Question

我真的想开始对opencart进行Elasticsearch。我已经设置了network.host：0.0.0.0（也尝试使用我的本地IP），http.port：9200，并将执行权限授予了我的新帐户。我使用centOs6，Java 1.8，并且不使用root帐户。我想在服务器上使用elasticsearch，但是我遇到了一些问题。

我的错误日志是

Answer 1

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>

Source

Answer 2

在我的变体中，麻烦在于数据目录的权限。数据目录不是默认目录，而是更改为/ elk-data /

为解决此问题，我进行了“ chmod -R elasticsearch：wheel / elk-data ”

Answer 3

请检查以下内容：

您是否在文件系统中创建了/var/data/elasticsearch和/var/logs/elasticsearch目录？
您是否已将以上目录设置为在您的用户权限下可写？

更新：

在Github中阅读elasticsearch的源代码。 Link Here 代码尝试访问/etc/system-release时似乎出现了一些问题。您可能要看一下该文件。它还提到它是fallback for older Red Hat-like OS。因此，如果可能，您可能希望使用其他操作系统。
