Kibana_on_ES 配置教程

配置过程

实验环境: Kibana 版本8.7.1, Elasticsearch 版本8.7.1，在 wsl2-ubuntu22.0.4 上部署

作者在启动 Kibana 的时候，遇到了找不到 nodejs 的报错，最后发现是 kibana-x.x.x/node 文件权限的问题，只需要用 chmod 755 kibana-x.x.x/node 即可

ES 单节点配置

修改 config/elasticsearch.yml 文件，添加如下内容，ip地址输入本机wsl地址，可以通过 hostname -I 命令活动

cluster.name: es-8.7.1
node.name: es-9201
path.data: ~\elastic\data\9201
path.logs: ~\elastic\logs\9201
network.host: 172.21.168.87
http.port: 9201
transport.port: 9301

在 kibana-8.7.1/ 新建 data 和 logs 文件夹

运行启动命令

1	./elastic/elasticsearch-8.7.1/bin/elasticsearch

启动后会在控制台输出账号的密码和用于 kibana 的 enrollment token，先保存下来，待会有用

-------------------------------------------------------------------------------------------------------------------------> Elasticsearch security features have been automatically configured!
-> Authentication is enabled and cluster connections are encrypted.

->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  rlF=_=7wFIrdNj6Zh9Z2

->  HTTP CA certificate SHA-256 fingerprint:
  a15c8cfcb300affed0dbdf73c318339366b8d8ba076657056e6b85170669d0d6

->  Configure Kibana to use this cluster:
* Run Kibana and click the configuration link in the terminal when Kibana starts.
* Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

->  Configure other nodes to join this cluster:
* On this node:
  - Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
  - Uncomment the transport.host setting at the end of config/elasticsearch.yml.
  - Restart Elasticsearch.
* On other nodes:
  - Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.

如果没有保存下来、token过期，也可以手动重置

把 ES 启动后，就可以通过以下两条命令重置

# 重置密码
./elastic/elasticsearch-8.7.1/bin/elasticsearch-reset-password -u elastic
# 重置 token
./elastic/elasticsearch-8.7.1/bin/elasticsearch-create-enrollment-token -s kibana --url "https://172.21.168.87:9201"
