Question

所以我尝试使用以下命令启动elasticsearch：

systemctl start elasticsearch.service

我收到此错误：

Job for elasticsearch.service failed because a fatal signal was delivered to the control process.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

这是“ journalctl -xe”输出：

按照官方https://www.elastic.co/guide/en/elasticsearch/reference/current/targz.html安装说明使用tarball安装解决了该问题。

请确保您用来运行Elasticsearch进程的用户对正在写入Elasticsearch进程的文件系统具有写访问权。请参阅问题部分中的评论，以获取与此相关的更多信息和错误。
