　　System prompts that:"wget: unable to resolve host address".

 
//Analysis
 　　Unable to resolve host address means the problem of DNS（Domain Name System）.
 
 //Solution
 　　To fix the problem, the configuration file "resolv.conf" should be  modified as follow steps:
             1. Get the root permission:      su -i
             2. Open the file with vi editor:      vi /etc/resolv.conf
             3. Press "i" into edit mode, and modify the content by:
                   nameserver 8.8.8.8 #google‘s DNS
