如何删除elasticsearch？

Question

我正在尝试使用elasticsearch和Kibana进行logstash.我有所有最新版本,但在遇到一些问题之后,我意识到我需要安装一个旧版本,即0.20.6的elasticsearch,以便它能够与最新版本的logstash一起正常工作.因此,我下载了旧版本,执行了旧版本rm -rf(v.0.90.x)并安装了新版本(v.0.20.6).我试着启动它.它开始,但然后给我重复错误,如:

如您所见,它仍在尝试查找v.0.90.x安装.我localhost:9200显示以下输出:

{
  "ok" : true,
  "status" : 200,
  "name" : "Blob",
  "version" : {
    "number" : "0.90.2",
    "snapshot_build" : false,
    "lucene_version" : "4.3.1"
  },
  "tagline" : "You Know, for Search"
}

如何使用v.0.20.6解决此问题？

Answer 1

看起来你仍然有0.90跑步.您需要关闭它才能切换到0.20.最简单的方法是运行

curl -XPOST 10.1.10.52:9200/_shutdown

如果这不起作用,找到运行elasticsearch的java进程并将其终止.

0.90关闭后,您可能需要再次清理目录.
