ubuntu10.10 安装 sun jdk

参考ubuntu论坛上的2篇文章搞定

1.下载 sun jdk， 我下载的是 jdk-6u24-linux-i586.bin

2.设定可执行权限

sudo chmod +x jdk-6u24-linux-i586.bin

3.执行安装

./jdk-6u24-linux-i586.bin

4.配置环境

sudo vim /etc/environment

添加如下行

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java/jdk1.6.0_24/bin"

CLASSPATH=".:/usr/lib/jvm/java/jdk1.6.0_24/lib"

JAVA_HOME="/usr/lib/jvm/java/jdk1.6.0_24"

5.设定默认jdk

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java/jdk1.6.0_24/bin/java 300

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java/jdk1.6.0_24/bin/javac 300

/usr/lib/jvm/java是我安装(解压)jdk的路径，此处替换为你自己的路径

6.将jvm加入选单

sudo update-alternatives --config java

7.大功告成，测试一下

java -version

在firefox中启用jvm

cd /usr/lib/mozilla/plugins/

sudo ln -s /usr/lib/jvm/java/jdk1.6.0_24/jre/lib/i386/libnpjp2.so
