yum -y install tftp-server
By default, TFTP looks for all files in the /tftpboot/ directory. This directory is created automatically during the installation of the program.
The configuration of the tftp server is specified in the /etc/xinetd.d/tftp file, where you should change "disable = yes" to "disable = no". There, you can also change the directory for storing files: "server_args = -s -c /var/routerconfigs"
Enable xinetd:
service xinetd start
