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]# lsftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh[root@imageServe vsftpd]# vi vsftpdvsftpd.conf             vsftpd_conf_migrate.sh  [root@imageServe vsftpd]# vi vsftpdvsftpd.conf             vsftpd_conf_migrate.sh  [root@imageServe vsftpd]# vi vsftpd.conf[root@imageServe vsftpd]# service vsftpd restartRedirecting to /bin/systemctl restart  vsftpd.service[root@imageServe vsftpd]# lsftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh[root@imageServe vsftpd]# vi ftpusers[root@imageServe vsftpd]# vi user_list[root@imageServe vsftpd]# service vsftpd restartRedirecting 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_dirlocal_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_accessanon_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#bindaemonadmlpsyncshutdownhaltmailnewsuucpoperatorgamesnobody

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#bindaemonadmlpsyncshutdownhaltmailnewsuucpoperatorgamesnobody

然后再重新连接21端口试试
