Permission Denied on mkdir php with nginx

Question

I am struggling with an issue on LEMP stack. I cannot make my nginx user to create directory via php script.

My stack is RHEL 7.2 NGINX MariadB PHP

I installed the stack successfully and used following code for creating directory in index.php

        <?php
           echo(exec("whoami"));
           mkdir("test",0777,true);
           $error=error_get_last();
           echo $error['mssage'];
        ?>

Output nginx mkdir(): Permission denied

Nginx excecutes PHP via nginx user.

Applied 'chown -R nginx: nginx <working folder>'
Applied 'chmod -R 0777 <working folder>

But above script gives same permission denied error.

My plan is to install Wordpress and import sites to this web server. But since permission is denied on working folder of nginx , Wordpress is not able to create new directories or move content from one folder to other.

Answer 1

Set SELINUX to disabled or permissive in /etc/selinux/config

If SELINUX has to be Enforcing, use semanage to change the context of the MySQL datadir and its contents.

shell> sestatus

SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted

then you have SELinux on.

Answer 2

check your nginx.conf file from /etc/nginx

and get the nginx username using

 sudo nano /etc/nginx/nginx.conf

For example if the username is www-data then use

sudo chown -R www-data /home/www/ || /foldername/

then go to your file directory

cd /home/www/

check the permissions in shell using

ls -l

Now check the mkdir() in your development
