VSFTP是一个基于GPL发布的类Unix系统上使用的FTP服务器软件，它的全称是Very Secure FTP 从此名称可以看出来，编制者的初衷是代码的安全。
下面说说在CentOS 6.5_64位系统下安装VSFTP步骤
1.查看linux系统版本和内核信息
[root@vmware1 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@vmware1 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
2.关闭防火墙和selinux。
[root@vmware1 ~]# /etc/init.d/iptables stop
[root@vmware1 ~]# chkconfig iptables off
[root@vmware1 ~]# setenforce 0
3.安装vsftp软件包。
[root@vmware1 ~]# yum install -y vsftpd
先备份vsftpd的默认配置文件；
[root@vmware1 ~]# cd /etc/vsftpd/
[root@vmware1 vsftpd]# cp vsftpd.conf vsftpd.conf.bak
4.清空vsftpd.cong默认的内容。
root@vmware1 vsftpd]# >vsftpd.conf
5.修改后的内容为：
[root@vmware1 vsftpd]# cat 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=YES # # 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=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # The target log file can be vsftpd_log_file or xferlog_file. # This depends on setting xferlog_std_format parameter 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 # # The name of log file when xferlog_enable=YES and xferlog_std_format=YES # WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log #xferlog_file=/var/log/xferlog # # Switches between logging into vsftpd_log_file and xferlog_file files. # NO writes to vsftpd_log_file, YES to xferlog_file 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 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 tcp_wrappers=YES
11.重启vsftpd，然后查看端口是否开启。
[root@vmware1 ~]# service vsftpd restart
关闭 vsftpd： [确定]
为 vsftpd 启动 vsftpd： [确定]
这样就可以用系统原有用户进行登陆了
[root@vmware1 ~]# netstat -anpt | grep vsftpd
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 2191/vsftpd
12.在本地ftp服务器登陆测试。
[root@vmware1 ~]# ftp 127.0.0.1
Connected to 127.0.0.1 (127.0.0.1).
220 (vsFTPd 2.2.2)
Name (127.0.0.1:root): lhc
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> dir
227 Entering Passive Mode (127,0,0,1,149,179).
150 Here comes the directory listing.
226 Directory send OK.
ftp> mkdir hello
257 "/hello" created
ftp> dir
227 Entering Passive Mode (127,0,0,1,141,105).
150 Here comes the directory listing.
drwxr-xr-x 2 500 500 4096 Jan 16 15:27 hello
226 Directory send OK.
到此为止，VSFTP搭建完成，实验结束。
