RPM Package Series

Root user

jdk1.6 version of RPM package: Jdk-6u45-linux-x64-rpm.bin

After execution, look again at the packages that will generate many sun-java-* RPM packages and jdk-6u45-linux-amd64.rpm.

We can use the command to see that these packages are already installed in the system.

In this process, the RPM package is automatically installed, the variable path does not need to be set up, the installation is finished, directly view the version.
