1.当然是使用yum安装最直接，一共会安装3个东东
tftp.i386
tftp-server.i386
xinetd.i386
[root@localhost
CentOS]# yum -y install
tftp*
2.安装完后可以使用rpm命令查看
[root@localhost
CentOS]#rpm -qa | grep
tftp
tftp-server-0.49-2.el5.centos
tftp-0.49-2.el5.centos
3.正式使用之前需要修改一下配置
[root@localhost
CentOS]# vi /etc/xinetd.d/tftp
# default: off
#
description: The tftp server serves files using the trivial file transfer
\
# protocol. The tftp protocol is often used to boot diskless
\
# workstations, download configuration files to network-aware
printers, \
# and to start the installation process for some
operating systems.
service
tftp
{
socket_type =
dgram
protocol = udp
wait =
yes
user = root
server =
/usr/sbin/in.tftpd
server_args = -s /tftpboot
‘加-c
disable = yes ‘改为no
#默认tftp服务是关闭的。
per_source = 11
cps = 100
2
flags =
IPv4
}
修改后的代码：
#
default: off
# description: The tftp server serves files using
the trivial file transfer \
# protocol. The tftp protocol is
often used to boot diskless \
# workstations, download
configuration files to network-aware printers, \
# and to start
the installation process for some operating systems.
service
tftp
{
socket_type =
dgram
protocol = udp
wait =
yes
user = root
server =
/usr/sbin/in.tftpd
server_args = -s /tftpboot
-c
disable = no
per_source =
11
cps = 100 2
flags =
IPv4
}
~
:wq
（保存退出）
说明：修改项server_args= -s
<path>
-c，其中<path>处可以改为你的tftp-server的根目录，参数-s指定chroot，-c指定了可以创建文件。
4.启动tftp服务
[root@localhost
CentOS]#cd /
[root@localhost /]# service xinetd
start
Starting xinetd: [ OK ]
[root@localhost
/]# setup ‘查看TFTP是否开机自动开启（系统服务选项） 查看防火墙是否开放TFTP端口，并在其他端口选项增加端口69：udp
，保存退出setup界面
5.修改tftp根目录权限
[root@localhost
/]# ls
backups dev lib misc opt sbin sys usr
bin
etc lost+found mnt proc selinux tftpboot var
boot home media net
root srv tmp
[root@localhost /]# cd
tftpboot/
[root@localhost tftpboot]#
ls
[root@localhost tftpboot]# cd
/
[root@localhost /]# chmod 777
tftpboot
6.重启tftp服务
[root@localhost /]#
service xinetd restart
Stopping xinetd: [ OK
]
Starting xinetd: [ OK ]
