Password: 
Enter it again: 

• 编辑配置文件, 指定 用户数据库

[root@node10009 pureftpd]# ./bin/pure-pw mkdb
[root@node10009 pureftpd]# vim etc/pure-ftpd.conf 
    ...
     PureDB                       /opt/app/pureftpd/etc/pureftpd.pdb
    ...

• 添加测试文件, 并设置好目录权限

[root@node10009 pureftpd]# echo 'hello' > /opt/ftp/share/a.txt 
[root@node10009 pureftpd]# chown -R pureftp. /opt/ftp/share/

• 启动服务

[root@node10009 pureftpd]# ./sbin/pure-ftpd /opt/app/pureftpd/etc/pure-ftpd.conf 
[root@node10009 pureftpd]# ss -tan | grep 21
LISTEN     0      9            *:21                       *:*                  
LISTEN     0      9           :::21                      :::*                  
[root@node10009 pureftpd]#

3. 配置使用MySQL 登陆

3.1 MySQL 相关设置

• 创建用于存储pure-ftp 用户 的数据库和数据表

MySQL [(none)] > CREATE  database pureftp DEFAULT CHARACTER SET=utf8;
Query OK, 1 row affected (0.00 sec)

MySQL [(none)] > use pureftp
MySQL [pureftp] > 

CREATE TABLE `ftpuser` (
    `user` VARCHAR(20) NOT NULL,
    `password` VARCHAR(255) NOT NULL,
    `uid` INT NOT NULL default '-1',
    `gid` INT NOT NULL default '-1',
    `dir` VARCHAR(255) NOT NULL,
    `status` TINYINT NOT NULL DEFAULT '0',
    PRIMARY KEY(User)
)ENGINE=InnoDB DEFAULT CHARACTER SET=utf8;

Query OK, 0 rows affected (0.02 sec)

• 创建 pureftpd 连接数据库的用户.

MySQL [pureftp] > GRANT ALL ON pureftp.* TO 'pureftp'@'127.0.0.1' IDENTIFIED BY 'pureftp';
Query OK, 0 rows affected, 1 warning (0.01 sec)

MySQL [pureftp] > FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.02 sec)

• 插入用户数据

MySQL [pureftp] > INSERT INTO `ftpuser`(`user`, `password`, `uid`, `gid`, `dir`,`status`) VALUES('user1', MD5('123'), 958,, 2001
Query OK, 1 row affected (0.01 sec)

MySQL [pureftp] > SELECT * FROM `ftpuser`;
+-------+----------------------------------+-----+-------+----------------+--------+
| user  | password                         | uid | gid   | dir            | status |
+-------+----------------------------------+-----+-------+----------------+--------+
| user1 | 202cb962ac59075b964b07152d234b70 | 958 | 2001 | /opt/ftp/share |      1 |
+-------+----------------------------------+-----+-------+----------------+--------+
1 row in set (0.01 sec)

3.2 修改配置文件

• 修改主配置文件 /opt/app/pureftp/etc/pure-ftpd.conf

## 1. 注释 PureDB 项
# PureDB                       /opt/app/pureftpd/etc/pureftpd.pdb
...
## 2. 设置 MySQLConfigFile 
 MySQLConfigFile              /opt/app/pureftp/etc/pureftpd-mysql.conf

• /opt/app/pureftp/etc/pureftp-mysql.conf

MYSQLServer     127.0.0.1
MYSQLPort       3306
MYSQLSocket     /tmp/mysql.sock
MySQLDatabase   pureftp
MYSQLUser       pureftp
MYSQLPassword   pureftp
MySQLCrypt      md5 

MYSQLGetPW SELECT password FROM ftpuser WHERE user ='\L' AND status=1
MYSQLGetUID SELECT uid FROM ftpuser WHERE user ='\L'  AND status=1
MYSQLGetGID SELECT gid FROM ftpuser WHERE user ='\L'  AND status=1
MYSQLGetDir SELECT dir FROM ftpuser WHERE user = '\L' AND status=1
