CentOS-Base.repo

#

The mirror system uses the connecting IP address of the client and the

update status of each mirror to pick mirrors that are updated to and

geographically close to the client. You should use this for CentOS updates

unless you are manually picking other mirrors.

#

If the mirrorlist= does not work for you, as a fall back you can try the

remarked out baseurl= line instead.

centos7安装tftp服务器
1.安装
su　　#进入root
yum install xinetd
yum install tftp
yum install tftp-server
回到顶部(go to top)
2.配置tftp
vim /etc/xinetd.d/tftp
修改下面红框部分！
server_agrs改为自己准备存放的目录,并修改所设文件夹的权限
disable改为no

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

3.重启tftp服务
systemctl restart xinetd 启动服务
systemctl enable xinetd.service
systemctl enable xinetd.service 加入开机自动启动服务
回到顶部(go to top)
4.测试tftp
windows下ping一下linux的ip看是否可以通；
ping通之后关闭linux的防火墙： systemctl stop firewalld.service
启动windows客户端。
