yum makecache可能會出現以下
錯誤:發現仍然是：404 Not Found
我們嘗試進入http://mirrors .163.com/centos...Loaded plugins: refresh-packagekit, security http://mirrors.163.com/centos/6Server/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 -"The requested URL returned error: 404 Not Found" Trying other mirror.

這時我們進入http://mirrors.163.com/centos/發現：目錄下有6 6.0-6.8目錄，並沒有6Server目錄。猜測$releasever被錯誤地編譯為：6Server;正確情況下應為6.4。 （我的為CentOs6.4）
