redhat 安装openjdk更新源

佳美6370

　　redhat的yum命令是需要钱的，所以这边用了CentOS的源来实现redhat的yum功能

　　
　　首先检查一下yum是否安装，默认情况都是安装的
　　输入以下命令
　　rpm -qa|greip yum
　　出现，代表已安装成功
　　yum-utils-1.1.30-14.el6.noarch
　　yum-rhn-plugin-0.9.1-43.el6.noarch
　　PackageKit-yum-0.5.8-21.el6.i686
　　yum-metadata-parser-1.1.2-16.el6.i686
　　yum-3.2.29-40.el6.noarch
　　yum-plugin-security-1.1.30-14.el6.noarch
　　
　　这里使用上海交大的CenOS的源来更新
　　创建文件
　　vi /etc/yum.repos.d/CentOS-Base.repo
　　输入一下内容
