apache ftp server的简单入门(数据库验证)

apache的简单校验分为两种，一直是前面提到的properties的校验，具体参考:apache ftp server的简单入门(properties验证)

今天来说一种数据库的校验，这种方式在项目中更加常用：

具体步骤如下：

　　第一步：下载解压（我在window上演示，linux上就启动命令由bat的命令换成sh命令即可，不会的自己百度，网上有很多资料）

　　第二步：进入%ftp-server%/res中修改一下数据库文件，并在数据库中创建对于的表 ftpd-db.sql

　　到这儿还没结束：

　　我是mysql演示，就在mysql中说：在mysql中创建一个数据库，暂定为ftpserver 并在库中创建上面那个权限认证表（我认为的），成功如下：

　　往表中添加允许登录ftp的用户，

INSERT INTO `ftpserver`.`ftp_user` (`userid`, `userpassword`, `homedirectory`, `enableflag`, `writepermission`, `idletime`, `uploadrate`, `downloadrate`, `maxloginnumber`, `maxloginperip`) VALUES ('admin', 'admin', 'D:/', '1', '0', '0', '0', '0', '0', '0');
INSERT INTO `ftpserver`.`ftp_user` (`userid`, `userpassword`, `homedirectory`, `enableflag`, `writepermission`, `idletime`, `uploadrate`, `downloadrate`, `maxloginnumber`, `maxloginperip`) VALUES ('huhy', '123456', './res/home', '1', '0', '0', '0', '0', '0', '0');

　　第三步，配置数据库文件，ftpd-mysql.xml -----------这是从ftpd-typical.xml cp 过来的，，为了不破坏原来的文件结构，即出错，只需要删除我自己创建的一个文件即可

　　ftpd-mysql.xml的文本信息　(把数据库连接信息改了就可以直接用)
