CentOS 6.5 配置vsftpd
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 compiledin settings are fairly paranoid. This sample file
# loosens things up a bit, tomake the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This examplefile 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).

#
# Uncomment this to allow local users to login.

#
# Uncomment this to enable any form of FTPwrite command.
write_enable=YES
#
# Default umaskfor 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 effectif 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 thisif you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#

# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode butin fact ignore
# the request. Turn on the below options to have the server actuallydo ASCII
# mangling on files whenin 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

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

# When"listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be usedin conjunction
# with the listen_ipv6 directive.

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
# 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
news
uucp

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