Core installation and configuration of CentOS-7.0

Our CentOS-7.0 after the core installation, very happy, but not wait for the strength of the past to find the problem, how can not use yum? How can I not use ifconfig? What about pvcreate ?...... After that, you may start to scold me for being confused. Why can't so many basic commands be used? How can this problem be solved by the core installation written by this person.

I am wrong. Don't worry. The following text will help you solve this problem.

When we install files according to the/root/anaconda-ks.cfg this answer file (answer files do not understand their own Baidu) installed, cat view it

We found that core has no base installed in the system by default. The basic commands we need are packaged in the base. Now that the problem is found, we will start to install the base.

Enter the following command on the bash Interface

[[Email protected] yum. repos. d] # vi CentOS-dvd.repo [centos-DVD] Name = centosbaseurl = file: // MNT/Disk/enabled = 1 gpgcheck = 0: X [[email protected] yum. repos. d] # lsCentOS-Base.repo.bak CentOS-dvd.repo CentOS-Vault.repo.bakCentOS-Debuginfo.repo.bak CentOS-Sources.repo.bak # To facilitate our Yum. repos. d to repo files are changed to the Bak suffix, after the new add CentOS-dvd.repo files and set the relevant path of the other four files can be Baidu

After modification, enter the following command.

# Yum groupinstall base # The following will show 172 packages to be installed. Just run y.

Show complete!

Yum, ifconfig, pvcreate, and other commands can be used normally.
