错误提示如下
[root@newings yum.repos.d]# yum -c /etc/yum.conf --installroot=/usr/local/wget install wget -y Loaded plugins: fastestmirror Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com http://mirrors.aliyun.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Trying other mirror. http://mirrors.aliyuncs.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 12] Timeout on http://mirrors.aliyuncs.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: (28, ‘connect() timed out!‘) Trying other mirror. http://mirrors.cloud.aliyuncs.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - "Couldn‘t resolve host ‘mirrors.cloud.aliyuncs.com‘" Trying other mirror.

解释下两个参数
-c /etc/yum.com #指定Yum配置文件地址
--installroot=/usr/local/wget #指定所安装软件的路径
该错误是由于$releasever和$basearch这两个变量中任何一个无法识别都会出现上面的错误，所以在配置yum源的时候首先要确认这两个变量是否存在。
如果变量不存在就用数字6和i386/x86_64代替。
我的配置如下
