启动proftp

/etc/init.d/proftp start

在ftp库中添加如下语句

INSERT INTO ftpuser (id, userid, passwd, uid, gid, homedir, shell, count, accessed, modified) VALUES ('', 'jastme', ENCRYPT('jastme'), 2001, 2001, '/website/jastme', '/sbin/nologin', 0, now(), now());

创建了一个叫jastme的用户，密码为jastme，用户根目录为/website/jastme

本地测试

ftp 127.0.0.1

输入用户名和密码，OK  ftp会自动新建用户的根目录。
