FTP服務系列之vsftpd+pam+mysql實現虛擬用戶認證

 vsftpd+pam+mysql

 

一、安裝所需要程序

1、事先安裝好開發環境和mysql數據庫;
# yum -y install mysql-server mysql-devel
# yum -y groupinstall "Development Tools" "Development Libraries"

2.安裝pam_mysql-0.7RC1
[root@localhost ~]# tar xf pam_mysql-0.7RC1.tar.gz
[root@localhost ~]# cd pam_mysql-0.7RC1
[root@localhost pam_mysql-0.7RC1]# ./configure --with-mysql=/usr --with-openssl
[root@localhost pam_mysql-0.7RC1]# make
[root@localhost pam_mysql-0.7RC1]# make install

編譯選項解釋：
--with-mysql=/usr            #mysql的安裝路徑
--with-openssl               #表示連接mysql數據庫時，可以實現加密的方式通信(可用可不用)

3.安裝vsftpd
# yum -y install vsftpd

二、創建虛擬用戶賬號

1.準備數據庫及相關表

首先請確保mysql服務已經正常啓動。而後，按需要建立存儲虛擬用戶的數據庫即可，這裏將其創建爲vsftpd數據庫。

mysql> create database vsftpd;

mysql> grant select on vsftpd.* to vsftpd@localhost identified by 'vsftpd';

mysql> grant select on vsftpd.* to [email protected] identified by 'vsftpd';

mysql> flush privileges;

mysql> use vsftpd;

mysql> create table users (

    -> id int AUTO_INCREMENT NOT NULL,

    -> name char(20) binary NOT NULL,

    -> password char(48) binary NOT NULL,

    -> primary key(id)

    -> );

2、添加測試的虛擬用戶

根據需要添加所需要的用戶，需要說明的是，這裏將其密碼採用明文格式存儲，原因是pam_mysql的password()函數與MySQL的password()函數可能會有所不同。

mysql> insert into users(name,password) values('tom','redhat');

mysql> insert into users(name,password) values('jerry','redhat');

詳細操作過程：

[root@localhost pam_mysql-0.7RC1]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> create database vsftpd;
Query OK, 1 row affected (0.12 sec)

mysql> use vsftpd;
Database changed
mysql> create table users (id int AUTO_INCREMENT NOT NULL,name char(20) binary NOT NULL,password char(48) binary NOT NULL,primary key(id));
Query OK, 0 rows affected (0.08 sec)

mysql> desc users;
+----------+----------+------+-----+---------+----------------+
| Field    | Type     | Null | Key | Default | Extra          |
+----------+----------+------+-----+---------+----------------+
| id       | int(11)  | NO   | PRI | NULL    | auto_increment |
| name     | char(20) | NO   |     | NULL    |                |
| password | char(48) | NO   |     | NULL    |                |
+----------+----------+------+-----+---------+----------------+
3 rows in set (0.03 sec)

mysql> grant select on vsftpd.* to vsftpd@localhost identified by 'vsftpd';
Query OK, 0 rows affected (0.04 sec)

mysql> grant select on vsftpd.* to [email protected] identified by 'vsftpd';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> insert into users(name,password) values('tom','redhat'),('jerry','redhat')
    -> ;
Query OK, 2 rows affected (0.01 sec)
Records: 2  Duplicates: 0  Warnings: 0

mysql> select * from users;
+----+-------+----------+
| id | name  | password |
+----+-------+----------+
|  1 | tom   | redhat   |
|  2 | jerry | redhat   |
+----+-------+----------+
2 rows in set (0.00 sec)

mysql> \q
Bye
