系统环境：centos6.0 64位 + Mysql5.5

1、安装Mysql——省略

2、安装pam-mysql（文章末尾有下载）

tar zxvf pam_mysql-0.6.2.tar.gz
cd pam_mysql-0.6.2
./configure --with-mysql=/usr/local/mysql
make;make install

3、创建数据库和授权

/usr/local/mysql/bin/mysql -uroot -p123456
create database vsftpd; 
use vsftpd 
create table users(name char(20), passwd char(20)); 
insert into users values('lihuipeng','123456'); 
grant select, insert, update on vsftpd to 'vsftpd'@localhost identified by 'vsftpd';
flush privileges;

4、安装Vsftpd

 yum -y install vsftpd

5、配置虚拟用户

 vi /etc/vsftpd/vsftpd.conf
 

listen=YES
connect_from_port_20=YES
ftpd_banner=Welcome to virtual FTP service.
anonymous_enable=NO
local_enable=YES
write_enable=NO
anon_upload_enable=NO
anon_mkdir_write_enable=NO
anon_other_write_enable=NO
chroot_local_user=YES
guest_enable=YES
guest_username=root                                    #虚拟用户映射的实体用户
pasv_min_port=30000
pasv_max_port=30999
pam_service_name=vsftpd.vu                       #Mysql认证机制
user_config_dir=/etc/vsftpd/virtual                 #虚拟用户权限配置
xferlog_enable=YES
xferlog_file=/var/log/vsftpd.log
hide_file=.*

PS：建议不要用root，另外建立一个实体用户做映射

Mysql认证机制

 vi /etc/pam.d/vsftpd.vu
 

auth required /lib/security/pam_mysql.so user=vsftpd passwd=vsftpd host=localhost db=vsftpd table=users usercolumn=name passwdcolumn=passwd crypt=0
account required /lib/security/pam_mysql.so user=vsftpd passwd=vsftpd host=localhost db=vsftpd table=users usercolumn=name passwdcolumn=passwd crypt=0

虚拟用户权限配置

mkdir /etc/vsftpd/virtual
vi lihuipeng            #每个虚拟用户（Mysql创建的用户）对应一个权限文件 

anon_world_readable_only=NO
write_enable=YES
anon_mkdir_write_enable=YES
anon_upload_enable=YES
anon_other_write_enable=YES
local_root=/

虚拟用户权限常用有以下三种（上面我用的是管理员权限）：

 

[anvycn]仅仅允许下载

anon_world_readable_only=NO
local_root=/usr/local/apache/htdocs/anvy_test/

[dym529]允许建立，修改，但是不允许删除

anon_world_readable_only=NO
write_enable=YES
anon_mkdir_write_enable=YES
anon_upload_enable=YES
local_root=/usr/local/apache/htdocs/dym_test/

[admin]全部权限

anon_world_readable_only=NO
write_enable=YES
anon_mkdir_write_enable=YES
anon_upload_enable=YES
anon_other_write_enable=YES
local_root=/usr/local/apache/htdocs/

6、重启服务

service vsftpd restart
