使用php将图像上传到AWS EC2

Question

I'm trying to upload a file to a virtual machine in Amazon. and i have some questions.

I think i have to give (777) permissions to my server folder to be able to upload my file. if i don't it won't work. is this ok?

is it secure to give those permissions?

Answer 1

You don't need to make the file's permissions 777 in order to be able to write it into a directory. Instead, the directory needs to have permission to be written to by the user.

If you are running apache, the process runs as the user www-data and wherever you are trying to write the file to, must have write permissions by this user. If you are writing to /var/www/my_file_uploads , then try this:

chown -R www-data:www-data /var/www/my_file_uploads

Note that by doing this, you will be preventing others on your home machine from reading the file as well (unless you explicitly permit it).
