Red Hat/CentOS Linux 配置 FTP服务器

Red Hat Enterprise Linux 配置FTP 服务器使用的是vsftpd服务,通过界面形式安装哦。


安装:在安装linux时,选择FTP服务
图1:在linux窗口应用程序-系统设置-服务设置-服务

图2:勾选vsftpd协议,选保存后,重启linux


此处可以打上vsftpd(ftp上传),httpd(web协议),mysqld(mysql数据库)三个选项都钩选了。
useradd -d ./alidata/www/default  –g www -s /sbin/nologin mdrss001


第二步:打开终端

[root@localhost ~]# gedit /etc/vsftpd/vsftpd.conf 

 /*修改vsftpd文件配置文件如下*/
anonymous_enable=YES 改成 NO
加入连接端口
listen_port=21 指定端口,也可以不配置21端口,默认的就是21端口//更多配置请看下面的vsftpd.conf 配置说明文件

[root@localhost ~]# useradd -d /var/www/html –g ftp -s /sbin/nologin skyfen      Centos 操作此时会报一个错,不过没关系

[root@localhost ~]# passwd skyfen /*为skyfen用户设置密码*/
Changing password for user unichn.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
第三步:权限
[root@localhost www]# chown skyfen.1234567 html –R /*赋予文件夹执行权限*/
[root@localhost www]# chmod 777 html

第四步:[root@localhost html]# service vsftpd restart  //重启服务器


第五步:在FTP软件中配置用户

如果文件无法上传或目录无法显示则要如下操作
1、# sestatus -b | grep ftp #查看 ftpd_disable_trans状态

只要将ftpd_disable_trans   off
修改为ftpd_disable_trans  on后,

2、#setsebool -P ftpd_disable_trans on

修改后重启vsftp
3、#/etc/init.d/vsftpd restart


vsftpd.conf 配置说明文件
vsftpd.conf文件翻译解释

[root@linux01 Server]# cat /etc/vsftpd/vsftpd.conf
# 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 # 允许匿名登录
#
# Uncomment this to allow local users to log in.
local_enable=YES # 允许本地帐户登录
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES # 开放对本地用户的写权限
#
# 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 # 本地用户的文件生成掩码
#
# 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 # 显示目录下的.message
#
# Activate logging of uploads/downloads.
xferlog_enable=YES # 启用上传和下载日志
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES # 启用FTP数据端口
#
# 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/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format
xferlog_std_format=YES # 使用标准的ftpd xferlog日志格式
#
# 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_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 # FTP服务器处于独立启动模式(相对于受xinnetd管理的启动模式)
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd whith two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
pam_service_name=vsftpd # PAM认证服务的配置文件名称,/etc/pam.d/vsftpd
userlist_enable=YES # FTP将检查userlist_file(/etc/vsftpd/user_list)中用户是否可以访问FTP服务器
tcp_wrappers=YES # 使用tcp_wrappers作为主机访问控制方式,/etc/host.allow和/etc/hosts.deny。
