macos - ElasticSearch 5.6 无法在 Mac OS 上启动

Question

使用 Brew 安装 ElasticSearch 5.6 服务器后，我无法在 Mac 上启动它。得到这个错误:

$ /usr/local/opt/elasticsearch@5.6/bin/elasticsearch
Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource BufferedChecksumIndexInput(SimpleFSIndexInput(path="/usr/local/etc/elasticsearch/elasticsearch.keystore"))): 3 (needs to be between 1 and 2)

Refer to the log for complete error details.

由于它不是最新版本的 ElasticSearch，我想它安装了一些不兼容的包版本，但不确定具体是什么包。

任何人都可以帮助它工作吗？

我刚刚遇到了同样的问题，重新生成 keystore 为我解决了这个问题。以下是我采取的步骤:

备份现有的 keystore :

cd /usr/local/etc/elasticsearch/
mv elasticsearch.keystore elasticsearch.keystore.old

生成新的 keystore :

cd /usr/local/Cellar/elasticsearch@5.6/5.6.15/libexec/bin/
elasticsearch-keystore create
