Elasticsearch7.3开启x-pack验证

原文 Elasticsearch7开启x-pack验证

前言

在Elasticsearch7.3，x-pack已经作为默认的插件集成在Elasticsearch里面了，所以无需在bin/elasticsearch-plugin install x-pack了，直接在配置文件中启用就可以了。

	[root@localhost bin]# ./elasticsearch-plugin install x-pack
	ERROR: this distribution of Elasticsearch contains X-Pack by default

开启x-pack

参考官方文档，开启x-pack只需要在elasticsearch的配置文件elasticsearch.yml文件中新增如下配置即可：

	# 开启x-pack安全验证
	xpack.security.audit.enabled: true
	xpack.license.self_generated.type: basic
	# 如果是basic license的话需要加入下面这一行，不然的话restart elasticsearch之后会报错。
	xpack.security.transport.ssl.enabled: true

设置密码

	[root@elk elasticsearch]# 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]

密码设置完成后需要在相对应的服务中增加elasticsearch的账号密码，例如kibana、logstash。
kibana设置：

	elasticsearch.username: "elastic"
	elasticsearch.password: "123456"
