Method 2: Use the local iso file when you cannot access the Internet

 

a. ftp upload the iso installation file to /usr/local/src

 

b. Create a new /media/CentOS, mount the iso file to /media/CentOS

 

 mount -t iso9660 -o loop /usr/local/src/CentOS-7-x86_64-DVD-1511.iso /media/CentOS

 

c. Set the system image file to be automatically mounted at startup

 

vim /etc/fstab add

/usr/local/src/CentOS-7.0-1406-x86_64-DVD.iso /media/ CentOS / iso9660 defaults,ro,loop 0 0

:x #save and exit

mount -l

 

d. Back up the /etc/yum.repos.d/CentOS-Base.repo file and create a new CentOS-Base.repo file

 [root@localhost yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.bak

 

 [root@localhost yum.repos.d]# vi CentOS-Base.repo

 

 [centos7]  

 name=CentOS-$releasever - centos7  

 baseurl = file: /// media/CentOS  

 gpgcheck=0  

 enabled=1

 [root@localhost yum.repos.d]# yum clean all

 [root@localhost yum.repos.d]# yum install gcc
