安装ElasticSearch

下载安装包

ES官网下载es和kibana: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.

ℹ️  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  _DmmGurIhw6H4mNs27wH

ℹ️  HTTP CA certificate SHA-256 fingerprint:
  e5532ec5596cbeccbc6515f40a3e6cc486bfad12079e2ab0420f32deea002c23

ℹ️  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=

ℹ️  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.
