# 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_dir
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=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=066
#
# 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
# 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.
#
# 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
pam_service_name=vsftpd
userlist_enable=YES
userlist_deny=NO
local_root=/var/public_root
tcp_wrappers=YES
use_localtime=YES
allow_writeable_chroot=YES
- 增加ftp用戶
[root@localhost ~]# useradd cent -s /sbin/nologin
[root@localhost ~]# passwd cent
- 編輯user_list以躯，允許cent用戶訪問(wèn)ftp
[root@localhost vsftpd]# vim user_list
# 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.

- 建立我們的根目錄，并設(shè)置訪問(wèn)權(quán)限
[root@localhost ~]# mkdir /var/public_root
[root@localhost ~]# chown -R cent /var/public_root
[root@localhost ~]# chmod -R 755 /var/public_root
- 啟動(dòng)服務(wù)
[root@localhost ~]# service vsftpd start
或者 systemctl status vsftpd.service
- 設(shè)置開(kāi)機(jī)起動(dòng)
[root@localhost var]# chkconfig vsftpd on
或者 systemctl enable vsftpd.service
- 卸載vsftpd方法
如果服務(wù)器上安裝了vsftpd，配置出錯(cuò)需要卸載vsftpd
[root@localhost ~]# rpm -aq vsftpd
vsftpd-2.0.5-16.el5_5.1 #此處是查找vsftpd的返回結(jié)果
[root@localhost ~]# rpm -e vsftpd-2.0.5-16.el5_5.1
#用rpm -e 查找結(jié)果 進(jìn)行刪除就ok了。warning:
/etc/vsftpd/user_list saved as /etc/vsftpd/user_list.rpmsavewarning:
/etc/vsftpd/ftpusers saved as /etc/vsftpd/ftpusers.rpmsave #刪除時(shí)將備份vsftp的用戶列表文件。
看下是否卸載了vsftpd造垛，進(jìn)行stop及start操作：
[root@localhost ~]# /sbin/serv*ice vsftpd stop
vsftpd: unrecognized service #找不到vsftpd
[root@localhost ~]# /sbin/service vsftpd start
vsftpd: unrecognized service #找不到vsftpd記住，在卸載vsftpd之前晰搀，先停止vsftpd五辽。
- 如果連不上可能是防火墻或者selinux的問(wèn)題，把這兩個(gè)關(guān)了試試外恕。
