1.安装vsftp
查看是否安装
rpm -q vsftpd
没有则安装
yum install -y vsftpd
查看vsftp服务状态
systemctl status vsftpd.service
开启vsftp
systemctl start vsftpd.service
2.配置vsftp.conf
vi /etc/vsftpd/vsftpd.conf # 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. # 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=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 userlist_deny=NO local_root=/var/public_root tcp_wrappers=YES use_localtime=YES allow_writeable_chroot=YES
添加ftp账号
useradd -d /var/www/html -g ftp -s /sbin/nologin opfan
设置密码
passwd opfan
设置ftp根目录和权限
chown -R opfan /var/www/html chmod -R 755 /var/www/html
编辑user_list，添加用户访问
vi /etc/vsftpd/user_list # 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 #新增用户 test
3.防火墙设置
防火墙添加ftp服务
firewall-cmd --permanent --zone=public --add-service=ftp firewall-cmd --reload
设置SElinux
getsebool -a | grep ftp [root@localhost ~]# setsebool -P ftpd_full_access on
4.重启vsftp服务
systemctl stop vsftpd.service systemctl start vsftpd.service systemctl status vsftpd.service
ps:针对腾讯云服务器还需如下修改
ftp协议传输文本有2中模式，被动和主动模式，在被动模式下无法通过fpt访问
解决方案有2种:
a.将客户端传输模式改为主动模式
b.在vsftp.conf新增如下内容
pasv_address=***.***.***.***( 外网ip) pasv_enable=YES pasv_min_port=10020 pasv_max_port=10040
腾讯云安全组需要开放10020-10040区间tcp端口
解决ftp登陆时间过长
vi /etc/vsftpd/vsftpd.conf reverse_lookup_enable=NO
