ElasticSearch 5.6无法在Mac OS上启动

Posted 2021-03-27

用Brew安装后，我无法在Mac上启动ElasticSearch 5.6服务器。得到此错误：

$ /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)

由于它不是ElasticSearch的最新版本，我认为它安装了一些不兼容的软件包版本，但不确定是哪个软件包。

任何人都可以帮助它的工作吗？

答案

我刚才有同样的问题，重新生成密钥库为我解决了问题。以下是我采取的步骤：

备份现有密钥库：

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

生成新的密钥库：

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

另一答案

服务器很可能正在尝试读取较新的索引（org.apache.lucene.index.IndexFormatTooNewException）。

最有可能的唯一方法是完全摆脱它：

sudo rm -rf  /usr/local/var/lib/elasticsearch

请仔细检查索引并确保您不再需要旧的6. *索引，因为您显然会丢失它。
