.htpasswd - Nginx password protect root, and separate password for subdirectory -

i'm trying set basic http authentication nginx that's multi-layered. i'd have 1 username & password entire site except subdirectory (url), , separate username & password subdirectory. if navigates subdirectory, want them prompted subdirectory-specific credentials only, , not ones site root.

how set up?

reference: http://nginx.org/en/docs/http/ngx_http_auth_basic_module.html

assume subdirectory url http://www.example.com/admin/.

step 1: create 2 files storing username/password (encrypted) pairs using htpasswd

# secure admin site htpasswd -bc /tmp/admin_passwd.txt admin adminpassword # secure main site htpasswd -bc /tmp/site_passwd.txt user userpassword 

step 2: set nginx config:

server {     listen                      80;     server_name                 www.example.com;     root        /tmp/www;      location ^~ /admin/ {         auth_basic           "secured site admin";         auth_basic_user_file /tmp/admin_passwd.txt;     }      location / {         auth_basic           "secured site";         auth_basic_user_file /tmp/site_passwd.txt;     } }
