全力打造多功能FreeBSD服务器

硬件：赛扬566、128MB内存、20GB硬盘9(/ /home /usr /var /tmp四个分区)，8029兼容网卡等等；
软件：最小安装的FreeBsd 4.7

还是按由浅到深的顺序来讲吧；

1、安装webmin:
# tar -zxvf webmin-version.tar.gz
# mv webmin-version /usr/local/webmin
# cd webmin
# chmod 755 setup.sh
# ./setup.sh
然后基本上一路回车就能搞定，不要说这些简单E文你也不懂啊：）

2、apache+mysql+php的安装；
需要的软件包：
httpd-2.0.43.tar.gz
mysql-3.23.53.tar.gz
php-4.3.2.tar.gz
假设这些软件包存放在/home/down目录下

a、安装Mysql
# pw groupadd mysql
# pw useradd mysql -g mysql -s /nonexitent
# tar -zxvf mysql-3.23.53.tar.gz
# mv mysql-3.23.53 mysql
# cd mysql
# ./configure --prefix=/usr/local/mysql
# make
# make install
# scripts/mysql_install_db
# chown -R root /usr/local/mysql
# chown -R mysql /usr/local/mysql/var
# chgrp -R mysql /usr/local/mysql
# cp support-files/my-medium.cnf /etc/my.cnf
# /usr/local/mysql/bin/safe_mysqld --user=mysql &
# echo "/usr/local/mysql/bin/safe_mysqld --user=mysql &" >> /etc/rc.local
# cd /usr/local/mysql/bin
# ./mysqladmin -u root -p password "your-password"

b、安装apache
# cd /home/down
# tar -zxvf httpd-2.0.43.tar.gz
# mv httpd-2.0.43 apache
# cd apache
# ./configure --prefix=/usr/local/apache --with-mysql=/usr/local/mysql --enable-shared=max --enable-module=so
# make
# make install
# mv /usr/local/apache/htdocs/index.html.en /usr/local/apache/htdocs/index.html
# /usr/local/apache/bin/apachectl start

c、安装php
# cd /home/down
# tar -zxvf php-4.3.0.tar.gz
# mv php-4.3.0 php
# cd php
# ./configure --prefix=/usr/local/php4 --with-mysql=/usr/local/mysql --with-apxs2=/usr/local/apache/bin/apxs
# make
# make install
# ee /usr/local/apache/conf/httpd.conf
在其中加上下面三行代码，就可以使apache支持php了，然后保存退出。
LoadModule php4_module modules/libphp4.so
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
然后在httpd.conf文件查找DirectoryIndex index.html，在它后面加上index.htm index.php。
到此apache+mysql+php已经配置完毕！！

3、Proftpd的安装，并使之与mysql整合
需要的软件包，存放在/home/down
proftpd-1.2.7.tar.gz
mod_sql-4.0.8.tar.gz
# cd /home/down
# tar –zxvf proftpd-1.2.7.tar.gz
# mv proftpd-1.2.7 proftpd
# cp mod_sql-4.0.8.tar.gz proftpd/contrib/
# cd proftpd/contrib/
# tar -zxvf mod_sql-4.0.8.tar.gz
# ee mod_sql_mysql.c
将#include <mysql/mysql.h>改成#include </usr/local/mysql/include/mysql/mysql.h>
这里假设你的Mysql安装在/usr/local/mysql
# cd ..

配置使Proftpd支持MySQL认证：
#./configure --prefix=/usr/local/proftpd /
--with-modules=mod_sql:mod_sql_mysql /
--with-includes=/usr/local/mysql/include/mysql /
--with-libraries=/usr/local/mysql/lib/mysql
# make
# make install
安装完之后，可以按下列步骤进行测试，Proftpd是否能正常工作：
# sh sample-configurations/PFTEST.install
测试的所需要的临时文件被放置在/tmp/PFTEST目录中，运行命令：
# ./proftpd -n -d 5 -c /tmp/PFTEST/PFTEST.conf
如果能正常运行，你可以发现有很多的信息而且最后一行会出现：
ProFTPD 1.2.6 (built ***) standalone mode STARTUP
说明服务启动了，它用的端口是2021，你可以用用户proftpd与密码 proftpd进行登录测试。如果正常，你可以做下列准备；否则要检查安装是否正确。

为FTP服务建立相应的数据库及其表。
1、你可以为此服务建立专门的数据库，也可以放在其它的数据库中。在此我专门建立一个专门的数据库FTP：

> create database proftpd;

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 proftpd;
> create table ftpusers (
> userid TEXT NOT NULL,
> passwd TEXT NOT NULL,
> uid INT NOT NULL,
> gid INT NOT NULL,
> home 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；home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，例如：用来记录用户登录次数的count，或者是日期的date，如果你对配置熟悉了之后，你可以根据自己的喜欢添加更多的功能。在此就不多讲。
3、如果你想需要所有的功能，你还可以添加另外一个需要的表：ftpgroups，也就是确定组的表格，当然也可以不用，这里讲一个它的格式：
create table ftpgroups (
groupname TEXT NOT NULL,
gid SMALLINT NOT NULL,
members TEXT NOT NULL
);
其中groupname是组的名称，gid是系统组的ID，members是组的成员。注意：多成员，他们之间要用逗号隔开，不能使用空格。

