Question

我通过阅读此tutorial安装了预构建Elasticsearch 1.0.0版本。如果我开始弹性搜索，我收到以下错误消息，我应该尝试使用旧版本的ES或如何解决此问题吗？

Answer 1

首先必须停止正在运行的演示应用程序，该应用程序已绑定到8080.可以使用以下命令完成：

ctl_app stop

运行此命令后，您将能够在端口8080上启动elasticsearch。但是，建议不要将其用于生产环境。

Answer 2

我建议使用此盒式磁带安装ElasticSearch：https://github.com/ncdc/openshift-elasticsearch-cartridge

它将为您省去手动自定义配置的麻烦。

Answer 3

您尝试将ES分配给已经使用的端口8080。配置中的罪魁祸首是http.port: ${OPENSHIFT_DIY_PORT}。只需将port个配置保留在配置之外，或者将envvar分配给其他端口。 ES的默认端口为9200，http为9300。

在OpenShift上安装elasticsearch
