Linux cannot upload files

Problem:

Unable to upload files to the Linux host.

For example: We now want to upload file A to the /opt/software directory, but at this time we find that it cannot be uploaded.

[isea@redis99 software]$ ll
总用量 4664
-rw-r--r--. 1 root root 1547237 10月 28 07:25 redis-3.2.8.tar.gz
-rw-r--r--. 1 root root 3226139 10月 28 07:25 ruby-gems.tar.gz

Reason:

We use the isea user when connecting remotely, so we cannot download content to the root folder.

Solution:

1. Use the root account to connect and then upload;

2. Modify the owner of the /opt/software directory and then upload it.

[isea@redis99 opt]$ sudo chown -R isea:isea /opt/module/ /opt/software/ 
[isea@redis99 opt]$ ll 
总用量 8
drwxr-xr-x. 3 isea isea 4096 10月 28 07:27 module
drwxr-xr-x. 2 isea isea 4096 10月 28 07:27 software

If the root permissions of a general user are not configured, you can switch to the root user.
