Elasticsearch 7.17.7开启x-pack

1、ES配置文件  elasticsearch.yml

cluster.name: elasticsearch
node.name: node-1
network.host: 0.0.0.0
discovery.type: single-node
xpack.security.enabled: true
xpack.security.authc.api_key.enabled: true

设置密码

/usr/share/elasticsearch/bin/elasticsearch-setup-passwords auto

会自动生成如下用户和密码

Changed password for user apm_system
PASSWORD apm_system = lptBmZuUxXFhapVn6Wp9

Changed password for user kibana_system
PASSWORD kibana_system = YdL4LTq8xrLKA9yp5VuG

Changed password for user kibana
PASSWORD kibana = YdL4LTq8xrLKA9yp5VuG

Changed password for user logstash_system
PASSWORD logstash_system = L721FwcFxVZhits3x0GC

Changed password for user beats_system
PASSWORD beats_system = 3K3IDdptiDy64aboWmaH

Changed password for user remote_monitoring_user
PASSWORD remote_monitoring_user = zNaRrGQAt0cbmbflmrCa

Changed password for user elastic
PASSWORD elastic = cWssWIcIi8NPGIuBhlYU

其中 

kibana用户：配置为kibana配置文件

elastic用户：做登录认证

2、kibana.yml

elasticsearch.hosts: http://elasticsearch:9200
elasticsearch.username: "kibana"
elasticsearch.password: "YdL4LTq8xrLKA9yp5VuG"
i18n.locale: zh-CN
server.host: "0"
