在OpenShift上安裝elasticsearch

Question

我通過閱讀tutorial安裝了預編譯版本Elasticsearch 1.0.0版本。如果我啓動elasticsearch，我收到以下錯誤消息：我應該嘗試舊版ES還是如何解決此問題？

Answer 1

您嘗試將ES分配給端口8080，該端口已被佔用。從那裏配置的罪魁禍首是http.port: ${OPENSHIFT_DIY_PORT}。只需將兩個port配置保留在配置之外或將envvar分配給其他某個端口。對於ES的默認端口是9200 HTTP和9300

Answer 2

您必須首先停止正在運行的演示應用程序，它已經綁定到8080這可以使用下面的命令來完成：

ctl_app stop 

運行後該命令將能夠在端口8080上啓動elasticsearch。但是，這不建議在生產環境中使用。

Answer 3

我會建議與盒安裝ElasticSearch：https://github.com/ncdc/openshift-elasticsearch-cartridge

這將節省您手動自定義配置的頭痛。
