No,it should be in in Libfolder
不，它应该在Lib文件夹中
c:\jdkx.x.x\lib
Files used by the development tools. These include tools.jar, which contains non-core classes for support of the tools and utilities in the JDK. Also includes dt.jar, the DesignTime archive of BeanInfo files that tell interactive development environments (IDE's) how to display the Java components and how to let the developer customize them for an application.
c:\jdkx.xx\lib

On Linux, you can use locate tools.jarto find where the file is.
在 Linux 上，您可以使用locate tools.jar来查找文件所在的位置。
Typically, it should be in the lib/ directory of your jvm. On Ubuntu/Debian, it is located in directory /usr/lib/jvm/java-xxxxx/lib/tools.jar.
通常，它应该在您的 jvm 的 lib/ 目录中。在 Ubuntu/Debian 上，它位于目录/usr/lib/jvm/java-xxxxx/lib/tools.jar.
For example, with openjdk 7, on amd64, I'll find it under /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar.
例如，对于 openjdk 7，在 amd64 上，我会在 /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar 下找到它。
I have no installation to check it, but I think that the directory structure is the same under CentOS (cf. https://serverfault.com/questions/50883/what-is-the-value-of-java-home-for-centos)
我没有安装来检查它，但我认为CentOS下的目录结构是相同的（参见https://serverfault.com/questions/50883/what-is-the-value-of-java-home-for -centos)

Not sure what rpm you used, but if you install from yum repo, you should install java-1.7.0-openjdk-develin addition to java-1.7.0-openjdk.
不确定您使用的是什么 rpm，但如果您从 yum 存储库安装java-1.7.0-openjdk-devel，除了java-1.7.0-openjdk.
Then you will find tools.jarin /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.xx.x86_64/libdirectory.
然后你会tools.jar在/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.xx.x86_64/lib目录中找到。

我的情况是，tools.jar 文件只有在安装 java-1.7.0-openjdk-devel 后才会生成。
sudo yum install java-1.7.0-openjdk-devel
须藤 yum 安装 java-1.7.0-openjdk-devel
