Ubuntu_jdk_jdk7_安装_.rpm.bin文件安装

Ubuntu11.04安装JDK7

第一步 下载

去下面的地址下载java7的开发包（或者去官方网站下载吧）

http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-i586.tar.gz

 

第二步 解压

sudo tar zxvf ./jdk-7-linux-i586.tar.gz  -C /usr/lib/jvm
cd /usr/lib/jvm
sudo mv jdk1.7.0/ java-7-sun

   

第三步 修改环境变量

vim ~/.bashrc

#加入以下内容

export JAVA_HOME=/usr/lib/jvm/java-7-sun
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

#保存后使之生效
source ~/.bashrc

 

第四步 配置默认程序

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-sun/bin/java 300
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-7-sun/bin/javac 300
sudo update-alternatives --config java
#如果你的系统中安装了其他的jdk，系统会提示出来，选择jdk7即可

 

最后 测试效果

minch@Minch-Ubuntu:/usr/lib/jvm$ java -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Server VM (build 21.0-b17, mixed mode)

 

 

切记根据自己的机器的版本是64位还是32位来选择下载相应的文件来安装！！！

Ubuntu最好下载jdk-6u33-linux-x64.bin，不要下载rpm的版本：jdk-6u33-linux-i586-rpm.bin

.rpm.bin文件安装

需要先用alien转化

 

.rpm.bin文件安装

#先解压并且放置在安装的目录

chmod u+x jdk-6u33-linux-x64.bin

./jdk-6u33-linux-x64.bin

mv ./jdk1.6.0_33 /usr/local/

#设置环境便利（同上）

 

 

切记根据自己的机器的版本是64位还是32位来选择下载相应的文件来安装！！！
