Install jdk with rpm under linux

1. Download the rpm installation package of jdk, here is an example of jdk-6u21-linux-i586-rpm.bin

Download address: http://www.oracle.com/technetwork/java/javase/downloads/index.html

 

2. Move jdk-6u21-linux-i586-rpm.bin to the appropriate installation directory, and do not install the software in the /home path, which will easily involve the access rights of different users, so the maintenance of the program is quite Adverse. This will move the installation package to the /opt directory
