CentOS6.5 TFTP搭建	2018-08-26	Centos6.5服务器搭建	post

1.安装TFTP服务

yum install tftp-server
yum install xinetd        //TFTP是通过xintd运行的，所以需要安装Xinetd

2.配置tftp文件

vim /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
{
    socket_type     = dgram
    protocol        = udp
    wait            = yes
    user            = root
    server          = /usr/sbin/in.tftpd
    server_args     = -s /var/lib/tftpboot        //FTP文件的根目录
    disable         = no        //缺省请况下是禁用TFTP的，所以要把yes改为no
    per_source      = 11
    cps             = 100 2
    flags           = IPv4
}

4.设置TFTP目录的访问权限

chmod 777 /var/lib/tftpboot

5.开启TFTP服务

[root@localhost /]# /etc/init.d/xinetd start

可能出现的问题

1.tftpd服务没有启动

2.需要把selinux禁用掉 具体方法如下：

vim /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
SELINUX=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

把上面的SELINUX=enforcing 改为：SELINUX=disable 禁用SeLinux 然后reboot重启PC
