[root@localhost Server]# netstat -a |grep tftp
udp 0 0 *:tftp *:*
若没有安装,在Redhat Enterprise Linux 5的安装光盘中有RPM安装包,挂在光盘后进入到文件夹,找到相应的安装包。
[root@localhost user]# cd /media/
[root@localhost media]# ls
RHEL_5.1 i386 DVD
[root@localhost media]# cd RHEL_5.1\ i386\ DVD/
[root@localhost RHEL_5.1 i386 DVD]# ls
[root@localhost RHEL_5.1 i386 DVD]# cd Server/
[root@localhost Server]# ls tftp*
tftp-0.42-3.1.i386.rpm tftp-server-0.42-3.1.i386.rpm
执行安装命令
[root@localhost Server]# rpm -ivh tftp-server-0.42-3.1.i386.rpm
warning: tftp-server-0.42-3.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
xinetd is needed by tftp-server-0.42-3.1.i386
提示需要安装xinetd,找到安装包并安装
[root@localhost Server]# ls xinet*
xinetd-2.3.14-10.el5.i386.rpm
[root@localhost Server]# rpm -ivh xinetd-2.3.14-10.el5.i386.rpm
warning: xinetd-2.3.14-10.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

再执行安装TFTP命令
[root@localhost Server]# rpm -ivh tftp-server-0.42-3.1.i386.rpm
warning: tftp-server-0.42-3.1.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

建立tftp的主工作目录
[root@localhost Server]# mkdir /tftpboot
修改配置文件
[root@localhost Server]# vi /etc/xinetd.d/tftp
主要注意修改的两个地方:
# 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
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
重启服务
[root@localhost Server]# /etc/init.d/xinetd restart
Stopping xinetd: [FAILED]
Starting xinetd: [ OK ]
查看是否启动
[root@localhost Server]# netstat -a |grep tftp
udp 0 0 *:tftp *:*
