FreeBSD网站平台建设全过程—安装配置ftp服务器

本文根据网上流行的一篇文章整理改编而成,并修正了原文的一些小错误。

  由于为每一个需要使用ftp服务的用户建立系统帐户会影响系统的安全,所以我们使用数据库用户进行ftp用户验证。

  系统组成:

  Proftpd1.2.7

  proftpd-mod-quotatab-1.2.4

  mysql3.23

  因为ports里没有proftpd-mod-quotatab-1.2.4模块,我们下载源代码安装。

  下载源代码包:(必须下载相同版本的源代码包)

  到 http://www.proftpd.org 或 ftp://ftp.servus.at/ProFTPD/distrib/source/proftpd-1.2.7.tar.gz

  去下载proftpd-1.2.7.tar.gz。

  到 http://www.castaglia.org/proftpd/ 去下载proftpd-mod-quotatab-1.2.4.tar.gz。(1.2.5 版本的mod_quotatab是用在1.2.8rc1上的)

  用ftp将它们上传到/home/ylf/app目录。

  然后解压缩源代码包:

  # cd /home/ylf/app

  # tar zxvf proftpd-1.2.7.tar.gz

  # tar zxvf proftpd-mod-quotatab-1.2.4.tar.gz

  进入mod-quotatab目录

  # cd mod_quotatab

  把mod_quotatab中的文件拷贝到proftpd 中的modules 目录中

  # cp * ../proftpd-1.2.7/modules

  在开始运行configure之前,我们要先改动一个文件

  进入 proftpd-1.2.7/contrib 目录

  # cd /home/ylf/app/proftpd-1.2.7/contrib

  修改 mod_sql_mysql.c

  # vi mod_sql_mysql.c

  找到#include 把他改为你的实际路径,这里是:

  #include

  然后编译安装:

  # cd /home/ylf/app/proftpd-1.2.7

  #./configure --prefix=/usr/local/proftpd --with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql --with-includes=/usr/local/include/mysql --with-libraries=/usr/local/lib/mysql

  # make

  # make install

  进入到proftpd配置文件所在目录

  # cd /usr/local/proftpd/etc

  备份原配置文件

  # mv proftpd.conf proftpd.conf.bak

  然后编辑新的配置文件proftpd.conf

  # vi proftpd.conf

  我的proftpd.conf内容如下:

  # This is a basic ProFTPD configuration file (rename it to

  # 'proftpd.conf' for actual use. It establishes a single server

  # and a single anonymous login. It assumes that you have a user/group

  # "nobody" and "ftp" for normal operation and anon.

  ServerName "ftpx.3322.org"

