Install packages via local Yum Repository (follow the steps below if an internet connection is not accessible on CentOS server).
- Build a local repository, Download the Everything ISO.
  https://www.centos.org/download

Mount your CentOS 7 installation DVD. For example, let us mount the installation media on /mnt directory.
```
mount /dev/cdrom /mnt/
```

The CentOS installation DVD is mounted under /mnt directory. Next install vsftpd package and let the packages available over FTP to your local clients.
Change to /mnt/Packages directory.
```
cd /mnt/Packages/
```
Install vsftpd package, for instance.
```
rpm -ivh vsftpd-3.0.2-9.el7.x86_64.rpm
```
- Enable and start vsftpd service.
```
systemctl enable vsftpd
systemctl start vsftpd
```
- Create a storage location in our FTP server pub directory.
```
mkdir /var/ftp/pub/localrepo
```
- Install "createrepo" package, for instance.
```
rpm -ivh createrepo-0.9.9-23.el7.noarch.rpm
```
- Copy all the files from CentOS DVD(s) (i.e., from /mnt/Packages/ directory to the "localrepo" directory).
```
cp -ar /mnt/Packages/*.* /var/ftp/pub/localrepo/
```
- Once you copied all the files, create a repository file called "localrepo.repo" under /etc/yum.repos.d/ directory and add the following lines into the file. You can name this file as per your preference.
```
vi /etc/yum.repos.d/localrepo.repo
```
- Add the following lines:
```
[localrepo]
name=Unixmen Repository
baseurl=file:///var/ftp/pub/localrepo
gpgcheck=0
enabled=1
```
  Use three slashes (///) in the baseurl.
- Start building local repository.
```
createrepo -v /var/ftp/pub/localrepo/
```
- Clean the yum cache and update the repository lists.
```
yum clean all
```
- Alternatively, you can install packages only from the local repository by mentioning the repository as shown below.
```
yum install --disablerepo="*" --enablerepo="localrepo" compat-libstdc++-33.i686 kexec-tools fipscheck device-mapper-multipath sgpio perl-Convert-ASN1 python-dmidecode imake emacs libsane-hpaio tftp-server freeradius festival audit net-snmp-utils mesa-libGLU-devel xorg-x11-utils httpd vsftpd dhcp tigervnc* wireshark wireshark-gnome ksh mysql php-mysql php-pear php-common php-gd php-devel php php-mbstring php-cli php-snmp httpd net-snmp-utils php-snmp net-snmp-libs rrdtool net-snmp* gd gd-devel php-gd mariadb-server
