Done.

naxsu@ubuntu:/usr/local/jdk1.6.0_24$ vim /etc/profile

The program 'vim' can be found in the following packages:

 * vim

 * vim-gnome

 * vim-tiny

 * vim-athena

 * vim-gtk

 * vim-nox

Try: sudo apt-get install <selected package>

naxsu@ubuntu:/usr/local/jdk1.6.0_24$ sudo apt-get install vim

naxsu@ubuntu:/usr/local$ sudo vim /etc/profile

加入以下代碼：

#set java environment

export JAVA_HOME= /usr/local/jdk1.6.0_24

export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin

下面才有效

export JAVA_HOME=/usr/local/jdk1.6.0_24

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH

那如何將/etc/profile的設置在su root也能生效呢？

naxsu@ubuntu:~$ su - root

Password:

“-”不能省略，它是–login的編寫。

讓當前配置立即生效

root@ubuntu:~# source /etc/profile

測試安裝是否成功

root@ubuntu:~# echo $JAVA_HOME

/usr/local/jdk1.6.0_24

root@ubuntu:~# echo $PATH

/usr/local/jdk1.6.0_24/bin:/bin:/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/bin

root@ubuntu:~# echo $CLASSPATH

.:/usr/local/jdk1.6.0_24/lib/dt.jar:/usr/local/jdk1.6.0_24/lib/tools.jar

root@ubuntu:~# java -version

java version "1.6.0_24"

Java(TM) SE Runtime Environment (build 1.6.0_24-b07)

Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode, sharing)

以上提示說明安裝成功。
