yum source file

 
 an introduction 

 
During the installation process, the rpm package dependency is too strong.
  

 
If all rpm packages are installed manually, it is more difficult to use rpm packages.
  

 
The advantage of yum online installation is that all software packages are placed on the official server, and when yum online installation is performed, the dependency problem can be automatically resolved.
  

 
Redhat's yum online installation requires payment, but centos does not.
  

 
 Two yum source files 

 
 The three CentOS7-Base-163.repo image files are as follows 

 
  [root@localhost yum.repos.d]# cat CentOS7-Base-163.repo
  

 
  # 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.
