注意

如果是集群的话，需要使用ssl的证书，只开XPACH的话，在设置账号密码会有报错，如下图

操作步骤

一、修改elasticsearch.yml的配置文件，每个节点都要加上如下标红的配置，并重启3个节点的ES

	[root@ES1 ~]# grep "^[a-Z]"  /data/elasticsearch-7.8.0/config/elasticsearch.yml

		cluster.name: Log
		node.name: node-1
		path.data: /data/elk/data
		path.logs: /data/elk/logs
		bootstrap.memory_lock: true
		network.host: 172.130.211.18
		http.port: 9200
		discovery.seed_hosts: ["172.130.211.18", "172.130.211.19", "172.130.211.20"]
		cluster.initial_master_nodes: ["node-1","node-2","node-3"]
		http.cors.enabled: true 
		http.cors.allow-origin: "*"
		http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE
		http.cors.allow-headers: "X-Requested-With, Content-Type, Content-Length, X-User"
		xpack.security.enabled: true
		xpack.security.transport.ssl.enabled: true
		xpack.security.transport.ssl.verification_mode: certificate
		xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
		xpack.security.transport.ssl.truststore.path: elastic-certificates.p12

[root@ES1 ~]# sudo -u elasticsearch /data/elasticsearch-7.8.0/bin/elasticsearch -d

二、生成证书，过程期间什么都不需要输入一直回车回车就可以了

[root@ES1 ~]# sudo -u elasticsearch sh elasticsearch-certutil ca
[root@ES1 ~]# sudo -u elasticsearch sh elasticsearch-certutil cert --ca elastic-stack-ca.p12

然后就会生成两个文件elastic-stack-ca.p12和elastic-certificates.p12，然后把elastic-certificates.p12放在每个节点的config目录下面

三、设置账号密码

[root@ES1 ~]# sudo -u elasticsearch sh elasticsearch-setup-passwords interactive

四、修改Kibana的配置

		[root@ES1 config]# grep "^[a-Z]"  /etc/kibana/kibana.yml 

		server.port: 5601
		server.host: "0.0.0.0"
		elasticsearch.hosts: ["http://172.130.211.18:9200"]
		elasticsearch.username: "kibana"
		elasticsearch.password: "您的密码！"
		i18n.locale: "zh-CN"

[root@ES1 config]# systemctl restart kibana.service

五、登陆Kibana
