1、rpm -qa | grep vsftpd 来查看是否安装相应的包
2、如果没有,yum -y install vsftpd 来安装
3、修改配置vsftpd.conf
默认配置
根据默认配置给出中文注释
# Example config file /etc/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. # # # Run standalone? vsftpd can run either from an inetd or as a standalone # daemon started from an initscript. listen=YES (绑定到listen_port指定的端口,既然都绑定了也就是每时都开着的,就是standalone模式) # # This directive enables listening on IPv6 sockets. By default, listening # on the IPv6 “any” address (::) will accept connections from both IPv6 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6 # sockets. If you want that (perhaps because you want to listen on specific # addresses) then you must run two copies of vsftpd with two configuration # files. #listen_ipv6=no # # Allow anonymous FTP? (Disabled by default). anonymous_enable=NO (接受匿名用户,默认无密码请求) # # Uncomment this to allow local users to log in. local_enable=YES (接受本地用户) # # Uncomment this to enable any form of FTP write command. write_enable=YES (上传总开关) # # 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 (本地用户新增档案的权限) # # 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 (允许匿名用户上传文件) # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES (允许匿名用户创建新目录) # # Activate directory messages – messages given to remote users when they # go into a certain directory. dirmessage_enable=YES (允许为目录配置显示信息,显示每个目录下面的message_file文件的内容) # # If enabled, vsftpd will display directory listings with the time # in your local time zone. The default is to display GMT. The # times returned by the MDTM FTP command are also affected by this # option. use_localtime=YES # # Activate logging of uploads/downloads. xferlog_enable=YES (开启日记功能 ) # # 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 (所有匿名上传的文件的所属用户将会被更改成chown_username) #chown_username=whoever (匿名上传文件所属用户名) # # You may override where the log file goes if you like. The default is shown # below. xferlog_file=/var/log/vsftpd.log (日志文件位置 ) # # If you want, you can have your log file in standard ftpd xferlog format. # Note that the default log file location is /var/log/xferlog in this case. #xferlog_std_format=YES (使用标准格式 ) # # You may change the default value for timing out an idle session. #idle_session_timeout=600 (空闲连接超时 ) # # You may change the default value for timing out a data connection. #data_connection_timeout=120 (数据传输超时 ) # # 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 (当服务器运行于最底层时使用的用户名) # # 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 (允许使用”async ABOR”命令,一般不用,容易出问题) # # 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 (管控是否可用ASCII 模式上传。默认值为NO) #ascii_download_enable=YES (管控是否可用ASCII 模式下载。默认值为NO) # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. (login时显示欢迎信息.如果设置了banner_file则此设置无效) # # You may specify a file of disallowed anonymous e-mail addresses. Apparently # useful for combatting certain DoS attacks. #deny_email_enable=YES (如果匿名用户需要密码,那么使用banned_email_file里面的电子邮件地址的用户不能登录) # (default follows) #banned_email_file=/etc/vsftpd.banned_emails (禁止使用匿名用户登陆时作为密码的电子邮件地址) # # You may restrict local users to their home directories. See the FAQ for # the possible risks in this before using chroot_local_user or # chroot_list_enable below. chroot_local_user=YES # # 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(). # (Warning! chroot’ing can be very dangerous. If using chroot, make sure that # the user does not have write access to the top level directory within the # chroot) #chroot_local_user=YES #chroot_list_enable=YES (如果启动这项功能,则所有列在chroot_list_file中的使用者不能更改根目录) # (default follows) #chroot_list_file=/etc/vsftpd.chroot_list (定义不能更改用户主目录的文件) # # 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 (是否能使用ls -R命令以防止浪费大量的服务器资源) # # Customization # # Some of vsftpd’s settings don’t fit the filesystem layout by # default. # # This option should be the name of a directory which is empty. Also, the # directory should not be writable by the ftp user. This directory is used # as a secure chroot() jail at times vsftpd does not require filesystem # access. secure_chroot_dir=/var/run/vsftpd/empty # # This string is the name of the PAM service vsftpd will use. pam_service_name=vsftpd (定义PAM 所使用的名称,预设为vsftpd) # # This option specifies the location of the RSA certificate to use for SSL # encrypted connections. rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key ssl_enable=NO # # Uncomment this to indicate that vsftpd use a utf8 filesystem. #utf8_filesystem=YES
过滤配置文件多余注释
过滤掉那些注释,以便我们日后修改配置,大家可以删除vsftpd.conf内容,拷贝以下:
anonymous_enable=YES local_enable=YES write_enable=YES local_umask=022 #anon_upload_enable=YES #anon_mkdir_write_enable=YES dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES #chown_uploads=YES #chown_username=whoever #xferlog_file=/var/log/vsftpd.log xferlog_std_format=YES #idle_session_timeout=600 #data_connection_timeout=120 #nopriv_user=ftpsecure #async_abor_enable=YES #ascii_upload_enable=YES #ascii_download_enable=YES #ftpd_banner=Welcome to blah FTP service. #deny_email_enable=YES #banned_email_file=/etc/vsftpd/banned_emails #chroot_list_enable=YES #chroot_list_file=/etc/vsftpd/chroot_list #ls_recurse_enable=YES listen=YES #listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES
4、修改默认访问
/etc/vsftpd/vsftpd.conf:vsftpd 的核心配置文件,在找到anonymous_enable这个配置项,默认是YES,修改成NO,表示不允许匿名用户登录
/etc/vsftpd/ftpusers:用于指定哪些用户不能访问FTP 服务器。 黑名单,删除root后可以用root登录
/etc/vsftpd/user_list:指定允许使用vsftpd 的用户列表文件。 白名单,删除root后可以用root登录
5、 systemctl start vsftpd.service 启动vsftp服务,
systemctl status vsftpd.service 查看ftp服务的运行状态
systemctl restart vsftpd.service 重启vsftpd服务
6、关闭防火墙
centoos 7操作为systemctl stop firewalld.service
centoos 6操作位service stop iptables;
7、如果报错
进入控住面板-》程序-》启动或关闭Windows功能
勾选,然后确定。
8、如果还是连接不上,进入控制面板-》网络和internet-》internet
把 √ 取消,点确定。
