The other day I was working on Google Compute Engine, and I setup a new WordPress site on the Google Compute Engine. I run into an issue with phpMyAdmin as it gave me an warning when I tried to access it through the web browser, the message “For security reasons, this URL is only accessible using localhost (127.0.0.1) as the hostname”
The Google Compute Engine is using bitmani to deploy apps into the cloud, so when I selected the WordPress installation in Google Compute Engine, I I used the bitmani wiki to find answers about how to use phpMyAdmin.
What I had to do was to setup a SSH tunnel
ssh -N -p 22 <username>@<ip address server> -L 8888/localhost/80
You could also use programs as putty or other similar applications to make this happen.
After you open the SSH tunnel you access the phpyAdmin in your browser like this – 127.0.0.1:8888/phpmyadmin
