i 下载JRE(Java Runtime Environment) 。(http://java.sun.com/javase/downloads/index.jsp)

ii. [root@localhost ~]#mkdir /usr/local/java

iii. (将档案jre-1_5_0_09-linux-i586-rpm.bin下载到/usr/local/java目录下)

iv. (超级用户模式)
[root@localhost ~]#su

v. [root@localhost ~]#cd /usr/java

vi. (将您所下载的档的权限更改为可执行)
[root@localhost java]#chmod a+x jre-1_5_0_09-linux-i586-rpm.bin

vii. (启动安装过程)
[root@localhost java]#./jre-1_5_0_09-linux-i586-rpm.bin
(此时将显示二进制许可协议，按控格显示下一页，读完许可协议后，输入『yes』继续安装。此时会将解压缩，产生jre-1_5_0_9-linux-i586.rpm)

viii. (安装jre-1_5_0_9-linux-i586.rpm)
[root@localhost java]#rpm –ivh jre-1_5_0_9-linux-i586.rpm

(此时会将JRE装在/usr/java/jre1.5.0_09目录下)

ix. (设定环境变量，让Linux能找到JRE)
[root@localhost java]#vi /etc/profile
(将以下内容加入在档案后面)

1PATH=$PATH:/usr/java/jre1.5.0_09/bin
2export JAVA_HOME=/usr/java/jre1.5.0_09
3export CLASSPATH=$JAVA_HOME/lib:.

(存盘后，重新启动Linux)

x. (测试Java是否安装成功)
[root@localhost ~]#java –version
