Linux (ubuntu14.04) yum source installation, ubuntu14.04yum

An error occurred while installing the test environment. The file or folder does not exist in/etc/yum/repos. d and the yum source cannot be updated.

Solution:

(1) configure the network yum source)

1. First, create a yum. repo file in the/etc/yum/repos. d/directory (the name can also be self-prepared, and the suffix is. repo.

Vim/etc/yum. repos. d/yum. repo

2. open the file and add the following content (no need to add ):

[Server]

Name = Server... name of the Server

Baseurl = the file address of your yum source address... yum Library

Enable = 1... apply this server

Gpgcheck = 0 ...... disable verification.

Here we recommend an address: http://mirrors.ustc.edu.cn/centos/5/updates/?basearch/, that is

[Server]

Name = Server... name of the Server

Baseurl = http://mirrors.ustc.edu.cn/centos/5/updates/?basearch/ ...... yum file address

Enable = 1... apply this server

Gpgcheck = 0 ...... disable verification.

If the file cannot be saved, assign the permission.

Save and enter yum list for test.

(2) configure the local yum source)1. Create a mount point/mnt/cdrom

[Root @ ccc] # mkdir (create a new subdirectory)/mnt/cdrom

[Root @ ccc] # mount/dev/sr0/mnt/cdrom mount/dev/cdrom to the CD

Mount: block device (device)/dev/cdrom is write-protected, mounting read-only (success if this prompt is displayed)

2. Set

[Server]

Name = Server... name of the Server

Baseurl = file: // The file address of the mnt/cdrom/... yum Library

Enable = 1... apply this server

Gpgcheck = 0 ...... disable verification.

Test passed
