目的:
安装配置一个proftpd,达到以下要求
1 不允许匿名访问。
2 开放一个帐号,只有在upload目录有上传权限,可以续传,不能改名和删除。
操作:
0 切换到root帐户
[code:1:de92f96787] su root //输入root的密码。
[/code:1:de92f96787]
1 下载proftpd
地址:www.proftpd.org。这里我们下载了1.2.9版本
[code:1:de92f96787] wget
ftp://ftp.proftpd.org/distrib/source/proftpd-1.2.9.tar.gz
[/code:1:de92f96787]
2 安装proftpd
切换到下载目录,假设为/tmp/proftpd,然后
[code:1:de92f96787] tar zxvf proftpd-1.2.9.tar.gz
//解压
cd proftpd-1.2.9
./configure --prefix=/var/proftpd
--syscOnfdir=/etc //设置安装目录/var/proftpd,配置文件目录/etc
make
make install
[/code:1:de92f96787]
3 新建ftp专用帐号
就是上面目的中提到的那个专用帐号,这里以skate/skate(u/p)为例。
[code:1:de92f96787] groupadd skate
useradd skate -g skate -d /var/ftp
-s /sbin/nologin //设置/var/ftp目录为ftp的目录
passwd skate //设置skate用户的密码
mkdir /var/ftp/upload
chown skate.skate /var/ftp/upload
//设置upload目录skate用户可写
[/code:1:de92f96787]
4 设置proftpd
proftpd的配置文件就一个,就是/etc/proftpd.conf
[code:1:de92f96787] vi /etc/proftpd.conf
//打开proftpd.conf
[/code:1:de92f96787]
[code:1:de92f96787]

编辑完以后按Esc,然后输入:x保存。
5 启动服务
编辑一个启动脚本(这个是从网上copy的,不是我写的,感谢那个写这个脚本的人,很好用,thx)
[code:1:de92f96787] vi
/etc/rc.d/init.d/proftpd[/code:1:de92f96787]
[code:1:de92f96787]
#####脚本内容开始########
#!/bin/sh
#
# Startup script for ProFTPD
#
# chkconfig: 345 85 15
# description: ProFTPD is an enhanced FTP server with \
#
a focus toward simplicity, security, and ease of configuration.
\
#
It features a very Apache-like configuration syntax, \
#
and a highly customizable server infrastructure, \
#
including support for multiple 'virtual' FTP servers, \
#
anonymous FTP, and permission-based directory visibility.

fi
exit 1
esac
if [ $# -gt 1 ]; then
shift
$0 $*
fi
exit 0
#######脚本结束#########
[/code:1:de92f96787]
按Esc,输入:x保存。
然后添加到系统服务并启动
[code:1:de92f96787]
chkconfig --add profptd
service proftpd start[/code:1:de92f96787]
以后可以用service proftpd restart来重起proftpd。
6 一点体会
看proftpd的文档翻译过的一句话:Finally, a special command is allowed which can
be used to control login access: LOGIN Connection or login
to
the server. Applying a
effect, and is ignored, when used in a context other than server
config,
is meaningless).
翻译下:最后,有一个用来限制登陆的特殊命令,就是LOGIN。在
或者
proftpd感觉还是比vsftp功能配置上好用一点,主要掌握好
