一、卸载

1、查看当前服务器中的vsftpd

rpm -qa|grep vsftpd

例如结果为：vsftpd-2.2.2-13.el6_6.1.x86_64

2、执行卸载

rpm -e vsftpd-2.2.2-13.el6_6.1.x86_64

返回：卸载时自动备份vsftp的用户列表文件

warning: /etc/vsftpd/vsftpd.conf saved as /etc/vsftpd/vsftpd.conf.rpmsavewarning: /etc/vsftpd/user_list saved as /etc/vsftpd/user_list.rpmsave

3、删除遗留的文件

rm -rf /etc/vsftpd

二、安装

yum -y install vsftpd

三、配置

1、修改配置文件，/etc/vsftpd/vsftpd.conf，可以整个覆盖

# 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.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.## Allow anonymous FTP? (Beware - allowed by default if you comment this out).anonymous_enable=NO## Uncomment this to allow local users to log in.# When SELinux is enforcing check for SE bool ftp_home_dirlocal_enable=YES## Uncomment this to enable any form of FTP write command.write_enable=YES#allow_writeable_chroot=YES## Default umask for local users is 077. You may wish to change this to 022,# if your users expect that (022 is used by most other ftpd's)local_umask=022## 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 20 (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=600## You may change the default value for timing out a data connection.data_connection_timeout=120## 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=YESascii_download_enable=YES## You may fully customise the login banner string:ftpd_banner=Welcome to blah FTP service.## 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=YESpam_service_name=vsftpduserlist_enable=YESuserlist_deny=NO#这个是ftp根目录，根据你自己的情况配置local_root=/var/ftptcp_wrappers=YESuse_localtime=YES

2、增加FTP账户

useradd ftpadmin -s /sbin/nologin

给ftpadmin设置密码

passwd ftpadmin

输入两遍密码即可

2.1、如果出现 useradd: user 'ftpadmin' already exists，说明用户已经存在，需要先删除，否则还可能登陆不了。

删除用户

userdel ftpadmin

查找遗留的文件和目录

find / -name ftpadmin

例如出来结果：

/var/spool/mail/ftpadmin/home/ftpadmin

哪个要删，哪个不要删，看清楚目录再删除，谨慎使用删除命令，否则遗憾多久就不知道了

rm -rf  /var/spool/mail/ftpadminrm -rf  /home/ftpadmin

3、修改/etc/vsftpd/user_list文件，最后一行添加刚才创建的用户名ftpadmin，也可以整个覆盖

# vsftpd userlist# If userlist_deny=NO, only allow users in this file# If userlist_deny=YES (default), never allow users in this file, and# do not even prompt for a password.# Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers# for users that are denied.rootbindaemonadmlpsyncshutdownhaltmailnewsuucpoperatorgamesnobody#这个就是刚才创建的那个，根据你自己的情况来ftpadmin

4、创建FTP根目录

mkdir /var/ftp

如果上述目录已经存在，只需要修改权限即可

chown -R ftpadmin /var/ftpchmod -R 755 /var/ftp

5、设置开机启动

chkconfig --level 35 vsftpd on

到此，安装配置完毕，重新启动vsftpd服务

service vsftpd restart

就可以使用FlashFXPE或者FileZilla登陆FTP了。

下面以FileZilla为例，看图片
