Configure YUM Repository for Network Installation Using FTP and HTTP - Redhat Linux RHCE


YUM is the Linux package management tool that help to install or update the packages, it does automatic installation of dependent packages which is required by main installation package. To setup the YUM repository we need one server system where all the packages are hosted and the client system where you want to install or update the packages.

COPYING THE PACKAGES:

 In order to enable YUM repository through FTP or HTTP / Apache we have to copy the RPM packages to both the places. 

SERVER Side:

Install FTP server packages. 

~]# yum install vsftpd*

Start the FTP service
~]# service vsftpd restart
Shutting down vsftpd:                                      [FAILED]
Starting vsftpd for vsftpd:                                [  OK  ]

~]# chkconfig vsftpd on
~]# service iptables stop


Now Install HTTP server packages

~]#yum install http*
~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]


Edit Apache configuration file to enable the indexes.
~]#vi /etc/httpd/conf/httpd.conf
 
From
~]#Options Indexes FollowSymLinks
 
To
~]#Options All Indexes FollowSymLinks
 
Remove the welcome page.
~]#rm -rf /etc/httpd/conf.d/welcome.conf
 
Restart the httpd service after changing the settings
 
~]#service httpd restart
 
Verify the above using the web browser by visiting ftp://ip-address or http://ip-address.

Copy the packages to FTP Path

Assuming  /media/RHEL is the Mount of the CD/DVD of installation media.

~]# cp -Rv /media/RHEL/Server/* /var/ftp/pub/

copy the packages to HTTP path as well

~]#cp -Rv /media/RHEL/Server/* /var/www/html/

Creating Repository:

  After hosting the packages, we need to create the repository of the packages that you have copied from the disc. CreateRepo is the tool that help you to create the XML based rpm meta structure repository, It is like an index file that point to the rpm files. This XML files used for resolving the dependency packages which is required by main package.Install CreateRepo package.

install the below RPM's before running createrepo command

~]#rpm -Uvh deltarpm-**.el6.x86_64.rpm python deltarpm-**.el6.x86_64.rpm createrepo-**.rpm
 
For FTP

~]#createrepo -v /var/ftp/pub/

For HTTP

~]# createrepo -v /var/www/html/

after completing the repository creation Go to client side configure the client to get repo from server

Client Side Configuring Repository:

Once created the repository, just go on to the client machine and add the repository file under the /etc/yum.repos.d directory. Change ipadress to your server ip address..

~]# vi /etc/yum.repos.d/remoteftp.repo

#FTP
[remote] name=RHEL FTP
baseurl=ftp://192.168.0.151
enabled=1
gpgcheck=0

~]# vi /etc/yum.repos.d/remotehttp.repo

#HTTP
[remote] name=RHEL Apache
baseurl=http://192.168.0.151
enabled=1
gpgcheck=0

Install Packages using YUM:

~]#yum install PackageName

Conclusion:

From the above you could see the MySQL Server packages installed with all dependent packages, It performs the same task that RPM can. It provides a easy installation of packages in single command line. If you face any problem on FTP or Apache, do disabling the iptables
