先安装JDK
下载jdk：
mv jdk-7u21-linux-x64.tar.gz\?AuthParam\=1366529379_f7fe2af81268eee41771542b3191968c jdk-7u21-linux-x64.tar.gz
tar -xf jdk-7u21-linux-x64.tar.gz
设置PATH，比如我的～/.bash_profile:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
JAVA_HOME= HOME/software/jdk1.7.021CLASSPATH=.:JAVA_HOME/lib/tools.jar
PATH= PATH:HOME/bin:$JAVA_HOME/bin
export JAVA_HOME CLASSPATH PATH
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
JAVA_HOME= HOME/software/jdk1.7.021CLASSPATH=.:JAVA_HOME/lib/tools.jar
PATH= PATH:HOME/bin:$JAVA_HOME/bin
export JAVA_HOME CLASSPATH PATH
测试是否安装成功：
echo $JAVA_HOME
echo $PATH
