CentOS 6.5 配置vsftpd

[日期:2017-03-03] 来源:Linux社区  作者:justinzhang [字体: ]

CentOS 6.5 配置vsftpd

1. 下载vsftpd:

#yum –y install vsftpd

2. 关闭iptables

查看防火墙状态:/etc/init.d/iptables status

关闭:service iptables stop  或者 /etc/init.d/iptables stop

每次开机自动关闭:

chkconfig --level 35 iptables off

3. 关闭SELinux,

查看selinux状态:

[root@localhost ~]# /usr/sbin/sestatus –v

/usr/sbin/setenforce 0 #使SELinux工作模式变成permissive模式
/usr/sbin/setenforce 1 #使SELinux工作模式变成enforcing模式

这样就可以实时控制SELinux的启用和不启用了。

三个参数介绍介绍

  • enforcing — The SELinux security policy is enforced.
  • permissive — The SELinux system prints warnings but does not enforce policy.
  • disabled — SELinux is fully disabled. SELinux hooks are disengaged from the kernel and the pseudo-file system is unregistered.

永久关闭SELinux

编辑/etc/selinux/config,找到SELINUX 行修改成为:SELINUX=disabled:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled

# SELINUXTYPE= can take one of these two values:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted 

重启系统。 

4. 配置vsftpd.conf文件

# 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
=YES
#
# Uncomment this to allow local users to log
in.
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=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.
#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
#
# The target log
file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
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
#
# The name of log
file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING
- changing this filename affects /etc/logrotate.d/vsftpd.log
#xferlog_file
=/var/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file
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
=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().
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. To listen on IPv4 and IPv6
# sockets, 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

5。 编辑user_list文件,允许cent用户访问FTP

[root@localhost ~]# vi /etc/vsftpd/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.
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody
cent

6. 共享目录权限配置,启动服务

[root@localhost ~]# mkdir /var/public_root
[root@localhost
~]# chown -R cent /var/public_root
[root@localhost
~]# chmod -R 755 /var/public_root [root@localhost~]# service vsftpd start
Starting vsftpd
for vsftpd:                                [  OK  ]


[root@localhost var]# chkconfig vsftpd on
