ELK开启账户密码认证详细操作 _操作

听闻少年二字，当与平庸相斥。这篇文章主要讲述ELK开启账户密码认证详细操作相关的知识，希望能为你提供帮助。
环境:

ElasticSearch版本：7.13.2

介绍：

kibana只是一个视图页面，真正工作的是Elasticsearch。

注意：

下边有关es的操作需要所有节点执行。

?
创建es节点之间SSL证书1、在es主节点生成 elastic-stack-ca.p12文件

# ./bin/elasticsearch-certutil ca
Please enter the desired output file [elastic-stack-ca.p12]:#回车
Enter password for elastic-stack-ca.p12 : #CA证书的密码,回车
# ls
binconfigdataelastic-stack-ca.p12jdklibLICENSE.txtlogsmodulesnohup.outNOTICE.txtpluginsREADME.asciidoc

2、在es主节点生成 elastic-certificates.p12文件

./elasticsearch-certutil cert --ca elastic-stack-ca.p12
Enter password for CA (elastic-stack-ca.p12) : # CA证书的密码，直接回车
Please enter the desired output file [elastic-certificates.p12]: # 默认
Enter password for elastic-certificates.p12 : # 证书密码，直接回车

3、复制elastic-stack-ca.p12、elastic-certificates.p12到各节点的config目录

cp elastic-stack-ca.p12 elastic-certificates.p12config/

4、修改elastic-stack-ca.p12 、 elastic-certificates.p12属主

# chown elk. config/elastic-certificates.p12
# chown elk. config/elastic-stack-ca.p12

5、其他节点省略......
配置es1、修改es配置文件：elasticsearch.yml，添加如下配置，其他节点配置相同

# vim ../config/elasticsearch.yml
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

2、重启es

systemctl restart elasticsearch

3、es的bin目录下执行命令设置初始密码，会设置下边六个账户的密码

# ./elasticsearch-setup-passwords interactive
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,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_system]:
Reenter password for [kibana_system]:
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_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]

4、修改kibana的配置文件

# vim kibana.yml
elasticsearch.username: "kibana_system"
elasticsearch.password: "kibana_system"# 密码

5、重启kibana服务

# systemctl restart kibana

6、修改logstash配置文件

# vim /opt/logstash-7.13.2/config/new.conf
output
elasticsearch
hosts=> ["xxxx:9200","xxxxxx:9200"]
index => "%[type]-%+YYYY.MM.dd"
user => "elastic"# 新增
password => "elastic"# 新增

7、重启logstash服务
