您可以使用vsftpd來(lái)在Debian上配置FTP服務(wù)器。(′?_?`)配置以下是配置一些簡(jiǎn)單的步驟：，，配置1(/ω＼). 安裝vsftpd:sudo apt install vsftp(′?｀)d，配置2. 創(chuàng )建FTP共享路徑：mkdir /ftp，配置3. 修改配置文件：nano /etc/vsftpd.conf,(??ヮ?)?*:???配置添加以下內容：listen=YES、listen_ipv6=NO、配置anonymous_e(?????)nable=(?_?;)NO、配置write_enable=YES。配置

什么是配置Chroot環(huán)境？

Chroot,即Change Root,是一種Linux系統下的技術(shù)??，通過(guò)(′▽?zhuān)?Ch??ro??ot,配置我們可以將一個(gè)進(jìn)程的根目錄更改為一個(gè)新的目錄，從而使得(de)該進(jìn)程認為ヽ(′?｀)ノ自己仍然在原來(lái)的配置根目錄下運行，(′?｀*)但實(shí)際上已經(jīng)切換到了新的配置目錄，這種技術(shù)可以用于實(shí)現安全的配置系統隔離、限制進(jìn)程訪(fǎng)問(wèn)外部文件系統等目的配置。

如何在Debian 10中配置Chroot環(huán)境？

1、安裝必要的軟件包：

sudo apt-get upd??atesudo apt-get install open='open'ssh-serversudo apt-get in┐(′?｀)┌staヽ(′▽?zhuān)?ノll ope(′?ω?`)nssh-client

2、創(chuàng )建一個(gè)新的用戶(hù)和組：

sudo groupadd ssh_userssudo useradd -m -g ssh_user(′?｀)s -s /usr/sbin/nologin ssh_user

sudo nano /etc/ssh/sshd_config

將以下內容添加或修改到配置(′；д；`)文件中：

X11Forwarding yesPass??wordAuthentication yesPubkeyAuthentication yesAuthorizedKeysFile .ssh/authorized_keys

保存并退出。

4、為新用戶(hù)設置密碼并生成

密鑰對：

sudo passwd ssh_user(′ω｀)ssh-( ?ヮ?)keygen -t rsa -b 4096 -f ~/ˉ\_(ツ)_/ˉ.ssh/id_rsa -N ""

5、將用戶(hù)的公鑰??添加到SSH服務(wù)器：

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keyschmod 600 ~/.ssh/author??ized_keyschown -R ssh_uヽ(′▽?zhuān)?/ser:ssh_users ~/.ssh/

6、重啟SSH服務(wù)：

sudo systemctl restart ssh

7ヽ(′ー｀)ノ、在De??bian 10中創(chuàng )建一??個(gè)新的目錄作為Chroot環(huán)境的根目錄：

sudo mkdir /var/chroot_env

8、將用戶(hù)的家目錄掛載到新創(chuàng )建的目錄上，并設置相應的權限：

sudo mount --bind ~/home/ssh_user /var/chroot_env/home/ssh_usersudo chown ssh_user:ssh_users /var/chroot_env/home/ssh_user -Rsudo chmod 700 /var/c??hroot_env/home/ssh_user -R

