I finally managed to install Mautic !!!
Here is information about the problem I had in my environment to help the community.
Basically being able to discover that the problem was in the process of creating the Mautic tables. To reach this understanding, I ran the following command from the Mautic console on the command line:
$> php bin/console mautic:install:data
This command recreates all the Mautic tables, to my surprise, this process took more than 40 minutes to complete. That’s when I started to analyze the MariaDB settings and arrived at this configuration in the /etc/my.cnf file
#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]
#
# include *.cnf from the config directory
#
!includedir /etc/my.cnf.d

As the script’s execution time is very long, the page falls due to time out and we received the famous error 500.
After all the settings, I started the installation process via the browser again.
If after all these configurations, you still return error 500 (you will be YOURDOMAIN.COM/installer/step/1.1), you must wait for the process of creating the tables to finish (check the processes running on MySQL) when finish, simply change to YOURDOMAIN.COM/installer/step/1.2, so the installation process will continue.
Summing up:
If error 500 occurs in step 1.1:
YOURDOMAIN.COM/installer/step/1.1
After creating the tables, change to step 1.2:
YOURDOMAIN.COM/installer/step/1.2
And finish the installation.
