1.查看是否安装vsftp
[root@localhost ~]#rpm -qa|grep vsftpd
如果出现 vsftpd-2.2.2-13.el6_6.1.x86_64 则说明已经安装了vsftp。
如果没出现vsftpd等字段，则执行第二步；
2.安装vsftpd
[root@localhost ~]# yum -y install vsftpd
3.配置vsftpd.conf文件【/etc/vsftpd/vsftpd.conf】
# 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=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 userlist_deny=NO local_root=/var/www/html/ftp use_localtime=YES
4.新增FTP账号
[root@localhost ~]# useradd cookie-s /sbin/nologin [root@localhost ~]# passwd cookie
5.编辑user_list文件，允许新增账户访问FTP【也可以先删除原有的账户，再添加允许访问的FTP账户】
# vsftpd userlist # If userlist_deny=NO, only allow users in this file # If userlist_deny=YES (default), never allow users in this file, and # do not even prompt for a password. # Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers # for users that are denied. root bin daemon adm lp sync shutdown halt mail news uucp operator games nobody cookie
6.新建FTP访问根目录，并设置访问权限【目录名称已在vsftpd.conf中注明，如果该FTP能上传文件的话，需要将权限修改成777】
[root@localhost ~]# mkdir /var/www/html/ftp [root@localhost ~]# chown -R cookie /var/www/html/ftp [root@localhost ~]# chmod -R 755 /var/www/html/ftp
7.开启vsftpd服务
[root@localhost ~]# service vsftpd start
8.开机启动FTP服务
[root@localhost var]# chkconfig vsftpd on
