生活随笔收集整理的這篇文章主要介紹了 linux下ftp服务阶段实验（3）小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

linux下ftp服務階段實驗（3）

3.??（1）匿名用戶的FTP根目錄是/ftp，只能下載，下載速度為100Kbps
????（2）本地用戶hello的FTP根目錄為/hello，可以上傳下載，家目錄被鎖定，下載速度為200Kbps
????（3）管理員root的FTP根目錄為/admin，可以上傳下載，家目錄不被鎖定，下載速度不限制
?????注意以上用戶的本地宿主目錄不要修改

1.修改vsftpd主配置文件

[root@localhost ~]# vim /etc/vsftpd/vsftpd.conf

#需要添加和修改的地方
chroot_local_user=YES??????????????????????#將本地用戶禁錮在自己的家目錄
chroot_list_enable=YES?????????????????????#列表中的用戶不被禁錮自己的家目錄
chroot_list_file=/etc/vsftpd/chroot_list???#定義列表文件路徑
user_config_dir=/etc/vsftpd/ftp????????????#定義用戶獨立配置文件的路徑

2.為不同的用戶建立獨立的配置文件

#編輯匿名用戶獨立配置文件

[root@localhost ~]# vim /etc/vsftpd/ftp/ftp [root@localhost ~]# cat /etc/vsftpd/ftp/ftp

anonymous_enable=YES??????#允許匿名用戶登錄
anon_root=/ftp????????????#定義匿名用戶根目錄
anon_upload_enable=NO?????#不允許匿名用戶上傳
local_max_rate=100000?????#最大下載速度為100k

#編輯用戶hello獨立配置文件

[root@localhost ~]# vim /etc/vsftpd/ftp/hello [root@localhost ~]# cat /etc/vsftpd/ftp/hello

local_root=/hello????????????#定義用戶的根目錄
write_enable=YES?????????????#允許用戶上傳
download_enable=YES????????????#允許用戶下載
local_max_rate=200000??????????#最大下載速度為200

#編輯用戶root獨立配置文件

[root@localhost ~]# vim /etc/vsftpd/ftp/root [root@localhost ~]# cat /etc/vsftpd/ftp/root

local_root=/admin??????#定義用戶的根目錄
write_enable=YES???????#允許用戶上傳
download_enable=YES???#允許用戶下載
local_max_rate=0???????#無限速下載

3.創建用戶ftp根目錄并創建一些標識性文件。

#創建3個用戶的ftp家目錄

[root@localhost /]# mkdir ftp hello admin

#在家目錄新建一些標識性空文件

[root@localhost /]# touch ftp/ftp [root@localhost /]# touch hello/hello [root@localhost /]# touch admin/admin

#給hello文件添加寫權限

[root@localhost /]# chown o+w hello/

4.添加hello用戶并重啟vsftpd服務

[root@localhost ~]# useradd hello [root@localhost ~]# echo "123"|passwd hello --stdin

Changing?password?for?user?hello.
passwd:?all?authentication?tokens?updated?successfully.

#把以下兩個文件中的root注釋掉，不然root登錄不了ftp

[root@localhost ~]# vim /etc/vsftpd/ftpusers [root@localhost ~]# vim /etc/vsftpd/user_list

[root@localhost ~]# service vsftpd restart

Shutting?down?vsftpd:??????????????????????????????????[FAILED]
Starting?vsftpd?for?vsftpd:????????????????????????????[??OK??]

5.驗證用戶登錄

#測試匿名用戶登錄

[root@localhost /]# ftp 192.168.1.88
