    Like for example, I want to password protect /install/ directory and /admin.php.
    What command should I execute?
    Thanks

    Nginx 1.15.x
    MariaDB 5.5/10.x
    Update FAQ item 13 outlines how to password protect directories and files.


    Same as outlined at Nginx and vBulletin Connect 5 Vhost and PHP-FPM - PHP Warning: require(): Unable to allocate memory for pool. Also official documentation Module ngx_http_auth_basic_module

    Use htpasswd.py script at /usr/local/nginx/conf/htpasswd.py to setup username and password using following command:

    Code:
    python /usr/local/nginx/conf/htpasswd.py -b /usr/local/nginx/conf/htpasswd yourusername yourpassword
    change /usr/local/nginx/conf/htpasswd filename and path for your unique filename and yourusername and yourpassword to unique values of your own

    or use the htpasswd.sh script i wrote in post 28 in this thread

    Code:
    wget -O /usr/local/nginx/conf/htpasswd.sh https://gist.githubusercontent.com/centminmod/3068afbed67d5fe5e2dd/raw
chmod +x /usr/local/nginx/conf/htpasswd.sh
    Code:
    /usr/local/nginx/conf/htpasswd.sh

/usr/local/nginx/conf/htpasswd.sh {create|append} /usr/local/nginx/conf/htpasswd user1 pass1

    So I can't create a separate username/password for admin.php and /install?

    If I understand correctly, If I want another set of account, all I have to do is change/create new passwd file?
    Like:
    Code:
     python /usr/local/nginx/conf/htpasswd.py -c -b /usr/local/nginx/conf/htpasswd2 username password

    yeah can run the command anywhere and if you want separate user/pass files need to have different filenames from /usr/local/nginx/conf/htpasswd

    i.e.

    /usr/local/nginx/conf/htpasswd_install
    /usr/local/nginx/conf/htpasswd_admin

    I understand the concept now :)
    Thanks a lot!
    This is a problem when I have 3 other admins and both of us don't have static IP.

    This code doesn't work:
    Code:
    location /admin.php {
     auth_basic "Private";
    auth_basic_user_file /usr/local/nginx/conf/htpasswd_admin_php;
        }
    Why?

    because locations usually match directories not files with the way you had it before

    Wait I have set a password with number+letters like: 12345pass
    If I enter a password that just 12345 it accepts, why?
    Should be wrong password.

    I already tried changing the password, still encountering the issue.
    I tried to use a password: thisdirprotected
    When I just input a password like thisdirprotecte (missing last letter d) still accepted :(

    I tried with the htpasswd as well as htpasswd_admin_php file both do not accept incomplete missing characters for usernames but do for passwords !

    Code:
      location ~ ^/(admin.php) {
     include /usr/local/nginx/conf/php.conf;
     auth_basic "Private";
     auth_basic_user_file /usr/local/nginx/conf/htpasswd;
        }
    Code:
      location ~ ^/(admin.php) {
     include /usr/local/nginx/conf/php.conf;
     auth_basic "Private";
     auth_basic_user_file /usr/local/nginx/conf/htpasswd_admin_php;
        }

    Wait, I don't have problems on /admin.php
    But on /install/, here's my code:
    Code:
    location /install/ {
    index index.php index.html index.htm;
    include /usr/local/nginx/conf/staticfiles.conf;
    include /usr/local/nginx/conf/php.conf;
    auth_basic "Private";
    auth_basic_user_file /usr/local/nginx/conf/htpasswd_install;
        }
