YUM is the package management tool that helps you to install or
update the package through the network or local, at the same time it
provides an easy method to install a package with its dependent
packages.
Repository sources can be created either using the createrepo package or mounting the DVD on the directory. Mounting the DVD/CD ROM will lead to saving the space on HDD used by being copied to HDD.
Local YUM with DVD
Install Package from Local DVD YUM repository
Let’s install the vsftpd package from the local repository.
You can use either FTP or Apache, not both.
Mount the DVD on /cdrom.
### FTP ### systemctl restart vsftpd ### Apache ### systemctl restart httpd
### For HTTP ### firewall-cmd --permanent --add-port=80/tcp firewall-cmd --reload ### For FTP ### firewall-cmd --permanent --add-port=21/tcp firewall-cmd --reload
FTP:
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 ipadress to your server ip address.
name=RHEL FTP
baseurl=ftp://192.168.1.10
enabled=1
gpgcheck=0
baseurl=http://192.168.1.10
enabled=1
gpgcheck=0
Repository sources can be created either using the createrepo package or mounting the DVD on the directory. Mounting the DVD/CD ROM will lead to saving the space on HDD used by being copied to HDD.
Local YUM with DVD
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.repoAdd the following details.
[LocalRepo] name=LocalRepository baseurl=file:///cdrom enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7Where,
[LocalRepo] – Name of the Section.
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
# yum install vsftpdThe 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.

Local YUM with FTP or HTTP
If you have quite number machines and all of them connected over 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 /cdromCopy packages from DVDROM to /var/ftp or /var/www/html receptively for FTP and Apache.
FTP
Copy the packages from the DVD-ROM to FTP folder.cp -a /cdrom/Packages/* /var/ftp
Apache
Copy packages from the DVD-ROM to Apache home directory.cp -a /cdrom/Packages/* /var/www/html/Edit Apache configuration file to enable the indexes.
vi /etc/httpd/conf/httpd.confFrom
Options Indexes FollowSymLinksTo
Options All Indexes FollowSymLinksRemove the welcome page.
rm -rf /etc/httpd/conf.d/welcome.conf
Restart service.
### 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
SELinux
Consider disabling SELinux on CentOS / RHEL.Verify Services
Verify the accessibility using the web browser by visiting respective service.FTP:
ftp://ip-address
Apache:
http://ip-address
Creating 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/ftpApache
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 ipadress to your server ip address.
FTP
[remote]name=RHEL FTP
baseurl=ftp://192.168.1.10

gpgcheck=0
Apache

Install Package from Local YUM repository
Now you can install packages using the yum command.
yum install mysql-server
