Today, we continue to install the JDK to the ali cloud service, you have to see whether ali cloud is 32-bit or 64-bit, if it is 32-bit download 32-bit package, if it is 64-bit download 64-bit package
Mine is 64-bit. At first, I don't know how to distinguish 32/64-bit. X64 is 64-bit
Now I'll list the package's name. The jdk-7u25-linux-x64.rpm.x64 represents a 64-bit system.
First, download the JDK package. I'm now downloading the JDK -7u25-linux-x64.rpm package and then go to it via XFTP
