elasticsearch官网下载比较慢有时还打不开可以通过https://elasticsearch.cn/download/下载先找到对应的版本最好使用迅雷下载秒下的我的下载速度可以达到40M/S
解压安装
安装 elasticsearch
解压后点击elasticsearch-7.10.0\bin\elasticsearch.bat运行成功后输入http://120.0.0.1:9200可以访问说明ES启动成功
安装 kibana
点击kibana-7.10.0-windows-x86_64\bin\kibana.bat 启动成功后输入http://localhost:5601/即可进入kibana 配置登录账号密码
ealsticsearch设置账号密码
打开config/ealsticsearch.yml增加开启密码配置然后重启ealsticsearch
xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true输入.\bin\elasticsearch-setup-passwords.bat interactive设置密码这里有一些ES内置的账号密码比如kibana_system这个账号密码需要配置到kibana.yml中这里要记一下本地测试我都设置成123456好了生产环境密码强度要设置大点不可用简单密码。
PS D:\service\ES\elasticsearch-7.10.0 .\bin\elasticsearch-setup-passwords.bat interactive
