Yum Introduction
Yum is called Yellow dog Updater. Modified (Package Manager) is also called "Yellow dog" when we joke"
The main function is to conveniently Add/delete/update RPM packages. yum can check the dependency between software packages installed in linux and automatically install all dependent software packages, it facilitates management of a large number of system updates,
Multiple resource libraries can be set at the same time, and it is very easy to use.

The following describes how to configure a repository on RHEL5:
1. Use FTP to create the yum installation Source
Server IP Address: 192.168.200.101
[Root @ localhost ~] # Mount/dev/cdrom/media
[Root @ localhost ~] # Cd/media/Server/
[Root @ localhost Server] # ls | grep vsftpd
Vsftpd-2.0.5-16.el5.i386.rpm
Because the yum repository is not configured yet, you can use rpm to install ftp.
[Root @ localhost Server] # rpm-ivh vsftpd-2.0.5-16.el5.i386.rpm
Warning: vsftpd-2.0.5-16.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing... ######################################## ### [100%]
1: vsftpd ####################################### #### [100%]
We can see that the FTP software has been installed successfully.
After the FTP service is installed, a/var/ftp/pub directory is generated by default.
[Root @ localhost ~] # Cd/var/ftp/pub/
[Root @ localhost pub] # ls
Now there is nothing in this directory. We will copy everything in the CD to this directory.
[Root @ localhost ~] # Cp-p/media/*/var/ftp/pub/
[Root @ localhost ~] # Cd/var/ftp/pub/
[Root @ localhost pub] # ll | grep ^ d
Cluster ClusterStorage Server VT
There are four folders under the/var/ftp/pub directory.
Start the FTP service:
[Root @ localhost ~] # Service vsftpd restart
Shutting down vsftpd: [OK]
Starting vsftpd for vsftpd: [OK]

Configure the yum repository now,
The Yum repository is under the/etc/yum. repod directory (the file name must end with. repo)
[Root @ localhost ~] # Cd/etc/yum. repos. d/
[Root @ localhost yum. repos. d] # ls
Rhel-debuginfo.repo
There is a rhel-debuginfo.repo template file under the/etc/yum. repos. d directory, you can configure the yum repository according to the content in this file.
[Root @ localhost yum. repos. d] # vi rhel-debuginfo.repo
We can follow the content in this section to add the following content:
[Rhel-Server]
Name = Red Hat Enterprise Linux Server
Baseurl = ftp: // 192.168.200.101/pub/Server
Enabled = 1
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[Rhel-Cluster]
Name = Red Hat Enterprise Linux Cluster
Baseurl = ftp: // 192.168.200.101/pub/Cluster
Enabled = 1
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[Rhel-ClusterStorage]
Name = Red Hat Enterprise Linux ClusterStorage
Baseurl = fttp: // 192.168.200.101/pub/ClusterStorage
Enabled = 1
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[Rhel-VT]
Name = Red Hat Enterprise Linux VT
Baseurl = fttp: // 192.168.200.101/pub/VT
Enabled = 1
Gpgcheck = 1
Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
