REDHAT 7: How to create a local yum repo server

Inorder to create a local yum repo server follow the steps below.

STEP 1: Copy the iso image to a location in which you are going to create an yum repo.

STEP 2: Mount the iso image, using the below command:
--------
mount -o loop rhel-server-7.0-x86_64-dvd.iso /mnt
--------

STEP 3: Install the following packages in the server.
--------
rpm -ivh /mnt/Packages/vsftpd-*.rpm
rpm -ivh /mnt/Packages/deltarpm-*.rpm
rpm -ivh /mnt/Packages/python-deltarpm-*.rpm
rpm -ivh /mnt/Packages/createrepo-*.rpm

--------

STEP 4: Start vsftpd service using below command:

-------------
systemctl start vsftpd.service ---> To start service
systemctl enable vsftpd.service---> To enable on start up.
systemctl is-enabled vsftpd.service---> To check whether the service is enabled.
--------------

STEP 5: Copy installation tree.

------
mkdir -p /var/ftp/pub/rhel7

cp -rp /mnt/* /var/ftp/pub/rhel7/
cd /var/ftp/pub/rhel7
-------

STEP 6:  Create repository using "createrepo" command.

---------
createrepo -g repodata/*-comps-Server.x86_64.xml .
---------

The above output result shows that, yum has been created successfully.


STEP 7:  Create a repo file as "/etc/yum.repos.d/rhel70.repo"

The file looks as below:

-----------
[root@SERVER]#cat  /etc/yum.repos.d/rhel70.repo
[rhel7]
name=RHEL 7.0
baseurl=ftp://192.168.150.152/pub/rhel7
gpgcheck=0
enabled=1

------------

In which, "192.168.150.152" is the ip address of my local machine.

STEP 8: Use the below commands to clean repository and list the available packages.

----------

yum clean all

yum repolist

----------
