#
# 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.

3) Since the default $releasever is set to "7server" , I need to change this to "7", or yum cannot find corresponding folder in mirror site

vi /etc/yum/vars/releasever    , input 7 , then save the file

4) yum install -y /home/<UserName>/Download/microsoft-edge-dev-88.0.685.3-1.x86_64.rpm
