<p><FONT class=normalfont><B><font color=blue>使用linux的Proftpd创建FTP服务器时的一些高级设置(分权管理,限制删除等)</font></B></FONT><BR><FONT class=smallfont color=#ff9900>2004-04-23 15:18 pm</FONT><BR><FONT class=normalfont>作者:作者<br>来自:Linux知识宝库<br>联系方式:无名<br><br>1:<br>
用 root 登入<br>
cd /home<br>
ls -al<br>
*查看 ftp 子目录的属性和 user, group所属,如果显示是drwxr-xr-x 7 ftp root 4096 12 25 00:40 ftp的话,很明显,子目录ftp的 user和group分别是 ftp, root.那么我们就要改变子目录的所属<br>
<br>
2:<br>
我们还需要追加一个group(member作为VIP会员的group)<br>
命令: groupadd member<br>
<br>
3:<br>
我们要增加一个FTP管理者账号,定为<br>
superftp.此账号在FTP的使用中,具有ftp子目录内的最大权限.<br>
命令: useradd -g member -d /home/ftp superftp<br>
接下来我们给superftp设置密码<br>
命令: passwd superftp<br>
<br>
4:<br>
接下来我们需要改变子目录ftp的用户所有者<br>
命令: chown superftp ftp ,用在 /home/ftp 中制作 上传,下载专用子目录<br>
<br>
5:<br>
在这里我们假设/home/ftp/upuser: 用户可以上传文件,制作子目录,并<br>
删除自己上传的东西。但是其他人上传的东西无法删除。<br>
/home/ftp/downuser: 用户可以阅览(list),下载里<br>
面的文件。但是没有删除权限,也没有上传权限。此子目录的用<br>
途是斑竹将upuser/子目录中的经典文件装移到这个子目录里<br>
面,永久保存。<br>
注:superftp 可以对 这两个子目录进行任意操作,包括上<br>
传,删除。<br>
<br>
6:<br>
我们按照我们的构思打下面命令<br>
cd /home/ftp<br>
mkdir upuser<br>
mkdir downuser<br>
<br>
7:<br>
我们建立好这二个文件夹后,接下来我们要做的就是改变子目录 upuser 和<br>
downuser的所有者<br>
命令: chgrp -R member upuser<br>
chown -R superftp upuser<br>
chgrp -R member downuser<br>
chown -R superftp downuser<br>
-R 表示包括当前子目录下的所有子目录和文件<br>
修改chmod<br>
命令:chmod 755 ftp<br>
cd ftp<br>
chmod 755 downuser<br>
chmod 775 upuser<br>
<br>
8:<br>
检查一遍所有的步骤是否正确完成了.最后在特权模式下输入命令<br>
<br>
/etc/init.d/proftpd restart (重新启动proftpd, 使设置生效)<br>
<br>
9:<br>
试试吧,就这么多.有问题跟着贴帖.<br>
以上配置是需要你们安装好proftpd的情况下才能使用的,安装wu-ftp的朋友 赶快来试试proftpd吧.<br>
<br>
<br>
<br>
<br>
其实比较好的办法是,使用proftp+mysql,使系统用户与ftp用户脱离,然后再用<br>
<limit stor read mkd><br>
AllowAll<br>
</limit><br>
<limit write dele rmd><br>
DenyAll<br>
AllowUser upload<br>
</limit><br>
设置比较好,我就是这样干的,上面允许所有用户上传,但是只允许upload这个用户删除和更名操作。<br>
<br>
<br>
千万别把rm -rf ./*写成了rm -rf /*<br>
