# 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.

将上面脚本保持为setproxy，然后执行,注意，如果当前环境下已经有了http_proxy等变量。则需要我们手动reset

chmod u+x setproxy
source setproxy http://10.100.100.136:4411
