操作系统：虚拟机5.5.1下Redhat linux AS4
软件：vsftpd-2.0.4，mysql-4.1.20，pam_mysql-0.5
具体操作如下：
1、安装mysql-4.1.20数据库：
1.1创建mysql组和mysql用户
＃groupadd mysql
＃useradd -g mysql mysql
修改/root下的.bash_profile的这一行：
＃vi /root/.bash_profile
PATH=$PATH: $HOME/bin
为
PATH=$PATH: $HOME/bin:/usr/local/mysql/bin
1.2安装mysql
＃tar -zxvf mysql-4.1.20.tar.gz
＃cd mysql-4.120
＃./configure --prefix=/usr/local/mysql (--with-charset=gbk --with-charset=gb2312 --with-charset=utf8 --with-extra-charsets=complex --without-uca)
——括号内为我在apache-2.0＋mysql-4.1.20＋php-4.4.2＋phpMyAdmin-2.6.2＋Zend-3.0.0时添加字符时用的，在此省略了！
＃make
＃make install
＃cd 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
向/etc/ld.so.conf中加入两行：
＃vi /etc/ld.so.conf
/usr/local/mysql/lib/mysql
/usr/local/lib
载入库，执行ldconfig -v
＃ldconfig -v
1.3测试mysql是否工作
＃/usr/local/mysql/bin/mysqld_safe &
＃ps -ef |grep mysql
查看mysql_safe是否工作在进程里
1.4设置mysql为自启动将mysql-4.1.20安装目录下的support-files目录中的mysql.server文件拷到/etc/init.d目录下
＃cp /mysql-4.1.20/support-files/mysql.server /etc/init.d/mysql
＃chmod 755 /etc/init.d/mysql
创建硬链接
＃cd /etc/rc3.d（文本方式启动）
＃ln -s /etc/init.d/mysql S85mysql
＃ln -s /etc/init.d/mysql K85mysql
设置mysql密码(远程登陆加–h IP地址)
＃/usr/local/mysql/bin/mysqladmin –uroot password'123456'
进入mysql数据库(远程登陆加–h IP地址)
＃/usr/local/mysql/bin/mysql –uroot –p123456
配置mysql数据库：
mysql>create database ftpd;
mysql>use ftpd;
mysql>create table user(name char(20) binary,passwd char(20) binary);
mysql>insert into user (name,passwd) values ('test1','123');
mysql>insert into user (name,passwd) values ('test2','321');
mysql>grant select on ftpd.user to ftpd@localhost identified by '12345';
mysql>flush privileges; 刷新权限设置
mysql>quit;
2、下载libpam-mysql-5.0进行安装编译
下载地址如下：
http://nchc.dl.sourceforge.net/s ... am_mysql-0.5.tar.gz
2.1假设我们把它放在了/soft目录下
＃cd /soft
＃tar zxvf pam_mysql-0.5.tar.gz
＃cd pam_mysql-5.0
＃make
＃cp pam_mysql.so /lib/security
我的问题就在于此处，make编译不出来pam_mysql.so文件，提示一个错误！内容如下：
mkdir -p ./dynamic

make: *** [dynamic/pam_mysql.o] Error 1
2.2建立PAM认证信息
＃vi /etc/pam.d/ftp 添加的内容如下：
auth required /lib/security/pam_mysql.so user=ftpd passwd=123456 host=localhost db=ftpd table=user usercolumn=name passwdcolumn=passwd crypt=0
account required /lib/security/pam_mysql.so user=ftpd passwd=123456 host=localhost db=ftpd table=user usercolumn=name passwdcolumn=passwd crypt=0
注意：
crypt=n
crypt=0: 明文密码
crypt=1: 使用crpyt()函数(对应SQL数据里的encrypt()，encrypt()随机产生salt)
crypt=2: 使用MYSQL中的password()函数加密
crypt=3：表示使用md5的散列方式
2.3建立本地虚拟用户
# useradd -d /home/ftpd -s /sbin/nologin ftpd
3、安装配置vsftpd的过程：
3.1安装vsftpd过程
＃cd /soft/vsftpd-2.0.3 //进入vsftpd-2.0.3的源代码目录
＃make clean //清除编译环境
＃vi builddefs.h //继续编辑builddefs.h 文件，文件内容如下：
#ifndef VSF_BUILDDEFS_H
#define VSF_BUILDDEFS_H
#define VSF_BUILD_TCPWRAPPERS
#undef VSF_BUILD_PAM
#define VSF_BUILD_SSL
#endif /* VSF_BUILDDEFS_H */
将以上define VSF_BUILD_PAM行的undef改为define，支持tcp_wrappers，支持PAM认证方式，支持SSL，和匿名用户形式是一样的。
＃make //直接在vsftpd-2.0.3里用make编译
＃ls -l vsftpd
-rwxr-xr-x 1 root root 86088 Jun 6 22:26 vsftpd //可执行程序已被编译成功
创建必要的帐号，目录：
＃useradd nobody //可能你的系统已经存在此帐号，那就不用建立
＃mkdir /usr/share/empty //可能你的系统已经存在此目录，那就不用建立
＃mkdir /var/ftp //可能你的系统已经存在此目录，那就不用建立
＃useradd -d /var/ftp ftp //可能你的系统已经存在此帐号，那就不用建立
＃chown root:root /var/ftp
＃chmod og-w /var/ftp
如果你不想让用户在本地登陆，那么你需要把他的登陆SHELL设置成/sbin/nologin，比如以上的nobody和ftp我就设置成/sbin/nologin
安装vsftp配置文件，可执行程序，man等:
＃install -m 755 vsftpd /usr/local/sbin/vsftpd
＃install -m 644 vsftpd.8 /usr/share/man/man8
＃install -m 644 vsftpd.conf.5 /usr/share/man/man5
＃install -m 644 vsftpd.conf /etc/vsftpd.conf
3.2安装完成了，那么我们开始进行简单的配置
＃vi /etc/vsftpd.conf
