安裝

以jdk1.6.0_43為例

下載jdk-6u43-linux-x64.bin，http://www.oracle.com/technetwork/java/javase/downloads/index.html

增加可執行權限 chmod +x jdk-6u43-linux-x64.bin，

執行 ./jdk-6u43-linux-x64.bin 生成目錄jdk1.6.0_43

拷貝到/usr/share下，mv jdk1.6.0_43 /usr/share

另外，jdk-6u43-linux-x64.bin將所有文件解壓縮到當前目錄的jdk$verison_$update目錄，

jdk-6u43-linux-x64-rpm.bin解壓縮生成rpm包，用rpm -ivh命令安裝

配置環境變量

在/etc/profile下增加

				?

									# set java environment

									java_home=/usr/share/jdk1.6.0_43

									path=$java_home/bin:$path

									classpath=.:$java_home/lib/dt.jar:$java_home/lib/tools.jar

									export java_home

									export path

									export classpath

測試
