The difference JAVA JDK, JRE, JVM's, Linux in the end you want to install and what version of the JDK RPM?

When installing Linux application infrastructure environment, always install a fixed version of the JDK, no one knows why. I also did not learn JAVA.

To dissolve doubts, keep Baidu, only now know, the original Linux installation environment for JAVA JDK configuration is to configure the application according to an edited version of JAVA.

JDK: JAVA Development Kit, JAVA development tool kit (developers use)

JRE: JAVA Runtime environment, JAVA runtime environment (ordinary users)

JVM: JAVA Virtual Mechine, JAVA virtual machine (ordinary users)

However, installing an RPM RPM, corresponding to such RPM according to the GCC CentOS version.
