vsftpdԴ???ȡ
方法一：登录出现 vsftpd login incorrect 报错。
解决方法：
cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp
path为vsftp解压缩源文件目录
这是源码因为我们RHEL启用了PAM,所在用到vsftp时需要用到 /etc/pam.d/ftp这个文件（默认源码安装的不会有这个文件），因此除了匿名用户外本地用户无法登录。源码
方法二：
在测试Checkpoint的源码php源码短网站***1 R6x的时候，遇到了这个错误。源码这说明client端跟server端的源码直连网盘源码连接性是没问题。但是源码就是想不出为什么，还以为是源码用户名和口令错误呢。后来才google了一下，源码发现是源码server端的配置有问题。
检查/etc/vsftpd/user_list和/etc/ftpusers，源码是源码这个文件/etc/vsftpd/vsftpd.conf少了一行：
复制代码
代码如下:
pam_service_name=vsftpd
$ echo ‘pam_service_name=vsftpd’ /etc/vsftpd/vsftpd.conf
$ service vsftpd restart
error就消除了！
下面是源码溯源码查询制度更详细的方法：

# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.

# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore

# mangling on files when in ASCII mode.
# Beware that turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be

#ascii_upload_enable=YES
#ascii_download_enable=YES

# You may fully customise the login banner string:

#chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by

CentOS 6.4中出现Vsftpd中文乱码解决过程
Windows客户端访问FTP应用服务器出现乱码。这是源码由于UTF-8与GBK不兼容而头疼的引起的，采用源码方式编译安装就可将此问题解决。源码乱码解决过程：
1、小程序源码领取首先使用 rpm -e vsftpd卸载系统安装的默认VSFTPD应用服务器：
[root@localhost ~]# rpm -e vsftpd
2、从d
、进入源码包下的ios子弹追踪源码 SPECS目录，并使用rpmbuild -bb vsftpd.spec命令生成vsftpd-2.2.2-.el6.1.x_.rpm：
[root@localhost SPECS]# rpmbuild -bb vsftpd.spec
此时因为系统缺少依赖包会报如下错误：
error: Failed build dependencies:
libcap-devel is needed by vsftpd-2.2.2-.el6.1.x_
tcp_wrappers-devel is needed by vsftpd-2.2.2-.el6.1.x_
我们可以从CentOS6.4安装盘中找到如下RPM软件包进行手动安装，包名如下：
libattr-2.4.-7.el6.i.rpm libcap-devel-2.-5.5.el6.x_.rpm
libattr-2.4.-7.el6.x_.rpm tcp_wrappers-devel-7.6-.el6.i.rpm
libattr-devel-2.4.-7.el6.i.rpm tcp_wrappers-devel-7.6-.el6.x_.rpm
libattr-devel-2.4.-7.el6.x_.rpm tcp_wrappers-libs-7.6-.el6.i.rpm
libcap-2.-5.5.el6.i.rpm tcp_wrappers-libs-7.6-.el6.x_.rpm
libcap-2.-5.5.el6.x_.rpm vsftpd-2.2.2-.el6_3.1.src.rpm
libcap-devel-2.-5.5.el6.i.rpm
、将以上各包使用rpm -ivh *.rpm -force --nodeps命令进行强制安装：
[root@localhost rpm]# rpm -ivh *.rpm --force --nodeps
warning: libattr-2.4.-7.el6.i.rpm: Header V3 RSA/SHA1 Signature, key ID cb9de: NOKEY

、再次使用rpmbuild -bb vsftpd.spec对vsftpd-2.2.2-.el6.1.x_.rpm包重新进行编译：
[root@localhost SPECS]# rpmbuild -bb vsftpd.spec
、进入x_目录，此时可以看到该目录下已经生成相关RPM包：
命令模式如下：
复制代码
代码如下:
[root@localhost RPMS]# cd x_/
[root@localhost x_]# ls
vsftpd-2.2.2-.el6.1.x_.rpm vsftpd-debuginfo-2.2.2-.el6.1.x_.rpm
、重新安装进行过源码修改的vsftpd应用服务器组件包：
[root@localhost x_]# rpm -ivh vsftpd-2.2.2-.el6.1.x_.rpm
Preparing... ########################################### [%]
1:vsftpd ########################################### [%]
、CentOS6.4修改系统默认字符集：
[root@localhost /]# vi /etc/sysconfig/in
将原文件修改为如下内容：
复制代码
代码如下:
#LANG="zh_CN.UTF-8"
LANG="zh_CN.GB"
SUPPORTED="zh_CN.GB:zh_CN:zh:zh_CN.GB:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun"
此时所有修改工作已经完成，重起FTP应用服务器之后我们在windows系统中使用IE浏览器以及前期应用软件进行测试中文乱码问题消失。该解决办法同样适用于RHEL6系列操作系统中存在的VSFTPD于windows客户端字符集兼容原因导致的乱码问题。
