ElasticsearchException 绑定(bind)服务失败错误

Question

我真的想开始使用 Elasticsearch 来连接 opencart。
我已经设置了network.host:0.0.0.0(也尝试了我的本地IP)，http.port:9200，并赋予我的新帐户执行权限。我使用centOs6，Java 1.8，不使用root 帐户。
我想在我的服务器上使用 elasticsearch，但我有一些问题。

我的错误日志是

我已经通过 tar.gz 安装了。
我改变了一些 config/elasticsearch.yml
我没有改变其他任何东西
有人知道这个错误吗？请帮我。

您需要确保主机上的目录归 1000:1000 所有。运行以下命令。

sudo chown 1000:1000 <directory you wish to mount>
