ElasticSearch 和 Java 环境变量 [英] ElasticSearch and Java environment variable
问题描述
对于 Windows 7，我已经安装了 32 位和 64 位版本的 JDK.所有四个安装的版本都是 8，更新 20.http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
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
当我下载并解压缩 elasticsearch 并运行/bin/service.bat 或/bin/elasticsearch.bat 文件时，我进入了我的终端:
when I download and unzip elasticsearch, and run /bin/service.bat or /bin/elasticsearch.bat files, I get in my terminal:
JAVA_HOME 环境变量必须设置！按任意键继续 ...
当我这样做时，终端关闭.
When I do, the terminal closes.
我已经卸载并重新安装，但这并没有解决它.为什么不设置环境变量?这是安装问题，还是我实际上必须手动设置变量.看起来如果它安装正确，它会自动设置变量......请帮忙.谢谢
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
我已经使用它手动设置了 JAVA_HOME 环境变量.
I've manually set the JAVA_HOME environment variable using this.
https://confluence.atlassian.com/display/DOC/Setting+the+JAVA_HOME+变量+in+Windows
我的路径是C:Progra~1Javajdk1.8.0_20jre
现在，当我运行 service.bat 时，终端在打开时立即关闭.当我运行 elasticsearch.bat 时，终端会打印一些行，一段时间后，它就停留在那里，我无法输入任何内容.
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.
我卸载了所有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~1Javajre1.8.0_20
I uninstalled all java, reinstalled only the JRE 64 bit, and set the system environment variable to JAVA_HOME and `C:Progra~1Javajre1.8.0_20
我发现有 CLASSPATH 设置为 32 位，较旧的 Java 版本.我应该删除那个变量吗?
I have discovered that there is CLASSPATH that's set to a 32bit, older java version. Should I delete that variable?
