編輯proftpd.conf檔案

vi /usr/local/proftpd/etc/proftpd.conf

添加下面幾行參數

<Global>

SQLConnectInfo ftpusers@localhost:3306 root chen

創建資料庫與表

[mysql@linux mysql]$ echo "create database ftpusers" | mysql -uroot -pchen

[mysql@linux mysql]$ mysql -uroot -pchen ftpusers < ftpusers.sql

[mysql@linux mysql]$



再次啟動ProFTPD

/usr/local/proftpd/sbin/in.proftpd

這次使用MySQL用戶登錄Ftp Server

顯示230 User xxxxx logged in. ＭySQL認證成功

			

tar xvzf proftpd-version.tar.gz

cd proftpd-version

./configure --prefix=/usr/local/proftpd --with-modules=mod_ldap

make

make install



# tar zxvf mod_ldap-2.8.10.tar.gz



將mod_ldap-2.8.10目錄下的posixAccount-objectclass和posixGroup-objectclass

複製到OpenLDAP 的schema目錄下：



# cp mod_ldap-2.8.10/posix* /etc/openldap/schema/

# vi /etc/openldap/slapd.conf

修改OpenLDAP的配置檔案slapd.conf，將這兩個檔案包含到該檔案中：

include /etc/openldap/schema/posixAccount-objectclass

include /etc/openldap/schema/posixGroup-objectclass

重新啟動OpenLDAP：

# service ldap restart

Stopping slapd:                                            [  OK  ]

Starting slapd:                                            [  OK  ]



編輯proftpd.conf檔案

vi /usr/local/proftpd/etc/proftpd.conf

添加下面幾行參數



<Global>

LDAPServer localhost
LDAPDNInfo cn=your-dn,dc=horde,dc=net dnpass
LDAPDoAuth on "dc=users,dc=horde,dc=net"

</Global>



格式說明：

LDAPServer OpenLDAP伺服器
LDAPDNInfo cn=你的-dn,dc=區域名,dc=區域名 dn密碼
LDAPDoAuth on "dc=區域名,dc=區域名"

例子：

       <Global>

LDAPServer localhost

LDAPDNInfo cn=manager,dc=xuser,dc=net secret

LDAPDoAuth on dc=xuser,dc=net

</Global>



根據自己需要修改mod_ldap-2.8.10目錄中的group-ldif和user-ldif檔案，並將條目添加到OpenLDAP中：



# ldapadd -x -D "cn=manager,dc=xuser,dc=net" -w secret -f group-ldif

# ldapadd -x -D "cn=manager,dc=xuser,dc=net" -w secret -f user-ldif



顯示：adding new entry "cn=mygroup, dc=xuser, dc=net" 添加成功

使用ldapsearch查看記錄

# ldapsearch -x -b "dc=xuser,dc=net"



啟動ProFTPD：

/usr/local/proftpd/sbin/in.proftpd

使用OpenLDAP用戶登錄Ftp Server

顯示230 User xxxxx logged in. OpenLDAP認證成功



例：

[root@linux mod_ldap-2.8.10]# cat group-ldif

上面的用戶密碼是用crypt方式加密的密碼，密碼產生請看

使用PHP產生：

# cat des.php

<html>

<p>DES 密碼產生器</p>

<form method=post action=des.php>

<p>password:<input name=passwd type=text size=20></p>

<input type=submit value=submit>

</form>

<?

$enpw=crypt($passwd);

echo "password is: $enpw";

?>

使用perl產生：

perl -e 'print("userPassword: ".crypt("secret","salt")."\n");'

產生的DES密碼，同樣也可以用於OpenLDAP的管理員密碼

# vi /etc/openldap/slapd.conf

rootpw                {crypt}ijFYNcSNctBYg

Q：在本地ftp localhost輸入用戶名、密碼回車後。等很久才進入FTP Server

A：ftp 127.0.0.1



Q：在遠程伺服器上ftp ip輸入用戶名、密碼回車後。等很久才進入FTP Server

A：LDAPServer localhost 改為 LDAPServer 127.0.0.1



Q：[root@linux mod_ldap-2.8.10]# ftp 127.0.0.1

500 FTP server shut down (going down at Tue Dec 17 19:00:00 2002) -- please try again later.

ftp>

A：rm –rf /etc/shutmsg

Q：登錄Ftp Server 提示

530 Login incorrect.

Login failed.
我確認輸入的用戶、密碼決對正確

A：在登錄ProFTPD時加參數proftpd –d5 –n會輸出調試信息。你可以在其中

找到答案。如果在調試信息中找到這一行no such user 'xxxx'
可能是與MySQL/OpenLDAP連接有問題。

Q：我在網上看見很多介紹如何安裝ProFTPD文章,閲讀大量的How to，按How to一步一步做，從來沒有安裝成功過。
