安装ElasticSearch下载安装包

ES官网下载es和kibana:https://www.elastic.co/cn/start，并上传至服务器

运行ElasticSearch

解压两个tar包后，先进入Elasticsearch输入命令

./bin/elasticsearch启动es

linux启动时会看到如下命令行

? Elasticsearch security features have been automatically configured!? Authentication is enabled and cluster connections are encrypted.??Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):_DmmGurIhw6H4mNs27wH??HTTP CA certificate SHA-256 fingerprint:e5532ec5596cbeccbc6515f40a3e6cc486bfad12079e2ab0420f32deea002c23??Configure Kibana to use this cluster:? Run Kibana and click the configuration link in the terminal when Kibana starts.? Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):eyJ2ZXIiOiI4LjIuMCIsImFkciI6WyIxMC4wLjEyLjIzMDo5MjAwIl0sImZnciI6ImU1NTMyZWM1NTk2Y2JlY2NiYzY1MTVmNDBhM2U2Y2M0ODZiZmFkMTIwNzllMmFiMDQyMGYzMmRlZWEwMDJjMjMiLCJrZXkiOiJZQWpneTRBQktfRHFQQUFrSURUbTpnUlZpNEMySlRCYTlwZ045QzIwTVBRIn0=??Configure other nodes to join this cluster:? On this node:? Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.? Uncomment the transport.host setting at the end of config/elasticsearch.yml.? Restart Elasticsearch.? On other nodes:? Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.

这里需要及时保存，用上述参数举例含义

elasticsearch超级管理员：elastic/_DmmGurIhw6H4mNs27wH

下面的JWTToken为kibana初始化认证时所需要，token设置为30分钟过期，如果token过期可以输入如下命令重新生成token

bin/elasticsearch-create-enrollment-token -s node

成功启动

浏览器输入地址

https://10.0.12.230:9200/

建议9200端口不要被占用，如果被占用，会导致Kibana启动异常麻烦

会提示这是个不安全的认证网站，谷歌浏览器，点击任意空白处

键盘输入thisisunsafe回车即可成功启动ElasticSearch

错误排查

在启动时一般会遇到如下两种错误

内存不够

进入config目录中，vim jvm.options文件,修改jvm参数

不能使用root用户启动

按如下命令输入

# 新增用户adduser elastic# 设置密码passwd elastic输入密码:terra123# 分配权限chown -R elastic /opt/elasticsearch# 切换用户su elastic# 进入es所在目录，启动es./bin/elasticsearch启动Kibana参数配置

进入之前解压的kibana中，进入config目录，修改kibana的host地址，目的在于可以通过客户端浏览器访问到kibana地址，否则浏览器输入地址+端口访问无效

# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.# The default is 'localhost', which usually means remote machines will not be able to connect.# To allow connections from remote users, set this parameter to a non-loopback address.server.host: "10.0.12.230"

./bin/kibana启动Kibana

运行成功

Kibana初次启动后终端会打印如下地址

在浏览器输入地址即可进入Kibana页面，首次配置需要使用初次启动ElasticSearch中的JWT-Token，将token复制粘贴到输入框，即可完成Kibana的初始化配置

Kibana has not been configured.Go to http://10.0.12.230:5601/?code=307455 to get started.原文：https://juejin.cn/post/7098579476522958856
