（1）安裝vsftp：
[centos@localhost ~]$ sudo yum install vsftpd #sudo 給普通用戶添加root權限，用root用戶登錄不用使用sudo
（2）完成安裝，配置vsftp：
vsftp的配置文件在：/etc/vsftpd/目錄下：
vsftpd.conf //vsftp的配置文件
user_list、ftpusers //禁止登錄vsftp的用戶名單
[centos@localhost vsftpd]$ sudo vim /etc/vsftpd/vsftpd.conf #打開配置文件 # Example config file /etc/vsftpd/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. # # Allow anonymous FTP?

（3）連接ftp服務器：
windows環境下：
Linux環境下：
1、連接ftp服務器：
格式：ftp [hostname| ip-address] a)在linux命令行下輸入： ftp 192.168.1.1 b)服務器詢問你用戶名和密碼，分別輸入用戶名和相應密碼，待認證通過即可。
2、下載文件
下載文件通常用get和mget這兩條命令。
a) get
格式：get [remote-file] [local-file]
將文件從遠端主機中傳送至本地主機中。
如要獲取遠程服務器上/usr/your/1.htm，則
get /usr/your/1.htm
b) mget
格式：mget [remote-files]
從遠端主機接收一批文件至本地主機。
如要獲取服務器上/usr/your/下的所有文件，則
ftp> cd /usr/your ftp> mget *.*
3、上傳文件
a) put
格式：put local-file [remote-file]
將本地一個文件傳送至遠端主機中。
如要把本地的1.htm傳送到遠端主機/usr/your,並改名爲2.htm
ftp> put 1.htm /usr/your/2.htm
b) mput
格式：mput local-files
將本地主機中一批文件傳送至遠端主機。
如要把本地當前目錄下所有html文件上傳到服務器/usr/your/ 下
ftp> cd /usr/your ftp> mput *.htm
4、斷開連接
ftp> bye