  ServerType standalone

  DefaultServer on

  # 用户登陆时不显示ftp服务器版本信息

  ServerIdent off

  # Port 21 is the standard FTP port.

  Port 21

  # Umask 022 is a good standard umask to prevent new dirs and files

  # from being group and world writable.

  Umask 022

  MaxLoginAttempts 3

  TimeoutLogin 120

  TimeoutIdle 600

  TimeoutNoTransfer 900

  TimeoutStalled 3600

  MaxClients 100

  # 设置每台主机最多并发连接数

  MaxClientsPerHost 3

  AllowOverwrite no

  AllowStoreRestart on

  UseReverseDNS off

  # 设置如果shell为空时允许用户登录

  RequireValidShell off

  # 将用户限制在自己的主目录下

  DefaultRoot ~ ftpusers

  DefaultRoot ~ FTPGRP

  # To prevent DoS attacks, set the maximum number of child processes

  # to 30. If you need to allow more than 30 concurrent connections

  # at once, simply increase this value. Note that this ONLY works

  # in standalone mode, in inetd mode you should use an inetd server

  # that allows you to limit maximum number of processes per service

  # (such as xinetd).

  MaxInstances 30

  # Set the user and group under which the server will run.

  User FTPUSR

  Group FTPGRP

  # Normally, we want files to be overwriteable.

  AllowOverwrite on

  # A basic anonymous configuration, no upload directories.

  # 匿名登录设置。匿名用户目录为/ftp

  User ftp

  Group ftpusers

  # We want clients to be able to login with "anonymous" as well as "ftp"

  UserAlias anonymous ftp

  # Limit the maximum number of anonymous logins

  MaxClients 10

  # We want 'welcome.msg' displayed at login, and '.message' displayed

  # in each newly chdired directory.

  DisplayLogin welcome.msg

  DisplayFirstChdir .message

  # Limit WRITE everywhere in the anonymous chroot

  #

  # DenyAll

  #

  # 数据库联接的信息,FTP是数据库名,localhost是主机名,root是连接数据库的用户名,#123456是密码

  #(如果没有密码留空)

  SQLConnectInfo FTP@localhost root 123456

  # 数据库认证的类型

  SQLAuthTypes Backend Plaintext

  # 指定用来做用户认证的表的有关信息。("FTPUSERS"和"FTPGRPS"是数据表名字,等一会

  # 在下面建立)

  SQLUserInfo FTPUSERS userid passwd uid gid homedir shell

  SQLGroupInfo FTPGRPS groupname gid members

  # 数据库的鉴别

  SQLAuthenticate users groups usersetfast groupsetfast

  # 如果home目录不存在,则系统会根据它的home项新建一个目录

  SQLHomedirOnDemand on

  # 启用磁盘限额

  QuotaDirectoryTally on

  # 磁盘限额单位 b"|"Kb"|"Mb"|"Gb"

  QuotaDisplayUnits "Kb"

  QuotaEngine on

  # 磁盘限额日志记录

  QuotaLog "/var/log"

  # 打开磁盘限额信息,当登陆FTP帐户后,使用命令 "quote SITE QUOTA" 后可显示当前用#户的磁盘限额

  QuotaShowQuotas on

  # SQL调用语句,不用修改

  SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avail, bytes_xfer_avail,files_in_avail, files_out_avail, files_xfer_avail FROM quotalimits WHERE name = '%{0}' AND quota_type = '%{1}'"

  SQLNamedQuery get-quota-tally SELECT "name, quota_type, bytes_in_used, bytes_out_used, bytes_xfer_used, files_in_used, files_out_used, files_xfer_used FROM quotatallies WHERE name = '%{0}' AND quota_type = '%{1}'"

  SQLNamedQuery update-quota-tally UPDATE "bytes_in_used = bytes_in_used + %{0}, bytes_out_used = bytes_out_used + %{1}, bytes_xfer_used = bytes_xfer_used + %{2}, files_in_used = files_in_used + %{3}, files_out_used = files_out_used + %{4}, files_xfer_used = files_xfer_used + %{5} WHERE name = '%{6}' AND quota_type = '%{7}'" quotatallies

  SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" quotatallies

  QuotaLimitTable sql:/get-quota-limit

  QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally

  下面为ftp用户建立相应的数据库和表

  进入mysql数据库命令状态:

  # mysql ?p

  提示输入密码

  建立数据库FTP(注意大小写和每句话后面的“;”)

  CREATE DATABASE FTP;

  然后在这个数据库中建立一个用户表FTPUSERS,这个表是必须的:

  use FTP;

  create table FTPUSERS (

  userid TEXT NOT NULL,

  passwd TEXT NOT NULL,

  uid INT NOT NULL,

  gid INT NOT NULL,

  homedir TEXT,

  shell TEXT

  );

  此表格是为了用户认证所需要的,其中userid、passwd是必不可少的,userid是用做FTP服务的用户名;passwd是指此用户的密码; uid是系统用户的ID,也就是所映射的系统用户;gid是所属系统组的ID;homedir是该用户所在的HOME目录;shell可以为该用户指定相 应的shell。当然你可以建立更多的字段,例
