bitnami - Change phpmyadmin url and access using public IP

Since we are going to make the url public, it is good practice if we make it non-predictable.
sudo nano /opt/bitnami/apps/phpmyadmin/conf/httpd-prefix.conf
Alias /phpMyAdminZAQWDCFRTdf1236 "/opt/bitnami/apps/phpmyadmin/htdocs"

Now give the privileges to make it public.

sudo nano /opt/bitnami/apps/phpmyadmin/conf/httpd-app.conf
<IfVersion >= 2.3>
Require all granted

bitnami mysql password
cat /home/bitnami/bitnami_application_password
This is wp-admin password / mysql root password
cat  /home/bitnami/bitnami_credentials
