首先使用命令查看，系统内是否安装了vsftp
[root@instance_290388 down]# rpm -qa |grep vsftp
如果没有安装，使用命令，进行安装
[root@instance_290388 down]# yum -y install vsftpd
安装完成后，命令进入文件夹
[root@instance_290388 down]# cd /etc/vsftpd/
修改vsftp配置文件
[root@instance_290388 vsftpd]# vi vsftpd.conf
将vsftp.conf内容，替换成如下的内容
# 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. # 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 Hello KanYun. # # 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.

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 #pasv_enable=NO allow_writeable_chroot=YES pam_service_name=vsftpd userlist_enable=NO tcp_wrappers=YES userlist_file=/etc/vsftpd/user_list userlist_enable=YES userlist_deny=YES #此设置表示ftp用户登录之后进入哪个目录，跟用户主目录一致 local_root=/data/kanyun tcp_wrappers=YES use_localtime=YES
添加Ftp用户
#颜色标注为新增的用户名
[root@instance_290388 vsftpd]# useradd -d /data/kanyun kanyun #增加用户kanyun，并制定test用户的主目录为/data/kanyun 与上面颜色标注的路径一致
设置用户密码
[root@instance_290388 vsftpd]# passwd kanyun
启动vsftp
#注意关闭防火墙
[root@instance_290388 vsftpd]# service vsftpd start
启动ftp之后，建议使用命令行登录ftp，不建议直接使用xftp登录ftp，因为使用xftp登录ftp，报错的话看不到报错信息，使用命令行登录ftp，方法如下：
可以看到，使用命令行，可以很清楚自己配置的错误，然后就可以一一解决了！
删除用户使用命令
#在root用户下 [root@instance_290388 vsftpd]# userdel -r kanyun #在普通用户下 [root@instance_290388 vsftpd]# sudo userdel -r kanyun
卸载vsftp命令
[root@instance_290388 vsftpd]# rpm -e vsftpd
这两天又在Ubuntu上安装vsftp，Ubuntu的vsftp的配置文件都在/etc目录下，当然重点不是这个：
重点是这样的，我新增了一个用户，并设置密码，登陆Ftp老是报错
530 Login incorrect.
但是我的配置没有问题啊，老用户也是可以登陆的，于是我把vsftp卸载了，再新增用户，再装vsftp，结果还不行，在网上各种找答案，网上说改vsftp.conf的都不行，删用户，再新增用户，弄了差不多一个星期，后来想了想，因为之前新增用户图方便把用户密码设置成跟用户名一样了，所以想改一下，把密码改成了别的，结果一实验就等成功了。但是之前给用户设置密码，它也没有提示不让设置成跟用户名一样啊，结果我又把密码改成了跟用户名一样，又登不上去了 还是530 Login incorrect. 晕！
所以记录一下，看来在linux里设置密码真的小心了：用户名不要跟密码设置成一样
