CentOS7 +vsftpd+mysql （三）之 MySql 虚用户模式

上篇中通过文本文件用户列表方式对FTP用户进行用户管理很不方便，接下来我们用上数据库存方式，实现用户管理。

一、安装Mysql

[[email protected] vsftpd]# yum install wget -y
[[email protected] local]# cd /usr/local/src
[[email protected] src]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

[[email protected] src]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
[[email protected] src]# yum install mysql-community-server

[[email protected] src]# yum install -y  mysql

[[email protected] src]# rpm -qa |grep mysql
mysql-community-release-el7-5.noarch
mysql-community-common-5.6.37-2.el7.x86_64
mysql-community-client-5.6.37-2.el7.x86_64
mysql-community-libs-5.6.37-2.el7.x86_64
mysql-community-devel-5.6.37-2.el7.x86_64
mysql-community-server-5.6.37-2.el7.x86_64

[[email protected] src]# find / -name "mysql"
/etc/logrotate.d/mysql
/etc/selinux/targeted/active/modules/100/mysql
/var/lib/mysql
/usr/bin/mysql
/usr/lib64/mysql
/usr/share/mysql
/usr/include/mysql
/usr/include/mysql/mysql

[[email protected] src]# systemctl start mysqld

 二、设置mysql与创建用户数据库

[[email protected] src]# mysql -uroot -p

#新装没有密码，直接回车
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
+--------------------+
3 rows in set (0.00 sec)
mysql> set password for ‘root‘@‘localhost‘ =password(‘1234Test.,‘);
mysql> create database vftpuser;
Query OK, 1 row affected (0.00 sec)

mysql> use vftpuser;
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 (0.34 sec)

mysql> insert into users (name,password ) values (‘showmuftp‘,password(‘111111‘));
Query OK, 1 row affected (0.00 sec)

mysql> insert into users (name,password ) values (‘showmuweb‘,password(‘222222‘));
Query OK, 1 row affected (0.01 sec)

mysql> insert into users (name,password ) values (‘showmuguest‘,password(‘333333‘));
Query OK, 1 row affected (0.01 sec)
mysql> \q
Bye

[[email protected] src]# mysql -uroot -p  

mysql> use vftpuser;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

mysql> SELECT id,name,password FROM users;
+----+-------------+-------------------------------------------+
| id | name        | password                                  |
+----+-------------+-------------------------------------------+
|  1 | showmuftp   | *FD571203974BA9AFE270FE62151AE967ECA5E0AA |
|  2 | showmuweb   | *A0C1808B1A47CECD5C161FEE647F5427F4EB6F98 |
|  3 | showmuguest | *DF2FAF9AD979B357C54A6723638197DDB913E1C8 |
+----+-------------+-------------------------------------------+
3 rows in set (0.00 sec)
mysql> \q
Bye

 三、安装pam_mysql-0.7RC1

[[email protected] src]# yum install pam-devel
[[email protected] src]# wget https://nchc.dl.sourceforge.net/project/pam-mysql/pam-mysql/0.7RC1/pam_mysql-0.7RC1.tar.gz
[[email protected] src]# tar -zxvf pam_mysql-0.7RC1.tar.gz  
[[email protected] src]# cd pam_mysql-0.7RC1
[[email protected] src]# yum install -y make gcc-c++ cmake bison-devel ncurses-devel gcc autoconf automake zlib* fiex* libxml*

[[email protected] pam_mysql-0.7RC1]# ./configure --with-mysql=/usr --with-pam-mods-dir=/lib64/security/

[[email protected] pam_mysql-0.7RC1]# make&&make install

 四、设置vsftpd

[[email protected] security]# vim /etc/pam.d/vsftpd.mysqldb
auth required /lib64/security/pam_mysql.so user=root passwd=1234Test., host=localhost  db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=2
account required /lib64/security/pam_mysql.so user=root passwd=1234Test., host=localhost db=vsftpd table=users usercolumn=name passwdcolumn=password crypt=2

[[email protected] pam_mysql-0.7RC1]# vim /etc/vsftpd/vsftpd.conf
[[email protected] pam_mysql-0.7RC1]# cd /etc/vsftpd
[[email protected] vsftpd]# ls
ftpusers   vftpuser_conf  vftpusers.txt  vsftpd.conf_2017-10-05  vsftpd.conf.rpmsave
user_list  vftpusers.db   vsftpd.conf    vsftpd_conf_migrate.sh


[[email protected] vsftpd]# grep -Ev ‘(^#\s.*|^#|^$)‘ vsftpd.conf
anonymous_enable=YES
anon_mkdir_write_enable=YES
anon_root=/www/ftp/pub
local_root=/www/ftp/pub
local_enable=YES
write_enable=YES
local_umask=022
anon_upload_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
listen=NO
listen_ipv6=YES
pam_service_name=vsftpd.mysqldb
userlist_enable=YES
tcp_wrappers=YES
guest_enable=YES
guest_username=vftpuser
user_config_dir=/etc/vsftpd/vftpuser_conf
allow_writeable_chroot=YES

[[email protected] vsftpd]# systemctl restart vsftpd
[[email protected] vsftpd]# systemctl status vsftpd
