How to configure yum repository server on OEL 6.5

Configure Linux yum server step by step

 What is YUM command?

YUM stands for Yellow dog Updater, Modified because it is based on YUP, the Yellow dog Updater. Yellow Dog is a version of Linux for the Power Architecture hardware. YUP, and later YUM, were written by the Linux community as a way to maintain an RPM-based system.

Uses of YUM Command?

Automatic resolution of software dependencies. If a package installation or upgrade request is made and requires the installation or upgrade of additional packages, YUM can list these dependencies and prompt the user to install or upgrade them.

Command-line and graphical versions. The command-line version can be run on a system with a minimal number of software packages. The graphical versions offer ease-of-use and a user-friendly graphical interface to software management.

Multiple software locations at one time. YUM can be configured to look for software packages in more than one location at a time.

Ability to specify particular software versions or architectures. Software locations accessible by YUM can contain multiple versions of the same RPM package and different builds for different architectures such as one for i686 and one for x86_64. yum can easily check the appropriate version and download it.

While it's unlikely that you'll have an Internet connection during the exam, you could have a network connection to a local repository. So you should be ready to use the yum command during the Red Hat exam.

[root@test ~]#  service vsftpd status

to start the FTP Service execute the following command

[root@test ~]#  service vsftpd start

to permanently start FTP Service execute the following command

[root@test ~]#  chkconfig vsftpd on

STEP:-4

 Now go to "/var/ftp/pub/" directory and then create a directory in it named "IT".

to go to "/var/ftp/pub/", execute the following command

[root@test ~]#  cd /var/ftp/pub/

to create a directory named IT, execute the following command

[root@test ~]#  mkdir IT

STEP:-5

 Copy the entire OEL 6 DVD in the "/var/ftp/pub/IT/" directory.

to copy the entire OEL 6.5 DVD in the "/var/ftp/pub/IT/", use the following command

STEP:-7

 In the next step create the configuration file of YUM Server in "/etc/yum.repos.d/" directory and add the following line in it.

[server]
name=YUM-Server
baseurl=ftp://192.168.1.101/pub/IT
enabled=1
gpgcheck=0

Note :- where 192.168.1.101 is the IP address of your PC on which you configure YUM-Server.

to create the configuration file of YUM Server in "/etc/yum.repos.d/", use the following command

[root@test ~]# vi /etc/yum.repos.d/server.repo

[root@test yum.repos.d]# cat server.repo
[server]
name=YUM-Server
baseurl=ftp://192.168.1.115/pub/IT
enabled=1
gpgcheck=0
[root@test yum.repos.d]#

STEP:-8

 Now install any  packages using YUM-Server.

 to install any packages using YUM-Server, execute the following command
