基础服务安装：

[root@ftp ~]# mount /dev/cdrom /mnt

mount: block device /dev/sr0 is write-protected, mounting read-only

[root@ftp ~]# yum -y install vsftpd bind bind-chroot bind-utils dhcp

1.配置dhcp服务：

[root@ftp ~]# vi /etc/dhcp/dhcpd.conf

:r /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample  ##读取模板配置

:%g/^#/d  ##删除注释

:%g/^$/d  ##删除空行

option domain-name "linuxfan.cn";

option domain-name-servers 192.168.100.110;

default-lease-time 600;

max-lease-time 7200;

log-facility local7;

subnet 192.168.100.0 netmask 255.255.255.0 {

range 192.168.100.50 192.168.100.99;

option routers 192.168.100.117;

next-server 192.168.100.110;

filename "pxelinux.0";

}

:wq

[root@ftp ~]# /etc/init.d/dhcpd start

正在启动 dhcpd：                                           [确定]

[root@ftp ~]# chkconfig dhcpd on

[root@ftp ~]# netstat -utpln |grep dhcp

udp        0      0 0.0.0.0:67         0.0.0.0:*            1264/dhcpd

2.配置ftp服务：

1)修改vsftpd配置并实现要求：

[root@ftp ~]# cd /etc/vsftpd/

[root@ftp vsftpd]# cp vsftpd.conf vsftpd.conf.bak  ##备份配置文件

[root@ftp vsftpd]# vi vsftpd.conf

:%g/^$/d

:%g/^#/d

修改如下：

anonymous_enable=YES

local_enable=YES

write_enable=YES

local_umask=022

dirmessage_enable=YES

xferlog_enable=YES

connect_from_port_20=YES

xferlog_std_format=YES

chroot_local_user=YES

ls_recurse_enable=NO

listen=YES

pam_service_name=vsftpd

userlist_enable=YES

tcp_wrappers=YES

pasv_enable=YES

pasv_max_port=24600

chown_uploads=YES

chown_username=u01

local_root=/var/ftproot/

anon_root=/var/ftproot/

ftpd_banner=Welcome to linuxfan.cn FTP service.

anon_upload_enable=NO

listen_address=192.168.100.110

local_umask=022

:wq

[root@ftp vsftpd]# useradd -d /var/ftproot -c "ftp admin user" -u 110 u01; echo pwd@123 |passwd --stdin u01

[root@ftp vsftpd]# id u01

uid=110(u01) gid=500(u01) 组=500(u01)

[root@ftp vsftpd]# grep u01 /etc/passwd

u01:x:110:500:ftp admin user:/var/ftproot:/bin/bash

[root@ftp vsftpd]# chmod 755 /var/ftproot/

[root@ftp vsftpd]# /etc/init.d/vsftpd restart

[root@ftp vsftpd]# netstat -utpln |grep ftp

tcp     0    0     192.168.100.110:21    0.0.0.0:*         LISTEN      1310/vsftpd

[root@ftp vsftpd]# chkconfig vsftpd on

2)访问测试：

3.配置dns服务：

修改配置文件：

[root@ftp ~]# cd /var/named/chroot/etc/

[root@ftp etc]# cp /usr/share/doc/bind-9.8.2/sample/etc/named.conf ./

[root@ftp etc]# vi named.conf   #主配置文件

修改如下：

options

{

directory               "/var/named";   //"Working" directory

dump-file               "data/cache_dump.db";

statistics-file         "data/named_stats.txt";

memstatistics-file      "data/named_mem_stats.txt";

listen-on port 53       { 192.168.100.110; };

allow-query             { 192.168.100.0/24; };

allow-query-cache       { 192.168.100.0/24; };

recursion yes;

};

logging

[root@ftp named]# mv named.localhost linuxfan.cn.zone

[root@ftp named]# vi linuxfan.cn.zone   ##正向解析配置文件
