在CentOS系统中，可以直接通过yum来安装组件，但系统默认的yum源速度往往不尽人意，都连接海外的，为了在国内达到快速安装的目的，就要需要修改yum源，可以使用

http://mirrors.163.com/   http://mirrors.sohu.com 这2个国内源。

执行以下命令就可以了

cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.bak
wget http://mirrors.163.com/.help/CentOS-Base-163.repo

或
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

运行yum makecache生成缓存

搞定。

yum 在启动 fastestmirror 插件时出错，是 yum 的一个 bug（http://yum.baseurl.org/ticket/70）。如果停掉 mysqld，yum 一切工作正常。临时解决办法是 yum update 时禁止启动 fastestmirror 插件。

yum –disableplugin=fastestmirror update

deepvps晚上Google好久没有结果。后来问了猫哥，猫哥果然高人，三言两语就给解决了。现在简单记录如下，方便后面出现问题的同学查看。

在SSH里面依次输入下面的命令：

1，下载最新的yum-3.2.28.tar.gz并解压

wget http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz
tar xvf yum-3.2.28.tar.gz


2，进入目录，运行安装

cd yum-3.2.28
yummain.py install yum

结果提示错误： CRITICAL:yum.cli:Config Error: Error accessing file for config file:///etc/

后来经猫哥提醒，原来是缺少配置文件。在etc目录下面新建yum.conf文件，然后再次运行 yummain.py install yum，顺利完成安装。

3，最后更新系统，全部搞定，收工。^_^

yum check-update
yum update
yum clean all
