ubuntu服务器安装FTP服务

参考教程

[ubuntu16.04搭建ftp服务器

1、实验环境

• 腾讯云学生机64位ubuntu16.04
• 腾讯云已备案解析域名
• 使用腾讯云webshell登入服务器

2、安装配置FTP

ftp服务器相比seafile网盘就简单不少,主要问题出在配置上

下载ftp

sudo apt-get update 
sudo apt-get install vsftpd

安装完成,输入vsftpd -version查看版本,能够的话说明安装成功。

配置环境

打开配置文件vim /etc/vsftpd.conf

将里面的内容覆盖成以下的内容:

listen=NO
listen_ipv6=YES

# Allow anonymous FTP? (Disabled by default).
anonymous_enable=NO

# 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

# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# If enabled, vsftpd will display directory listings with the time
# in  your  local  time  zone.  The default is to display GMT. The
# times returned by the MDTM FTP command are also affected by this
# option.
use_localtime=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

# 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.
# Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES


# You may fully customise the login banner string:
ftpd_banner=Welcome to FTP service.


# 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

# This option should be the name of a directory which is empty.  Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
secure_chroot_dir=/var/run/vsftpd/empty
#
# This string is the name of the PAM service vsftpd will use.
# pam_service_name=vsftpd
pam_service_name=ftp

# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
ssl_enable=NO

#
# Uncomment this to indicate that vsftpd use a utf8 filesystem.
utf8_filesystem=YES

里面有几个重要的参数

chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list 
上面的这几个配置实现的功能是：用户被限制在本身的主目录下。用户名单来源于/etc/vsftpd.chroot_list。

以及

pam_service_name=ftp原配置中为vsftpd，ubuntu用户须要更改为ftp

其余有兴趣的能够去查看其余人的相关教程有介绍

新建用户

sudo useradd -m -s /bin/bash username -g ftp
sudo passwd seafile

而后进入用户，

su username
cd ~

创建ftp访问的文件pub,并给权限

mkdir pub
chmod 777 -R pub

限制用户username只能经过ftp登录，而不能直接登录服务器，能够返回ubuntu帐户或者root帐户操做

sudo  usermod -s /sbin/nologin username

新建/etc/vsftpd.chroot_list，并将username加入进去

以后启动或者重启vsftpd便可

/etc/init.d/vsftpd restart
 /etc/init.d/vsftpd start

而后在文件管理器那边输入 ftp:www.你的域名,而后输入用户名和密码。

大功告成！
