Solution to ftp failure to connect and log in to linux

1. First install vsftpd

Command:

yum -y install vsftpd

then start the service:

service vsftpd start

2. Turn off the firewall

1) It will take effect after restarting

Open:

chkconfig iptables on

Close:

chkconfig iptables off

2) Effective immediately, invalid after restart

Open:

service iptables start

Close:

service iptables stop

3. By default, vsftp does not allow root users to log in. You can Solve this problem by modifying the restrictions

首先找到vsftp的配置目录
[root@localhost vsftpd]# pwd
/etc/vsftpd
[root@localhost vsftpd]# ls
chroot_list  ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh
[root@localhost vsftpd]#

修改
[root@localhost vsftpd]# cat ftpusers
# Users that are not allowed to login via ftp
#root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody

修改
[root@localhost vsftpd]# cat 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

上面这个两个就是默认情况下vsftp不允许使用的账号列表，讲文件中root删除，或者前面加个#号 重启一下vsftpd 服务 即可

4. Change the enforcing mode in /etc/selinux/config to disabled, then restart
