BOOTPROTO=static

ONBOOT= yes

IPADDR = 172.17.1.xx As per your requirement

NETMASK = 255.255.255.0 As per your requirement

#cd /mnt/Packages

#rpm –ivh vsftpd10cgxxxx…….rpm

#rpm –ivh createrepo120xxx…..rpm

#mkdir –p /var/ftp/pub/rhel7/dvd

#cp –rvf /mnt/* /var/ftp/pub/rhel7/dvd

#cd /etc/yum.repos.d/

#ls –l

If any thing is present then delete all

By Ayaz Ullah Khan
