说轻松，配置起来可真不轻松，不过幸好有google，如果靠百度，估计我怎么死的都不知道~ 废话不多说，开始写流程

平台：ubuntu10.04 server
前景重现：已经安装好mysql，安装ispcp正式版、分支版本都失败，决定独立安装

清理垃圾：

apt-get remove preftpd

rm -rf /etc/proftpd

开始安装（mod_mysql是我后来看配置文件才发现要装~）

apt-get install proftpd proftpd-mod-mysql

选择   standalone

vi /etf/proftpd/proftpd.conf

依照如下修改设置

UseIPv6                         off
Include /etc/proftpd/sql.conf             #前面的#删掉

创建ftp权限

groupadd -g 2001 ftpgroup
useradd -u 2001 -s /bin/false -d /bin/null -c “proftpd user” -g ftpgroup ftpuser

mysql创建proftpd库，最好用phpmyadmin

先创建用户，用户名proftpd，密码自定义一个或者随机都可以，然后建立ftp库

create database ftp;
GRANT SELECT, INSERT, UPDATE, DELETE ON ftp.* TO ‘proftpd’@'localhost’ IDENTIFIED BY ‘password’;
GRANT SELECT, INSERT, UPDATE, DELETE ON ftp.* TO ‘proftpd’@'localhost.localdomain’ IDENTIFIED BY ‘password’;
FLUSH PRIVILEGES;

点ftp库的sql指令选项卡，（命令行操作时，输入 use ftp;）

CREATE TABLE ftpgroup (
groupname varchar(16) NOT NULL default ”,
gid smallint(6) NOT NULL default ’5500′,
members varchar(16) NOT NULL default ”,
KEY groupname (groupname)
) COMMENT=’ProFTP group table’;

CREATE TABLE ftpquotalimits (
name varchar(30) default NULL,
quota_type enum(‘user’,'group’,'class’,'all’) NOT NULL default ‘user’,
per_session enum(‘false’,'true’) NOT NULL default ‘false’,
limit_type enum(‘soft’,'hard’) NOT NULL default ‘soft’,
bytes_in_avail int(10) unsigned NOT NULL default ’0′,
bytes_out_avail int(10) unsigned NOT NULL default ’0′,
bytes_xfer_avail int(10) unsigned NOT NULL default ’0′,
files_in_avail int(10) unsigned NOT NULL default ’0′,
files_out_avail int(10) unsigned NOT NULL default ’0′,
files_xfer_avail int(10) unsigned NOT NULL default ’0′
);

CREATE TABLE ftpquotatallies (
name varchar(30) NOT NULL default ”,
quota_type enum(‘user’,'group’,'class’,'all’) NOT NULL default ‘user’,
bytes_in_used int(10) unsigned NOT NULL default ’0′,
bytes_out_used int(10) unsigned NOT NULL default ’0′,
bytes_xfer_used int(10) unsigned NOT NULL default ’0′,
files_in_used int(10) unsigned NOT NULL default ’0′,
files_out_used int(10) unsigned NOT NULL default ’0′,
files_xfer_used int(10) unsigned NOT NULL default ’0′
);

CREATE TABLE ftpuser (
id int(10) unsigned NOT NULL auto_increment,
userid varchar(32) NOT NULL default ”,
passwd varchar(32) NOT NULL default ”,
uid smallint(6) NOT NULL default ’5500′,
gid smallint(6) NOT NULL default ’5500′,
homedir varchar(255) NOT NULL default ”,
shell varchar(16) NOT NULL default ‘/sbin/nologin’,
count int(11) NOT NULL default ’0′,
accessed datetime NOT NULL default ’0000-00-00 00:00:00′,
modified datetime NOT NULL default ’0000-00-00 00:00:00′,
PRIMARY KEY (id),
UNIQUE KEY userid (userid)
) COMMENT=’ProFTP user table’;

quit;

修改刚刚激活的sql.conf

vi /etc/proftpd/modules.conf

wq!

文件编辑完了，添加个用户在ftpuser表里，填写用户名、密码、homedir的位置就可以了

然后重启服务
service proftpd restart  (或/etc/init.d/proftpd restart)
