Why can't linux upload files?

What I want to share with you today is why linux can't upload files. I believe many people don't know much about it. In order to let you know more about linux, I summarized the following contents for you. Let's look down together. I'm sure you'll get something.

Question:

Unable to upload file to Linux host.

For example, we now want to upload the A file to the / opt/software directory, but we find that we can't upload it at all.

[isea@redis99 software] the total amount of $ll is 4664 RW Murray. 1 root root 1547237 October 28 07:25 redis-3.2.8.tar.gz-rw-r--r--. 1 root root 3226139 October 28 07:25 ruby-gems.tar.gz

Reason:

When we connect remotely, we use the isea user, so we cannot download the content to the root folder.

Solution:

1. Use a root account to connect, and then upload

2. Modify the owner of the / opt/software directory before uploading it.

[isea@redis99 opt] $sudo chown-R isea:isea / opt/module/ / opt/software/ [isea@redis99 opt] $ll total dosage 8drwxr-xr-x. 3 isea isea 4096 October 28 07:27 moduledrwxr-xr-x. 2 isea isea 4096 October 28 07:27 software

If you do not have root permissions for the general user, you can switch to the root user.
