Magento 2.4 Community Edition on CentOS 8 and Nginx

[kanchevout612a]

Hi all,

I am new to Magento and i started learning the platform for couple weeks now. I have working installation of Magento on Ubuntu with Apache2 as this seems to be the easiest method i found.

Now i am trying to get this working on CentOS 8 with Nginx.

So i have installed my Nginx and i have php-fpm:remi7.4

I already installed Magento without issues. However when i try to open the main page or admin page i get nothing.

I created  /etc/nginx/conf.d/magento.conf with the following content

upstream fastcgi_backend {
server unix:/run/php-fpm/magento.sock;
}
server {
listen 80;
server_name 172.30.53.125;
set $MAGE_ROOT /usr/share/nginx/html/magento2;
set $MAGE_DEBUG_SHOW_ARGS 0;
set $MAGE_MODE default;
include /usr/share/nginx/html/magento2/nginx.conf.sample;
}

Also i have created /etc/php-fpm.d/magento.conf with contents

[magento]
user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx
listen = /run/php-fpm/magento.sock
pm = ondemand
pm.max_children = 50
pm.process_idle_timeout = 10s
pm.max_requests = 500
chdir = /

With this configuration i get HTTP ERROR 500.

If i delete /etc/nginx/conf.d/magento.conf i get Nginx and PHP working again, but i cannot open the Magento main page again. I am looking for advise here.

Update. I found this error in the logs:

[error] 948#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Zend_Cache_Exception: cache_dir "/usr/share/nginx/html/magento2/var/page_cache" is not writable

This indicates that the "/usr/share/nginx/html/magento2/var/page_cache" folder doesn't have permissions.

So i tried 

sudo chmod 744 /usr/share/nginx/html/magento2/var/page_cache

And still i get the same error.

Issue fixed. I had to run the commands below:

chcon -R --type httpd_sys_rw_content_t <magento_root>/app/etc
chcon -R --type httpd_sys_rw_content_t <magento_root>/var
chcon -R --type httpd_sys_rw_content_t <magento_root>/pub/media
chcon -R --type httpd_sys_rw_content_t <magento_root>/pub/static
chcon -R --type httpd_sys_rw_content_t <magento_root>/generated

And then i had to do 

chown 777 <magento_root>
