ubuntu 18.04 搭建ftp服务器
一、安装
sudo apt install vsftpd
查看版本
vsftpd -v二、添加ftp用户
sudo useradd -m kaikai_ftp修改ftp账户密码
sudo pwconv
sudo passwd kaikai_ftp
在/home/kaikai_ftp/目录中创建一个ftpdir目录用于作为ftp的根目录
三、修改服务配置文件
在配置文件/etc/vsftpd.conf 中添加
local_root=/home/kaikai_ftp/ftpdir
allow_writeable_chroot=YES整体配置文件结构及部分解释
# Example config file /etc/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.
#
#
# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=NO # 服务器监听
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
listen_ipv6=YES
#
# Allow anonymous FTP? (Disabled by default).
#anonymous_enable=NO # 匿名访问允许，默认不要开启，
#
# Uncomment this to allow local users to log in.
local_enable=YES # 是否允许本地用户访问
local_root=/home/kaikai_ftp/ftpdir # 自定义上传根目录
allow_writeable_chroot=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES # 允许用户修改文件权限
#
# 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 # FTP上本地的文件权限，默认是077 022?
#
# 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 # 匿名上传允许，默认是NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES # 匿名创建文件夹允许
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES # 用户第一次进入目录的提示信息
#
# 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 # 使用本地时间
#
# Activate logging of uploads/downloads.
xferlog_enable=YES # 一个存有详细的上传下载信息的日志
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES # 在服务器上针对 PORT 类型的连接使用端口 20
#
# 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.
# Note that the default log file location is /var/log/xferlog in this case.
#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 restrict local users to their home directories. See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
chroot_local_user=YES
#
# 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 # 用于指定用户列表文件中的用户是否允许切换到上级目录。默认值为NO。
#chroot_list_enable=YES # 设置是否启用chroot_list_file配置项指定的用户列表文件。默认值为NO。
# (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
#
# Customization
#
# Some of vsftpd's settings don't fit the filesystem layout by
# default.
#
# 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
#
# 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
四、最后重启添加开机启动
重启
sudo service vsftpd start
开机启动
sudo systemctl enable vsftpd五、远程访问
ftp://192.168.123.192 输入添加的用户名和密码进行访问
六、最后可以scp上传文件到ftp用户中
增加用户权限chmod 777 kaikai_ftp
ubuntu 上传下载文件操作
虚拟机连接： ftp 192.168.210.62
ls查看ftp服务器内容
！ls查看本机内容
cd ftpdir转换ftp目录
put xx上传文件到ftpdir文件上步如果没有cd ftpdir就不用到ftpdir目录下查看直接上传到总目录
get xxx下载文件
delete xxx为删除文件
