RedHat Enterprise Linux 5 安装TFTP服务器

利用以下命令就可以看到TFTP服务器已启动，则不用安装

[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/（进入光盘文件命令必须这个格式，注意R、i、D前有空格）
[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
Preparing... ########################################### [100%]
1:xinetd ########################################### [100%]

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
Preparing... ########################################### [100%]
1:tftp-server ########################################### [100%]

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(看红色标示处是否对的，不对修改)：

# 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     *:*
