What extra modules I could need to help speed up the site ? php version is 7.4

I have CentOS 8 I installed LAMP, Varnish, etc.

I setup hosts

/etc/hosts

ip site1.com www.site1.com ip site2.com www.site2.com

I setup Apache like this:

/etc/httpd.conf to include sites-enabled/ I have sites-enabled and sites-available with two configurations, site1.com.conf and site2.com.conf

Here what I included in etc/httpd/conf/httpd.conf

IncludeOptional sites-enabled/*.conf

Still it is not working. Any idea how to fix this?

I have sites-enabled and sites-available with this *.conf:

<VirtualHost *:8080>
    ServerName ip
Redirect / 301 external_site
</VirtualHost>

and 

<VirtualHost *:8080>
    ServerName site2.com
    ServerAlias www.site2.com
    DocumentRoot /var/www/site2.com/html
    ErrorLog /var/www/site2.com/html/log/error.log
    CustomLog /var/www/site2.com/html/log/requests.log combined
</VirtualHost>

I manage to get this to work now but the https versions are not working, how to fix the https versions ?

I generate 2 ceritficates using mod_ssl

I put 1 of them in /etc/httpd/conf.d/httpd.conf ...

Fixed: Problem was misconfiguration of /etc/httpd/conf.d/ssl.conf

I have CentOS 8 I installed LAMP, Varnish, etc.

I setup hosts

/etc/hosts

ip site1.com www.site1.com ip site2.com www.site2.com

I setup Apache like this:

/etc/httpd.conf to include sites-enabled/

I have sites-enabled and sites-available with two configurations, site1.com.conf and site2.com.conf

Here what I included in etc/httpd/conf/httpd.conf

Include conf.modules.d/*.conf

and

IncludeOptional sites-enabled/*.conf

Still it is not working. Any idea how to fix this?

What i put in site1.com.conf example:

<VirtualHost *:8080>
    ServerName site1.com
    ServerAlias www.site1.com
    DocumentRoot /var/www/site1.com/html
    ErrorLog /var/www/site1.com/html/log/error.log
    CustomLog /var/www/site1.com/html/log/requests.log combined
</VirtualHost>

kdevtmpfsi this is miner or something who knows using a simple hack he managed to get in server using redis and put his mining crap here or who know what it is.

How i stop this from ever happening again

I've installed MySQL version 10.5.0-MariaDB is EOL software by mistake what should I do now server in production? What should i do ? wait for a new release since everything seems to be working fine. Or what you guys suggest ?

Is it even possible to downgrade to 10.4 stable considering this is a production server with a database on it ?

I have CentOS 8, php 7.4 but mariadb 10.5 the eol software :(
