Elasticsearch6.4.3安装

 Linux内存一定要1g以上!

 首先要有jdk环境 要求1.8版本以上   elasticsearch是Java写的

 

 将上传的 elasticSearch安装包解压

cd /home/elasticsearch/elasticsearch-6.4.3/config

1、 修改elasticsearch.yml

network.host: 192.168.91.7

http。port:9200    #这是HTTP协议外部通信的端口号   9300内部通信端口号

 

如果此时启动,会报错 root不能启动的哦 不能通过root账号启动 这是属于自身的安全策略,解决方案,非root就可以了哈哈

 

因为安全问题elasticsearch 不让用root用户直接运行,所以要创建新用户

首先创建个分组: groupadd esUsers

                              useradd  esUser01 -g  esUsers -p 123

                              chown -R esUser01:esUsers   elasticsearch-6。4。3

                              su   esUser01   #切换登录用户

【参考:

第一步:liunx创建新用户  adduser esUsers    然后给创建的用户加密码 passwd XXX    输入两次密码。

第二步:切换刚才创建的用户 su esUsers 然后执行elasticsearch  会显示Permission denied 权限不足。

第三步:给新建的XXX赋权限,chmod 777 *  这个不行,因为这个用户本身就没有权限,肯定自己不能给自己付权限。所以要用root用户登录付权限。

第四步:root给esUser赋权限,chown -R XXX /你的elasticsearch安装目录。

然后执行成功。】

 这样启动仍然是会报错的

解决方案:

 用root权限去做!

vi /etc/sysctl.conf

添加:  vm.max_map_count=655360  然后保存

然后 cd /etc

输入: sysctl -p

 

继续启动,继续报错:

[2]: max number of threads [1024] for user [esUser01] is too low, increase to at least [4096]

[2019-01-21T01:03:49,017][INFO ][o.e.x.m.j.p.NativeController] Native controller process has stopped - no new native processes can be started

 解决方案:继续用root去修改

vi /etc/security/limits.conf

加入:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

 

 必须重启! 重启才可以生效

 

继续报错!

[1]: max number of threads [1024] for user [esUser01] is too low, increase to at least [4096]

 

解决:root下

vi /etc/security/limits.d/90-nproc.conf

 

 

 

 

 

在操作时候竟然出现了错误:

这个错误竟然是空格造成的! 醉了 这种格式 很让人不开心啊

解决方案:

 

 启动,继续报错!!

 system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

 分析和解决:

出现错误的原因:是因为centos6。x操作系统不支持SecComp,而elasticsearch 5。5。2默认bootstrap。system_call_filter为true进行检测,所以导致检测失败,失败后直接导致ES不能启动。

在elasticsearch。yml中添加配置项:bootstrap。system_call_filter为false:

bootstrap.system_call_filter: false

此时可以完美解决了!

启动成功!

 

关闭防火墙后访问:

http://192.168.91.7:9200/

9200端口可以提供Restful api接口 进行增删改查操作

 

下面安装可视化界面: Kibana

Kibana是一个开源的分析和可视化平台,设计用于和Elasticsearch一起工作。
你用Kibana来搜索,查看,并和存储在Elasticsearch索引中的数据进行交互。
你可以轻松地执行高级数据分析,并且以各种图标、表格和地图的形式可视化数据。
Kibana使得理解大量数据变得很容易。它简单的、基于浏览器的界面使你能够快速创建和共享动态仪表板,实时显示Elasticsearch查询的变化。

 

解压安装包后修改配置文件:

vim config/kibana。yml

# 将默认配置改成如下:

server。port: 5601

server.host: "192.168.91.7"

elasticsearch.url: "http:// 192.168.91.7:9200"   # 如果是集群 写集群地址

 

(自己的ip端口号  和 读取的 es的ip端口号)

启动Kibana

./bin/kibana

 

http://192.168.91.7:5601/app/kibana

 

 

1。查找ES进程

ps -ef | grep elastic

2.杀掉ES进程

kill -9 2382(进程号)

3。重启ES

sh elasticsearch -d
