ProFTPd详细安装配置文档

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.

                echo -n "Starting proftpd: "

                                ftpshut $*

                                ftpshut now "Maintanance in progress"
                        fi
                else
                        echo -n "No way to suspend "
                fi
                echo

                else

                        echo 'suspend accepts additional arguments which are passed to ftpshut(8)'
                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 to this pseudo-command can be used to allow or deny initial connection or login to the context. It has no 

effect, and is ignored, when used in a context other than server config, or (i.e. using it in a context 

is meaningless). 

翻译下：最后，有一个用来限制登陆的特殊命令，就是LOGIN。在中用这个，可以禁止或者允许连接进来。但是，如果不在Server config， 

或者中使用的话，他将失去效用，或者说被忽略掉（比如在中使用就是无效的）。

proftpd感觉还是比vsftp功能配置上好用一点，主要掌握好段基本上应用来说就没有问题了。
