Permission denied inside /var/www/html when creati

问题:

UPDATE** The screenshot is within atom, but when I navigate to the directory using the file explorer, and right click, the option to rename or create a new folder are restricted and I cannot click on them.

I just finished setting up the LAMP stack on my fresh UBUNTU 18.04 installation. I have everything working, the default /var/www/html/index.html page from Apache2 is being served on localhost, no port forwarding or any unique domain name, i just wanna run this on my network from my computer for now.

If there is a simple way to create multiple websites and easily choose which folder to serve than that's fine, but I want to serve just one website for now.

When I go to my /var/www/html folder and try to edit the index.html file it says permission denied. What do I need to do in order to work inside this directory for the remaining time that I am building the website. I am signed in as the root user on my system.

Also, if I do change permissions to allow me to work in this directory, what does it mean for people trying to access my server if it was available to the public. (RIGHT NOW JUST ON LOCALHOST).

Lemme know if you need more info or explanation thanks!

回答1:

sudo chown -R $USER:$USER /var/www

this works, it changes the owner to my user instead of root user. I still don't understand because my user already had sudo rights and all those permissions. It was the user I created during the ubuntu18.04 setup, so there shouldn't be an issue, or idk.

回答2:

The permission error is occurring because the folder does not have the rights and rights are reserved with different user. (you can inspect this by doing ls -l folderName)

The solution for your problem can be handled in different ways following are the few :

WAY1:

1. Find out who is running apache by running the command apachectl -S
2. Locate the user name (say www-data)
3. Change the ownership of your folder as chown -R www-data:www-data /var/www/html (this will allow only your apache to play with files)
4. Run the following command ln -s /var/www/html /home/username/html (this will create a soft link for your folder, where you can edit/delete/read which will reflect on your apache)

WAY2:

1. goto /var/www/
2. sudo chown -R www-data:${USER} html (Now both apache and your loged-in user will have rights to play with file).

回答3:

File ownership issues can be fixed at the command line by typing:

sudo chmod 777 /var/www/html -R

One caveat from turnkeyLinux.com:

Changing file permissions is a trade off (often increasing security reduces user-friendliness and/or usability). For security 'best practice' only the folders that require write access by the webserver should be owned by the webserver. If your webserver has write access everywhere and your server is compromised it makes it easier to hack your WordPress install) but for ease of use giving the webserver ownership should resolve all your issues...

This article on Understanding File Permissions was great, too.

回答4:

Edit the file as root. Or better yet fix your permissions so you don’t have to worry.

回答5:

This will help you.

sudo chgrp -R www-data /var/www/html
sudo gpasswd -a username www-data
sudo chmod -R 777 /var/www/html
