# 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. # When SELinux is enforcing check for SE bool ftp_home_dir 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. # When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access #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 # # Activate logging of uploads/downloads. 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 # # You may override where the log file goes if you like. The default is shown # below. #xferlog_file=/var/log/xferlog # # 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 # # 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. The vsftpd.conf(5) man page explains # the behaviour when these options are disabled. # 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(). # (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 # (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=NO # # 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. # Make sure, that one of the listen options is commented !! listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES

建立用户文件
$ vi /etc/vsftpd/virtusers
添加内容
test
123456
yma16
123456
生成用户数据
查询安装db4
$ yum search db4 $ yum install -y compat-db47.x86_64
生成db文件
db_load -T -t hash -f /etc/vsftpd/virtusers /etc/vsftpd/virtusers.db
指定用户读取文件
$ chmod 600 /etc/vsftpd/virtusers.db
修改/etc/pam.d/vsftpd文件
备份源文件
$ cp /etc/pam.d/vsftpd /etc/pam.d/vsftpd.bak
修改 /etc/pam.d/vsftpd
$ vim /etc/pam.d/vsftpd
添加
auth sufficient/lib64/security/pam_userdb.so db=/etc/vsftpd/virtusers
account sufficient/lib64/security/pam_userdb.so db=/etc/vsftpd/virtusers
创建用户及用户目录
创文件夹共享
$ mkdir -p /home/vsftpd
用户登录设置false
对应配置文件中的
guest_username=vsftp
user_config_dir=/etc/vsftpd/vconf
添加用户vsftpd
$ useradd vsftpd -d /home/vsftpd -s /bin/false $ chown -R vsftpd:vsftpd /home/vsftpd
用户配置文件
对应配置文件中的
user_config_dir=/etc/vsftpd/vconf
根据之前添加的用户文件配置
$ mkdir /etc/vsftpd/vconf $ cd /etc/vsftpd/vconf $ touch test yma16
建立用户根目录,编写配置文件
$ mkdir -p /home/vsftpd/test $ vim test $ mkdir -p /home/vsftpd/test $ vim yma16
添加内容,可读写
local_root=/home/vsftpd/test/
write_enable=YES
anon_world_readable_only=NO
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
防火墙配置(添加ftp)
查看防火墙,若未开启则打开防火墙
$ systemctl status firewalld $ systemctl start firewalld
出现mask
$ systemctl unmask firewalld
$ firewall-cmd --permanent --zone=public --add-service=ftp $ firewall-cmd --reload $ getsebool -a | grep ftp $ setsebool -P ftpd_full_access on
重启vsftpd
$ systemctl stop vsftpd.service $ systemctl start vsftpd.service $ systemctl status vsftpd.service
通过ftp访问文件
在/home/vsftpd/test/共享文件
创建一个ftp_file文件夹
$ mkdir /home/vsftpd/test/ftp_file
访问我的centos的ftp://+ip
需要验证登录
使用test或者yma16账号登录
但是发现所有人都能访问,有点小问题,共享文件夹位置未存在/home/vsftpd/test/ftp_file
问题解决中……
