Next for execute apache and upload files

Model: GPT-5

Best practice → make ubuntu the owner and group www-data so Apache can also read/write/execute.

Step 1 — set owner & group

sudo chown -R ubuntu:www-data /var/www/html

Step 2 — give permissions

Allow:

• owner (ubuntu) = read/write/execute

• group (www-data) = read/execute (and write if needed)

sudo chmod -R 775 /var/www/html

STEP 3 — make sure apache runs as www-data

By default apache2 on ubuntu = www-data

Check:

grep -i '^user\|^group' /etc/apache2/envvars

Should show:

export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data

Final correct setup (recommended)

sudo chown -R ubuntu:www-data /var/www/html
sudo chmod -R 775 /var/www/html

This gives ubuntu = full access
and apache (www-data) = read/write/execute inside project dirs.

If you add new files via git / sftp

To automatically inherit permissions:

sudo find /var/www/html -type d -exec chmod g+s {} \;
