如何刪除elasticsearch？

Question

我正在嘗試使用elasticsearch和Kibana進行logstash工作。我擁有所有最新版本，但在遇到一些問題後，我意識到我需要安裝較早版本的彈性搜索（即0.20.6），以便它能夠與最新版本的logstash一起正常工作。所以，我下載了舊版本，做了舊版本（v.0.90.x）的0​​，並安裝了新版本（v.0.20.6）。我試圖啓動它。它開始，但然後給我重複錯誤，如：

正如你所看到的，它仍然試圖尋找v.0.90.x安裝。我localhost:9200顯示以下的輸出：

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

如何解決這個使用v.0.20.6？

Answer 1

看起來你仍然有0.90跑步。您需要關閉它，然後才能切換到0.20。最簡單的方法是通過運行

curl -XPOST 10.1.10.52:9200/_shutdown 

如果這不起作用，請找到elasticsearch正在運行的java進程並殺死它。

在0.90關閉後，您可能需要重新清理目錄。

Answer 2

 In windows stop all the services. I mean Elastic search ,Kibana ,Logstash and beats if any. 

     I installed them following http://robwillis.info/2016/05/installing-elasticsearch-logstash-and-kibana-elk-on-windows-server-2012-r2/ . Here he has explained the instaling steps very beautifully. Thanks A Lot. 
I downloaded the zip and extracted them in a single folder as the below image

Installation steps are as below. 

PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\elasticsearch-5.6.3\bin\elasticsearch-service install" 
Installing service  : "elasticsearch-service-x64" 
Using JAVA_HOME (64-bit): "C:\Program Files\Java\jdk1.8.0_65" 
The service 'elasticsearch-service-x64' has been installed. 

PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\elasticsearch-5.6.3\bin\elasticsearch-service manager" 
Successfully started service manager for 'elasticsearch-service-x64'. 

PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\nssm-2.24\win64\nssm install Logstash" 
Service "Logstash" installed successfully! 
PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\nssm-2.24\win64\nssm install kibana" 
Service "kibana" installed successfully! 
PS C:\windows\system32> PowerShell.exe -ExecutionPolicy UnRestricted -File C:\ELKStack\filebeat-5.6.3-windows-x86_64\.\i 
nstall-service-filebeat.ps1 

Security Warning 
Run only scripts that you trust. While scripts from the Internet can be useful, this script can potentially harm your 
computer. Do you want to run C:\ELKStack\filebeat-5.6.3-windows-x86_64\install-service-filebeat.ps1? 
[D] Do not run [R] Run once [S] Suspend [?] Help (default is "D"): R

     Now to unistal I used the following method. 

    Open windows powershell 


     PS C:\windows\system32> PowerShell.exe -ExecutionPolicy UnRestricted -File C:\ELKStack\filebeat-5.6.3-windows-x86_64\un 
     install-service-filebeat.ps1

     PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\nssm-2.24\win64\nssm remove Kibana" 
     Service "Kibana" removed successfully! 

     PS C:\windows\system32> Invoke-Expression -command "C:\ELKStack\nssm-2.24\win64\nssm remove logstash" 
     Service "Logstash" removed successfully!
