How can I put content on an external disk? autoindex

Hello, Im Eloy, i have a server on nginx, this is my virtual server

server {
listen 80 default_server;
listen [::]:80 default_server;

root /var/www/html;

index index.html index.php;

server_name _;

location /data/ {
autoindex on;

}

# This option is important for using PHP.
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
}
}


My configuration of server

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
worker_connections 768;
# multi_accept on;
}

http {

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

include /etc/nginx/mime.types;

#mail {
# # See sample authentication script at:

#
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";

#
# server {
# listen localhost:1ccc;
# protocol pop3;
# proxy on;
# }
#
# server {
# listen localhost:1ccc;
# protocol imap;
# proxy on;
# }
#}

Me he dado cuenta que yo solo tengo 768 worker conecctions y que el tiene como 1024, luego ya no

Luego tiene esto

server {
listen 80;
server_name localhost;
root html;

access_log logs/host.access.log main;

# Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
location ~ /\. {
deny all;
access_log off;
log_not_found off;
}

}

}




I tried put this chown -R www-data:www-data /media/odroid/Maxtor/data/

chown -R www-data:www-data /usr/local/nginx/html/

service nginx destroy && service nginx start


But it has not taken effect, and I still have no permissions, even putting root.


I just want to leave the data folder on an external hard drive.

Since it is currently inside the html folder.

Thank you my web page is very old www.eloy.mooo.com
