1)下载对应CentOS版本的jdk：这里我下载的是 jdk-7u79-linux-x64.tar.gz。下载该jdk到本地，并上传到你的CentOS 6.4系统的opt临时目录下, 或是直接在虚拟机上网下载,默认的是（Downloads）

2）新建一个jdk的安装目录，在/usr/local/下新建了java目录，

**命令:mkdir -p /usr/local/java**

再把 jdk-7u79-linux-x64.tar.gz压缩包从Downloads目录下复制到/usr/local/java目录下，命令如下：

**命令: cp jdk-7u79-linux-x64.tar.gz ../usr/local/java**

3)解压缩刚才下载的： jdk-7u79-linux-x64.tar.gz包，

**命令:tar xvf jdk-7u79-linux-x64.tar.gz**

4)解压完之后，进入root用户

**\[root@localhost /\]\# cd /etc  
\[root@localhost etc\]\# vi profile**

**如图所示：**

4) 在profile文件的末尾加入如下命令：

**export JAVA\_HOME=/usr/local/java/jdk1.7.0\_79  
export JRE\_HOME=/usr/local/java/jdk1.7.0\_79/jre  
export PATH=$PATH:/usr/local/java/jdk1.7.0\_79/bin  
export CLASSPATH=./:/usr/local/java/jdk1.7.0\_79/lib:/usr/local/java/jdk1.7.0\_79/jre/lib**

5) 输入:wq保存并退出, 测试jdk是否安装成功
