Permissions on /var/www/html for uploading web site files via SFTP

Hi,

I’ve installed nginx successfully on an Ubuntu instance here at DigitalOcean. The index.html page (in /var/www/html) displays appropriately: “Welcome to nginx on Debian.”

Now I want to upload some files via Cyberduck (sftp) to “duplicate” my current web site currently hosted elsewhere: chestradiologists.org

But I cannot because I don’t have the appropriate permissions. (I created a new user with sudo permissions after I created the Ubuntu VPS.)

Via Cyberduck, I see the following for /var/www/html (all these directories):

rwxr-xr-x (755)

        Read      Write     Execute

Owner Y Y Y
Group Y No Y
Others Y No Y

Owner 0
Group 0

……

I’m the only user that will upload files I create with Octopress on my Mac.

How do I change the ownership/permissions to best accomplish this ?

I have a rudimentary understanding of Unix permissions :-(

So, please explain with some detail if possible.

Thanks!

Update: the following seems to have worked:

  1. Establish a [new directory] at /var/www

  2. Change the directory owner and group:
    sudo chown www-data:www-data /var/www/[new directory]

  3. allow the group to write to the directory with appropriate permissions:
    sudo chmod -R 775 /var/www

  4. Add myself to the www-data group:
    sudo usermod -a -G www-data [my username]

Logout and login again.

Thanks.

I believe the owner is www-data? 755 will allow www-data (Webserver) to create and edit, as you’re not the owner you cannot edit it, I’ve simply found doing chown ben:www-data /var/www -R will allow you and the webserver owner permissions which gives you all access to that directory.

    Hi,

    Can you please explain the difference between what you’ve recommended and the following approach:

    ....

    Add myself to the www-data:

    sudo usermod -a -G www-data [myusername]

    .......

    Then, recursively grant group write permissions to the /var/www/html directory:

    sudo chmod -R g+w /var/www/html

    ....

    Do you agree with the latter approach ?

    Thanks!

    Howard
