Set the CD to yum source tutorial

We all know that yum can be used only when connected to centos, and is limited by the network speed. In addition, RHEL needs to buy a red hat subscription account to install software and update the system online. If you use a local CD as the yum source, the speed will be faster and RHEL can also be used. 1. Insert a CD in the optical drive, or mount the iso file. 2. log on to the terminal as a root user. 3. run the following command to mount the CD: [root @ centos6 ~] #

1. Insert a CD in the optical drive or attach an iso file.

2. log on to the terminal as a root user

3. run the following command to mount the disc.

[root@centos6 ~]# mkdir /mnt/cdrom[root@centos6 ~]# mount -o ro /dev/cdrom /mnt/cdrom

4. create the text file server. repo under/etc/yum. repos. d.

[root@centos6 ~]# vim /etc/yum.repos.d/server.repo

Add the following content:

[server]name=serverbaseurl=file:///mnt/cdrom/Workstationenabled=1

The location of the baseurl depends on the location where the disk is mounted and the version released in linux.

5. test yum

[root@centos6 ~]#yum clean[root@centos6 ~]#yum list

You can see the software packages that can be installed.
