安装vsftpd的服务器相关软件
安装vsftpd服务器和客户端sudo yum install ftp vsftpd
安装一个加密工具
sudo yum install libdb-utils.x86_64
配置vsftpd
创建vsftpd的登录用户和主目录sudo useradd -d /home/myftp -s /sbin/nologin myftp(myftp是ftp的登录用户,替换成你自己的用户)
修改相应的密码
passwd myftp,
创建vsftpd虚拟用户
sudo touch /etc/vsftpd/vftpuser.txt
用户1 用户1密码 用户2 用户2密码 ......
sudo db_load -T -t hash -f /etc/vsftpd/vftpuser.txt /etc/vsftpd/vftpuser.db
4. 添加vsftpd的虚拟用户的验证
sudo vim /etc/pam.d/vsftpd
把account和auth替换了
session optional pam_keyinit.so force revoke #auth required pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed #auth required pam_shells.so #auth include password-auth #account include password-auth auth required pam_userdb.so db=/etc/vsftpd/vftpuser account required pam_userdb.so db=/etc/vsftpd/vftpuser session required pam_loginuid.so session include password-auth
修改vsftpd的配置文件vsftpd.conf
sudo vim /etc/vsftpd/vsftpd.conf
下面的文件删除了注释
# 是否运行匿名登录(NO) anonymous_enable=NO # 是否允许本地用户登录 local_enable=YES # 允许ftp的任何写方式 write_enable=YES # 文件创建只有的权限是755=(777-022) local_umask=022 # 是否允许匿名用户上传文件 #anon_upload_enable=YES # 是否允许匿名用户创建文件或者删除文件 #anon_mkdir_write_enable=YES # 用户进入目录信息提示 dirmessage_enable=YES # 是否允许vsftp的日志 xferlog_enable=YES # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # #chown_uploads=YES #chown_username=whoever # 日志文件的路径 xferlog_file=/var/log/xferlog # 日志文件的格式 xferlog_std_format=YES # #idle_session_timeout=600 # #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(). # (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. # 只监听ipv4的地址 listen=YES # # 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 # 下面是自己添加的 anon_root=/home/pageftp/open virtual_use_local_privs=YES guest_enable=YES guest_username=pageftp # 虚拟用户的配置文件(可以对每一个虚拟用户进行单独的权限配置) user_config_dir=/etc/vsftpd/vconf/ chroot_local_user=YES allow_writeable_chroot=YES
创建虚拟用户的权限配置
sudo mkdir /etc/vsftpd/vconf/
touch 用户1 用户2 ……
vim 用户1
cmds_allowed=ABOR,ACCT,APPE,CWD,CDUP,DELE,HELP,LIST,MODE,MDTM,MKD,NOOP,NLST,PASS,PASV,PORT,PWD,QUIT,REIN,RETR,RMD,RNFR,RNTO,SITE,SIZE ,STOR,STAT,STOU,STRU,SYST,TYPE,USER write_enable=yes download_enable=yes anon_upload_enable=yes anon_mkdir_write_enable=yes anon_other_write_enable=yes anon_world_readable_only=no
启动vsftpd服务
sudo systemctl enable vsftpd
sudo service vsftpd start
window用户访问vsftpd服务
添加网络映射接着下一步……然后完成即可,然后会提示你登录,填写相应的虚拟的vsftp的用户名和密码就可以完成登录了。就可以想操作本地文件夹一样操作!
