Yum builds a local repository and installs software

The local area network is used to build a local lab environment, which is not convenient for downloading software from the network. Therefore, you need to build a local software warehouse to easily install yum. Of course, the dependency between software Packages can be well handled. If you are familiar with the rpm installation method of Linux, you can install the software by using rpm. You can directly go to the Packages directory of the mounted disc to install the rpm.

[Yum installation method]

1. Insert the red hat system installation disc

Virtual Machine environment:

Method 1: There is a small CD icon in the lower right corner of the page. Click Settings. In settings, find the CD location in the local path and click OK;

Method 2: on the task bar of VMware Workstation, click "virtual machine" ---> "removable device" ---> "CD/DVD" --- "set ", find the disc location in the local path in the settings, and confirm it. The method is the same as above;

Real machine environment:

Insert the installation disc directly;

2. Attach the CD to a local device.

[Email protected]/] # mount/dev/sr0/mnt

3. Compile the rhel6.repo configuration file to build a repository.

Vim/etc/yum. repos. d/rhel6.repo
