Cloud9 – Setting up and using phpMyAdmin MySQL web interface

This page – https://community.c9.io/t/setting-up-phpmyadmin/1723 – says it all, but here are the keys points again:

Using PHPMyAdmin with Cloud9

First, create a PHP workspace so you have PHP, MySQL, and Apache installed right away. You can then make sure you have MySQL installed by running:

mysql-ctl install

Then install phpMyAdmin:

phpmyadmin-ctl install

After the installation is complete you’ll just want to make sure mysql is running once more:

mysql-ctl start

After installing phpMyAdmin, you were given a link to access PHPMyAdmin which will follow the pattern of: https://[workspacename]-[username].c9users.io/phpmyadmin. From that link, you can log in with your Cloud9 username and a blank password.
