Upload the WordPress extracted files to your localhost

Step 2: Now, if you need to upload the extracted files and folders to your live web server.    Use an FTP program to upload the installation files.   I use "FileZilla".    If you want to download this program visit: FileZilla Download. For detailed information on how to use "FileZilla" - check out: FileZilla Tutorial.

IMPORTANT!
Make sure to put your main WordPress installation in your account.   Upload the extracted files to your main public_html folder.

You can also use the cPanel -> File Manager -> Upload file(s).

Create a MySQL Database

At this time, you need to create a MySQL database and assign a user to it with full permissions.

We will use the "phpMyAdmin" installed to create your database.  You can also use the cPanel if you have access to it.

---

Use phpMyAdmin:

If the database doesn't already exist in the Database dropdown on the left, create one.

• Choose a name for your WordPress database.
• 
• Enter the chosen database name in the "Create database" field and choose the best collation for your language and encoding. In most cases it's better to choose in the "utf8_" series or choose "utf8mb4_general_ci" if the language "utf8_" doesn't exist.
• Click the "phpMyAdmin" icon in the upper left to return to the main page, then click the "Users tab".
• 
• Click "Add user".
• 
• Choose a username for WordPress and enter it in the User name field. Make sure the "Use text field" is selected from the dropdown.
• 
• Choose a secure password (ideally containing a combination of upper- and lower-case letters, numbers, and symbols), and enter it in the Password field. (Be sure Use text field: is selected from the dropdown.) Re-enter the password in the Re-type field.
• Write down the username and password you chose.
• Leave all options under Global privileges at their defaults.
• Click Go.
• Return to the Users screen and click the Edit privileges icon on the user you've just created for WordPress.
• 
• In the Database-specific privileges section, select the database you've just created for WordPress under the "Add privileges" to the following database dropdown, and click Go.
• The page will refresh with privileges for that database. Click "Check All" to select all privileges, and click Go.
• On the resulting page, make note of the host name listed after Server: at the top of the page.

Installation Process

Installation process is easy. Navigate to your website to start with the installation WordPress process.

Since, you already slided the new WordPress software into your destination folder bring the the "MAMP" admin dashboard. Now, go to the "Preferences..." and click on the "Ports" tab. You will notice that the "Apache Port" and "MySql port" is already set. If you have a webserver already on those ports then proceed to change them for your new "WordPress" installation.

Now, go to the "Web Server" tab and click on the "Document Root" the file manager will display your directories and find the new WordPress" intallation folder. Click on "Select" and the new webserver folder will be selected as your new localhost website.

Now, go back to the "MAMP" dasboard box and click on the "Start Servers" this will start your webserver. You should see the two check options (Apache, MySql) checked. This means that the webservers list active.

Now, that both "Apache" and "MySql" is up and running go to your favorite browser and type: localhost:8888. This will bring up your new "WordPress" installation process.

After you have enter typed in the local URL "http://localhost" - you will get the below screen. Choose the language you want, since I live in the states I choose "English". Continue by clicking on the "Continue" button.

After the "Continue" button was clicked on you will be displayed by a "Welcome to WordPress" dialog message. Make sure you have the database name, username, password and host information. This information is going to populate the "wp-config" file.

You will be displayed with a form after you have click on the "Let's go!" button. Here you will enter your "Database Name", "Username", "Password", "Database Host" and the "Table Prefix". For extra security you might want to change it to your preference. Since, I am installing WordPress on my local host I will keep the default. Now, click on the "Submit" button. See below:

At this point you have gone through the database connection installation. When you click on the "Run the installtion" button you will be ready to communicate with WordPress.

On the next screen, you will have to enter the information about your administrative username and the title of your new site. In addition, you can specify whether you'd want search engines to index your site or not. Once you fill in that information, press the Install WordPress button. Bear in mind, however, that you should specify a real email address. It can be later used in case you forget your password.

Once, the process of the installation completes successfully you will get the below dialog box. Click on the "Log In" button logon to your new WordPress website.

Once, you have clicked on the "Log In" button you will receive the following login form. Enter your username, password click on the "Log In" button.

Once, you log in you will be taken to your WordPress environment. Here you can start building your website. You can create "Post" for your blog and create your standard web pages.

How to access install themes functionality from the WP admin dashboard

The first thing you need to do when you want to install a new WordPress theme is to log in to your site admin page. Once there, go to Appearance -> Themes.

Here, you will see all the themes you have currently installed in your application. To add another one, simply click on the "Add New" button.

Search the theme you want by entering theme name to "Search themes.." box. You will be displayed with several themes.

Once, you find the theme you want to use click on it and you will be presented with the "Install" button.

Once, you install the theme you will want to click on the "Activate" button. This will make the theme your main activate theme. The theme the public will see when they visit your site.

Install a theme from the official WordPress theme directory

The easiest way to install themes to your WordPress site is if they are listed in the official themes directory. This allows you to search for the theme you need directly from your site admin page. Each theme in the official directory has to have Tags that describe its functionality allowing you to easily search for the right theme.

If you know the theme's name, you can simply search for it.

However, usually, that's not the case. This is why you can use the Feature Filter. For example, you can search for a E-Commerce, Two columns theme that has Flexible Width. Simply check those tags and press the Apply Filters button.

You will now see all the themes that meet your search. Hover over any of them and you will see two options - to see a demo of the theme or to install it. Once you choose which theme you want to use for your site, press the blue Install button.

Your WordPress application will download and install the theme for you. Simply click the Activate link on the next page you will be redirected to.

Upload a theme you have already downloaded

If you have a theme that's not listed in the WordPress.org directory, you can simply upload it from the Themes -> Install Themes section in WordPress. To do this click on the Upload link at the top of the page.

Now, click the Choose File button, select the archive of your theme from your local computer and press the Install Now button.

In a few seconds, WordPress will upload and extract the theme archive for you. All you need to do next is to press the Activate link under the message for successful theme installation.

That's it! You can now go to the front end of your site and see the newly activated theme.
