HTTP installation of RHEL6/CentOS/SL-6

On Server

• Install apache server (HTTP server) using yum

#yum install httpd

Note: if you don’t know how to setup yum you can see this post

• Mount the DVD (which is also specified in the above post) and copy the content to /var/www/html/cdrom

For example, if DVD is mounted to /cdrom directory, then

#cp –vrf /cdrom /var/www/html/

Note: alternatively, we can mount the DVD directly to the web accessible, /var/www/html/ path

• Now, start the http service

#service httpd start

• Check the setting using the web browser with server’s IP. If server IP is 192.168.1.10 then use http://192.168.1.10/cdrom 

Note: if firewall is on, turn off firewall or add exception to port 80

 

On the installation system

• Download boot.iso from redhat.

Note: boot.iso not ship with DVD now. So we need to download it from redhat site. Alternatively we can use CentOS netinstall.iso, both are same

• CentOS 6 netinstall.iso is available here: 

http://mirrors.hns.net.in/centos/6.0/isos/x86_64/CentOS-6.0-x86_64-netinstall.iso

http://mirrors.hns.net.in/centos/6.0/isos/i386/CentOS-6.0-i386-netinstall.iso

• Write the the image to a CD and put it in the CD-ROM drive. Alternatively, we can use USB key. It is explained here.
• Reboot the system and supply the following boot string at the end of current line without quotes by pressing tab

'linux repo=http://192.168.1.10/cdrom ip=192.168.1.20 netmask=255.255.255.0 gateway=192.168.1.1 dns=192.168.1.1'

Note: if more than one DNS server is available specify it using comma. DNS server address is optional. Here IP is the address of the current system
