ubuntu服务器安装FTP服务
ubuntu服务器安装FTP服务
参考教程
一、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
二、安装配置FTP
ftp服务器相比seafile网盘就简单很多,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,可以的话说明安装成功。
配置环境
打开配置文件vim /etc/vsftpd.conf
将里面的内容覆盖成如下的内容:
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：用户被限制在自己的主目录下。用户名单来源于/etc/vsftpd.chroot_list。
以及
pam_service_name=ftp原配置中为vsftpd，ubuntu用户需要更改成ftp
其他有兴趣的可以去查看其他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
然后进入用户，
su username
cd ~
建立ftp访问的文件pub,并给权限
mkdir pub
chmod 777 -R pub
限制用户username只能通过ftp登陆，而不能直接登陆服务器，可以返回ubuntu账户或者root账户操作
sudo usermod -s /sbin/nologin username
新建/etc/vsftpd.chroot_list，并将username加入进去
之后启动或者重启vsftpd即可
/etc/init.d/vsftpd restart
/etc/init.d/vsftpd start
然后在文件管理器那边输入 ftp:www.你的域名,然后输入用户名和密码。
大功告成！
