ftp 22端口可以连接但是21端口连接不上  
是因为 /etc/vsftpd/nginx.config出现了问题

[root@imageServe myfile]# cd /etc/vsftpd
    [root@imageServe myfile]# cd /etc/vsftpd
    [root@imageServe vsftpd]# ls
    ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh
    [root@imageServe vsftpd]# vi vsftpd
    vsftpd.conf             vsftpd_conf_migrate.sh  
    [root@imageServe vsftpd]# vi vsftpd
    vsftpd.conf             vsftpd_conf_migrate.sh  
    [root@imageServe vsftpd]# vi vsftpd.conf
    [root@imageServe vsftpd]# service vsftpd restart
    Redirecting to /bin/systemctl restart  vsftpd.service
    [root@imageServe vsftpd]# ls
    ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh
    [root@imageServe vsftpd]# vi ftpusers
    [root@imageServe vsftpd]# vi user_list
    [root@imageServe vsftpd]# service vsftpd restart
    Redirecting to /bin/systemctl restart  vsftpd.service
    [root@imageServe vsftpd]#

vsftpd.config的正确配置

# 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).
    "vsftpd.conf" 131L, 5097C

然后在重新启动一下ftp

service vsftpd restart

然后再连接试试，如果还不行查看root是否被禁止了  
输入vi ftpusers

# Users that are not allowed to login via ftp
    #root // 这个地方root前要有#
    bin
    daemon
    adm
    lp
    sync
    shutdown
    halt
    mail
    news
    uucp
    operator
    games
    nobody

再查看vi 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 // 这个地方root前要有#
    bin
    daemon
    adm
    lp
    sync
    shutdown
    halt
    mail
    news
    uucp
    operator
    games
    nobody

然后再重新连接21端口试试