为空表格插入记录：
INSERT INTO ftpusers (userid, passwd, uid, gid, home, shell)
values ('test', 'test', '2000', ‘2000’, '/home/ftp/test', ' ');

按此格式你可以插入这每一个用户添加一个记录。
如果你要想应用到更多的功能，且建立了组的表格，你也要为此添加记录，不过一定要注意在members的字段多个成员一定要用逗号隔开。

为FTP用户建立相应的系统用户。
在本例中，只整个FTP服务只提供一个有效的系统用户ftpusers和组ftpgroups，当然你也可以设置多个系统用户。但出于安全的考虑，我只设一个，用他来启动FTP daemon，并把所有的FTP用户映射到这个用户。

先建立FTPGRP组：
# pw groupadd ftpgroups –g 2000
建立FTPUSR用户：
# pw adduser ftpusers –u 2000 –g 2000 –d /home/ftp –s /nonexistent

为FTPUSR建立HOME，把所有的FTP user 活动空间全放在此目录下：
# mkdir /home/ftp
# chown ftpusers /home/ftp
# chgrp ftpgroups /home/ftp

现在可以在mysql的FTP数据库中建立磁盘限制数据表了,呵呵,利用phpmyadmin帮忙就可以了:

CREATE TABLE quotalimits (
name VARCHAR(30),
quota_type ENUM("user", "group", "class", "all") NOT NULL,
per_session ENUM("false", "true") NOT NULL,
limit_type ENUM("soft", "hard") NOT NULL,
bytes_in_avail FLOAT NOT NULL,
bytes_out_avail FLOAT NOT NULL,
bytes_xfer_avail FLOAT NOT NULL,
files_in_avail INT UNSIGNED NOT NULL,
files_out_avail INT UNSIGNED NOT NULL,
files_xfer_avail INT UNSIGNED NOT NULL
);

CREATE TABLE quotatallies (
name VARCHAR(30) NOT NULL,
quota_type ENUM("user", "group", "class", "all") NOT NULL,
bytes_in_used FLOAT NOT NULL,
bytes_out_used FLOAT NOT NULL,
bytes_xfer_used FLOAT NOT NULL,
files_in_used INT UNSIGNED NOT NULL,
files_out_used INT UNSIGNED NOT NULL,
files_xfer_used INT UNSIGNED NOT NULL
);

说明一下，quotatallies表不需要作修改，它记录了用户当前的磁盘使用情况，由程序自动记录
要注意的是quotalimits 表中一些字段的含意
quota_type 磁盘限额的鉴别,可以设置单各用户，也可以设置一各组中的全部用户，还可以设置全部用户
bytes_in_avail 上传最大字节数，就是FTP用户空间容量 (设置个字段的时候是以byte(字节)为单位，如果要限额在10M，那就是10240000,下面也一样)
bytes_out_avail 下载最大字节数，需要注意的是，这个字段中记录的是用户总共能从服务器上下载多少数据，数据是累计的。
bytes_xfer_avail 总共可传输的文件的最大字节数(上传和下载流量)需要注意的是，这个字段中记录的是用户总共能传输文件的最大字节数，数据是累计的。
files_in_avail INT 总共能上传文件的数目
files_out_avail INT 能从服务器上下载文件的总数目
files_xfer_avail INT 总共可传输文件的数目(上传和下载)

然后再把下面一些SQL语句copy到proftpd.conf中即可,无须改动:

#以下是SQL调用语句，不用修改直接拷贝过去

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


设置proftpd的主配置文件。
Proftpd的配置文件proftpd.conf在/usr/local/etc/目录下，针对不用的认证可以使用不同的配置文件。使用MySQL认证，可以把mod_sql.conf拷贝到/usr/local/etc下面并将其改名为proftpd.conf。
修改proftpd.conf文件，具体内容如下：

#设置FTP服务器的名称：
ServerName “My FTP Server”

#设置FTP服务器的类型：
ServerType standalone
DefaultServer on

#设置根，可以限制用户在某个地方活动，增强服务器的安全性。
DefaultRoot ~

#设置FTP服务端口号，标准的FTP服务端口是21。
Port 21

#设置新建文件或目录时，设置权限的掩码：
Umask 022

#设置系统日志文件：
SystemLog /var/log/ftp.syslog

#设置记录文件传输的日志文件：
TransferLog /var/log/ftp.transferlog

#设置最大的尝试登录的次数，如果超过自动断开连接：
MaxLoginAttempts 3

#设置断点继传
AllowRetrieveRestart on

#针对IP的速率限制（以BPS为单位，下面是80KB/S）
RateReadBPS 80000
RateWriteBPS 80000

#设置MySQL认证：
<Global>
#数据库联接的信息，DatabaseName是数据库名， HostName是主机名，
#Port是端口号，UserName是连接数据库的用户名，Password是密码。
SQLConnectInfo DatabaseName@HostName:Port UserName Password
#我的实例是SQLConnectInfo FTP@localhost:3306 root ******
#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。
SQLUserInfo FTPUSERS userid passwd uid gid home shell
#设置如果shell为空时允许用户登录：
RequireValidShell off
#数据库的鉴别，这里是用于用户的方式：
SQLAuthenticate users
#如果home目录不存在，则系统会为根据它的home项新建一个目录：
SQLHomedirOnDemand on
</Global>

