--------------------------- Security autoconfiguration information ------------------------------
Authentication and authorization are enabled.
TLS for the transport and HTTP layers is enabled and configured.
The generated password for the elastic built-in superuser is : 5gCSq67v=vhdM7N6Yrak
If this node should join an existing cluster, you can reconfigure this with
'/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token <token-here>'
after creating an enrollment token on your existing cluster.
You can complete the following actions at any time:
Reset the password of the elastic built-in superuser with
'/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic'.
Generate an enrollment token for Kibana instances with
'/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana'.
Generate an enrollment token for Elasticsearch nodes with
'/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node'.
-------------------------------------------------------------------------------------------------
### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
### You can start elasticsearch service by executing
sudo systemctl start elasticsearch.service
????从安装过程可以看到，elastic 超级账户的密码是 5gCSq67v=vhdM7N6Yrak
????配置文件不做调整，直接启动 elasticsearch，并且登录验证。
安装 Kibana
????接着安装 Kibana
wget https://artifacts.elastic.co/downloads/kibana/kibana-8.2.3-x86_64.rpm
rpm -ivh kibana-8.2.3-x86_64.rpm
????Kibana配置文件可以不做修改，为了便于操作，能从其他主机访问，本人修改了 server.host
server.host: "0.0.0.0"
????启动Kibana，查询到 Kibana 配置网址，其中 code 取值每次安装都不同：
????打开浏览器界面进行 Kibana 与 Elasticsearch 的连接配置：
????页面需要输入 Token，使用以下命令生成：
/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana
????将 Token 复制粘贴：
????进入下一页，需要输入验证码。使用以下命令生成验证码：
/usr/share/kibana/bin/kibana-verification-code
????输入验证码。最后，Elasticsearch 和 Kibana 的安装配置完成。
