Linux ftp 上传文件 提示 Permission denied 解决办法

■前言

使用bat脚本直接上传文件，到Linux（Ubuntu）中。

putFile.bat

---------

start ftp -v -i -s:"myFtp.txt" 192.168.131.128

---------

myFtp.txt

---------

sxz001
myLinuxUserPassword
cd /srv/ftp/
cd /home/sxz001/myJava
ls
lcd C:\sxz\MyJava
binary
put HelloWorld.class

---------

上传文件时，出现如下问题

 Permission denied. 

 

■解决办法 

1.修改ftp服务的配置文件

sudo su -
cd /etc
vi vsftpd.conf
-----
#write_enable=YES
↓
write_enable=YES
-----

2.重新启动ftp服务
ps -e | grep ftp
service vsftpd stop
ps -e | grep ftp
service vsftpd start

3.文件夹权限问题

在这个类子中，我们上传目标的文件夹的所有者，

就是ftp登陆的用户，所有OK，

如果不是，可以修改权限为777，

但是一般不建议这么做，我们可以先把文件复制到个人目录下，

然后使用cp命令，复制文件到你想要的位置，

如，下面类子中，tomcat安装时的操作方法

■补足说明

无需修改，anonymous_enable

#接受匿名用户
anonymous_enable=YES

------------------------------------

如果修改为YES，则表明接受匿名用户，是不安全的。

 

■查看效果

运行刚才上传的class文件

反编译以上字节码

javap -v HelloWorld.class
