问题描述
我正在尝试在我的 CentOS 服务器上使用 jmap 命令，但它一直告诉我该命令即使我安装了JDK，也找不到。
I'm trying to use the jmap command on my CentOS server but it keeps telling me that the command was not found even though I have the JDK installed.
这是命令的输出 java -version ：
java version "1.7.0_25"
OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
如何解决此问题？
推荐答案
您应该能够在 java-1.8.0-openjdk-devel-debug jmap Redhat / Centos上的>，或 java-1.7.0-openjdk-devel-debug 或 java-1.6.0-openjdk-devel-debug 包。要安装它，请以root身份运行以下命令：
You should be able to find jmap in the java-1.8.0-openjdk-devel-debug, or java-1.7.0-openjdk-devel-debug, or java-1.6.0-openjdk-devel-debug packages on Redhat/Centos. To install it, run the following as root:
yum install java-1.8.0-openjdk-devel-debug
为了完整性，这里是检查哪些包包含jmap的命令：
For completeness, here's the command to check which packages include jmap:
yum whatprovides '*/jmap'
这里是示例输出：
