kibana开启访问登录认证

编辑es配置文件，添加以下内容开启es认证
vim /etc/elasticsearch/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

重启es
systemctl restart elasticsearch

---

设置es密码
/usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive

会一次设置多种账户的密码

---

暂停相关服务,避免kibana报错

systemctl stop elasticsearch.service
systemctl stop logstash.service 
systemctl stop kibana.service

编辑kibana配置文件，配置es的账户和密码
vim /etc/kibana/kibana.yml

elasticsearch.username: "elastic"
elasticsearch.password: "前面设置的es密码"

启动前面停掉的服务

systemctl start elasticsearch.service
systemctl start logstash.service 
systemctl start kibana.service 

---

访问kibana进行测试
已经开启了认证

---

es设置了密码后会遇到，日志写入es中断的情况，
因为日志写入es时候需要密码，所以要给logstash配置账户和密码

例：

output { #输出源stdout {}if "test_host123" in [tags] {  elasticsearch {hosts => "http://es地址:9200"user => "elastic"   #配置账户password => "passwd"  #配置密码manage_template => false  #默认值是true,false是关闭logstash自动管理模版的功能，自定义模版的话就设置为falseindex => "test_host123-%{+yyyy.MM}" }}}

保存后重启logstash，日志即可正常打入es。
