首先使用命令查看,系统内是否安装了vsftp

[root@instance_290388 down]# rpm -qa |grep vsftp

如果没有安装,使用命令,进行安装

[root@instance_290388 down]# yum -y install vsftpd

安装完成后,命令进入文件夹

[root@instance_290388 down]# cd /etc/vsftpd/

修改vsftp配置文件

[root@instance_290388 vsftpd]# vi vsftpd.conf

将vsftp.conf内容,替换成如下的内容

# Example config file /etc/vsftpd/vsftpd.conf
#
# 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. for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf. manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
#anonymous_enable=YES
#
# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is . You may wish to change this to ,
# if your users expect that ( is used by most other ftpd's)
local_umask=
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/xferlog
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
idle_session_timeout=
#
# You may change the default value for timing out a data connection.
data_connection_timeout=
#
# 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
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to blah FTP service Hello KanYun.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES #pasv_enable=NO allow_writeable_chroot=YES pam_service_name=vsftpd
userlist_enable=NO
tcp_wrappers=YES userlist_file=/etc/vsftpd/user_list userlist_enable=YES
userlist_deny=YES
#此设置表示ftp用户登录之后进入哪个目录,跟用户主目录一致
local_root=/data/kanyun
tcp_wrappers=YES
use_localtime=YES

添加Ftp用户

#颜色标注为新增的用户名
[root@instance_290388 vsftpd]# useradd -d /data/kanyun kanyun  #增加用户kanyun,并制定test用户的主目录为/data/kanyun 与上面颜色标注的路径一致

设置用户密码

[root@instance_290388 vsftpd]# passwd kanyun

启动vsftp

#注意关闭防火墙
[root@instance_290388 vsftpd]# service vsftpd start

启动ftp之后,建议使用命令行登录ftp,不建议直接使用xftp登录ftp,因为使用xftp登录ftp,报错的话看不到报错信息,使用命令行登录ftp,方法如下:

可以看到,使用命令行,可以很清楚自己配置的错误,然后就可以一一解决了!

删除用户使用命令

#在root用户下
[root@instance_290388 vsftpd]# userdel -r kanyun
#在普通用户下
[root@instance_290388 vsftpd]# sudo userdel -r kanyun

卸载vsftp命令

[root@instance_290388 vsftpd]# rpm -e vsftpd

这两天又在Ubuntu上安装vsftp,Ubuntu的vsftp的配置文件都在/etc目录下,当然重点不是这个:

重点是这样的,我新增了一个用户,并设置密码,登陆Ftp老是报错

530 Login incorrect.

但是我的配置没有问题啊,老用户也是可以登陆的,于是我把vsftp卸载了,再新增用户,再装vsftp,结果还不行,在网上各种找答案,网上说改vsftp.conf的都不行,删用户,再新增用户,弄了差不多一个星期,后来想了想,因为之前新增用户图方便把用户密码设置成跟用户名一样了,所以想改一下,把密码改成了别的,结果一实验就等成功了。但是之前给用户设置密码,它也没有提示不让设置成跟用户名一样啊,结果我又把密码改成了跟用户名一样,又登不上去了 还是530 Login incorrect. 晕!

所以记录一下,看来在linux里设置密码真的小心了:用户名不要跟密码设置成一样
