安装elasticsearch版本：elasticsearch-6.2.2.tar.gz  
安装包下载路径（里边有6.2.2版本、6.4.2版本和jdk1.8的包）：

1.安装elasticsearch参考：[http://www.cnblogs.com/hanyinglong/p/5409003.html][http_www.cnblogs.com_hanyinglong_p_5409003.html]  
说一下我自己的做法  
查看一下自己的java环境换成jdk1.8，这个网上一大堆参考文档。  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world]  
这里大概说一下，就是解压包然后配置环境变量  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 1]  
路径根据自己解压的位置去指定。最后source /etc/profile

> mkdir -p /data/software/elasticsearch

创建用户，因为启动es不能用root用户。

> sudo adduser es

然后敲个Y完事。  
cd /home/下看一下有没有家目录。  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 2]  
然后到下载包存放路径解压包。

> sudo tar -zxvf elasticsearch-2.3.1.tar.gz  
> sudo mv elasticsearch-2.3.1 /data/software/elasticsearch  
> sudo chown -R es.es /data/software/elasticsearch

我们看一下es的文件结构：  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 3]  
我们每个机器上做一个es，这个不是建议也不是什么经验之谈，因为你是运维（背锅侠），你的要注意都做一台机器上万一机器宕机了，数据可就全没了。最普通小白安全的做法就是3台机器每个服务器上只做一个节点（此做法允许且只允许任意一台服务器宕机），不了解es为什么这样做的请读我的技术点篇。  
接下来我们修改elasticsearch的配置文件。

![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 4]

修改完成以后我们切换到es用户去启动es，记住：切换到es用户！切换到es用户！！切换到es用户！！！  
要不就会出现如下情况：  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 5]  
但是你可能会遇到如下情况哈哈，不要慌：基本操作。

> \[1\]: max virtual memory areas vm.max\_map\_count \[65530\] is too low, increase to at least \[262144\]  
> 等问题，修改几个配置文件：
> 
> /etc/profile文件最后边添加：ulimit -SHn 65536  
> /etc/security/limits.conf文件最后添加：
> 
>  *  soft nofile 65536
>  *  hard nofile 65536
>  *  soft nproc 4096
>  *  hard nproc 4096

然后我们把这些配置应用到es用户可以看一下ulimit -Hn  
一切正常后我们再启动  
![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 6]  
我们在网页访问ip:9200出来如下内容表示成功

![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 7]

其他的2个节点按上边的操作正常操作完毕（可能会出现的一个问题启动前先删除/data/software/elasticsearch/data/节点目录下的数据），出现如上图恭喜你成功了.  
接下来就是安装比较麻烦又low的elasticsearch-head，也给大家操作一下吧，（生产环境能不用head插件尽量别用，因为安全性特别差暴露给别人，别人可以上你的es对节点进行操作）  
elasticsearch 5.x之后不支持直接plugin安装head插件，而是将head作为一个独立的服务安装的，首先需要安装依赖的node，npm，grunt  
apt-get install npm  
apt-get install nodejs-legacy  
npm install -g grunt  
npm install -g grunt-cli  
下载elasticsearch-head，我解压到目录/data/software/elasticsearch-head，将目录用户改为es  
然后修改配置

1.修改head的连接地址 elasticsearch-head/\_site/app.js

> this.base\_uri = this.config.base\_uri || this.prefs.get("app-base\_uri") || "[http://localhost:9200][http_localhost_9200]";

localhost改为自己的ip  
2.修改服务器的监听地址elasticsearch-head/Gruntfile.js

>     connect: {  
>                server: {  
>                    options: {  
>                        port: 9100,  
>                        base: '.',  
>                        keepalive: true  
>                    }  
>                }  
>            }

options中添加 hostname: '\*'  
3.修改elasticseach的配置文件elasticsearch.yml, 修改对应的ip以及跨域的设置，添加：

http.cors.enabled: true

http.cors.allow-origin: "\*"  
3 在elasticsearch-head下运行: grunt server  
3.1 但是会出现错误提示（当时命令敲的npm start，应该是一样的）：

> root@ubuntu:/usr/local/kencery/elasticsearch-head\# npm start
> 
> > elasticsearch-head@0.0.0 start /usr/local/kencery/elasticsearch-head

看提示大概有提到版本不是最新的问题，所以就抱着试一试的心态去升级npm以及node

> npm cache clean -f  
> npm install -g n  
> n stable  
> npm install npm@latest -g

再查看下版本，会看到

> elasticsearch@ubuntu:~$ node -v  
> v10.4.0  
> elasticsearch@ubuntu:~$ npm -v  
> 6.1.0

3.2 但是运行grunt server依然报错：

> grunt hasn't been installed locally to your project

参考 [https://segmentfault.com/q/1010000004172559/a-1020000004193932][https_segmentfault.com_q_1010000004172559_a-1020000004193932]， 执行：

> npm install grunt --save-dev

3.3 再次运行，依然报错：  
elasticsearch@ubuntu:/usr/local/kencery/elasticsearch-head$ grunt server

> Local Npm module "grunt-contrib-clean" not found. Is it installed?  
> Local Npm module "grunt-contrib-concat" not found. Is it installed?  
> Local Npm module "grunt-contrib-watch" not found. Is it installed?  
> Local Npm module "grunt-contrib-connect" not found. Is it installed?  
> Local Npm module "grunt-contrib-copy" not found. Is it installed?  
> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?  
> Warning: Task "connect:server" not found. Use --force to continue.

然后我干脆把有关grunt的都装了一遍最新的：

> npm install grunt@latest  
> npm install grunt-cli@latest  
> npm install grunt-contrib-copy@latest  
> npm install grunt-contrib-concat@latest  
> npm install grunt-contrib-uglify@latest  
> npm install grunt-contrib-clean@latest  
> npm install grunt-contrib-watch@latest  
> npm install grunt-contrib-connect@latest  
> npm install grunt-contrib-jasmine@latest

4.4 最后grunt server终于可以启动了：

> elasticsearch@ubuntu:/usr/local/kencery/elasticsearch-head$ grunt server  
> (node:1527) ExperimentalWarning: The http2 module is an experimental API.  
> Running "connect:server" (connect) task  
> Waiting forever...  
> Started connect web server on [http://localhost:9100][http_localhost_9100]

![Elasticsearch集群搭建1Welcome to my ELK world！][Elasticsearch_1Welcome to my ELK world 8]

可以看到elasticsearch服务的端口是9200，head插件服务的端口是9100，我们访问head然后head再访问的elasticsearch。
