ElasticSearch和Java环境变量 [英] ElasticSearch and Java environment variable

问题描述

对于Windows 7，我已经在32位和64位版本中安装了JDK。所有四个安装的版本为8，更新20。
http://www.oracle.com/technetwork/java/当我下载并解压缩弹性搜索，并运行/bin/service.bat或/ bin / elasticsearch时，javase / downloads / jdk8-downloads-2133151.html

.bat文件，我进入我的终端：

必须设置JAVA_HOME环境变量！
按任意键继续。 。

当我做，终端关闭。

我已经卸载并重新安装，但没有修复它。为什么环境变量不会设置？这是一个安装的东西，或者我实际上必须手动设置变量。它似乎如果它正确安装，它将自动设置变量...请帮助。感谢

我已经使用这个手动设置了JAVA_HOME环境变量。

https://confluence.atlassian.com/display/DOC/Setting+the+JAVA_HOME+Variable+in+Windows

我的路径是 C：\Progra〜1\Java\jdk1.8.0_20\jre

现在，当我运行service.bat，终端在打开时立即关闭。
当我运行elasticsearch.bat，终端打印一些行，一段时间后，它只停留在那里，我不能打字。

编辑：

我卸载了所有的java，只重新安装了JRE 64位，并将系统环境变量设置为 JAVA_HOME 和`C：\Progra〜1\Java\jre1.8.0_20

我发现有 CLASSPATH ，设置为一个32位较旧的Java版本。我应该删除该变量吗？

解决方案

步骤1

您可以验证 JAVA_HOME 设置为 C：\Progra〜1\Java\jdk1.8.0_20 ，

  C：\> echo％JAVA_HOME％
  

此外，验证 java 命令可用

  java -version

For Windows 7, I've installed JDK in both 32 and 64 bit versions. The versions are 8, update 20 for all four installations. http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

when I download and unzip elasticsearch, and run /bin/service.bat or /bin/elasticsearch.bat files, I get in my terminal:

JAVA_HOME environment variable must be set! Press any key to continue . . .

When I do, the terminal closes.

I've uninstalled and reinstalled, but that didn't fix it. Why wouldn't the environment varaible get set? Is it an installation thing, or do I actually have to manually set the variable. It just seems like if it installed correctly, it would set the variable automatically... Please help. Thanks

I've manually set the JAVA_HOME environment variable using this.

https://confluence.atlassian.com/display/DOC/Setting+the+JAVA_HOME+Variable+in+Windows

My path is C:\Progra~1\Java\jdk1.8.0_20\jre

Now, when I run service.bat, the terminal immediately closes upon opening. When I run elasticsearch.bat, the terminal prints some lines, and after a while, it just stays there, and I can't type anything.

EDIT:

I uninstalled all java, reinstalled only the JRE 64 bit, and set the system environment variable to JAVA_HOME and `C:\Progra~1\Java\jre1.8.0_20

I have discovered that there is CLASSPATH that's set to a 32bit, older java version. Should I delete that variable?

解决方案

STEP 1

Can you verify JAVA_HOME is set to C:\Progra~1\Java\jdk1.8.0_20,

C:\>echo %JAVA_HOME%

Also, verify java command is available,

 java -version

Reference

Check if JAVA_HOME is present in environment using batch script
