安装配置一个proftpd的实例

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.

case "$1" in 
        start) 
                echo -n "Starting proftpd: " 
                daemon proftpd $OPTIONS 
                echo 
                touch /var/lock/subsys/proftpd

                if [ $? = 0 ]; then 
                        if [ $# -gt 1 ]; then 
                                shift 
                                echo -n "Suspending with '$*' " 
                                ftpshut $* 
                        else 
                                echo -n "Suspending NOW " 
                                ftpshut now "Maintanance in progress" 
                        fi 
                else 
                        echo -n "No way to suspend " 
                fi 
                echo 
                ;; 
        resume) 
                if [ -f /etc/shutmsg ]; then 
                        echo -n "Allowing sessions again "

                hash ftpshut 
                if [ $? = 1 ]; then 
                        echo '}' 
                else 
                        echo '|suspend}' 
                        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 <Limit> 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, <VirtualHost> or <Anonymous> (i.e. using it in a <Directory> 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<limit>中用这个,可以禁止或者允许连接进来。但是,如果不在Server config,<VirtualHost> 

或者<Anonymous>中使用的话,他将失去效用,或者说被忽略掉(比如在<Directory>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<limit>段基本上应用来说就没有问题了。
