For reference:
On this notes i have used Red Hat Enterprise 7. This notes should be almost be like same procedure when you use other Red hat version may only differ at some points which i will try to determine.
i have already transferred some iso files on /images/iso directory.
[root@eSuareznotes01 html]# ls -l /images/iso/ total 11694384 -rw-r--r--. 1 root root 4378114048 Jul 4 17:48 rhel-server-5.10-x86_64-dvd.iso -rw-r--r--. 1 root root 3853516800 May 23 17:22 rhel-server-6.5-x86_64-dvd.iso -rw-r--r--. 1 root root 3743416320 Jul 13 04:32 rhel-server-7.0-x86_64-dvd.iso
Lets us begin and bear with my silly notes:
[root@eSuareznotes01 ~]# mkdir -p /images/linux_CD/rhel7_u0x64 #Create the directory where you will place the files.
[root@eSuareznotes01 ~]# mount -o loop /images/iso/rhel-server-7.0-x86_64-dvd.iso /mnt #Mount the Red Hat iso file
mount: /dev/loop0 is write-protected, mounting read-only
[root@eSuareznotes01 ~]# cp -arv /mnt/. /images/linux_CD/rhel7_u0x64/ #Copy the mounted file to the local directory
[root@eSuareznotes01 ~]# umount -l /mnt/ #unmount the mounted partition
Now Create the local repo file.
for local server: Note: don’t forget to use three slashes in the baseurl if your repointing it to a file location
[root@eSuareznotes01 ~]# vi /etc/yum.repos.d/rhel7_u0x64.repo #You can choose whatever filename, i named mine as rhel7_u0x64.repo
[rhel7_u0x64] name=RHEL 7.0 64-bit on localhost baseurl=file:///images/linux_CD/rhel7_u0x64 gpgcheck=1 gpgkey=file:///images/linux_CD/rhel7_u0x64/RPM-GPG-KEY-redhat-release enabled=1
[root@eSuareznotes01 ~]# yum repolist #Do yum repo list

On the installation guide I have made mentioned there that “the iso I used is based on April 2014 release so likely that is not the latest kernel that was out June 2014 release. Latest kernel should be kernel 3.10.0-123.”
For the purpose of this guide that came in handy since the iso I uploaded to my system is from June 2014 release we then can test if yum would work fine.
i will be doing system update on the system

Now i will be using http as protocol for my local repo so it can push files to the network.
[root@eSuareznotes01 ~]# yum -y install httpd perl perl-CGI php php-pear #perl perl-CGI php php-pear is not necessary I installed it for future use
For Red Hat Enteprise 7 only
[root@eSuareznotes01 ~]# systemctl start httpd.service #Start httpd service process
[root@eSuareznotes01 ~]# systemctl enable httpd.service #Enable system service to start every boot time
ln -s ‘/usr/lib/systemd/system/httpd.service’ ‘/etc/systemd/system/multi-user.target.wants/httpd.service’
For other Red Hat version
[root@rhel6~]# /etc/rc.d/init.d/httpd start #Start httpd service
Starting httpd: [ OK ]
[root@rhel6 ~]# chkconfig httpd on #Enable service to start at reboot
Since i am using the file hosted on other partition i have repoint it to show contents on the httpd directory which is located at /var/www/html
[root@eSuareznotes01 ~]# ln -s /images/iso/ /var/www/html/iso
[root@eSuareznotes01 ~]# ln -s /images/linux_CD/ /var/www/html/linux_CD
Configuring firewalld to allow http connection #For Red Hat Enteprise 7.0 only as other version uses iptables instead
This should serve as sample on how to configure firewalld and some sets of commands:
Check which zone are you running:
[root@eSuareznotes01 zones]# firewall-cmd –get-active-zone
public
interfaces: eth0
[root@eSuareznotes01 zones]# firewall-cmd –zone=external –change-interface=eth0
success
[root@eSuareznotes01 zones]# firewall-cmd –get-active-zone
external
interfaces: eth0
[root@eSuareznotes01 zones]# firewall-cmd –zone=external –list-services
ssh
[root@eSuareznotes01 system]# firewall-cmd –zone=external –add-service=http
success
[root@eSuareznotes01 system]# firewall-cmd –zone=external –list-all
external (active)
interfaces: eth0
sources:
services: ssh
ports: 300/tcp
masquerade: yes
forward-ports:
icmp-blocks:
rich rules:
Configure Iptables to allow http connection #For other Red hat version that uses iptable by default
vi /etc/sysconfig/iptables
Add this lines under INPUT sections
-A INPUT -p tcp -m tcp –dport 80 -j ACCEPT
Save the file and restart iptables.
/etc/init.d/iptables restart
Selinux
[root@eSuareznotes01 /]# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
Check SELinux security context
[root@eSuareznotes01 /]# ls -Z /var/www/html/
-rw-r–r–. root root unconfined_u:object_r:httpd_sys_content_t:s0 index.html
lrwxrwxrwx. root root unconfined_u:object_r:httpd_sys_content_t:s0 iso -> /images/iso/
lrwxrwxrwx. root root unconfined_u:object_r:httpd_sys_content_t:s0 linux_CD -> /images/linux_CD/
-rw-r–r–. root root unconfined_u:object_r:httpd_sys_content_t:s0 phpinfo.php
[root@eSuareznotes01 /]# chcon -Rv –type=httpd_sys_content_t /images
After allowing on the firewalld and SELinux you should be able to see over the network the contents
You should be able to reach the contents http://xxx.xxx.xxx.xxx/linux_CD/
On remote machine configuration
vi /etc/yum.repos.d/whatevername.repo
[rhel7_u0x64] name=RHEL 7.0 64-bit on localhost baseurl=http://xxx.xxx.xxx.xxx/linux_CD/rhel7_u0x64 gpgcheck=1 gpgkey=http://xxx.xxx.xxx.xxx/linux_CD/rhel7_u0x64/RPM-GPG-KEY-redhat-release enabled=1
Where xxx.xxx.xxx.xxx is the ip of your local repo server
Will Update…
