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