9、在Debian 10中創(chuàng )建一個(gè)新的systemd服務(wù)文件，用于管理Chroot環(huán)境：

sudo nano /etc/system??d/system/chroot.service

將以下內容添加到服務(wù)文件中：

[Unit]Description=Chroot environment for SSH user ssh_user and their home directory /var/chroot_env/home/ssh_userAfter=network.target syslog.target sshd.service dbus.service udev.service netd??ev.target remote-fs.target rsy(′?｀)slog.service timesyncd.service timezoneda??ta.service systemd-tmpfi??les-setup.service systemd-sysusers.device systemd-networkd-wait-online.service systemd-resolved.service systemd-logind.socket systemd-j(??ヮ?)?*:???ournald.socket systemd-udevd.socket systemd??-randomfile.socket systemd-nscd.socket systemd-cups-restart.socket cups-filter.socket cups-stateless-udev.socket dbus-daemon.socket dbus-ses??sion.so(′▽?zhuān)?cket dbus-x11-user.socket libvirtd.socket libvirtd-syste(′；ω；`)md.socket?? systemd-libvirtd-system(′▽?zhuān)?d.socket libvirtd-vcpuacヽ(′?｀)ノct.socket libvirtd-guestagent.socket libvirtd-storagebus.socket libvirtd-lxcbrctlhelper.socket libvirtd-lxcdumperhelper.socket libvirtヽ(′▽?zhuān)?/d-lxcpro??xyhelper.socket libvirtd-lxcviewヽ(′ー｀)ノerhelper.socket libvirtd-l???ibvirtd-systemd.socket libvirtd-qemuguesta( ?° ?? ?°)gent.socket libvirtd-spicehelper.sockeヽ(′▽?zhuān)?ノt libvirtd-spiceportal??helpe??r.socket systemd-networkm??anager-wait-online.(′?｀)service systemd-resolve@20-25 netw??orkManagerWaitOnline=true wai(′?ω?`)tfo(°o°)r=netw(′▽?zhuān)?ork.target dbus.service udev.service timesyncd.service timezonedata.service systemd-tmpfiles-setup.service systemd-sysusers.device systemd-networkd-wait-online.service systemd-resolved.service systemd-logind.socket systemd-journald.socke??t systemd-udevd.soc(′?｀*)ket systemd-ran??domfi??le.socket systemd-nscd.socket systemd-cups-restart.socket cups-filter.socket cups-stateless-udev.socket dbus-daemon.socket dbus-session.socket dbus-x11-user.ヽ(′▽?zhuān)?ノsocket libvirtd.socket libvirtd-systemd.socket systemd-libvirtd-syst??emd.socke??t libvirtd-┐(′д｀)┌vcpuacct.(′_ゝ`)socket libvirtd-guestagent.socket lib(╯‵□′)╯virtd-storˉ\_(ツ)_/ˉagebus.socket libvirtd-lxcbrctlhelper.socket libvirtd-lxcdumperhelper.socket libvirtd-lxcproxyhelper.socket li(′_｀)bvirtd-lxcviewerhelper.socket libvirtd-libvirtd-systemd.socket libvirtd-qemuguestagent.soc(′；ω；`)ket libvirtd-spicehelper.socket libvirtd-spic(???)eportalhelper.socket systemd-network??manager@20 service=networkManager waitfor=networkManager ser??vice=defaults wai??tfor=netwo(′_ゝ`)rkManager ser┐(′д｀)┌vice=firewallD waitfor=networkManager service=ufw waitfor=systemd-timesyncd servic???e=timesync waitfor=timesync servヽ(′▽?zhuān)?ノice=s??ystemd-tmpfiles service=syslog service=rsyslog service=sysstat service=kerneloopiei service=cronie service=anacron service=rtkit service=htop service=gnomepowertop service=gnomecalendario service=mateweather service=nautilus service=gnometodo service=gnomem???aps service=gnometerminal service=gnomecontrolcen?ter service=gnomesoftware service=gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME??/gnomeshell extension=$HOME/gnomeshell extension=$H(╯°□°)╯OME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnom(′?_?`)eshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell ext??ension=$HOME/gnom(′▽?zhuān)?)eshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell ext??ension=$HOME/gnomeshell extension=$HOME/gnomes(???)hell extension(?_?;)=$HOME/gnomeshell extension=$HOME/??gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell ex??tension=$HOME/gnomeshell extension=(°o°)$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshell extension=$HOME/gnomeshe(???)ll extension=$HOME/gnomeshell extension=$HOMEextensi(′?_?`)on=$HOMEexten??sion=$HOMEextension=$EXTENSIONcommand="/usr/bin/chroot --userspec=ssh_user:ssh_users --directory=%h %i" execReload=yes restart=on-failure status=restarted delaySec=5 startLimitIntervalSec=5 star??tLimitBurst=3 type=simple unit=chroot stateful user=%i group=%i environment="PATH=%PATH%??,LANG=%LA(′▽?zhuān)?NG%",NOEXECPROMPT HOME=%~ envFile="/etc/env(⊙_⊙)ironment&(′-ι_-｀)quot; timeoutStartSec=90 timeoutStopSec=60 restartSec=5 startLimitIntervalSec ofServiceType="si??mple" en???abled??CountMax="3" enab??ledCountMin="1&quヽ(′ー｀)ノot; enabledCountInc??r(//ω//)ement="1" disabled='disabled'CountMax="3" disabled="disabled"CountMin="1" disabled='disabled'CountIncrement="1">ExecStart=<ExecStart>%i</ExecSt(T_T)art>Restart=always<(//ω//)/Service>```
