In the interim, I've decided to set up a Multi-tier wordpress stack.
What I would now like to know, is the best way to run multiple instances of Wordpress on it.
I imagine I'll need to set up additional databases on the database server, and install additional instances of Wordpress application on the app server. Are the instructions found here sufficient? It doesn't look like they are, as there is no mention of setting up additional database for each instance.
I have followed those instructions. But when I run the installer, it eventually asks me to enter a username, real name, email address, and mysql password. I enter the mysql password that was set for this server instance, and it comes back with the message:
Warning: The installer was not able to connect to the MySQL server. Please make
sure MySQL is running and introduce a valid password to connect to the MySQL
I've not been able to get past this point.
Is this because the DB is on another VM ?
What's the way to proceed?
