Installing WordPress on your computer gives you a perfect testing ground for experimentation, theme development, plugin testing, and website development. This course is designed for developers and users who want to install and configure WordPress locally on a Mac with MAMP, the open-source server/database/scripting language combo that sets the stage for more serious WordPress development. Author Morten Rand-Hendriksen covers the configuration options and usage scenarios to get you started working in WordPress quickly.
For WordPress to be able to work under MAMP on your computer, it needs a database to place settings and content information into. That means we need to create a database for WordPress and then tell WordPress how to access it. Creating that database will be done through MAMP. But before we do that, let me just show you why we need a database to begin with. If I open MAMP and I start the servers, I'll be taken to the MAMP configuration page.
But I also started the servers so that we can access WordPress from our browser. So I go and open a separate tab, and I'll go directly to WordPress. Now because we've configured MAMP's Apache server to point directly to the WordPress folder, we can access WordPress by going to localhost:8888. If we do that, we get this warning page that says There doesn't appear to be a wp-config.php file for WordPress, which means we can't start.
The problem is even if we try to create a configuration file right now, you'll see that we need a database to do so. So before we get to this point, we need to create the database. I'll go to the MAMP configuration page in my browser. Then I'll go to this tab called phpMyAdmin. This is where I can create new databases and manage my databases. From here I'll click on the Databases tab and then it says, Create Database.
So here I can create a new database. I'll call the database mywp, my WordPress, and I'll click Create. Now we can see down here we have a new database. Of course, if I go to the database, it's empty. But that's fine because WordPress will populate this database for us. Now that I have a database for WordPress, I can configure WordPress to talk to that database. So I will go back to WordPress here. If you remember, I opened it by going to localhost:8888, and now I can create a configuration file.
So I'll click on the button. Now WordPress will tell me what it needs to be able to set itself up. I need the Database name which is what we've already installed. It's mywp. We also need a username and password, and the default username and password inside MAMP are root and root. We also need a database host. The host in this case will be localhost. I have all these information. So I'm going to click the Let's go! button. And from here I need to insert all that information.
So I'll put in my Database Name, mywp, my User Name, which like I said is root. The Password is the same, root. Then the Database Host is the localhost and the Table Prefix, the default is wp_, and we can just leave it like that. I'll click Submit. And WordPress now creates a new configuration file for me containing all that information. Because everything worked, I get to this page that says All right sparky.
You've made it through this part of the installation. I'll click Run the install, and now I get to the landing page for a new installation of WordPress. To finalize the process, all I need to do is give my Site a Title. So I'll call it MyMAMPwp. I set a Username for myself. So I will set a username morten. I have to have a password. So I will set a password. I also have to set an email from myself. So I will say, now, because this is a WordPress installation running on my computer, there really is no point allowing search engines to index the site, because search engines can't access my computer.
So I will uncheck this Allow search engines to index this site box. Then I'll click Install WordPress. Now WordPress is fully installed, and I can either click Log In to log in, or I can simply go back to localhost:8888 and here you see, a fresh installation of WordPress running locally on my computer.
