Basic Authentication with Nginx with proxy port (react/node app etc)

Reference: https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/

Requirements: apache2-utils or httpd-tools

Use htpasswd utility and create a .htpasswd file, see reference

After that, just add lines in nginx conf

location / {
	auth_basic "Backend Area";
    auth_basic_user_file /root/.htpasswd; ## path to your passwd file
	## ...
	## xyz code
	##... 
	proxy_pass http://127.0.0.1:4000; ## Proxy port for your app
	proxy_set_header Authorization ""; ## DONT FORGET THIS. reset the auth header
	include proxy.inc;
}

Restart nginx now or test first using “nginx -t”

SELECT * from wp_usermeta where `meta_key` like 'edit_%_per_page'

So probably you chose “Number of items per page” as 1000 or 200 and now the page doesnt load anymore because your database ran out of memory.

If that is the case, run the above query on phpmysql or any other way, edit the numbers and fixed!
