RHEL 5 vsftp使用mysql 存储虚拟用户：
ftp Server IP
：
10.0.0
.252/8
试验步骤：
1．
为了装包方便搞定
yum
服务
（略）
2．
安装
MYSQL
服务
[root@Bhanv ~]# yum install mysql-server �Cy
Installing: mysql-server ######################### [1/1]
Installed: mysql-server.i386 0: 5.0.45 -7.el5
Complete!
3.
安装
VSFTP
服务所需的软件包
[root@Bhanv ~]# yum install vsftpd -y
Installing: vsftpd ######################### [1/1]
Installed: vsftpd.i386 0: 2.0.5 -12.el5
Complete!
4.
默认
RHEL5
不支持
vsftp
与
mysql
连接，需要下载编译所支持的模括。
[root@Bhanv~]#wget http://downloads.sourceforge.net/project/pam-mysql/pam-mysql/0.7RC1/pam_mysql-0.7RC1.tar.gz?use_mirror=nchc
[root@Bhanv ~]# ll pam_mysql-0.7RC1.tar.gz
-rw-r--r-- 1 root root 335240 2006-01-09 pam_mysql-0.7RC1.tar.gz
[root@Bhanv ~]# yum install gcc gcc-c++ pam-devel mysql-devel �Cy
[root@Bhanv ~]# tar zxf pam_mysql-0.7RC1.tar.gz -C /tmp/
[root@Bhanv ~]# cd /tmp/pam_mysql-0.7RC1/
[root@Bhanv pam_mysql-0.7RC1]# ./configure
[root@Bhanv pam_mysql-0.7RC1]# make;make install
[root@Bhanv pam_mysql-0.7RC1]# ll /lib/security/pam_mysql.so
-rwxr-xr-x 1 root root 93416 04-08 13:14 /lib/security/pam_mysql.so
5
．创建虚拟用户对应的系统用户
[root@Bhanv pam_mysql-0.7RC1]# useradd -d /home/virtual -s /sbin/nologin virtual
6
．创建存储虚拟用户的数据库和表。
#mysql �Cu root �Cp
mysql>create database ftpdb
mysql>use ftpdb
mysql>create table ftpusers(name char(20),password char(20))
mysql> insert into ftpusers(name,password) values ('pei','pei')
mysql> insert into ftpusers(name,password) values ('huan','huan')
mysql>grant select on ftpdb.ftpusers to virtual@localhost identified by 'Bhanv'
7
．修改
vsftp
主配置文件：
[root@Bhanv /]# vi /etc/vsftpd/vsftpd.conf
pam_service_name=vsftpd.virtual
guest_enable=YES
guest_username=virtual
8
．建立
pam
认证文件
[root@Bhanv /]# vi /etc/pam.d/vsftpd.virtual
auth required /lib/security/pam_mysql.so user=virtual passwd=Bhanv host=localhost db=ftpdb table=ftpusers usercolumn=name passwdcolumn=password crpty=0
account required /lib/security/pam_mysql.so user=virtual passwd=Bhanv host=localhost db=ftpdb table=ftpusers usercolumn=name passwdcolumn=password crpty=0
注意：
crypt= n
crypt=0:
明文密码
crypt=1:
使用
crpyt()
函数
(
对应
SQL
数据里的
encrypt()
，
encrypt()
随机产生
salt)
crypt=2:
使用
MYSQL
中的
password()
函数加密
crypt=3
：表示使用
md5
的散列方式
测试：
[root@Bhanv ~]# ftp localhost
Connected to localhost.localdomain.
