安装mysql(不要使用红帽的RPM版的mysql)

使用编译或静态库安装mysql

1、编译安装pam_mysql
下载软件：
http://downloads.sourceforge.net/project/pam-mysql/pam-mysql/0.7RC1/pam_mysql-0.7RC1.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fpam-mysql%2F&ts=1308550644&use_mirror=nchc

tar xzvf pam_mysql-0.7RC1.tar.gz -C /usr/local/src/
cd /usr/local/src/pam_mysql-0.7RC1/
./configure --with-mysql=/opt/mysql/ && make && make install

rpm包安装

rpm -ivh pam_mysql-0.7RC1-1.x86_64.rpm
Preparing...                ########################################### [100%]
   1:pam_mysql              ########################################### [100%]

2、安装vsftpd

yum -y install vsftpd

配置vsftpd服务器

vim /etc/vsftpd/vsftpd.conf

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
anon_upload_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
chroot_local_user=YES
listen=YES
guest_enable=YES
guest_username=virtual
pam_service_name=/etc/pam.d/vsftpd.mysql
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

vim /etc/pam.d/vsftpd.mysql

auth required  /usr/lib/security/pam_mysql.so user=ftp passwd=123456 host=localhost db=vsftpd table=users usercolumn=username passwdcolumn=password crypt=2
account required  /usr/lib/security/pam_mysql.so user=ftp passwd=123456 host=localhost db=vsftpd table=users usercolumn=username passwdcolumn=password crypt=2

添加一个系统账号，并指定家目录。

useradd virtual -d /ftproot -s /sbin/nologin
chmod 755 /ftproot/

3、配置mysql

mysql>detele  from  mysql.user  where  user='  ';

mysql>detele  from  mysql.db  where  user='  ';

mysql> create database vsftp;

mysql>create table vsftp.users(id int auto_increment primary key, username char(30), password char(50));

mysql>insert  into  vsftp.users(username,password)  values('a',password('123')),('b',password('456')),('c',password('789'));

mysql>grant all on vsftp.* to runftp@'10.170.36.27' identified by '123;
 
mysql>flush  privileges;

service vsftpd restart

让虚拟用户登录服务器时记录登录状态和时间：

mysql> create table logs(
    -> msg varchar(255),
    -> user char(16) ,
    -> pid int(11),
    -> host char(32),
    -> rhost char(32),
    -> logtime timestamp);
Query OK, 0 rows affected (0.01 sec)

vim /etc/pam.d/vsftpd.mysql
auth required  /usr/lib/security/pam_mysql.so user=ftp passwd=123456 host=localhost db=vsftpd table=users usercolumn=username passwdcolumn=password crypt=2 sqllog=1 logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhost logtimecolumn=logtime verbose=1
account required  /usr/lib/security/pam_mysql.so user=ftp passwd=123456 host=localhost db=vsftpd table=users usercolumn=username passwdcolumn=password crypt=2 sqllog=1 logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhost logtimecolumn=logtime verbose=1

service vsftpd restart

虚拟用户扩展

vim /etc/vsftpd/vsftpd.conf
user_config_dir=/etc/vsftpd/ew  定义用户的在扩展的目录中

给a用户定义一个配置文件

vim /etc/vsftpd/ew/a
local_root=/home/ftpsite/a
anon_max_rate=200000(200kb)

给b用户定义一个配置文件

vim /etc/vsftpd/ew/b
local_root=/home/ftpsite/b
anon_max_rate=100000(100kb)
anon_world_readable_only=NO
anon_upload_enable=YES
write_enable=YES

给c用户定义一个配置文件

vim /etc/vsftpd/ew/c
local_root=/home/ftpsite/c
anon_world_readable_only=NO
anon_max_rate=0
anon_upload_enable=YES
write_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
