Hello

I'm currently stuck in the configuration of the server for Matomo/Piwik statistics. Can you please help me in resolving this configuration.
I want that nginx redirect all the trafic for URL https://www.mysite.com/matomo to /var/www/matomo root folder.
Here follow the 2 files used to configure the server running Magento 2:

***************** FIrst file

upstream fastcgi_backend {
server unix:/run/php/php7.2-fpm.sock;
}

server {
listen 80 default_server;
server_name mysite.com www.mysite.com;
return 301 https://$server_name$request_uri;
}

server {
listen 443 default_server;
server_name mysite.com www.mysite.com;
set $MAGE_ROOT /var/www/mysite;
include /var/www/mysite/nginx.conf.sample;
ssl on;
ssl_certificate /etc/ssl/ssl.crt/mysite.crt;
ssl_certificate_key /etc/ssl/ssl.key/mysite.key;
}


***************************** second file

## Example configuration:
# upstream fastcgi_backend {
# # use tcp connection
# # server 127.0.0.1:9000;
# # or socket
# server unix:/var/run/php/php7.0-fpm.sock;
# }
# server {
# listen 80;
# server_name mage.dev;
# set $MAGE_ROOT /var/www/magento2;
# include /vagrant/magento2/nginx.conf.sample;
# }
#
## Optional override of deployment mode. We recommend you use the
## command 'bin/magento deploy:mode:set' to switch modes instead.
##
## set $MAGE_MODE default; # or production or developer
##
## If you set MAGE_MODE in server config, you must pass the variable into the
## PHP entry point blocks, which are indicated below. You can pass
## it in using:
##
## fastcgi_param MAGE_MODE $MAGE_MODE;
##
## In production mode, you should uncomment the 'expires' directive in the /static/ location block
