（1）安装vsftp：
[[email protected] ~]$ sudo yum install vsftpd #sudo 给普通用户添加root权限，用root用户登录不用使用sudo
（2）完成安装，配置vsftp：
vsftp的配置文件在：/etc/vsftpd/目录下：
vsftpd.conf //vsftp的配置文件
user_list、ftpusers //禁止登录vsftp的用户名单
[[email protected] vsftpd]$ sudo vim /etc/vsftpd/vsftpd.conf #打开配置文件 # 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? (Beware - allowed by default if you comment this out). anonymous_enable=NO #是否允许匿名用户登录 # # Uncomment this to allow local users to log in. local_enable=YES #是否允许本地用户登录 # # Uncomment this to enable any form of FTP write command. write_enable=YES #登录用户是否具有文件的写权限 # # Default umask for local users is 077.

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 #是否允许使用ASCII格式来上传下载文件 # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. #在ftp服务器中设置欢迎登陆 # # 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 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(). #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 # # When "listen" directive is enabled, vsftpd runs in standalone mode and # listens on IPv4 sockets. This directive cannot be used in conjunction # with the listen_ipv6 directive. listen=YES # # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6 # sockets, you must run two copies of vsftpd with two configuration files. # Make sure, that one of the listen options is commented !! #listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES //用户列表中的用户是否允许登录FTP服务器,默认是不允许 tcp_wrappers=YES
（3）连接ftp服务器：
windows环境下：
Linux环境下：
1、连接ftp服务器：
格式：ftp [hostname| ip-address] a)在linux命令行下输入： ftp 192.168.1.1 b)服务器询问你用户名和密码，分别输入用户名和相应密码，待认证通过即可。
2、下载文件
下载文件通常用get和mget这两条命令。
a) get
格式：get [remote-file] [local-file]
将文件从远端主机中传送至本地主机中。
如要获取远程服务器上/usr/your/1.htm，则
get /usr/your/1.htm
b) mget
格式：mget [remote-files]
从远端主机接收一批文件至本地主机。
如要获取服务器上/usr/your/下的所有文件，则
ftp> cd /usr/your ftp> mget *.*
3、上传文件
a) put
格式：put local-file [remote-file]
将本地一个文件传送至远端主机中。
如要把本地的1.htm传送到远端主机/usr/your,并改名为2.htm
ftp> put 1.htm /usr/your/2.htm
b) mput
格式：mput local-files
将本地主机中一批文件传送至远端主机。
如要把本地当前目录下所有html文件上传到服务器/usr/your/ 下
ftp> cd /usr/your ftp> mput *.htm
4、断开连接
ftp> bye
