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
