-bash: /usr/bin/java: No such file or directory

卸载完成，下面执行安装过程。

我们需要找到JDK 1.6的下载链接：http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html

出处：http://stackoverflow.com/questions/3731133/where-can-i-download-jdk-1-6u20-64-bit

选择Java SE Development Kit 6u45 版本，我们选择第一个下载包：

jdk-6u45-linux-i586-rpm.bin

赋予可执行权限

[root@localhost Desktop]# ls

jdk-6u45-linux-i586-rpm.bin

[root@localhost Desktop]# chmod +x jdk-6u45-linux-i586-rpm.bin
