一般elasticsearch是没有设置用户名、密码的,数据有安全性问题。需要给elasticsearch访问的时候设置用户名、密码。当用kibana访问时需要输入用户名、密码后才能登录。

1、修改elasticsearch.yml(报无效认证),重启elasticsearch

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

如上修改后,双击启动elasticsearch.bat文件报如下错:

elasitcsearch 开启认证后,报DecoderException: javax.net.ssl.SSLHandshakeException: No available authentic异常

=================================================================

解决办法参考:elasitcsearch 开启认证后,报DecoderException: javax.net.ssl.SSLHandshakeException: No available authentic异常_猿界汪汪队的博客-CSDN博客

第一步:在ES的根目录生成CA证书

elasticsearch-7.4.2\bin>elasticsearch-certutil ca
中间需要设置密码,直接回车可以不设置(慎重考虑)。

第二步:使用第一步生成的证书,产生p12密钥

elasticsearch-7.4.2\bin>elasticsearch-certutil cert --ca elastic-stack-ca.p12
此时文件大概如下:

第三步:在config目录下创建certs目录

第四步:拷贝两个p12文件至certs目录

第五步:修改设置

修改elasticsearch.yml配置如下(http开头的不改,替换xpack开头的就行):

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: certs/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: certs/elastic-certificates.p12


第六步:重启ES,错误消失


2、修改elasticsearch密码(要java11问题解决),重启elasticsearch

elasticsearch-7.4.2\bin>elasticsearch-setup-passwords interactive

=================================================================

解决方法参考:

ElasticSearch 提示 future versions of Elasticsearch will require Java 11解决方法_AB教程网
如果是window系统,打开elasticsearch-env.bat
找到42行,注释掉默认使用系统的jdk的设置,增加使用es里自带的jdk11

 我的修改如下:

if defined JAVA_HOME (
rem  set JAVA="%JAVA_HOME%\bin\java.exe"
  set JAVA="C:\Users\lenovo\Desktop\QWJS\Archive\elasticsearch-7.5.1\jdk\bin\java.exe"
  set JAVA_TYPE=JAVA_HOME
) else (
rem  set JAVA="%ES_HOME%\jdk\bin\java.exe"
  set JAVA="C:\Users\lenovo\Desktop\QWJS\Archive\elasticsearch-7.5.1\jdk\bin\java.exe"
rem  set JAVA_HOME="%ES_HOME%\jdk"
  set JAVA_HOME="C:\Users\lenovo\Desktop\QWJS\Archive\elasticsearch-7.5.1\jdk"
  set JAVA_TYPE=bundled jdk
)

3、给elasticsearch设置密码(前提执行了前面1、2、然后启动elasticsearch成功的状态下)

参考网址:

设置elasticsearch 7.x用户名和密码_程裕强的博客-CSDN博客_elasticsearch密码设置

elasticsearch-7.4.2\bin>elasticsearch-setup-passwords interactive

D:\app\elasticsearch-7.4.2\bin>elasticsearch-setup-passwords interactive
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,logstash_system,beats_system,remote_monitoring_user.
You will be prompted to enter passwords as the process progresses.
Please confirm that you would like to continue [y/N]y

Enter password for [elastic]:
Reenter password for [elastic]:
Enter password for [apm_system]:
Reenter password for [apm_system]:
Enter password for [kibana]:
Reenter password for [kibana]:
Enter password for [logstash_system]:
Reenter password for [logstash_system]:
Enter password for [beats_system]:
Reenter password for [beats_system]:
Enter password for [remote_monitoring_user]:
Reenter password for [remote_monitoring_user]:
Changed password for user [apm_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]

D:\app\elasticsearch-7.4.2\bin>

 密码修改完成后、访问elasticsearch。

浏览器输入http://localhost:9200需要输入用户名:elastic   密码:自己设置的密码

4、连接elasticsearch的插件Kibana设置链接的地址跟连接用户名,启动后访问全文检索数据

修改kibana组件config文件夹下kibana.yml

 

 修改完成保存后,点击kibana-7.5.1-windows-x86_64\bin下面的kibana.bat启动

浏览器访问http://localhost:8088/,输入登陆用户名:elastic  密码:前面elasticsearch设置的密码

登陆后查看索引库信息:

5、由于elasticsearch设置了用户名、密码,所以在全文检索的代码也要做修改把用户名、密码带进去连接全文检索
