环境:Linux操作系统
前提:以经安装VSFTPD、MySQL、PAM_MySQL
1、添加VSFTPD用户
[root@xxx]#useradd ftpguest
当虚拟用户登录后,所在的位置为vsftpguest的自家目录/home/vsftpguest。如果要让虚拟用户登录到/var/ftp等其他目录,修改vsftpguest的自家目录即可。
2、建立虚拟用户数据库
mysql>create database ftpuser;
mysql>use ftpuser;
mysql>create table users(name char(20), passwd char(20));
mysql>insert into users
->values ('ftp', 'ftp');
mysql>quit
3、为ftpguest设置数据库读取权限
mysql>grant select on ftpuser.users to vsftpguest@localhost identified by 'you_password';
mysql>quit
4、配置VSFTPD,使其使用虚拟用户登录
/etc/vsftpd/vsftpd.conf
添加:
chroot_local_user=YES
chroot_list_enable=YES
5、为VSFTPD添加授权
/etc/pam.d/vsftpd
auth required pam_mysql.o user=vsftpguest passwd=you_password host=localhost db=ftpuser table=users usercolumn=name passwdcolumn=passwd crypt=0
account required pam_mysql.o user=vsftpguest passwd=you_password host=localhost db=ftpuser table=users usercolumn=name passwdcolumn=passwd crypt=0
6、重启VSFTPD
[root@xxx]#service vsftpd restart
注:更改/etc/pam.d/vsftpd时,删除原内容,只存在以上内容。
