Centos安装JDK与Tomcat

Centos安装JDK
1、  下载JDK
#wget http://download.oracle.com/otn-pub/java/jdk/7u21-b11/jdk-7u21-linux-x64.tar.gz?AuthParam=1366341912_31221476932c2f38def67f7e46f2e281 解压： tar –vxzf
2、  由于是已经编译好的文件，可以直接使用。把解压后的文件移动到/usr/local/路径下，并重命名为jdk
#mv ./jdk1.7.0_21  /usr/local/jdk
3、  设置Java运行环境变量，包括JRE与JAVA工具
#vim /etc/profile

#JAVA_HOMEEnvironment
export  JAVA_HOME=/usr/local/jdk
export  CLASSPATH=${JAVA_HOME}/lib:${JAVA_HOME}/jre/lib
export  PATH=${JAVA_HOME}/bin:${PATH}

#source/etc/profile 
4、  测试java与javac是否可用
#javav -version
#javac -version
