一、首先在elasticsearch配置文件中開啟x-pack驗證, 修改config目錄下面的elasticsearch.yml文件，在里面添加如下內容,並重啟
xpack.security.enabled: true
二、在elasticsearch的bin下執行elasticsearch-setup-passwords interactive命令，elasticsearch-setup-passwords是elasticsearch命令行工具用來設置密碼的，已交互方式為內置的各個用戶設置密碼
➜ sh 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]
三、配置kibana，使其能夠訪問elasticsearch
修改kibana配置文件,config下的kibana.yml,添加如下內容
elasticsearch.username: "elastic" elasticsearch.password: "123456"
