ftp连接21端口出现的问题的解决方案

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
