b、Logstash 是一个开源的数据采集引擎，具有实时管道传输功能。Logstash 能够将来自单独数据源的数据动态集中到一起，对这些数据加以标准化并传输到您所选的地方。清理并民主化您的全部数据，将其用于多样化的高级下游分析和可视化用例。Logstash 是动态数据收集管道，拥有可扩展的插件生态系统。
c、Kibana，您可以对自己的 Elasticsearch 进行可视化，还可以在 Elastic Stack 中进行导航，这样您便可以进行各种操作了，从跟踪查询负载，到理解请求如何流经您的整个应用，都能轻松完成。Kibana 可谓 Elastic Stack 的窗户。探索数据并管理堆栈。
d、Beats 是一个面向轻量型采集器的平台，这些采集器可从边缘机器发送数据。Beats 平台集合了多种单一用途数据采集器。它们从成百上千或成千上万台机器和系统向 Logstash 或 Elasticsearch 发送数据。
3、ElasticSearch的下载安装。这里使用elasticsearch-5.4.3.tar.gz，使用CentOS7进行安装。版本进行学习，其实截至目前，Elasticsearch已经发布到Elasticsearch 7.4.0版本了。
将下载好的elasticsearch-5.4.3.tar.gz开始进行安装。
注意：安装elasticsearch之前安装好java，因为elasticsearch是java语言开发的，注意选择java的版本是1.8.0的第20版本以后的，第20之前的会出现很多问题。我使用的1.8.0_181，我用的181版本的，也是出现不少问题。
[root@slaver4 package]# tar -zxvf elasticsearch-5.4..tar.gz -C /home/hadoop/soft/
可以查看其目录结构信息，如下所示：
[root@slaver4 soft]# ls

[root@slaver4 soft]# cd elasticsearch-5.4./

[root@slaver4 elasticsearch-5.4.]#
启动ElasticSearch，如下所示：
启动过程中我的报错了，分析一下错误原因。
[root@slaver4 elasticsearch-5.4.]# sh ./bin/elasticsearch
Java HotSpot(TM) Server VM warning: INFO: os::commit_memory(0x6ac00000, , ) failed; error='Cannot allocate memory' (errno=)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map bytes for committing reserved memory.
# An error report file with more information is saved as:
# /home/hadoop/soft/elasticsearch-5.4./hs_err_pid11491.log
由于elasticsearch5.x版本默认分配jvm空间大小为2g，修改jvm空间分配。（备注：我的虚拟机给了1G的内存，如果硬件较好，可以多给内存）。
再次启动报如下所示错误：

直接删除或备份Elasticsearch-a.b.c/lib目录下面的jna文件：
然后在/home/hadoop/soft/elasticsearch-5.4.3/lib目录下载这个包，wget http://repo1.maven.org/maven2/net/java/dev/jna/jna/4.4.0/jna-4.4.0.jar。

这应该是ElasticSearch不允许使用root用户进行启动。所以先创建一个用户组elsearch，再创建用户elsearch，再将解压缩后的目录权限赋予这个新用户即可。更改elasticsearch文件夹及内部文件的所属用户及组为elsearch:elsearch。切换到elsearch用户再启动。
[root@slaver4 ~]# groupadd elsearch

[root@slaver4 ~]# passwd elsearch

},

}
外网访问，在防火墙开启9200端口命令。或者直接禁掉防火墙，如果本地学习的话。外网还无法访问的话就需要改下配置文件了。

上面的两个错误解决方法如下所示：
错误一，[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]。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。
[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。
* soft nofile
* hard nofile
操作如下所示：
错误二，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。
[root@slaver4 ~]# vim /etc/sysctl.conf
[root@slaver4 ~]# sysctl -p
vm.max_map_count =
[root@slaver4 ~]#
添加内容如下所示：
vm.max_map_count=
操作如下所示：
解决完上述两个错误以后，使用浏览器访问也出现了正常，如下所示：
使用命令行，访问出现如下所示表示正常启动elasticsearch。
如何停止你的elasticsearch呢，如下所示：
方式一，如果是前台启动方式，即进入/home/hadoop/soft/elasticsearch-5.4.3/bin/目录直接使用./elasticsearch启动，直接ctrl+c就可以退出了elasticsearch。
方式二，如果是后台启动elasticsearch的话。./elasticsearch -d。这种后台方式启动。使用jps命令查看进程号，然后使用kill -9 进程号。直接强制杀死的命令。
4、ElasticSearch的实用插件Head的安装。
通过浏览器访问http://192.168.110.133:9200/。返回的是json格式的数据，显示效果不是很友好的，通过Head插件提供的友好的web界面，解决了界面显示的问题。同时Head插件还实现了基本信息的查看，rest请求的模拟，以及数据的基本检索。
使用命令下载elasticsearch head插件，wget https://github.com/mobz/elasticsearch-head/archive/master.zip。
或者使用这种方式安装elasticsearch-head插件。
[elsearch@slaver4 package]$ yum install –y git
[elsearch@slaver4 package]$ git clone https://github.com/mobz/elasticsearch-head.git
我是使用wget下载zip包，直接解压缩操作，安装的elasticearch-head插件。

