centos tftpsever 安装配置

1.安装 yum install tftp ; yum install tftp-server

2. 修改配置文件 /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
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot -c
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

3.重起xinetd服务 , service xinetd restart

4.修改SELinux参数,执行 setup 将安全级别降为 "允许"或"禁用",

或者修改文件

/etc/sysconfig/selinux

SELINUX=permissive

或

SELINUX=disabled

5.修改防火墙配置,放开UDP协议的69端口访问,编辑/etc/sysconfig/iptables,增加

-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 69 -j ACCEPT

service iptables restart

6.创建许可文件名,touch /tftpboot/file,并且修改文件权限,chown 777 /tftpboot/file

7.上传文件,tftp localhost

tftp> put file

tftp>quit
