Hi,

To generate a root-ca.pem file for Elasticsearch, you can use the `elasticsearch-certutil` tool that comes with Elasticsearch.

For more information, you can refer to the following documentation:

- [Setting up your own certificate authority (CA)](https://www.elastic.co/guide/en/elasticsearch/reference/current/certutil.html#certutil-ca)
- [Generating a certificate for your Elasticsearch node](https://www.elastic.co/guide/en/elasticsearch/reference/current/certutil.html#certutil-cert)
- [Configuring Elasticsearch to use the generated certificates](https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-tls.html#node-certificates)

Regards

Many thanks for the reply ,do you think is it a correct way to generate root-ca  
bin/elasticsearch-certutil ca --ca-dn "CN=root-ca" --days 365 --pem --out /etc/elasticsearch/root-ca.pem