[root@slaver4 package]#
下载好进行解压缩操作，如下所示：
[root@slaver4 package]# unzip master.zip
由于head插件本质上还是一个nodejs的工程，因此需要安装node，使用npm来安装依赖的包。
下载安装node，wget https://nodejs.org/dist/latest-v8.x/node-v8.16.2-linux-x64.tar.xz，下载完毕进行解压缩操作。
[root@slaver4 package]# wget https://nodejs.org/dist/latest-v8.x/node-v8.16.2-linux-x64.tar.xz
[root@slaver4 package]# ls

[root@slaver4 package]# cd ../soft/
[root@slaver4 soft]# ls
elasticsearch-5.4. elasticsearch-head-master node-v8.16.2-linux-x64
[root@slaver4 soft]#
解压缩完毕，进行配置环境变量。添加完Node环境变量以后刷新配置文件source /etc/profile。
[root@slaver4 soft]# vim /etc/profile
[root@slaver4 soft]# source /etc/profile
配置如下所示：
export NODE_HOME=/home/hadoop/soft/node-v8.16.2-linux-x64
export PATH=$PATH:$NODE_HOME/bin
然后进行查看Node版本验证。如下所示：
注意：Node的版本必须大于等于node6.0版本。
[root@slaver4 soft]# node -v
v8.16.2
[root@slaver4 soft]# npm -v
6.4.
[root@slaver4 soft]#
执行一下npm，npm是Node的一个包安装工具。
[root@slaver4 soft]# ls

[root@slaver4 soft]# cd elasticsearch-head-master/

安装完成以后，运行一下，使用如下命令npm run start，如下所示：
[elsearch@slaver4 elasticsearch-head-master]$ npm run start > elasticsearch-head@0.0. start /home/hadoop/soft/elasticsearch-head-master
> grunt server >> Local Npm module "grunt-contrib-jasmine" not found. Is it installed? Running "connect:server" (connect) task

可以看到head插件默认占用9100端口，浏览器访问http://192.168.110.133:9100/，如下所示。即可显示head插件界面。
由于elasticsearch和elasticsearch-head插件是属于两个不同的进程的，他们之间的访问是存在跨域问题的。
[root@slaver4 ~]# cd /home/hadoop/soft/elasticsearch-
-bash: cd: /home/hadoop/soft/elasticsearch-: No such file or directory
[root@slaver4 ~]# cd /home/hadoop/soft/elasticsearch-
elasticsearch-5.4./ elasticsearch-head-master/
[root@slaver4 ~]# cd /home/hadoop/soft/elasticsearch-5.4./
[root@slaver4 elasticsearch-5.4.]# ls
bin config data hs_err_pid11491.log lib LICENSE.txt logs modules NOTICE.txt plugins README.textile
[root@slaver4 elasticsearch-5.4.]# vim config/elasticsearch.yml
在/home/hadoop/soft/elasticsearch-5.4.3/config/elasticsearch.yml配置文件中添加如下所示配置。解决跨域访问的问题、支持所有的域名。
# 是否支持跨域
http.cors.enabled: true
#
# *表示支持所有域名
http.cors.allow-origin: "*"
此时，后台启动elasticsearch（切记，使用自己创建的用户，不能使用root用户哦，./elasticsearch -d），启动elasticsearch-head插件（切记，使用自己创建的用户，npm run start）。
通过head插件连接elasticsearch服务。输入elasticsearch服务地址http://192.168.110.133:9200/，点击连接，右边显示黄色信息说明连接成功，至此elasticsearch-head插件安装成功。
注意：green绿色代表集群健康，正常运行。yellow黄色代表集群健康不是很好，但是集群可以使用。red红色代表集群状态很差，搜索可以使用，但是可能出现丢失数据的情况。
5、安装grunt，可以使用后台启动elasticsearch-head插件（这里的操作，我是执行完以上进行的操作，目的是为了后台可以启动head插件的），操作如下所示：
安装grunt，如下所示：
[elsearch@slaver4 elasticsearch-head-master]$ cd elasticsearch-head-master
[elsearch@slaver4 elasticsearch-head-master]$ npm install -g grunt --registry=https://registry.npm.taobao.org
注意：在elasticsearch-head目录下node_modules/grunt下如果没有grunt二进制程序，需要执行：
[elsearch@slaver4 elasticsearch-head-master]$ cd elasticsearch-head-master
[elsearch@slaver4 elasticsearch-head-master]$ npm install grunt --save
[elsearch@slaver4 soft]$ cd elasticsearch-head-master/

run `npm audit fix` to fix them, or `npm audit` for details
下面的配置可以修改也可以不修改的，我这里修改了。
修改elasticsearch-head下Gruntfile.js文件，默认监听在127.0.0.1下9200端口：
添加hostname: '192.168.110.133',这个配置。
connect: {
server: {
options: {
hostname: '192.168.110.133',
port: ,
base: '.',
keepalive: true
}
}
}
修改 _site/app.js，修改http://localhost:9200字段到本机ES端口与IP：
在命令模式，即可以使用:/localhost搜索找到localhost，然后修改如下配置。显示行号，也是在命令模式，使用:set nu既可以显示行号。
将此配置
"http://localhost:9200"; 修改为了
"http://192.168.110.133:9200";
Vim的三种工作模式。
后台启动elasticsearch-head插件，如下所示：
在/home/hadoop/soft/elasticsearch-head-master/node_modules/grunt/bin目录下面，使用此命令后台启动。./grunt server &
