htpasswd -c /etc/nginx/.htpasswd usernamethatyouwant chmod 644 /etc/nginx/.htpasswd
After that, just add lines in nginx conf
location / { auth_basic "Backend Area"; auth_basic_user_file /etc/nginx/.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”
