The stream or file "/var/www/html/myscipt/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied

Hello! I uploaded script on the var/www/html document root, configured the virtual host on /etc/apache2/sites-available/000-default.conf by changing the document root from

DocumentRoot /var/www/html to DocumentRoot /var/www/html/myscript/public according to the docummentation of the script i bought.

Also, configured the /etc/apache2/apache2.conf by changing:

<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory>

to

<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>

Then restart apache using the command: sudo systemctl restart apache2

But before then I have created custom virtual host following the guide on this article:

https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-ubuntu-18-04

Because of this advice by the writer below on that article:

“Apache on Ubuntu 18.04 has one server block enabled by default that is configured to serve documents from the /var/www/html directory. While this works well for a single site, it can become unwieldy if you are hosting multiple sites. Instead of modifying /var/www/html, let’s create a directory structure within /var/www for our your_domain site, leaving /var/www/html in place as the default directory to be served if a client request doesn’t match any other sites”.

After that, I uploaded the file/script on the document root of the custom virtual host I created following the above article. When I visited the site the script I uploaded appear on the browser. because of that, I deleted the custom virtual host directory from Filezilla including the app/script and also disabled the custom virtual host and enabled the default using this command:

sudo a2dissite mydomain.conf sudo a2ensite 000-default.conf

then restart using this command: sudo systemctl restart apache2

I now uploaded the script on the default one which the document root is var/www/html using Filezilla and do the configurations shown above. I also extracted the file before uploading it.

So, after everything, when I visited my site using the IP Address I found this error: “UnexpectedValueException The stream or file “/var/www/html/myapp/storage/logs/laravel.log” could not be opened: failed to open stream: Permission denied”

but when I visit the site using the domain name I also found this error: “Not Found The requested URL was not found on this server”

Again, when I uploaded the composer, I didn’t complete the rest steps, I only uploaded the composer and stopped there, I didn’t go further to set dependency and others because that part on the guide is complicated for me, I didn’t understand it at all. This is the guide below: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-composer-on-ubuntu-18-04 So, I don’t know if that is part of the problem am facing now.

I also found some articles on the web to solve this error. the command given there didn’t work for me. These are the commands and the responses I got when I run them:

sudo chown -R $USER:www-data storage : No such file or directory sudo chmod -R 777 storage : No such file or directory chown -R www-data:www-data /var/www/html/laravel: No such file or directory composer install : composer could not find a composer.json in /root

Please everyone what do I do to solve this problem to get my site working fine. Thank
