When we tried to setup WordPress in Mac we encountered issue related to database connection. Following is the issue:
Error establishing a database connection
In WordPress setup it is usually a common practice to use MySQL database on the same machine which is localhost. So the database host becomes the localhost.
The WordPress default setup comes with default wp-config.php there it has like this:
/** MySQL hostname */ define('DB_HOST', 'localhost');
Mac OS can not determine the database host using localhost. It understands the localhost as the IP: 127.0.0.1
We had to use the local IP instead of localhost like below:
/** MySQL hostname */ define('DB_HOST', '127.0.0.1');
