elasticsearch开启简单密码认证

启动 Elasticsearch 程序

./elasticsearch -d

$ ./elasticsearch-setup-passwords interactive
Unexpected response code [500] from calling GET http://127.0.0.1:9200/_security/_authenticate?pretty
It doesn't look like the X-Pack security feature is enabled on this Elasticsearch node.
Please check if you have enabled X-Pack security in your elasticsearch.yml configuration file.

ERROR: X-Pack Security is disabled by configuration.

需要在elasticsearch的配置文件elasticsearch.yml配置X-Pack

$ vim ../config/elasticsearch.yml
	http.cors.enabled: true
	http.cors.allow-origin: "*"
	http.cors.allow-headers: Authorization
	xpack.security.enabled: true
	xpack.security.transport.ssl.enabled: true

再次尝试创建密码

./elasticsearch-setup-passwords interactive

如果安装了kibana记得添加认证信息

	elasticsearch.username: "elastic"
	elasticsearch.password: "passwd"

POST /_security/user/elastic/_password
{
  "password": "123456"
}
