11.tftp和nfs服务器

宿主机产生嵌入式软件的机器

运行程序的是目标机上运行

基于网络的下载

目标机通过tftp下载到目标机

1. 安装tftp依赖xinetd

[[email protected] Packages]# rpm -ivh xinetd-2.3.14-34.el6.i686.rpm

2. 安装tftp

[[email protected] Packages]# rpm -ivh tftp-server-0.49-7.el6.i686.rpm

3. 配置tftp

vim /etc/xinetd.d/tftp

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /home
disable = yes
per_source = 11
cps = 100 2
flags = IPv4
}

改为

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /home
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}

重启tftp服务

[[email protected] Packages]# /etc/init.d/xinetd restart

测试tftp服务

[[email protected] Packages]# /etc/init.d/iptables stop
iptables：清除防火墙规则： [确定]
iptables：将链设置为政策 ACCEPT：filter [确定]
iptables：正在卸载模块： [确定]
[[email protected] Packages]# setenforce permissive

在home目录下新建hello.c

输入tftp

用tftp32下载

2. nfs服务器网络文件系统

配置nfs文件服务器

[email protected] Packages]# vim /etc/exports

/tmp *(rw, sync, no_root_squash) # *所有用户， 192.168.1*网段

[[email protected] Packages]# /etc/init.d/nfs restart
