2. Install mysql, skip it, you can view the previous document;

3. Install pam-mysql, dependent on pam-devel package;

[root@WebA-136 ~]#tar xf pam_mysql-0.7RC1.tar.gz

[root@WebA-136 ~]#yum install pam-devel

[root@WebA-136 ~]#./ configure --with-mysql=/usr/local/mysql --with-openssl

[root@WebA-136 ~]#make && make install

[root@WebA-136 ~]#less README

[root@WebA-136 ~]#vim /etc/pam.d/vsftpd.mysql

[root@WebA-136 ~]#cat /etc/pam.d/vsftpd.mysql

[root@WebA-136 ~]#auth required /lib/security/pam_mysql.so user=vsftpd passwd=123456 host=192.168.146.136 db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=3 md5=yes

[root@WebA-136 ~]#account required /lib/security/pam_mysql.so user=vsftpd passwd=123456 host=192.168.146.136 db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=3 md5=yes

reconfigure database

create database vsftp;

grant selcet on vsftp.* to vsftpd@192.168.146.136 identified by '123456';

create tables

create table users(

id smallint auto_increment not null,

name char(20) binary not null,

password char(48) binary not null,

primary key(id))

;

View table structure

desc users;

You also need to insert virtual users here

INSERT INTO users(name,password)VALUES('tom',md5(123456)),('jack',md5(123456));

4. Modify the vsftpd.conf configuration file for mysql authentication

First create user

useradd -s /sbin/nologin -d /var/ftp-test vsftp

chmod go+rx /var/ftp-test

Make sure the following options are turned on in vsftpd.conf

[root@WebA-136 ~]#vim /etc/vsftpd/vsftpd.conf

anonymous_enable=YES

local_enable=YES

write_enable=YES

anon_upload_enable=NO

anon_mkdir_write_enable=NO

chroot_local_user=YES

Add the following options

guest_enable=YES

guest_username=vsftpd#####All virtual users must map to a specified user.

listen=YES

pam_service_name=vsftpd.mysql

Note: Different access permission settings can be implemented according to different virtual users.

Added in vsftpd.conf

user_config_dir=/etc/vsftpd/test

Add a file with the same name as the virtual user to/etc/vsftpd/test directory

cd /etc/vsftpd/test

vim tom

anon_upload_enable=YES

anon_mkdir_write_enable=YES

vim jack

anon_upload_enable=NO

anon_mkdir_write_enable=NO
