新建了ftp用户， abc, home 目录是 /var/www/abc, 权限是755
如果在 /etc/vsftpd/chroot_list 中添加 abc, 则登录超时，如果去掉，则顺利登录，但是目录是 / 而且可以跳转到其他目录。
现在需求是，如何使 abc 能登录且指定目录为 /var/www/abc， 且不能跳转到其他目录？
lz弄错了个概念，我开始搭建的时候也碰到同样的问题:chroot_list文件里放的用户名是linux系统的用户，一般就是/etc/passwd内可以看到的那些。因为古老的unix还没internet时候是一个主机好多个终端，所以保留了chroot_list里配置同一机器多个用户的功能，现在一般没人这样用了（所以如果看的是鸟哥的linux私房菜的vsftp教程里面就先说的这个方式，就乱了。）。
而ftp的用户应该是在 /etc/vsftpd/vuser_passwd.txt 里配置账户密码，在 /etc/vsftpd/vuser_conf/ftpuser1 这样的配置文件内指定设置。
以下贴上我参考的教程，http://itgeeker.net/centos6-5-64bit-how-to-install-vsftpd/。
vsftp架设(http://itgeeker.net/centos6-5-64bit-how-to-install-vsftpd/)
一、 vsftpd安装
一般在CentOS上都自动安装了vsftd，若没有安装则可以使用以下步骤进行安装
yum -y install vsftpd
service vsftpd start
chkconfig vsftpd on
touch /var/log/vsftpd.log # 创建vsftp的日志文件
在CentOS中，这样就可以完成了一个简单的匿名FTP的搭建。你可以通过文件资源管理器访问 ftp://YOURIPADDRESS 来进行访问，这个时候你可以看到里面有一个目录“pub”，其它什么都不能干。
二、 vsftpd虚拟用户配置
1.编辑配置文件vi /etc/vsftpd/vsftpd.conf
anonymous_enable=NO #设定不允许匿名访问
local_enable=YES #设定本地用户可以访问
chroot_list_enable=YES #使用户不能离开主目录
xferlog_file=/var/log/vsftpd.log #设定vsftpd的服务日志
ascii_upload_enable=YES
ascii_download_enable=YES #设定支持ASCII
pam_service_name=vsftpd #PAM认证文件名,PAM将根据/etc/pam.d/vsftpd进行认证
以下这些是关于Vsftpd虚拟用户支持的重要CentOS FTP服务配置项目。
默认vsftpd.conf中不包含这些设定项目，需要自己手动添加CentOS FTP服务配置。
guest_enable=YES #设定启用虚拟用户功能。
guest_username=ftp #指定虚拟用户的宿主用户。-CentOS中已经有内置的ftp用户了
user_config_dir=/etc/vsftpd/vuser_conf #设定虚拟用户个人vsftp的配置文件存放路径。存放虚拟用户个性化的配置文件名，和虚拟用户名相同
2. 创建chroot list，将用户ftp加入其中
touch /etc/vsftpd/chroot_list
echo ftp >> /etc/vsftpd/chroot_list
3. 进行虚拟用户认证配置
安装Berkeley DB工具，后面找不到db_load的问题就是没有安装这个软件包的原因。
yum install db4 db4-utils
然后，创建用户密码文本vuser_passwd.txt。注意奇数行是用户名，偶行是密码
vi /etc/vsftpd/vuser_passwd.txt
ftpuser1
ftppass1
ftpuser2
ftppass2
生成虚拟用户认证的db文件
db_load -T -t hash -f /etc/vsftpd/vuser_passwd.txt /etc/vsftpd/vuser_passwd.db
编辑认证文件/etc/pam.d/vsftpd，全部注释掉原来语句，并增加以下两行
vi /etc/pam.d/vsftpd
auth required pam_userdb.so db=/etc/vsftpd/vuser_passwd
account required pam_userdb.so db=/etc/vsftpd/vuser_passwd
现在可以创建虚拟用户个性化FTP服务配置文件
mkdir /etc/vsftpd/vuser_conf/
vi /etc/vsftpd/vuser_conf/ftpuser1
local_root=/opt/var/ftp1 #虚拟用户的根目录(根据实际修改)
write_enable=YES 可写
anon_umask=022 #掩码
anon_world_readable_only=NO
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
4.建立目录和设定权限
mkdir /opt/var/ftp/ftpuser1 #给刚建立的用户创建目录
chmod 777 /opt/var/ftp/ftpuser1 #设定目录权限
5. 启动vsftp服务
service vsftpd restart
CentOS上的FTP服务假设完毕！！！
