BASH Cures Cancer

How to install CentOS 4.4 (Red Hat Enterprise Linux) from an FTP server in TEXT mode. This is knowledge which
is needed for the RHCE Exam. The only prerequisite is that you have a server with FTP already running or
the ability to start the/a FTP server.

1. If you are not currently running a ftp on your server, you will need to setup the daemon. Here is the steps
   for a CentOS 4.4 server with no firewall configured and SELinux disabled:

   [root@localhost ~]# yum install vsftpd
   	*** ouput removed as its of no interest ***
   [root@localhost ~]# chkconfig --level 35 vsftpd on
   [root@localhost ~]# /etc/init.d/vsftpd start
   Starting vsftpd for vsftpd:                                [  OK  ]

2. Create a directory on your ftp server in /var/ftp/pub (CentOS only). Mine is /var/ftp/pub/centos4.4.
   I will call this directory $CENTOS_FTP_ROOT.

   [root@localhost ~]# mkdir /var/ftp/pub/centos4.4
   [root@localhost ~]# cd /var/ftp/pub/centos4.4

3. Download the CentOS ISO files. You can download the DVD image or regular ISOs.
4. Extract all the ISOs or DVD into the $CENTOS_FTP_ROOT directory. You can do this by mounting the ISO directly and then copying the contents to $CENTOS_FTP_ROOT. This link is a good description on how to mount an iso.

   [root@localhost centos4.4]# pwd
   /var/ftp/pub/centos4.4
   [root@localhost centos4.4]# ls -al
   total 744
   drwxr-xr-x  8 root root   4096 Feb  5 22:32 .

   drwxr-xr-x  2 root root   4096 Feb  5 22:25 isolinux
   drwxr-xr-x  2 root root   4096 Feb  5 22:25 NOTES

   -rw-r--r--  1 root root   7014 Aug 23 14:49 RELEASE-NOTES-en.html
   drwxr-xr-x  2 root root   4096 Feb  5 22:25 repodata
   -rw-r--r--  1 root root   1795 Feb 28  2005 RPM-GPG-KEY

   -rw-r--r--  1 root root 569869 Aug 12 10:38 yumgroups.xml

5. Now that you have ftp server setup, test it:

   [root@localhost ~]# ftp localhost
   Connected to localhost.localdomain.
