Unable to retrieve version information from Elasticsearch nodes. self signed certificate in certificate chai

这个错误通常意味着Elasticsearch节点使用了自签名的SSL证书,而您的客户端无法验证该证书的有效性。
要解决这个问题,您可以采取以下几种方法之一:
1. 将证书添加到您的客户端信任列表中。这通常可以通过将证书文件放置在特定目录中并重新加载证书存储来完成。
2. 在连接Elasticsearch节点时,使用不验证证书的选项。但是请注意,这会降低安全性。
3. 更改Elasticsearch节点配置以使用由受信任的证书机构颁发的SSL证书。
具体操作可以参考Elasticsearch的官方文档或者相关社区的帖子。

[ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. self signed certificate in certificate chain
This error occurs when the Elasticsearch service is unable to retrieve version information from nodes due to a self-signed certificate in the certificate chain.
To resolve this issue, you need to configure Elasticsearch to trust the self-signed certificate by adding it to Elasticsearch's truststore. You can do this by following these steps:
1. Locate the Elasticsearch truststore file on your system. On Linux systems, this is typically located at /etc/elasticsearch/truststore.jks.
2. Add the self-signed certificate to the truststore using the keytool utility. The command to do this is as follows:
```
keytool -import -file /path/to/certificate.crt -alias mycertificate -keystore /path/to/truststore.jks
```
Replace /path/to/certificate.crt with the path to the self-signed certificate file, and /path/to/truststore.jks with the path to the Elasticsearch truststore file.
3. Restart the Elasticsearch service to apply the changes.
After completing these steps, the Elasticsearch service should be able to retrieve version information from nodes without encountering the self-signed certificate error.

这个错误通常是由于 Elasticsearch 节点使用的证书是自签名证书,而不是由受信任的证书颁发机构(CA)颁发的证书所导致的。解决办法是在 Elasticsearch 客户端配置中添加一个选项,以允许使用自签名证书。具体来说,你需要在 Elasticsearch 客户端的配置中设置以下选项:
```python
from elasticsearch import Elasticsearch
es = Elasticsearch(
['localhost'],
scheme="https",
port=9200,
http_auth=('user', 'password'),
verify_certs=False,
ssl_show_warn=False
)
```
其中,`verify_certs=False` 表示不验证证书,而 `ssl_show_warn=False` 则表示不显示警告信息。请注意,这种方法并不安全,因为它允许使用不受信任的证书,因此应该仅在测试环境中使用。在生产环境中,应该使用由受信任的证书颁发机构颁发的证书来保护 Elasticsearch 节点。
