在网上找了不少东西，有的就是贴了个repo的文件，还是自己整理下，软件源设置好了，才可以快速的安装软件呀！
现在根据我们的国情(china)设置我们的文件，我们用的比较多的就是中科大的源
修改repo文件，总结来说就是注释mirrorlist,添加baseurl，如下是我的：
测试一下：
yum repolist all #列出现在yum server所使用的容器有哪些
如果有问题可以使用清除功能：
yum clean all #所有容器的数据删除
更新一下全系统：
yum -y update #系统整体升级
查看所有的内核
rpm -q kernel #查询存在的内核版本
删除新的内核（应该要重启进入新的内核版本再删吧，呵呵，没有试过当前版本删除！）
rpm -e kernel-2.6.32-71.29.1.el6.i686 #删除你查询到的旧内核，复制粘贴就比较方便了！
插件是个好东西，可以让我们给应用程序扩展功能，很多插件的安装也比较简单，而且可以有插件扩展的程序，功能才可以更加完善。
安装的方法有一些，比如可以在程序中选择相应的功能选项，或者直接下载相应的文件放到对应的文件。如foobar的插件就可以在官网：http://www.foobar2000.org/components/index.html，然后把*.dll文件放到安装目录下的comments文件夹下，重启就可以了。
