YUM Server Configuration on RedHat Lunix

 Configure Local Yum Repository using ISO in RHEL 7 - CentLinux

Create Source

Mount the CD/DVD ROM on any directory of your wish. For testing, mount it on /cdrom.

mkdir /cdrom mount /dev/cdrom /cdrom

Create Repo file

Before creating a repo file, move your existing repo files present in /etc/yum.repos.d directory, if not required.

mv /etc/yum.repos.d/*.repo /tmp/

Create the new repo file called cdrom.repo under /etc/repos.d directory.

vi /etc/yum.repos.d/local.repo

Add the following details.

[LocalRepo] name=LocalRepository baseurl=file:///cdrom enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

Where,

[LocalRepo] = Repository Name which will be displayed during package installation

name = Name of the repository

baseurl = Location of the package

Enabled = Enable repository

gpgcheck = Enable secure installation

gpgkey = Location of the key

gpgcheck is optional (If you set gpgcheck=0, there is no need to mention gpgkey)

Install Package from Local DVD YUM repository

Clear the repository cache by issuing the following command.

yum clean all

Let’s install the vsftpd package from the local repository.

yum install vsftpd

The output will be like below; it will try to cache the package information. When you give yes to download the package, it will prompt you to accept gpg signing key.

You have successfully configured the local repository on the machine, but it is limited to a single machine where the CD or DVD is mounted.

Create Local YUM Repository with FTP or HTTP

If you have quite number machines and all of them connected over the intranet, then this is the best option for you.

Host RPM Packages

Normally YUM server uses FTP or Apache as the medium to transfer packages. So, install either FTP or Apache on your yum server.

You can use either FTP or Apache, not both.

Mount the DVD on /cdrom.

mkdir /cdrom;mount /dev/cdrom /cdrom

Copy packages from DVDROM to /var/ftp or /var/www/html receptively for FTP and Apache.

FTP

Copy the packages from the DVD-ROM to the FTP folder.

cp -a /cdrom/Packages/* /var/ftp

Apache

Copy packages from the DVD-ROM to the Apache home directory.

cp -a /cdrom/Packages/* /var/www/html/

Edit Apache configuration file and 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 Services

### FTP ### systemctl restart vsftpd ### Apache ### systemctl restart httpd

Firewall

You need to allow FTP and HTTP port on the firewall so that client machines can able to get packages from YUM server.

### For HTTP ### firewall-cmd --permanent --add-port=80/tcp firewall-cmd --reload ### For FTP ### firewall-cmd --permanent --add-port=21/tcp firewall-cmd --reload

Verify Services

Verify the accessibility using the web browser by visiting respective service.

FTP:

ftp://ip-address

Apache:

http://ip-address

Create Repository

After hosting the packages, we need to create the repository of packages that we have copied from the disc. createrepo is the tool that helps you to create the XML based rpm meta-structure repository, like an index file that points to rpm files.

cd /cdrom/Packages rpm -ivh createrepo-*el7.noarch.rpm libxml2-python-*.x86_64.rpm deltarpm-*.el7.x86_64.rpm python-deltarpm-*el7.x86_64.rpm

FTP

createrepo /var/ftp

Apache

createrepo /var/www/html

Create Repo File

Once created the repository, just go on to the client machine and add the repository file under the /etc/yum.repos.d directory.

Before creating a repo file, move the existing repo files present in /etc/yum.repos.d directory, if not required.

mv /etc/yum.repos.d/*.repo /tmp/

Create remote.repo file.

vi /etc/yum.repos.d/remote.repo

Create a repo entry like below, depends on the protocol you are using. Change IP address to your server ip address.

FTP

[remote] name=RHEL FTP baseurl=ftp://192.168.1.10 enabled=1 gpgcheck=0

Apache

[remote] name=RHEL Apache baseurl=http://192.168.1.10 enabled=1 gpgcheck=0

Install Packages from Local YUM repository

Now you can install packages using the yum command.

yum -y install mariadb-server mariadb
