cd /etc/yum.repos.d/

3. Modify the file vi, add the image in media to a new yum source, and enable

vim rhel-source.repo

4. Run the yum list command to check whether the yum source is successfully added. <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4KCjxwPjUueXVt1LTF5NbDs8m5prrzo6y9 + NDQsLLXsDwvcD4KCjxwcmUgY2xhc3M9 "brush: java;"> yum –y install gcc*yum –y install telnet*
