Spring2.5学习笔记1-控制反转-DI容器泛型访问

1、删除rhel自带的yum源

rpm -aq | grep yum|xargs rpm -e --nodeps

2、下载新的yum安装包

wget http://mirrors.163.com/CentOS/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
3、安装yum包，注意的是标红的必须一起装，有依赖关系

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-69.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

4、更改成163的yum源

cd /etc/yum.repos.d/

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
ls
CentOS6-Base-163.repo

把文件里面的$releasever全部替换为版本号，即6

sed -i 's#$releasever#6#g' CentOS6-Base-163.repo

5、清除yum缓存

yum clean all

yum makecache
