centos7默认最小化安装，所以很多的软件没有，然而系统自带的是国外的源，所以必须要更新国内的源，打开

选择centos7,下载的文件中有如下的内容

# CentOS-Base.repo
    #
    # The mirror system uses the connecting IP address of the client and the
    # update status of each mirror to pick mirrors that are updated to and
    # geographically close to the client.  You should use this for CentOS updates
    # unless you are manually picking other mirrors.
    #
    # If the mirrorlist= does not work for you, as a fall back you can try the 
    # remarked out baseurl= line instead.

在/etc/目录下创建CentOS-Base.repo这个文件（一般都有，但是我这里不知道为什么没有了），然后把前面网站上下载的文件中的内容黏贴过来，保存

yum clean all

yum makecache
