# 报错, 依赖包的版本不符：
rpm >= 0:4.11.3-22 is needed by yum-3.4.3-154.el7.centos.noarch
- 解决方法: 将所依赖的python-urlgrabber和rpm包升级

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-8.el7.noarch.rpm

# 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.
