前言

由于有给服务器传文件的需求,又没有FTP,就想着先给服务器装个FRP内网穿透;就百度了一下,结果好几天也没成功,后来又不甘心,又继续搞,终于有结果了,记录一下。

安装vsftpd

  • 安装 vsftpd
1
2
sudo apt update
sudo apt install vsftpd
  • 配置 vsftpd

vsftpd的配置文件默认位于 /etc/vsftpd.conf下,我们编辑一下

# 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=YES
#
# 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
#
# 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
#
# 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=NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=NO
#
# 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
#
# 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
#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
#
# 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
#
local_root=/home/ftp

# 以下配置需要自己添加,否则不可用,可根据自己需求更改
allow_writeable_chroot=YES
pasv_enable=YES
pasv_min_port=40000
pasv_max_port=40010
tcp_wrappers=YES
listen_port=21
pasv_address=101.133.132.187
  • 添加用户
1

3
sudo useradd -d /home/ftp/uftp -m ftpuser #此处ftpuser为添加的用户名
sudo passwd ftpuser #给该用户设置密码,密码不会回显,且需要输入两次
chomd 777 /home/ftp -R #更改ftp文件夹的权限
  • 重启 vsftpd 服务
1
sudo service vsftpd restart
  • 防火墙设置

开启对应的端口 20 21口等

  • 测试 FTP 连接
1
ftp 127.0.0.1

然后输入上边设置的用户名和密码,应该会提示success,这样就连上了;接着可以试试本地电脑连接服务器ftp,ftp://ip,可以连上就说明成功了。

设置开机自启

由于,我想要其开机自启这样方便点,所以又查了查资料,记录一下。

  • 创建 systemd 服务文件
1
sudo vi /etc/systemd/system/frps.service
  • 添加配置

[Unit]
Description=frps Service
After=network.target

[Service]
ExecStart=/home/www/frp/frps -c /home/www/frp/frps.ini
Restart=always
User=root
Group=root

[Install]
WantedBy=multi-user.target

上面ExecStart=/home/www/frp/frps -c /home/www/frp/frps.ini是我设置的路径,可以替换为你自己的。

其中:

1

4
`/full/path/to/your/frps`: `frps` 是可执行文件的绝对路径。
`/full/path/to/your/frps.ini`: `frps.ini`是 配置文件的绝对路径。
`your_username`: 执行服务的用户名。
`your_group`: 执行服务的用户组。
  • 重新加载 systemd 配置
1
sudo systemctl daemon-reload
  • 设置开机自启
1
2
sudo systemctl enable frps
sudo systemctl start frps
  • 查看是否开启
1
sudo systemctl status frps //frps是上面创建的systemd服务文件的名字

结束开机自启

另外,你如果需要关闭开机自启,可执行以下操作

1
2
3
sudo systemctl stop frps	//停止frps
sudo systemctl disable frps //关闭开机自启
sudo systemctl enable frps //启用开机自启

结语

总觉得还有什么步骤忘记了,先不管,之后再说😂
