elasticsearch配置xpack集群间加密认证时报错：-Toy模板网

这篇具有很好参考价值的文章主要介绍了elasticsearch配置xpack集群间加密认证时报错：。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

通过证书配置集群间节点通信认证：

bin/elasticsearch -E node.name=node1 -E cluster.name=geektime -E path.data=node1_data -E http.port=9200 -E xpack.security.enabled=true -E xpack.security.transport.ssl.enabled=true -E xpack.security.transport.ssl.verification_mode=certificate -E xpack.security.transport.ssl.keystore.path=certs/elastic-certificates.p12 -E xpack.security.transport.ssl.truststore.path=/user/share/elasticsearch/certs/elastic-certificates.p12

各种尝试：授权文件777、把文件放在config/certs下、放在/opt/elaticsearch/certs下，都想不通，然后猜测可能是路径问题，于是不写绝对路径，指定相对路径，看看es从那个目录下获取，改了之后包如下错误，发现是从/etc/elasticsearch/certs下读取：
