This is a repost of an "off-topic" question on stackoverflow.

My scenario is:

I created a user and added that user to sudoers:

visudo
user ALL=(ALL) ALL

Then

sudo adduser user www-data

and

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

Did a service restart, then tried:

scp file user@ip:/var/www

Permission denied

The permissions I had applied for folders then files were (not wp-config.php or .htaccess):

drwxr-xr-x
-rw-rw-r--

I tried:

sudo chmod -R g+w /var/www
I was then able upload files to /var/www, but this set permissions to 775, so I ran:

find /var/www -type d -exec chmod 755 {} \;

Now I can edit files but not write to the folder via SFTP or SSHFS etc.

My question now is:

How do I write to /var/www without compromising security?

The sudo change affects only commands that you run with sudo command. Therefore it has no effect in this case.

I would prefer making user the owner of all files in /var/www. Then, you can chmod 777 all the directories and chmod 666 all the files that WP needs write access to. With this, if someone exploits a security issue in WP, he cannot overwrite WP files that easily.

Alternatively you can change the owner to www-data for files / directories WP needs write access to. However, this way user can not write to those files / directories.

If your server filesystem supports ACLs, you can add an ACL to /var/www which gives write permission for some other user than the owner. This can be achieved with setfacl command.
