<h2>Issue with file permissions</h2>
Sometimes, it's an issue with file permissions. The user in your <code>user</code> directive should at least have read and write permissions to the file you're trying to access.
<h3>The following is a fix for this issue</h3>
nginx can be any user in the ff example
example:
<pre><code>user nginx;


server {
 root /root/user/web/html;
}
</code></pre>
<code>groups nginx</code> to check the group of nginx. 
In my system, I've grouped nginx to www-data group. This is the output: <code>nginx: www-data</code>. 1st part is the user and 2nd part is the group.
<code>ls -al /root/user/web/html</code> to see if nginx owns the folder 
It should output this:
<pre><code>drwxr-x--- 2 nginx www-data 4.0K Aug 24 14:52 .
drwxr-x--- 4 root root 4.0K Aug 23 17:16 ..
-rwxr-x--- 1 nginx www-data 24 Aug 24 14:26 index.html (or some other file)
... Some more files
</code></pre>
<a href="https://www.pluralsight.com/blog/it-ops/linux-file-permissions" rel="nofollow noreferrer">This guide shows the basics of file permissions</a> 
But a summary of this: 
3rd column is the owner. If it's the same as the <code>user</code> directive, the first row should have <code>drwx</code> in its 1st column, which means that <code>/var/www/html</code> is a directory (<code>d</code>) owned by <code>nginx</code> with <code>r</code>ead, <code>w</code>rite, and e<code>x</code>ecute permissions.
The following <code>r-x</code> means that the group (4th column which is <code>www-data</code> in my case) have <code>r</code>ead and e<code>x</code>ecute permissions, but no <code>w</code>rite permissions. If the folder is not owned by the user in the nginx <code>user</code> directive, the folder should be owned by the same group that the user (<code>nginx</code>) is in which is <code>www-data</code> in my case.
And the last <code>---</code> means that other users don't have any permissions at all.
<a href="https://www.internalpointers.com/post/right-folder-permission-website" rel="nofollow noreferrer">Here's a guide in updating file permissions</a> 
Or a summary: 
Replace <code>nginx</code> with your desired user and <code>www-data</code> with your desired group
<pre><code>chown -R nginx /root/user/web/html/
chgrp -R www-data /root/user/web/html/
chmod -R 750 /root/user/web/html/
chmod g+s /root/user/web/html/
</code></pre>
This should work if the user has read permissions in the folders that lead to /html/, which are /root/, user/, and web/

I'm using nginx in linux ubuntu as my webservice and the default index.php for my localhost is in the <code>/www/var/html</code>. I'm trying ti change it to other directory, which is <code>/root/user/web/html</code>. My configuration at <code>/etc/nginx/sites-enabled/default</code> :
<pre><code>server {
 listen 80 default_server;
 listen [::]:80 default_server;
 root /var/www/html;

 index index.html index.htm index.php;
 server_name _ localhost;

 location / {
 try_files $uri $uri/ =404;
 }
 location ~ \.php$ {
 include snippets/fastcgi-php.conf;
 fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
</code></pre>
however, when i tried to change <code>root /var/www/html;</code> to <code>root /root/user/web/html;</code> the localhost said 404 Not Found (i have already checked the path of directory i want to use using pwd command and it resulted /root/user/web/html). Is there anything i could change or do in order to fix this? Thankyou
