linux FTP Connection refused

ftp> open 192.168.2.163
ftp: connect: Connection refused

解決辦法：

[root@localhost apps]# vsftpd /etc/vsftpd/vsftpd.conf &
[1] 30890
#

再次FTP問題已經解決
如果有下面的問題，說明ftp服務沒有裝，可以yum重裝后再試：

[root@localhost apps]# vsftpd /etc/vsftpd/vsftpd.conf &
# -bash: vsftpd: command not found
[1]+  Exit 127                vsftpd /etc/vsftpd/vsftpd.conf
[root@localhost apps]# yum install vsftpd

如果還報下面的錯：
530 Permission denied.
Login failed
說明root權限被禁

[root@localhost apps]# ftp 10.xxx.xxx.xxx
Connected to 10.xxx.xxx.xxx
220 (vsFTPd 2.0.5)
530 Please login with USER and PASS.
530 Please login with USER and PASS.
KERBEROS_V4 rejected as an authentication type

root被禁用，可以修改下面兩個地方

[root@localhost apps]# vi /etc/vsftpd/ftpusers

# Users that are not allowed to login via ftp
#root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator

[root@localhost apps]# vi /etc/vsftpd/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.

然后重啟ftp:

# /sbin/service vsftpd restart
