Installing and Updating Software/Package after Configure yum in RHEL 7

RPM (Redhat Package Manager) package files  are  named using a  combination of the package name-version -release . architecture: 

[root@rhel7 Packages]# ls -lrt httpd*
-r--r--r--.  75 root root 1211944 Apr  1  2014 httpd-2.4.6-17.el7.x86_64.rpm

•  NAME is one or more words describing the contents (httpd). 

•  VERSION is the version number of the original software (2.4.6). 

•  RELEASE  is  the re lease number of  the package based on that version, and  is  set by the 

packager, who might not be the original software developer (17.e l7). 

•  ARCH  is the processor architecture the package was  compiled  to run on.  "noarch" indicates 

that  this package's contents are  not architecture-specific (x86_64). 

yum is a  powerful command-line tool that can be used to more  flexibly manage (install, update, remove,  and query) software packages. Official  Red Hat packages  are  normally  downloaded from Red Hat's content distribution network. Registering a  system to the subscription management service automatically configures access  to software repositories based on the attached subscriptions. 

Step 1: Create a directory to collect the packages into that directory

[root@rhel7 Packages]# mkdir /yum

[root@rhel7 Packages]# cd /run/media/root/RHEL-7.0 Server.x86_64/Packages   [go to DVD]

[root@rhel7 Packages]# cp -r * /yum            [copy all packages including sub directory to /yum ]

Step 2: Create a repository 

[root@rhel7 Packages]# createrepo /yum

Step 3: Add a .repo file into /etc/yum.repos.d directory

To make this repository known to yum you need to add a .repo file to your yum configuration. On the systems where you want to use this repo you need to make a new file in /etc/yum.repos.d/. The file can be named anything but the extension on the file has to be .repo. Let's call this one 'sirat.repo'.

[root@rhel7 yum.repos.d]# vim sirat.repo

[sbl]

name=Standard Bank Limited

baseurl=file:///yum

gpgchek=0

enabled=1

Note: there are 3 slashes (/) following the file:, not 2. That is correct.

If you access the file via an http or https server you would use something like:

baseurl = http://servername/my/repo

Step 4: Now check that yum repository configured or not ??

[root@rhel7 yum.repos.d]# yum repolist

Loaded plugins: langpacks, product-id, subscription-manager

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

sbl                                                                                                                  | 2.9 kB  00:00:00

sbl/primary_db                                                                                              | 3.4 MB  00:00:01

repo id                                   repo name                                                                   status

sbl                                         Standard Bank Limited                                               4,305

repolist: 4,305

[root@rhel7 yum.repos.d]#

Step 5: Install new packages

[root@rhel7 yum.repos.d]# yum install httpd

Loaded plugins: langpacks, product-id, subscription-manager

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Step by Step : How to configure YUM Server in RHEL6

Make directories yum/rhel6/repodata in the folder which you have chosen for repository.

For FTP server it would be /var/ftp/pub folder

[root@dpdcdb repodata]# mkdir -p /var/ftp/pub/yum/rhel6/repodata/

Copy all RPM from RHEL 6 DVD located in Packages folder to [root@dpdcdb repodata]#

[root@dpdcdb repodata]# cp -arf /media/RHEL_6.2\ x86_64\ Disc\ 1/Packages/*.rpm /var/ftp/pub/yum/rhel6/repodata/


root@dpdcdb repodata]# cp /media/RHEL_6.2\ x86_64\ Disc\ 1/repodata/*comps*.xml /var/ftp/pub/yum/rhel6/repodata/comps.xml
[root@dpdcdb repodata]#

[root@dpdcdb RHEL_6.2 x86_64 Disc 1]# cd Server/
[root@dpdcdb Server]# rpm -qa deltarpm
[root@dpdcdb Server]# rpm -qa python-deltarpm
[root@dpdcdb Server]# rpm -qa createrepo
[root@dpdcdb Server]# pwd

Configure Yum repository in Linux

Create a folder in the server.

mkdir -p /var/ftp/pub/Server

Copy all RPMs from Linux DVD to Here.

Create the base repository headers:

cd /var/ftp/pub/Server/
rpm –ivh createrepo*

Paste database file to /tmp location

cd repodata/
cp comps* /tmp/comps.xml

Create repository

createrepo –g /tmp/comps.xml /var/ftp/pub/Server

Add your local repo to the list

cd /etc/yum.repos.d/
rm *
touch server.repo

Edit the File server.repo:

[server]
name= My Local Repo
baseurl=file:///var/ftp/pub/Server
enabled=1
gpgcheck=0
