Question

我正在尝试为greylog安装elasticsearch，我已经安装了java并且在我的elasticSearch.yml文件中我更改了这些：

cluster.name:graylog
node.name: "node-1"
network.host: 0.0.0.0
network.bind_host: localhost
network.publish_host: 0.0.0.0
script.inline: false
script.indexed: false
script.file: false

所有其他人都有评论。但是当我运行命令时

curl -X GET 'http://localhost:9200'

我收到了这个错误：

curl: (7) Failed connect to localhost:9200; Connection refused

可能是什么问题？

我明白了：

看起来你无法写入数据目录，因此节点无法启动。

你是否有机会在Docker中运行它并且没有设置正确的权限？这是导致此错误的最常见原因。
