redirect ALL traffic to https. NGINX - nginx

Question

I am trying to redirect all traffic to https://example.com no matter what the user types in.
The following .conf file is very close but it does not catch http://example.com
what would you suggest that I change in order for ALL traffic to redirect to https://example.com ?
Thank you.
server {
listen 80;
listen 443;
server_name www.example.com;
return 301 https://example.com$request_uri;
}
server {
server_name example.com;
access_log /var/log/nginx/example-access.log;
error_log /var/log/nginx/example-error.log;
root /var/www/html/web;
index index.html index.htm index.php;
location / {
try_files $uri $uri/ /index.php$uri?$args;
}
rewrite ^/backend\.php/?(.*)$ /$1 permanent;
location /admin {
index admin content backend.php;
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /backend.php/$1 last;
}
location ~ "^(.+\.php)($|/)" {
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
}
}

Answer 1

Add another server record for http://example.com.
server {
listen 80;
server_name example.com;
return 301 https://example.com$request_uri;
}
Also, make sure that the main server-record only listens on port 443, so add this to it:
listen 443 ssl;

Answer 2

Use separate server blocks.
server {
listen 80;
server_name www.example.com
example.com;
return 301 https://example.com$request_uri;
}
server {
listen 443;
server_name www.example.com;
return 301 https://example.com$request_uri;
}
server {
server_name example.com;
access_log /var/log/nginx/example-access.log;
error_log /var/log/nginx/example-error.log;
root /var/www/html/web;
index index.html index.htm index.php;
location / {
try_files $uri $uri/ /index.php$uri?$args;
}
rewrite ^/backend\.php/?(.*)$ /$1 permanent;
location /admin {
index admin content backend.php;
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /backend.php/$1 last;
}
location ~ "^(.+\.php)($|/)" {
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
}
}
