1.下载jdk1.7.0_67并且解压,放知道/usr/local/lib/jvm目录下
tar zxvf jdk1.7.0_67.tar.gz
sudo mv jdk1.7.0_67 /usr/local/lib/jvm
2.编辑~/.bashrc文件,添加如下内容。
JAVA_HOME后的内容为你自定义的JDK存放目录
export JAVA_HOME=/usr/local/lib/jvm/jdk1.7.0_67
export JRE_HOME=${JAVA_HOME}/jre
exportCLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
3.设置JDK默认版本
sudo update-alternatives --install "/usr/bin/java/" "java" "/usr/local/lib/jvm/jdk1.7.0_67/bin/java" 300
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/lib/jvm/jdk1.7.0_67/bin/javac" 300
sudo update-alternatives --install "/usr/bin/jar" "jar" "/usr/local/lib/jvm/jdk1.7.0_67/bin/jar" 300
sudo update-alternatives --install "/usr/bin/javah" "javah" "/usr/local/lib/jvm/jdk1.7.0_67/bin/javah" 300
sudo update-alternatives --install "/usr/bin/javap" "javap" "/usr/local/lib/jvm/jdk1.7.0_67/bin/javap" 300
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/lib/jvm/jdk1.7.0_67/bin/javaws" 300
sudo update-alternatives --set java /usr/local/lib/jvm/jdk1.7.0_67/bin/java
sudo update-alternatives --set javac /usr/local/lib/jvm/jdk1.7.0_67/bin/javac
sudo update-alternatives --set jar /usr/local/lib/jvm/jdk1.7.0_67/bin/jar
sudo update-alternatives --set javah /usr/local/lib/jvm/jdk1.7.0_67/bin/javah
sudo update-alternatives --set javap /usr/local/lib/jvm/jdk1.7.0_67/bin/javap
sudo update-alternatives --set javaws /usr/local/lib/jvm/jdk1.7.0_67/bin/javaws
4.检查
java -version
mik3y@mac:~$ java -version
java version "1.7.0_67"
