elasticsearch - Elasticsearch安装冲突

Question

我正在尝试在本地计算机上安装Elasticsearch。我已经下载了Elasticsearch并尝试按照documentation进行设置
但是，当我尝试Run bin/elasticsearch时，它显示日志的权限错误。然后我尝试将其作为sudo bin/elasticsearch运行，然后显示以下错误

[2017-11-20T12:08:40,340][WARN ][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main]

需要说明来解决此问题，谢谢

您应该向logs目录授予当前用户的权限(drwxrwxr-x)，然后通过bin/elasticsearch启动es(不要以root用户身份启动!)。
