将上面代码复制粘贴到一个.sh文件保存,将文件复复制到虚拟及中.
执行已下操作:
1.安装 （命令执行：sh xxx.sh）

2.添加ftp用户 （命令执行：sh xxx.sh add）

3.卸载vsftpd （命令执行：sh xxx.sh uninstall）

执行完以上步骤并不能完全实现上传操作
需要配置pasv设置
在/etc/vsftpd/vsftpd.conf
最后部分添加

pasv_enable=YES
pasv_max_port=30010
pasv_min_port=30000

防火墙配置:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 30000:30010 -j ACCEPT

ps:如果用windows客户端连接出现”500 OOPS: cannot change directory:/home/xxx”
修改selinux

getsebool -a | grep ftp 

执行上面命令，再返回的结果看到两行都是off，代表，没有开启外网的访问

....   

ftpd_full_access off   

....  

....  

ftp_home_dir off 

只要把上面都变成on就行

执行

setsebool -P ftpd_full_access 1   

setsebool -P ftp_home_dir  1 

重启vsftpd

service vsftpd restart
