High-rise flat bottom: Red Hat 7-series TFTP server Setup

TFTP is a simple File transfer protocol that is used during PXE deployment to transfer the initial boot program, kernel, and configuration files.

The following experiments were completed on CentOS 7.2

CentOS Linux release 7.2.1511 (Core)

[Email protected] ~]# uname-r

3.10.0-327.10.1.el7.x86_64

Yum Direct Installation

[Email protected] ~]# yum-y install Tftp-server

RPM Check configuration file path

-VVV record verbose log, this parameter is written in the last

/var/lib/tftpboot is the default TFTP home directory, if you modify this path remember to set SELinux-related permissions

Disable = no

Server_args =-s-c/VAR/LIB/TFTPBOOT-VVV

Restart Daemon xinetd Effective after modifying configuration file

[Email protected] ~]# systemctl restart Xinetd.service

Configure the boot autorun xinetd process

[Email protected] ~]# Systemctl enable Xinetd.service
