Elasticsearch示例版本：7.9.2

一、设置密码

1.需要在配置文件中开启x-pack验证, 修改config目录下面的elasticsearch.yml文件，在里面添加如下内容,并重启es.

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true

2，进入es的安装根目录bin下，E:\software\es\elasticsearch-7.9.2\bin

执行设置用户名和密码的命令,这里需要为4个用户分别设置密码，elastic, kibana, logstash_system,beats_system

elasticsearch-setup-passwords interactive

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

 

3：将kibana.yml添加：

elasticsearch.username: "elastic"
elasticsearch.password: "xxxx"

4，重启即可。

5,修改密码时，将第一步配置删除，然后重启es，将.security-7的索引删除即可。

然后重新1-4步骤。