#防止DoS攻击，设置最大的了进程：
MaxInstances 30

#设置正常服务的系统用户与组：
User ftpusers
Group ftpgroups

#设置用户登录时显示的信息及进入各个子目录中的信息：
DisplayLogin welcome.msg
DisplayFirstChdir .message
#设置最大的登录数：
MaxClients10
#支持断点续传：
AllowRetrieveRestart on
AllowStoreRestart on

测试:
完成了文件的配置，你可以启动Proftpd服务了，用来测试是否成功：
修改apahce的配置文件，使通过mysql添加的proftpd用户目录能被web浏览
将UserDir public_html
改为UserDir /home/ftp/*/
然后重启apache使改动生效，再启动proftpd用test帐号登陆,进行测试。
# /usr/local/proftpd/sbin/proftpd –n &

注意：在FreeBSd4.7和5.0下运行Proftpd，这时可能会提示下面的错误
/usr/local/ftp/sbin/proftpd: error while loading shared libraries: libmysqlclient.so.10: cannot open shared object file:
No such file or directory
解决方案如下：
安装mysql时，将mysql库所在的目录添加进配置文件中，例如
echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
然后执行ldconfig -v|grep libmysqlclient ，再试试！

或者将/usr/local/mysql/lib/mysql/下的文件全部copy到/usr/lib中即可。

如果test登陆成功的话，在test用户根目录里放置一个index.html文件
通http://yourserver/~test/看能否访问。

未完待续,希望起到抛砖引玉的作用,大家可以接着写啊,偶技术太烂了,已经好一阵子没玩过BSD了,555~~~~

# We put our mod_sql directives in a <Global> block so they'll be
# inherited by the <Anonymous> block below, and any other <VirtualHost>
# blocks we may want to add. For a simple server these don't need to
# be in a <Global> block but it won't hurt anything.
<Global>

# Specify our connection information. Both mod_sql_mysql and
# mod_sql_postgres use the same format, other backends may specify a
# different format for the first argument to SQLConnectInfo. By not
# specifying a fourth argument, we're defaulting to 'PERSESSION'
# connections -- a connection is made to the database at the start of
# the session and closed at the end. This should be fine for most
# situations.

# SQLConnectInfo dbname@host:port username password
SQLConnectInfo ftp@localhost:3306 root 12345678

# Specify our authentication schemes. Assuming we're using
# mod_sql_mysql, here we're saying 'first try to authenticate using
# mysql's password scheme, then try to authenticate the user's
# password as plaintext'. Note that 'Plaintext' isn't a smart way to
# store passwords unless you've got your database well secured.
SQLAuthTypes Backend Plaintext

# Specify the table and fields for user information. If you've
# created the database as it specifies in 'README.mod_sql', you don't
# need to have this directive at all UNLESS you've elected not to
# create some fields. In this case we're telling mod_sql to look in
# table 'users' for the fields 'username','password','uid', and
# 'gid'. The 'homedir' and 'shell' fields are specified as 'NULL' --
# this will be explained below.

# SQLUserInfo users username password uid gid NULL NULL
SQLUserInfo ftpusers userid passwd uid gid home shell


# Here we tell mod_sql that every user it authenticates should have
# the same home directory. A much more common option would be to
# specify a homedir in the database and leave this directive out. Note
# that this directive is necessary in this case because we specified
# the homedir field as 'NULL', above. mod_sql needs to get homedir
# information from *somewhere*, otherwise it will not allow access.

# SQLDefaultHomedir "/tmp"

# This is not a mod_sql specific directive, but it's here because of
# the way we specified 'SQLUserInfo', above. By setting this to
# 'off', we're telling ProFTPD to allow users to connect even if we
# have no (or bad) shell information for them. Since we specified the
# shell field as 'NULL', above, we need to tell ProFTPD to allow the
# users in even though their shell doesn't exist.

RequireValidShell off

# Here we tell mod_sql how to get out group information. By leaving
# this commented out, we're telling mod_sql to go ahead and use the
# defaults for the tablename and all the field names.
# SQLGroupInfo groups groupname gid members

# For small sites, the following directive will speed up queries at
# the cost of some memory. Larger sites should read the complete
# description of the 'SQLAuthenticate' directive; there are options
# here that control the use of potentially expensive database
# queries. NOTE: these arguments to 'SQLAuthoritative' limit the way
# you can structure your group table. Check the README for more
# information.

SQLAuthenticate users

# Finally, some example logging directives. If you have an integer
# field named 'count' in your users table, these directives will
# automatically update the field each time a user logs in and display
# their current login count to them.
# SQLNamedQuery getcount SELECT "count, userid from users where userid='%u'"
