无法启动 Elasticsearch。打开日志文件“/gc.log”时出错：权限被拒绝

Question

亲爱的 StackOverflow 社区，

在安装 Kibana 插件之前，我运行 Kibana/Elasticsearch 没有任何问题。然后服务失败，我注意到问题是 Elasticsearch 停止了。我尝试了多种方法来修复它，然后甚至重新安装了所有方法。但问题仍然是避免启动 Elasticsearch，即使是全新安装。

使用 apt install 在 Debian 9 上安装。

systemctl start elasticsearch.service

结果：

Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]

[0.000s][error][logging] Error opening log file '/gc.log': Permission denied

提到的 gc.log 文件不在该文件夹中。权限是：

drwxr-s--- 2 elasticsearch elasticsearch 4096 Jan 15 13:20 elasticsearch

我创建了该文件并使用了权限，直到获得以下权限：

-rwxrwxrwx 1 root elasticsearch 0 Feb 7 15:19 gc.log

...甚至改变了所有权：

-rwxrwxrwx 1 root root 0 Feb 7 15:19 gc.log

但没有成功，我仍然遇到同样的问题。

谢谢
